Not sure why Apple restored it yet again this far into Otherwise, all is well on From the comment I assume you used the Combos more likely to reinstall plist but even deltas may do so sometimes. Best to be prepared regardless. Other Replies the OS X Some later reports from Sept.

Just removed the PlatformSupport. Well, I was surprised to discover that it was indeed there after the previous updates did not restore it. As with previous updates, Activity Monitor revealed to be mdsworker doing its stuff choking both cores. Maybe they do but are not as aware or do not notice it. Some later Yes, onboard sata has big drive support for much higher capacity, but largest 2. Check drive heights before buying, as I think your mini's max is 9.

Drive reads BRD fine, need player if this is to be a media box. There's a "Mac" blu-ray player app www. I've not kept up with VLC media player for a long time but maybe someone else can better answer this question. There's some media center software for Macs XBMC , Plex , maybe others especially for those that like 'non disc' media. Again I'm not the best person to ask about that, sorry. I had linked to a reader's core solo Mini Media Center project page years ago but it was a. Mac website and is now Try googling on the subject.

64bit CPU Upgrade Tutorial – 32bit CPU Mac Series ep.6

And I'd see what freeware Temperature Monitor reports on your system. Thanks for the tips, and good modding to you all. I refused to upgrade to Lion because the USB This had to to with Spotlight indexing and some other optimizations that the kernel does with every fresh Mac OS X installation. I'm impressed with the cooling efficiency of Lion vs. Snow Leopard. So I backed up the data to a Time Capsule before erasing the internal drive. The mini booted back perfectly without issues, also reporting the same temperature readings as with the external drive once "mdworker" finished doing its thing.

How much did I spend on all this? Worth every penny. Thanks Mike, I would not have done this if not because of your very informative report section on this helpful site. Trouble was it wouldn't run new version of word so I couldn't open the document. And, thanks to this page, so it began Upgraded firmware to 2. Mini 1,1 to 2,1 - Ref: System memory map related I assume. Older posts years ago and mac upgrade vendors have also listed that limitation.

Here's clip from OWC's Mac upgrades page note: Then thought an SSD would be nice. Problem that it was SATA 2 and although supposedly "backwards compatible" to SATA 1 - it wasn't - without a firmware upgrade didn't work this out until installs from TimeMachine loaded up and then apps started dropping out. To do the SSD firmware upgrade, had to remove the SSD, reinstall the old HDD and burn a boot disk with the new firmware using the mini our only writable disk drive and then boot update? Per this www. After this it went like a rocket. Installed office for mac original purpose lost in the mists of time!

Or no Then decided to upgrade cpu and get to lion to access a TM backup Temperatures OK if not pushing it with lid off, 1 rivet in place and some arctic 5 thermal compound. Will be slightly more comfortable once ebay member finally ships my replacements 20mm M3 bolts which I ordered in anticipation thanks to someone else on here! So now I have questions Case, drive swap. Is there any way to take advantage of the 3 gigabit link speed in the SSD, rather than the 1.

Reports there generally were on SIL based cards which require a driver install. And not bootable. Your call if you want to try installing the unofficial OS X univ trim enabler. Taking the mini apart was quite easy. Didn't need to use a putty knife as many of the guides say. I used a Swiss army knife and the bottle opener part. Lid popped off very easy and I did follow the ifixit guide which has great pics. New CPU in, thermal paste and all back together. Had a bit of trouble getting the lid back on as I caught the silver bits of the chassis.

Lid back off and next attempt the lid wiggled on avoiding the silver bits. Never higher. Lion Install - this is where I had trouble as there are many ways to achieve this and it can be confusing Below I post a step by step that hopefully others may benefit from it. I have 2 macs. A inch iMac and the above mentioned Mac Mini. Because I have this setup, I used the target disk mode install.

Steps below.

Welcome Image and Text

If not already owned Buy FireWire cable. Place both macs together so the FireWire cable can reach them both. Plug cable in. I copied the Lion Installer to the desktop so it was easy to get to. The installer would start, I would choose the mac mini HD, the install files would copy across in about 3 minutes, then the iMac would restart.

Upon restart I was faced with a selection of disks to choose. Nowhere on the web could I find the answer to this. Every guide just says " install via target disc mode" and that's it. I changed them to different names - iMac HD and MacMini HD, although renaming one would have sufficed and attempted the target disk mode install again. This time when the installer copied the files and then restarted the iMac, the installer simply picks up where it left off and installs Lion to the MacMini HD - Success.

