Hi, my iMac 27" 2011 have some kernel panic problems.
I don't know if they are linked to the last software upgrade but is very annoying....
In past I had some kernel panic but with software upgrade they disappeared, now I have same problems like in past.
Sometimes during work the screen go gray with the reboot message, sometimes when I leave and put the Mac in stop mode I found it in on with the screen completely off and I have to hold power button to turn off and then on again.
When MacOS reboots it give me the message that system has a problem.
In logs the message is Attempting to retain a freed object"@/SourceCache/xnu/xnu-1699.32.7/libkern/c++/OSObject.cpp:148

What is concerning this message?
I was a PC user, I love Mac but I cannot say that they are free from problems because I'm experience a lot of kernel panics.

P.S. I tested hard disk and ram and they are working fine.

Thank you to all that help me.
