Hi Everyone,


Imac7,1 10.5 patched fully (OS / Security / Java /Flash ) has been working like a system should for the past few years. No reboots needed. Always on. I basically use it to watch video, play audio, nothing CPU intensive. I was Internet Connection Sharing to one netbook, but as of last week added a new Macbook Air OS X 10.7.


If not that night after buying the Air, or the day after... The Imac beachballs permanently if I'm playing video files or using the internet, and the only way to get it back is an SMC reset. Anything other than an SMC reset just gets me to the prelogin wheel spin.


I've turned off Internet Connection Sharing, switched users, ran Disk Repair (only permissions on some java folders needed fixing), tried Safe Mode, looked in the logs for obvious things, but no luck yet.


Finally got around to watching the Activity Monitor when Firefox was playing back some Flash video and I actually saw the CPU above 100. Killing the process saved me from doing another reset


Any ideas what I should try? OS upgrade? Flash downgrade?


Is there anyway to prevent applications from using that much CPU and automatically shutting it down when it does?


Also curious if verbose logins, without the SMC reset, would give me any information...


Appreciate any suggestions. Thanks Appleworld.

iMac, Mac OS X (10.5.6)
