MacPro Early 2008 _ Freezing
Please help…I have a MacPro Early 2008. I am running Mac OS X Lion 10.7.5.
Processor 2 x 2.8 GHz Quad-Core Intel Xeon
Memory 8 GB 800 MHz DDR2 FB-DIMM
Graphics ATI Radeon HD 2600 XT 256 MB
The issue that I am having is this: my Mac freezes up off and on throughout the day. It seems to happen after I have been on the internet, especially if I use FireFox, (43.0.4) and download anything. I have downloaded fonts, Photoshop backgrounds, brushes, stock photos, etc.
I had two things happen that may have caused this:
) I was trying some pdf compression software through the internet, and it would crash my system after a few compressions.
2.) The battery backup on my Mac failed a couple of times and brought my Mac completely down. It is a professional sized unit, so I am assuming something is wrong with it.
Before my Mac freezes, Illustrator starts responding very slowly. Eventually, it locks up and I am forced to do a hard shutdown at the CPU. Sometimes my monitors (dual cinema) will shut down as well.
Once I reboot the Mac, then Creative Cloud will launch and ask me to sign in even though I did not have it running before the crash. Typically the crash will also cause Suitcase Fusion 4 to fail, and I have to rebuild the FM Core.
Someone suggested that I buy Bitdefender and see if I picked up some malware. I haven’t done that as of yet. I don’t run any security software other than keeping my Mac security updated through Software Updates.
I am hoping someone has some ideas about what might be causing these issues, what I can try and how to resolve the problems.
Thanks so much!