I really wanted to report this here as it might help others. Just make sure your HD's don't have the same names. Boot up mac mini to target disc mode. Many guides say to simply hold down the letter T when powering up the mini. This did not work for me on several attempts.

Go into system prefs, startup disc, and click the target disc mode button. The mini will reboot to TDM. Use whatever method works for you. Not important. The MacMini hd should now be mounted and visible in Finder and on the desktop. Find the lion installer and double click on it. The installer will start. When the installer gets to the disc selection window it will be defaulted to the iMacs hd.

Simply click the " other disc, more options " button to see all the discs you can install to. Find your MacMini hd disc, select it and continue. What will happen now - the Lion installer will copy about 3 minutes worth of data to the mac mini HD via the FireWire cable. When these files are copied the Lion installer will need to reboot the iMac so that the Lion installer can actually install Lion. When the iMac reboots the Lion installer will automatically continue with the Lion install.

It will take about 30 minutes and a progress bar will be visible counting down the minutes. Once Lion finishes the install it will restart the iMac. No big issue and it does boot from it too.

Mini 2.1 (2007) with os 10.8?

Your mac mini should still be in Target Disk Mode as we have not touched it during this install. If it isn't make sure it is. Even though the Mini 1,1 has been upgraded with a supported Core2Duo CPU, Lion still won't run from the "unsupported" Mini model as long as the standard unedited supported models plist file is present. Some have edited the file but most just delete it. We will delete the plist file in the terminal. Open terminal and follow these commands: Type your password and hit enter.

The file will be deleted. Turn the mac mini off by hitting the power button on the rear of it. Turn the mac mini on. The mac mini should boot up as normal to OS X Lion. Before doing any software updates have a read through this page of reports as the plist file we removed might be put back by some updates esp.

Don't panic if this does occur, you can put it back in target disk mode and use the commands above to remove the plist file again. Sorry if this guide seems very basic to many of you but I wanted to do a step by step for those wondering if they could attempt it. Put mac mini in Target Disk Mode ref: I've not installed Lion on anything of mine yet.

Not anything I really needed in I hesitate to even mention this as maybe not an issue anymore but just a FYI in case any issues are seen after renaming a volume that has 3rd party apps installed. I don't have a second - newer - Mac so using target disk mode wasn't an option. I ended up making a bootable USB stick by following the instructions in this forum post Sure enough, at the first reboot I got the blocked symbol so I booted from USB again and deleted PlatformSupport.

I allowed System Update to apply I had to boot from my Lion installer USB stick to delete that file before the operating system would successfully boot once more. Took basically 12 hours to do but the machine is running great and I was able to update the OS to CPU temp running around 50C. Followed the guide at www. I think that was due to the upgraded graphics - ATI x with mb of Vram that I ordered with the machine.

The speed difference is easily noticeable. I think it was a lot easier than what is portrayed on the internet however if someone is a novice and never worked inside say a laptop they will want to avoid the upgrade. Just takes patience and take a lot of pictures to see where every screw and connector goes.

One strange think I noticed is the Wifi card had two antenna connectors on it and there was only one antenna so I really don't know if I'm missing a second antenna or there is a difference in the two connectors. Not sure what card is in this iMac Many cards typically have multiple antennas for MiMo. I didn't get a clear picture of which one of the connectors the antenna had been connected to and after putting it back together the signal reception is half what it had been.

Any chance a wire got pinched or disconnected? Unless it's related to some interference? Thanks for a great site I've been visiting your site since you first started back in the 90's. Tough times the last couple years but thankful to still be around. No problems here. Several If the file was restored, original Core Duo mini models would not boot to Lion as it's not in the standard supported models plist. Per later report above, the Combo I also carried out the mini 1,1 to 2,1 firmware update.

First of all I want to point out that I have more than 30 years of experience opening and doing all kinds of stuff with Macs and computers in general, with different levels of difficulty can I manage to solve and achieve my objective without many issues or obstacles I have to say that this procedure IS easy and I found it to be of no difficulty whatsoever especially after reading so many reports on how easy the whole thing is.

