    Anyone else that has this problem? The progress bar gets stuck in the middle and nothing happens for like 30 minutes then the screen just turns black. Yes, i know its a developer preview, but i have been able to boot before and if it is a preview i should at least be able to boot it up. right?

    Try a fresh install, then restore your data. If you updated it can cause pretty weird issues, this looks like one of them. A fresh install usually fixes 90% of weird glitches that aren't documented

    Try booting in verbose mode to see if it's one particular thing that's causing the delay during boot. Hold Command-v during boot to see the white text.

    Just for interests sake, why does updating cause all these weird problems? :confused:

    Updating is sometimes like putting a band-aid on a severed leg. May feel like it's doing something helpful but it really isn't. Doing a fresh install will get rid of problematic files that may be lurking about.

    Had same issue last night. I just held down power till it shut back off while it was stuck. Hit power again and everything booted normal.

    I have a fresh install of 10.10 beta 1 and then have upgraded to beta 3. I will try verbose next time. Thanks for the suggestion

    I'm having the same problem. Installed over Mavericks on a 2012 iMac and when it booted up, I couldn't see the taskbar or dock. After rebooting into safe mode (well, trying to, anyway) it's frozen as the OP described.

    This is just great.

    Run SMART Utility to make sure your hard drive isn't failing. If it passes, run a disk verify/repair.

    I did a verbose boot; it seemed to be hanging on rebuilding kernelcache or some such - anyway once it got through that it all went back to normal. YMMV
