Mac Pro - equally thrashed
Hi - new to the forum. Had to register to post my own woes. Mac Pro 2.4 dual quad-core 2010, updated through software update (how, in all these years, did I miss that that is not smart to do??), then she'd hang on startup, during the spinning wheel under the grey Apple. Dozens of times. Tried clearing PRAM, safe booting, etc. Nuthin. Rebooted from Techtools eDrive, ran diagnostics, repaired permissions/rebuilt volume, etc. Nope.
So now I'm in the midst of installing Mountain Lion - leaving Lion altogether in the hopes it will paste over the problem. OK so far, it's installing with no dramas. Couldn't do a clean install as it's been over a week since last backup and I've been busy at the keyboard.
Wish me luck! I'll post with results. Sorry for all y'all having similar issues. SO frustrating!
Cheers...
