OS X Yosemite Keeps Crashing To Log-In Screen

Same thing is happening regularly to me on my MacBook Pro (Mid-2012). I run some of the software that's been described in the thread, but not others, and I haven't noticed any rhyme or reason as to when the crashes happen (other than at the most inconvenient times)

Just received this from Dropbox:

"We’re reaching out to let you know about an issue in Apple’s new OS X Yosemite that causes problems with Dropbox. You can resolve this issue by installing the latest Software Update for OS X Yosemite.

OS X Yosemite may occasionally cause some programs to crash when you open, save-as, or first save a file. These crashes are rare but happen when an application, such as Dropbox, uses Yosemite’s official Finder integration — and if that program crashes because of this interaction, unsaved changes may be lost.

To fix this issue, Apple has released OS X Update 10.10.1. This update is available for free in the Mac App Store. Details on how to update your Mac are available on Apple’s support site."

Not much of a help if the issue persists after update, but thought I'd share; the Finder integration issues may explain why so many different applications seem to trigger the event ...

As a follow up to my own post earlier, re-enabling the translucency preference had no long term success.

Here's hoping 10.10.2 fixes it

Exact same problem,keeps crashing to log in screen and the thing is only a couple of months old and now cannot use the thing 😠

I reported this issue as a bug. It was closed a couple of days later as a duplicate of bug 18480104, which is still open. (Unfortunately, I cannot see that bug. Only it's status.) I'll post here if/when the status changes.

I am a relatively long time Mac user, and I have never seen this issue of crashing and kicking you back to the login screen before I upgraded to OS X Yosemite. This has happened to me a number of times since I upgraded. The only common denominator I can see here is OS X Yosemite. Operating system instability used to be the sole domain of Microsoft Windows (one of the reasons I switched). Steve Jobs would be absolutely appalled at this. Come on Apple. This is just not acceptable!

Another follow up: the newest update definitely did not resolve. Minimized Photoshop and then got the crash/login screen. Very frustrating, as I was in the middle of multiple tasks (which actually seems to be a common factor for me) ... I acknowledge this is more of a rant than a helpful post, but I, too, have been a long time advocate, and this is very disruptive to both my workflow and my confidence in new releases.

Same here - upgraded to Yosemite & randomly get booted out to the login screen, logged out. This is terrible. Late 2011 Macbook pro with a SSD in place of the DVD drive, booting from the SSD. Is everyone else booted from SSD? Just looking for *something* we all might have in common (other than just Yosemite).

Yes, I boot from SSD as well. Had no issues before upgrade to Yosemite though.

Here is my hardware:

Macmini 5,2

Intel Core i7 2.70GHz

16GB RAM

AMD Radeon HD 6630M 256MB

Samsung SSD 840 PRO 512GB (main OS boot drive)

Hitachi HTS727575A9E362 750GB (data only)

I haven't seen the issue since 10.10.2, but I think I've just been lucky going off others who say they still see it. Although for a brief period after the update, I lost keyboard and mouse after a sleep which totally sucked. It happened 5 times, then went away... If safari is up for a while, images on sites I'm at start to get mangled and flash while moving the mouse around. When the problem happened for me, it was mostly while interacting with safari and usually a little after coming back from the login screen. This release hasn't been very fun so far, at least I haven't lost data yet.

Mac Pro Late 2013

i7x6 3.5ghz

32GB RAM

AMD FirePro D500

PCI SSD

Same thing happening to me. Keeps crashing after logging-in and even while playing games (app).

I was having an I high hope that the latest 10.10.1 fill fix this, but seems like we need to wait another release.

MacBook Pro (Retina, 13-inch, Late 2013

2.6 GHz Intel Core i5

8 GB 1600 MHz DDR3

500 GB SSD

I'm having same issues.

My mac restarted now 6 times in 10 minutes.

I have Yosemite 10.10.1,

Macbook pro 13-inch, Early 2011

SSD Drive (replaced over year ago)

4GB 1333 MHz DDR3

2.3Ghz Core i5

My laptop is basically unusable right now, no idea what to do...

Yea, I'm having the same issue. It seems to happen when the machine is under heavy load (Chrome with a lot of tabs, Photoshop and/or Illustrator, and Spotify, etc) running...

I have an i7 Quad Core processor with 16GB of RAM. That should be more than enough to run Chrome with a dozen or so tabs open. Granted there are quite a few other background processes running like Dropbox, etc., but I've had it under heavier loads running VMware with no problems. This is definitely some sort of bug with Yosemite. I never had this issue before I upgraded. Really hope Apple can figure this one one soon. Murphy's law says it will always crash at the most inopportune time, and it does!

😠

Mine is never under any load,I log in then after about ten secs it crashes back to the log in screen.

Really getting fed up with this now over a grands worth sat on my desk doing sod all just collecting dust and am now tempted to dig out the windows pile of crap this thing replaced at least that works.......
