memory?
I am wondering whether the people with problems have the max memory in their computers.
I can tell you that since I took my early 2009 17 inch MBP up to 8GB RAM, then installed SL (a totally clean install where I wiped the drive, installed Leopard clean, then SL), I have had no problems outside of user error. I was skeptical, but with a backup volume partition and a Time Machine with all original specs and applications, it was worth a try. I am glad I did. This was just this past weekend.
What launched me into it was an external drive that was not mounting for several minutes, then I discovered OS X was trying to repair the volume, but could not; so since it was the backup drive, I just had to wipe it, test it, and move on. Tech Tool Pro did the job nicely and the volume must have been repaired during a volume check since no problems where IDd. The other drive that never has shown any problems had some major volume problems, so I will have to wipe that drive tonight and restore from the backup drive.
Anyway, while running the tests from TechTool, which has a scan utility checking all sectors and on a 1.5 TB drive, that takes 4 hours, my MBP was rebooting by itself after only 45 minutes, everytime. This only happened when the machine was left alone. I found that using those "clean up" programs on Leopard must make it unstable since I have the same cleanup programs on a Tiger iMac and no problems leaving that bugger alone all night.
Anyway, since the instability was there, I figured I would upgrade the OS to SL simultaneously with doing the drive maintenance. I am glad I did and I left the computers on all night to update my Time Machine backup and it didn't reboot at all by itself. Success! I will never install those "cleaning programs" again for they do delete items needed by the OS.
Round and round...
Anyway, I am glad I got SL.
