If you plan on cloning your old hard drive onto the new one as I did then I recommend getting a firewire compatible caddy, as Snow Leopard doesn't always work with USB caddys when you try and format them for some reason - this problem held me up. All in all, a very worthwhile exercise.

I like my Mini so much I have bought a second one! This one is a and will also be upgraded - T 2. Many thanks for your site, I found it helpful. Good luck to all those who want to get the best out of their machines. I had the external drive partitioned into 3 partitions. Partition 1 was used to install This partition was then updated to I did not install Partition 2 was used to create another install of This was mainly for backup purposes in case I messed something up and could not get Partition 3 was used to install This partition was then used to create a disk image that would then be cloned onto the mini's hard drive without the platformsupport.

When it came time to install copy My original install of After the image was restored to the new partition, I rebooted my mini holding down the option key to selected the new Lion partition. It booted up and I was greeted with the account setup screen. Since this worked, I went ahead and installed the This updated restored the platformsupport.

I am happy to say my mini booted up just fine and Only complaint so far is the lack of scroll arrows in Lion. I also found a non working 1. Turns out it had been opened up several times before and had hardware that was not seated correctly. Since I had an extra 1. Replacing the CPU was fairly quick as this was my third time doing this type of upgrade. The pins released easily Unlike my 1. I had a broken macbook with 2GB of memory laying around and installed it in this mini. Got everything put back together and pressed the power button. Got what I was hoping for, a startup chime and the display showed a folder with a question mark in it.

I then used the external drive to boot the mini with Installed the Core 2 Duo T 2. The hardrive in the mini crashed and I figured it would be a good time to install the T in it. Was able to remove the pins easily and reuse them. Had a fun time doing the upgrade. Today I upgraded my Mac Mini Early 1. This mini was already upgraded to 2. I had a difficult time getting the pins out of this Mini.

My wife's Mini made me wonder why people were having problems getting the pins out. Well, my Mini let me know. Took 10 minutes to get one pin out as one side kept expanding when I tried to push the pin through the CPU hole. I plan to install I did upgrade the firmware so the machines are identified as Macmini 2,1. I found a couple programs that do not run if the mini was still showing Macmini 1,1.

Thank you for all the great information. As to Lion, it's hard to find a second Mac here to upgrade to it. On dismantlement of the CPU heat sink, I broke one of the plastic pins. They're probably not designed to be used multiple times anyway. As plastic screws are very hard to find here, I used mm-long M3 metal screws instead.

To prevent short circuits on the back side of the PCB, I put the heads of the screws through washers made of thick paper, taken from old light switch covers and AC power plugs. Or Nylon washers. Hardware Stores usually have them, as well as nylon screws. Turning the nuts on the top side of the heat sink, I adjusted the length and hence the tension of the springs to be about the same as if the original pins were used. The thermal compound I applied was Arctic MX The CPU temperature after the upgrade is several degrees Celsius higher than before it, but this may be normal as the new CPU is more powerful.

The temperature can be lowered by the so-called "undervolting". But it turned out that there are replacement pins not the same as the original ones but very close made by RichCo and called "HSR-2" which stands for Heat Sink Rivets, model 2 - you can see the HSR-2 drawing available from there. Update: as of page 'd, so link removed. They're sold by Digi-Key: www. I think that it may be useful to others. Best regards, Luchezar G. Granted may be a longshot with the way things are going to find these at stores like Radio Shack, but if you still have the spring, I've seen a selection of plastic retaining pins at some hardware stores.

Had no firewire lead to do target mode so created a partition on a mountain lion MBP, installed lion and used Carbon Copy Cloner to copy to new partition on the mini via usb. Navigated to Lion partition from SL and deleted platformsupport. Used MLPostFactor 0. All runs great apart from no internal sound, but using external audio interface so no problem.

