I am ready to dump mountain lion and go back to snow leopard

Greetings Eric, this is a nice compilation and thank you for your effort. I will look at each item for applicability I have to tell you I am not new to these problems and have been doing the maintenace on the manchines for a long time. I often use these tactics to resolve problems. Your effort is not lost on me. It is jsut that I have done most all of these solutions over the last two years. Some work and some items would help for a while, then come back. I'll give it a go and let you know. Thanks for your support.

Linc, I know this is more of a plea for help then an actual question. Thanks for your patience. I have read and followed your help with many other problems I have incurred over the last could of years. As you answer the some message thread from others that have been having similar. I'll start with the first item which is the kernel panics and go from there.

I would challenge your notion that these problems are not typical. On second thought you might jhave to define typical.

I know the problems I have faced are prolifically documented throughout this site and others. A few people in the threads get some relief but most users keep the hopeful phrase " Maybe in the next version". I am just tiered of serching endlessly for solutions to incomplete and sometmes broken OS X items, only to repeat the search for another mac or macbook.

Yesterday, I even had one user who could not print to a USB HP P1006 printer. Really...

Onxy is my friend too.

Matthew, I agree that beta is no place for production. I have had to use the beta as the Nvidia drivers in 10.8.2 were vere problematic on that machine, which a has Nvidia 9400m Video card. I have a dev license and know when there have been certain changes in the OS build. So in this case it has helped. Apple has just seeded 10.8.3 12D68 and it has many video updates that make the graphics at least usable. I really pity the ones with ATI cards...

So, That machine is going to stay 10.8.3 or I'll rebuild in back to Snow Leopard. I would not have much choice but to rebuild it, even if I were to roll back to 10.8.2.

Thanks for your patience too.

I'll start to post the ssues in ther posts as this could confuse others looking for solutions to specific problems.

I have not applied SMC firware Update 1.7. Have you applied it? Maybe I should.

On a another discussion I started Linc Davis suggested I uninstall Boom (sound volume amplifier software) to see if that helps. I have done so on one machine and the others to follow. I may reinstall it to see if the problems come back or if it is the fact I moved on to a different version of Mountain Lion and did not install it again.

Uninstalling Boom on the 2011 13" MBP has not helped it with Kernel panics. So I have no solution for these problems, yet.

I would agree with you on some of my other machines which were migrated. But this is also happening on a new 2011 MBP built from scratch on ML 10.8.2. New machine, new user, new OS, no migration. The only move made from another directory was an import of outlook.pst through Outlook for Mac 2011, and a directory of My documents from a NAS into Documents. That is all.

dear dwb, Thank you for your suggestion. I have not conducted a long hardware test. I think that is a good idea. I will say now that 10.8.3 is installed it is running much better. I am stressing it now and will find time to conduct a long hardware test. I may use Alt +D to login to an internet boot to run the test. Will report back, thanks for your help!
