I have the same issue: mid-2010 MacBook Pro 15 inch (MacBook Pro 6,2) and this article describes an issue I am having:
I checked my firmware version via system profiler:
- Boot ROM Version MBP61.0057.B0C
- SMC Version 1.58f16
- OS Version Mac OS X 10.6.8 (10K549)
The list of firmware updates (http://support.apple.com/kb/HT1237) says I need:
This link (http://support.apple.com/kb/DL1492) in turn says it is for the right hardware (mid-2010 models), but only support OSX Lion.
The advice provided by Mr. Davis did not work in my case. Clearly, based on comparing System Profiler to published articles, there are both EFI and SMC updates available for my system newer than what I have, but Software Update fails to find any available updates.
Further, the articles referenced above specifically mention firmware updates may not be covered under Software Update tool.
So, that brings me back to square 1, I have an issue with hangs and the OS going off into the nether world for up to an hour at times, there are published solutions specific to my hardware for a very similar issue, but the links to the patches result in files which cannot be applied.
Any help will be greatly appreciated.
No answers online, so I went to the Mac store. There was an issue with my harddrive. After a new harddrive, restore from Time Machine (wow...that was easy), at OSX 10.6.8 the firmware updates (1.9 or 2.1 or 2.6) for this model cannot be applied.
Upgraded to Mountain Lion (10.8.1 - very easy, no issues), and then software updates found the firmware update and now it is updated to BOF.
The SMC firmware still shows up as 1.58...
I always ran updates as they were available, so I am wondering how I was in a OSX sub-version incompatible with multiple firmware updates? Oh well...fixed now.