Thanks for all previous posts. I've not used MLion much. Main work mac has T 2. Thanks to your site I made the leap and did the upgrade s. Also, I used artic paste between the chip and the heat sink. I called up the seller after googling the shop name and negotiated it for a slight discount over the buy it now price. I simply used Carbon Copy Cloner and cloned the old drive, tested it in my mac 2. As a bonus, I have the 80 GB drive as an offsite, encrypted backup for can't lose docs and pics. I had no idea how expensive the RAM was for mhz now.

About this product

It was an easy swap. It would have taken less but one of the pins holding the heat sink to the cpu popped when I installed it. I spent at least 30 minutes looking for it on the floor. I finally found it on top of the curtains! My skill set is novice at best but I considered the ifixit guides clear enough to make this possible for anyone who cut their teeth on legos.

This thing works fine, though the fan turns on when I am pushing it - think transcoding to and video for Plex - but has taken all I have given it. It currently acts as the media server and main computer for our kids. This has given a new lease to the old mac. When my wife gets some replacement software we intend to upgrade from Snow Leopard to Lion on this machine.

Been using it with lion because I wanted icloud and back to my Mac to function, which has been great because I can control it from anywhere. Couldnt do this with snow leopard since mobileme went away. I use it as a central iTunes home share, time machine backups for other wifi connected laptops, and file server I can access from outside the home. It runs headless andi use screen sharing to control it from any Mac I use anywhere. I had some difficulties with the nylon pins, I broke two of them and had to sacrifice one from the other heat sink to get the job done.

That seems to work out just fine though I installed termprature monitor just in case. I rarely hit above 70 degrees unless I'm doing something really intensive and then smcFanControl at max keeps it down. I am still running All I really needed was icloud so there's no big reason for me to upgrade although the reports of people upgrading and successfully removing the plist are giving me some confidence to do it anyway. It started with a CoreDuo 1. I managed to break one of the plastic heat-sink standoff pins but ended up just replacing all four of them with 1" steel socket head cap screws that I had lying around.

I put the screw up through the motherboard and used a nut to tighten each spring down to approx the same tension as the standoff pins. This doesn't appear to short anything out, as long as your screw head is not too wide. I guess it might be conducting some more heat to the motherboard than the plastic version, but TemperatureMonitor readings all seem fine. Anyway, so far so good, it gets a GeekBench score of about compared to originally. I've also just done the firmware update from 1,1 to 2,1 which was painless. I've ordered 2x2Gb memory to replace the 2x1Gb that I've got in there now, so that should help on the performance side as well.

I'm stuck on the Lion upgrade process - I haven't had any success in getting Lion installation media from Apple they keep redirecting me to other things , and seems very expensive to buy USB installer keys on eBay - why?? If anyone has any hints, please let me know! OS X Patrick later wrote "A brief update - memory upgrade seemed to make a marginal improvement to GeekBench score now about The MBP auto-reboots during the install and when it's done just reboot again into its normal startup disk but leave Mini in Target Disk mode to delete the single PlatformSupport.

I was slightly worried since some reports suggested you needed to mess around with parts of the installer package as well but maybe that's just to get the Mini to run the installer. Anyway, all working fine and all existing files preserved even after a software update though not one requiring a restart. It went from a T 1. With only 2 GB of ram, using the mini as a simple media center, I did not see any need for upgrading the firmware, for the 3 GB vs 2GB memory management.

Regarding the hardware upgrade, I cannot stress enough hom fragile those nylon pins that hold down the heat sink are. I broke one and had to improvise, since in Brussels, on a Sunday, you will find absolutely nothing opened to buy parts. The cpu replacement is part of an "Overhaul" on this mac; in a few hours it will most likely have I am installing My Mac OS is version I am not very sure how it will behave, regarding the plist files.

We shall see. Workarounds used were either deleting the plist file or editing it for the unsupported mini model ID. Thank you for the comphensive guide. Personally if I had an 06 Mini I'd stay with However I would still want all the ram support possible especially with later OS's although there's always some risk with firmware updates.

Installing the firmware update was a piece of cake.

Connected the mini to my Imac and loaded the Mini into Target Mode. I had purchased Lion from the app store when it came out. So all I needed to do was go back to the app store and download it again for free. A very easy and simple install. Took about 2 hours to migrate my user info from my Mini's Snow Leopard partition to my new Lion partition. I have I plan on bumping the Ram to 4 GB and my mini will continue running my home automation setup.

