Disk utility stuck on updating boot support partitions
I also found a non working 2006 1.5Ghz Core Solo that needed some TLC and would not power up.
I found a couple programs that do not run if the mini was still showing Macmini 1,1. "(from 8/5/2013 mail) Thank you for the possibility to share experience on Mac mini upgrades!
(FYI: This page covers 2006-2008 Mac Mini models with socketed CPUs.
(CPUs in 2009 and later Mac Mini models are soldered to the motherboard.) Sponsor OWC has Mac mini upgrades (ram, drives, etc.) and take-apart guide videos for 2006-2008 Minis and later models.
-Nick"(from 9/26/2013 mail) Installed a used 1.83Ghz Core 2 Duo T5600 in my wife's Mac Mini Core Solo and upgraded the RAM to 2.0GB. Today I upgraded my Mac Mini Early 2006 1.66GHz Core Duo to a used 2.16GHz Core 2 Duo T7400. I had a difficult time getting the pins out of this Mini.
The hardrive in the mini crashed and I figured it would be a good time to install the T5600 in it. My wife's Mini made me wonder why people were having problems getting the pins out. 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 10.7 on the 2.16GHz machine just to see if I can get it to work.