More so after opening my Core Solo mini several times to max out the Memory and replace the hard drive for bigger and faster units. Many things kept me from doing it earlier, first of all the mini is not my main computer, neither the most used among my setups of fairly recent Macs. My main computer, and also the one I heavily upgrade on a constant basis with ease, is a Mac Pro Early that pretty much smokes almost anything out there. It rocks. The mini is a utility computer and my first Intel Mac that I keep around for miscellaneous tasks and common everyday use.

But still, the Core Solo was too long on the tooth to keep dragging around, so I finally opted for a replacement. I searched for a cheap T but I could not find one. At least one that didn't cost half as much as a used Core 2 Duo mini to justify it.

Mac OS Support Guide

So a settled for a chump change T 1. And the price was so cheap like it-could-pass-for-free kind of cheap. Moving on. Opening the mini was, for me, easy like those jarheads that assemble and disassemble their M14s blindfolded I never did it before so this was uncharted territory for me and frankly did not consider it much of a challenge as I had removed motherboards using similar gizmos. I cut my fingers, bend the metal fins on the heat-sink, slashed my knuckles with the metal fins, sweat like a pig and cursed like a demon on fire.

It took me hours. Damn those plastic pins are hard, small and annoying! I realize that the pins were so old and subjected to heat that they petrified to the point that it was impossible to squeeze them through the holes no matter what. I was pissed. Almost broke the logic board in anger and jumped to eBay to buy a used old mini, but then I decided to break the damn things and look for replacement alternatives.

Find out your Mac's OS Capabilities

Temperature is basically the same as before considering the two cores and higher clock speed. One thing that puzzled me, I wanted to install Lion and sampled a test drive by booting it from an external 2. For this reason I'll put the OS upgrade on hold until I find out what's going on. Upgraded 1.

Post OS X Some earlier reports noted updating the firmware to mini 2,1 with 3GB ram support. Another 2. Includes FYI on He's referring to the supported models plist file. Past notes on that here. Did you update to If any C2D updated mini owner tries the It is super easy: Here are the details - the exact process is on page 8. Thanks for a great website. Next step was a firmware upgrade, stepping my Mac Mini 1. I managed to get my hands on a T for 20 Euros, and followed the various upgrade guides available especially the excellent Ifixit tutorial..

The chips were even advertised as being for the mac mini. The various instructions available on the web are a big help but do not adequately address a few things. The screw that holds the motherboard down in the front right corner is longer than the other three. I marked this location on the top of the cd drive with permanent marker so I wouldn't lose track. The airport connector is on an annoyingly short cable. When re-installing connect it first before trying to replace the black plastic shroud holding the computer's guts. When the black plastic shroud is out turn it over and check the fan for dust or problems.

Spray it with a can of air to clean dust out and insure the fan spins well. When removing the motherboard, the sticky heat transfer pad beneath the motherboard will hold the board down. Use something to gently lever the rear corners forward until they break lose and the board can be lifted out. When reinstalling make sure to wipe the bottom chip down with alcohol so it will re-stick cleanly odds are your fingers touched it when the board was loose.

Apple reccommends replacing the transfer pad but unless you have a source you won't be able and will need to reuse it. Once the board is out, turn it over and use needle nose pliers to carefully squeeze the plastic tips, first one side then the other, while applying slight pressure to pinch the end closed and nudge it under the hole edge then the same to the other side. By doing this carefully you can pop first one of the expanded tips into the hole then the other and the spring tension will immediately pull the pin through. I read a lot of horror stories about people breaking these.

They are very similar to the motherboard standoffs used in many pcs but on a much smaller scale. Being familiar with those from building many pcs, I was able to apply the same methods as removing a pc motherboard from the standoffs. Note the position of the heat sink! If you don't, and this is not documented anywhere I saw, you can install it in the wrong orientation -there is nothing to prevent doing it- because the holes are in a square formation they fit. And because the heatsink is rectangular the black plastic shroud will not fit back over and you have to disassemble the heat sink again to correct it.

The thing to remember is the heat sink has about a half inch length in one direction and this points towards the back of the case. When reattaching the heat sink's plastic posts I placed the entire motherboard on a portion of a compartmentalized tray so that the bottom chip area was not touching the table but the board was supported.

I used the same needle nose pliers with their points opened to cover most of the pin head and then to carefully push down the plastic heads until the pin clicked. After all are done, turn over the board and use a hook of some sort to wedge open the pin's legs to make sure they are locked in place.

