I have the same problem, though it happens just with mail open. I'm running a mac pro with a 500 GM solid state drive, 6-cors Intel Xenon, 3.06 Ghz, 32 GM RAM. THere's no way I should run out of memory with just word, mail, and calendar open!
This has happened 5 or 6 times since installing Yosemite last week.
Very disappointed with Apple. A costly and irritating error.
Other issues I continue to experience with Yosemite:
- MS word opens read-only files, obviating changes. Need to open each file twice.
- OS fails to recognize shared Mac Air drive, where all my office's files are located. Connecting to it is troublesome. And even when connected, applications are unable to save to that location as it fails to show as connected in the save dialogue box (unless the application is defaulting to that folder).
- cannot post online into text fields without the browser (safari) flashing and fidgeting uncontrollably, can no longer see what's being typed, cannot delete or make changes. I thought this might be a result of a java update (I had a message that I could not run Illustrator with Yosemite without updating java. So I reinstalled yosemite, took out the java. Cannot run Illustrator, but the web post problem still persists).
Can anyone fix these problems? How do I get rid of Yosemite? Can I just go back to Mavericks (which was still pretty buggy, but nowhere near as bad)?
Should I just sell this computer, and go back to PC?