I had already opened the case and removed the internal frame before so those operations were not new neither is the look of my mini's underside ;-. The Logic Board removal was straightforward as well and I managed to pinch the plastic screws just enough to squeeze them through the board keeping them intact for reassembly. Swapping the 1. I scraped the thermal compound off the heatsink with a small blade and cleaned it with alcohol.

Re-assembly was easy but the mini would not even switch on thereafter. Fearing I had bricked it took me at least half an hour of scrutinising all parts, disassembing and re-assembling to realise that the failure to boot up was not due to any faults or omissions during reassembly but rather caused by one of the power button wires ripped from the small circuit board behind the button. As I did not come up with any other way of accessing the solder points I bent the metal RF shield away from the back side of the bottom housing just far enough to be able to solder the cable back on.

The metal screen seems to be "fused" to the rear part of the computer by small plastic studs that break when the screen is pulled off. The firmware update worked but I had to press the power button until the progress bar started to appear just waiting for the flashing light wasn't long enough.

I briefly considered an SSD but then went for a plain vanilla drive left over from a Macbook upgrade. Had to change the permissions on the CoreServices parent folder to be able to save, though. After another successful boot it was time to run a Software Update and migrate the data from the old Imac. This took ages via USB. No long-term experiences yet, of course. Thanks for providing step-by-step instructions!

Regards, Siegfried L. Mini booted up without any problem. Replaced thermal pad on bottom housing with Thermagon series, T-Flex boron nitride in silicone elastomer. Upgraded Mini was on for over 1 hour with no issues. Did not upgrade firmware due to not familiar with process. Guide on Mini 1,1 to 2,1 EFI linked above.

Mini runs much quicker, probably explore firmware update later as no need for installing Lion. Unless apple revised something? Or differences in SU vs Delta or combo? Normally reinstalling a combo update is the old tip for update problems at least with supported macs. Perhaps some other mini owners that reported Question - tried zapping the pram?

Update: Here's a later follow-up from Pete: "I managed to get this working I re-applied the combo update and removed the plist file and it still didn't work, so as a last resort I started in safe boot mode and it booted. I've since rebooted a couple of times to make sure everything is still functioning. So, it would seem that the safe boot did the trick that said, at some point in the process I also reset pram and reset the smc on the mini too.

I let OS X apply the I assume this is because PlatformSupport. I'll do some tinkering over the weekend and let you know what I find out. I borrowed a spare Mac to recreate the I don't know why it wouldn't boot from USB earlier. Sure enough, I deleted it, just like before, and this time I'm at a loss to explain why it worked tonight but not last night. Here's my config: Original Config: Macmini1,1 1. This is most puzzling, because the plist has been removed. I've also tried reinstating an edited plist with the model in there to no avail. I'm considering restoring back to First, Thanks for the website.

Its an amazing resource and I make a point to visit it daily. I have a early Mac Mini that was showing its age. CPU swap was easy thanks to your upgrade guide. Luckily I also picked up a set of the Nylon bolts from the local hardware store prior to the upgrade. I did break one of the heat sink mounts. Then connected the drive to my Macbook Pro via firewire and installed Lion directly to it. While connected I also applied all updates, installed iLife '11 and Office The Mac Mini booted right up after a brief question mark.

The system boots in about 17 seconds and applications launch in less than two doc bounces. Scrolling in iTunes and websites are smooth. Right now I have 2gb of ram in the computer but I'm going to pick up some more memory and try to upgrade the system EFI firmware to version 2,1. My Macbook Pro is running Mountain Lion.

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 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. Fan is loud, has less then a 10 second boot to desktop, seems to be running good. Might heat be an issue? 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. System memory map related I assume. Older posts years ago and mac upgrade vendors have also listed that limitation.

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.

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. 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. 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. 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.

I've not installed Lion on anything of mine yet. Not anything I really needed in BTW: 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.
