OS X Yosemite Keeps Crashing To Log-In Screen

You say 10.10.2? There is no such upgrade. The latest is 10.10.1. We are hoping 10.10.2 will fix this problem, but first, Apple has to admit it IS a problem. Why aren't more users seeing this???

It was likely a typo, because he said “Here's hoping 10.10.2 fixes it” in a previous post. In any event, you’re wondering “Why aren't more users seeing this???”. This is just one discussion, and there are probably 50 distinct users in this thread. Who knows how many users this bug is affecting? It could be hundreds, or it could be thousands or more.

I realize this issue is "real;" And until there is a "real" fix, the Facebook suggestion is a band-aid that may help some users stop the logout process before losing their work. If you have any other suggestions that may HELP us solve this issue, please share; but dumping on other people's suggestions without even trying them is borderline trolling.

MIne is now running but in SAFE MODE so not fixed but useable,my brother in law got it working as he is the IT man at a local school and said they have had quite a few issues with Yosemite.

hope this helps others here..

I do have 10.10.2 (pre-release 14C68k). It's been running for over a week now and I haven't seen the problem. However, like I said earlier when I wake my machine, I can't use my mouse or keyboard. If I press a key, I hear a sound but that's it. Same result only I have to reboot which is worse. Is anyone else running 10.10.2?

10.10.2 was released to developers only. So, it is probably not ready for prime time yet. Maybe they will work out this issue prior to release. I hope!!!

Hi

I am another user with this issue too. No pattern that I can see at all. I have two accounts - One always logged in as media server and my normal user account where I spent my days. Something I noticed with Synergy is it reports that something has already bound the the address it wants to use which is weird and sort of indicates it did not kill all tasks completely during the crash.

Do we all use Little Snitch?

Just curious to know if you're dual booting your Mac? And if so, whether you're using a boot loader like rEFIt or rEFInd?

I was doing this on my MacBook Air and had the same problems not waking from sleep properly. After I uninstalled the boot loader, the problem went away.

Brand new 27 Inch mac (Non-Retina) - Crashes randomly. Fresh install to try to fix the issue did not change anything. - Used with 2 users switching

13 Inch Retina laptop - Fresh install - Never a problem - Only ever 1 user at a time.

Thinking about, I use little snitch on both. - Bang goes that theory.

Just happened to me again. This time I was launching an application (Forklift). It was the fist time I launch that application since the upgrade to Yosemite... so nothing to do with it.

Anyway, sometimes it happen at night when I am not on my Mac...

I don't have multiple accounts and no dual boot setup. But yes I do have an SSD with Trim-Enabler. But here at the office, we are 5 person with the exact same setup (hardware setup and Yosemite), and I am the only one with the problem.

The strange thing is that it didn't happen for the last 5 days before this morning!

No. I have used Little Snitch in the past, but not since Mountain Lion. So, rule that out.

Yes, most of my reboots happen when I am away and over night often. They are entirely random and have little to nothing to do with any applications. I have also experienced an immediate reboot when restarting and trying to login. This only happened once, but that is enough to suspect something is wrong with Yosemite. I have already made the decision to revert back to Mavericks if this isn't fixed (and actually listed in the fixes) in the next update (10.10.2). This is entirely unacceptable and unexpected from a company like Apple. I sincerely hope this is not a preview of things to expect.

4 Days normal use without crash, today like 5!!!! Impossible to finish the work.

I brougth the mac to the genius again they told me i would need a clean install without restoring from TM, SERIOUSLY???

SStill happening,the only way to use my Mac is in safe mode.

seems like apple couldn't give a toss about this problem as there is no fix and no one from Apple has responded.....

I last reported on 11/15/14. As with everyone else, same problem persisted.

However, I have been able to greatly reduce the frequency of occurrences.

I'm still certain that it's Yosemite's fault, but was able to trick Yosemite into not freaking out 50% of the time by adding a fan control application (http://www.macupdate.com/app/mac/23137/fan-control) and increasing the fan speeds to around 1850-2150 RPM. I did it for ODD, HDD and RAM and am not sure which of these was getting too hot.

Hope this helps some or at the very least we can all do a mass testing of this.
