Q: mac pro 2009 freezing
My dad's mac pro 2009 running os x 10.11.4 is recently been freezing when i am doing simple tasks such as safari or word. All of the sudden, when i searching google or working on a document, the mouse freezes and the keyboard no longer responds. The computer is frozen for a couple seconds before restarting. I get the message would you like to open the applications that you had open before the crash, but today i got a kernel panic report. Why is it crashing all of the sudden. The mac crashes maybe one to two times a day. My dad has macs fan control running, which i think may be an issue because console said it was excessively waking up and it was invoking spin dumps. This report, which i got today, mentions CPUPowerManagement, does this have anything to do with the fans or is it something completely different? What can i do to stop these freezings from happening?
Thanks.
