MacBook Pro (2007) 3,1 & 10.8.5 freezing
While it goes without saying, firstly if you possess one of these MacBooks (I believe the unofficial model description of these MacBooks is the "Santa Rosa" model), do yourself a HUGE favor and make a back-up before attempting to upgrade to OS X 10.8.5.
Regarding my expereinces thus far attemtping to update:
At the onset, I can attest to the fact that my MacBook Pro runs OS X 10.8.4 flawlessly. Furthermore, the Apple Service Diagnostic disc for my 2007 MacBook Pro 15'' 3,1 Intel Core 2 Duo 2.2GHz A1226 MA895LL/A reports absolutely NO Hardware issues whatsoever including the memory check. I have tried EVERYTHING in performing ALL the obvious troubleshooting (i.e. permissions repair, SMC & PRAM rest, subtracting/adding memory modules etc.).
I have also installed OS X 10.8.5 in all three (3) possible configurations (software update, combo update and the full/clean Mountain Lion OS X 10.8.5 .app install) and all have produced the same result with the system freezing. The vast majority of times after a successful install, it will freeze right at boot up (i.e. white screen, grey apple, and spinning wheel) though several times I have actually gotten to both the login stage as well as in the desktop itself before it freezes. I have tried installing it both on internal and external hard drives yet it makes no difference. I am at a complete and utter loss as to what the heck to do. I have owned a mac of some sort since 1998 and I have never experienced a situation regarding an incremental OS update like this ever before.
