I turned on my computer yesterday to have it hang after login with user A. The desktop loads but (sometimes my icons appear, sometimes they don't) but as soon as I try to do anything with my mouse, it goes circle wheel of death.
However, when I login with a user B, everything loads fine. (Of course, all the files I need are on the user A login. I barely even knew I had a second user account until I started trying to fix this as I had an auto login setup.)
I've done the disk utility repair disk and repair permissions, as well as the PRAM reset and SMC reset. Also did a "reset home folder permissions and ACLs" and the parental controls tricks per this post: One user can't open anything after Yosemite upgrade I've even uninstalled a ton of apps.
None of it helps. I've also booted into safe mode. And it's the same problem, user A hangs after log in.
I'm currently re-installing Yosemite (5 hours left, this is ruining my day).
If this doesn't fix the problem, does anyone have any other suggestions? Or if you've had this issue, how do I prevent it from happening again?
I'm using an iMac if that makes a difference.
