My MB Pro mid 2012 is crashing since already some time quite often. ~2 years ago I put in 16GB Ram and a Samsung Evo SSD, no problems after that. Just recently those "crashes" started to appear.
What happens is that the current window freezes and then it seems like a chain reaction freezing everything else. I can open the force quit window and applications do close when force quit, if I relaunch Finder, the dock (and finder?) seems not to work (frozen dock in weird position). No Finder appears again in the force quit window.
The system temperature is then increasing quite rapidly and I have to turn off the MB by holding down the start button.
So, yesterday I reinstalled ElCapitan. Since then everything was fine. But now it just happened again.
I am worried that the computer is being damaged, and also since it's annoying I would like to figure this out for good.
It seems not to be the Safari problem that was in the news recently since my MB is older and the newest ELCapitan update is installed. I also ran chrome and I still had crashes (before reinstall).
Can you please let me know how to proceed?
Under Console I have a lot of files, including 4 crash reporter files from: com.apple.networking.eapol.log.20160623T225508-04.gz
and 2 diagnostic reports from backupd and Clean my Mac 3.
Please let me know how to proceed, I would appreciate your help a lot.