Dental tools or an A. Dick Stylus work well. That stylus I've used for years to hook and relatch laptop key scissor mechanisms among other things. Once the motherboard is back in the case I reconnected the power button and then connected it to power and a monitor to verify it would start before reassembling further. Once confirmed I put it all back together and it works well.

Tomorrow I upgrade my Pro from two 2. Bought a 2. Ended up using 2 of the nylon screws and nuts as they broke when re-installed. Upgraded to a gig apple sata drive left over from a gig client upgrade Booted to the old drive in a usb case and did carbon copy cloner. Reading now on the lion upgrade which I may do to the old usb case drive and then redo carbon copy cloner. May also get a SSD drive before I put it back together. Working well As noted on the front page news on Feb 6th , Apple pulled the original Delta Earlier reports on SU From Feb 20, mail " I started with When I upgraded to With Instead, I patched the "PlatformSupport.

A quick rundown of how this was done from the terminal: I'm happy to say the I think sometimes we have to expect the unexpected from Apple Best regards, Luca P.

Mac Mini 2,1 max OSX version? - Apple Community

Over the years the Combo updater has often been a fix for those that used Software Update or Delta updates and had problems, including some However it won't be a fix for all of course. But again I was wondering if the Combo updater would reinstall the PlatformSupport. Brian K. He said he was using an edited plist file to add support where others just deleted the plist file but it was overwritten by the Combo updater. The Reports on earlier Lion version updates follow. Warning about That file was deleted as part of the workaround to run Lion on C2D upgraded unsupported macs.

Core2 Duo Upgraded Macs and I'm sorry to say that And having a previous OS version bootable clone handy is a very good idea in general. Well worth the cost of the drive IMHO. Regards and sorry for my bad english. C2D Upgraded mini owner running Lion server sent a note about that. Same fix removing file of course. After acquiring a T 2. All went very well, I was even able to remove the plastic heatsink pins by using an electronics needle nose pliers and very carefully releasing them.

Removing the flat cable connection to the drive board is not a good idea, in my opinion; I removed it, and reassembly was a a bit tricky; it could have very easily been ruined in the process, I definitely won't be doing that again. The results are great so far. The Geekbench score improved from to ! CPU temps seem like they're in the same general operating range as before.

Next I'll have to get an SSD drive Thanks, Mike S. Texas" OS X Some may have been concerned that I wondered if something had changed app store installer change, etc or if this is another case of some detail not evident. My first thought was the plist file was still present, so I asked and he said it was deleted.

  1. double clicking doesnt work mac.
  2. color network scangear for mac os x.
  3. defrag for mac os x 10.4!
  4. Here's his email: I also maxed out the memory to 2GB I did this and almost started celebrating. The next step was to start up the mini normally. Initially it looked as if the start up was going to be successful, then it sort of hiccupped and went back to the snow leopard start up screen. Along with a dialog box stating the system could not be installed on this hardware.

    Based on that message at boot, I thought the supported platform plist file was still present. I asked if he was sure that plist file was deleted - he later replied it was. Lion I used software update to get And another successful Lion on C2D updated Mini report: Also to respond to the performance naysayers, this computer with an SSD is fantastic!

    Keep up the good work, -David J. So snappy it often 'feels' like you bought a new machine. I'd almost forgotten what a difference it was until getting to play with an intern's new MBA. Going back to my rpm HD work machine, opening apps is slow as molasses. Reports that follow are copies from the Aug 17th news page: Today I upgraded to I can't speak for the non-server update but I doubt it would be any different.

    I installed Lion on my 20" white iMac using the destination disk mode hack and removing PlatformSupport. Regards, Luca P" More 2. Already upgraded the memory to 2GB a while ago and then decided to upgrade to a bigger Hard Drive. Whilst browsing for info, I noticed that a cpu upgrade was also possible - so I did that too. Used the OWC video at their DIY Videos page to remind myself how to pull it apart and then the video on this page to remove the motherboard.

    Got the cpu and a packet of nylon nuts and bolts from eBay and some thermal paste from the local computer shop. Everything went smoothly and I even managed not to break or damage the original pins that secure the heatsink. I supported the head of the pin with the flat end of a lead pencil, pressed on the spring and squeezed the flared edges of the pin with a small pair of needle nose pliers.

