Yosemite gets frozen at login screen

[mrbojangles]

i upgraded to the NEW Yosemite yesterday on my macbook pro for curiosity, i ran pretty normally yesterday. But it got frozen at login screen when I started it up. I tried every comands i could find, but none of them worked. Please help!

----------

I just couldn't work with my laptop, and such a problem really made me disppointed at Apple. I will never upgrade a beta OS again. It's a huge mistake.

Try to click around a little bit. I held down the power key and it pulled up a menu which provoked my curiousity to click around a little more.

Click the top left corner, see what happens. Press cmd+space to pull up the spotlight, just start pressing buttons and you may get back your desktop

The cursor is not frozen, but it turned to be a spinning wheel after I clicked the user name, or even Guest, which doesn't need a pw. The screen just stays there for long time. The bigger problem is that I failed to back up my data. Now I realized it was too risky to upgrade the beta on my whole hard drive. You did a great choice to install in just on a partition.

Anyone who has the same problem?

I'm having the exact at problem. It seems to have installed alright but on the login screen I type my password and it's stuck with the curse on spinning wheels.. Driving me crazy from the past 3 days anyone solved it yet. Tried all the options given out by you guys on here.. Safe mode doesn't work, cmd opt p r doesn't work.. Noting does., helpppppp plsssss

I'm having identical stuck-on-login issues. Mine started while using hotel wifi access and letting the MBPr go to sleep. It wouldn't wake up. Then on reboot it would stick on spinning or beach ball at login.

To fix.....I left hotel and went to a restaurant location where I'd previously used their wifi. Booted right up.

I think it's something to do with getting stuck on Wifi access and/or iCloud login.

When I saw the spinning wheel, I knew the OS was trying to get out of those possible "one million" threads or something. I was the unlucky one that it failed. Actually I didn't regard myself as a professional when i tried the NEW OS. It is "frustrating" to a general MAC user, which Yosemite is not designed for unfortunately.

Anyway, I've already solved the issue and I'm enjoying the old Mavericks back again now.

lol this is one of the more amazing dialogues I've read on mac-forums. 'which Yosemite is not designed for unforuntuately' is my fav part.

The issue is still happening now in Feb 2016, except so far a reboot has fixed it. A reboot is pretty onerous once you use parallels and Windows and have lots of things opened