    If you then release pressure on the spring slowly whilst still squeezing the flared ends, the pin will then pop gently through the board without flying off into your room somewhere. Very happy with the results. Mini is much more responsive with no noticeable increase in heat or fan noise - just as quiet as it ever was! Could have done it for much cheaper using a T 2GHz but couldn't resist the T when one came up. Update from Aug 19th mail Purchased Lion through the Appstore it is now working on the upgraded Mini. But had to take a few extra steps along the way.

    I have no access to a Mac that is supported by Lion so I couldn't do the Firewire target drive process. The Dell then booted up fine and then loaded the Mini HD. System Information reported that I was simulating a MacPro 3. Connected to the Appstore and purchased Lion - downloaded it and then installed it onto my cloned Mini HD. Modified the PlatformSupport. It worked! Deleted the CC clone logs on the external and reformatted the Mini internal drive, then CC cloned the external drive back onto the internal Mini drive.

    Shut down, disconnected the usb external drive and rebooted into Lion on my Mini. Upgraded to Was a bit of a process - but I was determined to do the job without using a hacked torrent from somewhere. Bought T at ebay and the seller included a "special" tool to prevent break off the brittle, springed nylon locks holding the heatsink in place against the CPU.

    Overall I'm very happy, though it was a small jump: These instructions worked great. I have a small handful of extra M3 x 20mm nylon "bolts" actually machine screws and nuts that will replace them. Thanks to the advice on this page I was well prepared with nylon bolts, as I did break one of the existing clips when dismantling. I also found it helpful to attach the heatsink with two bolts without the springs first, to keep it in place while I attached the other two complete with springs - I could then go back and add the springs to the first two. Thanks, Jon H.

    CPU Model is T - 2. I have a spare one if you know anyone who is looking. Purchased everything I needed - acetone, thermal paste, and the 4 nylon screws and nuts. After a few flying screws and springs, all of which were miraculously found! I managed to get the chip swapped. When reassembling the mini, I realized that I placed the heat sink in the wrong direction.

    After getting it all back in place, the mini booted up. It appears to be a bit snappier. I do not have a monitor hooked to the mini. I use Screen Sharing via my Imac to access the mini. I use the mini for home automation via Indigo and surveillance via Security Spy. It's also used for music throughout the house via Itunes. I leave those three apps running at all times so it does need all the extra muscle that the 2 Ghz chip over the 1. One thing I noticed is that the fan was spinning at high speed.

    Having swapped out the hard drive and memory, I encountered this problem before as I had forgotten about reconnecting the wire that is in the front. Only this time, I did not forget to reconnect it. Took the mini apart several times to ensure I hadn't forgotten anything. Still have the fans spinning at RPMs. Core Temps have hovered around 50 degrees C. I'm wondering if I need to remove the heat sink and essentially start over to get the fan speed and noise back to normal.

    Hoping someone can give me some good advice on this. Have had the mini running under the new chip for approx. Thanks, Lee M. On Nov. Runs fast. The hybrid drives gives it speed approaching SSD for boot and commonly used applications. I broke 2 out of the 4 fan installation clips like most people did. I used these on the reinstall. This allows you to install the other 2 with spring on. A second pair of hands is helpful to spin on the nut while one person use a flat head screw drive to push the bolt through and tension the spring.

    As others have, I used acetone to clear the old gunk off the heat sink. I used Arctic Silver AS5 paste and it has worked well. Mac mini 2,1 compatible Mavericks?!? Ahoi there, my father has an old Mac mini 2,1 from running Snow Leopard. Since As far as I could google it, the 2,1 mini is not supported although other 64 bit i.

    While visiting my parents the other day I opened up the AppStore and guess what, it told me that Mavericks was available and ready to install. Since I was in a hurry and didn't want to ruin the current system I left it as is. Is it possible to install Mavericks on the machine without any hacks or special tweaks? Thanks in advance Fabian. The reason is because of the graphics chipset. Mavericks will not run on that 2.

    That is a for sure. There are ways to get Mountain Lion running but….. Have fun ever upgrading. Lion is it for that machine and yes it's mostly the video hardware. Thought as much But the AppStore said the same thing like it said when Mavericks first came out. It just said download and install. Strange thing Since I don't want to do any funny business on my fathers Computer, is there a Way to get I just want an OS on the box that has current security updates. I would recommend upgrading to a new er machine at this point.
