I've dragged and dropped the installer from the App store into our JSS, created a policy to cache the package, and created a self-service policy to run the cached install. what im finding is that the machine runs the install, and then upon boot, freezes with 50% on the status bar. I've even gone ahead and restarted and tried to install from the recovery mode, and the machine still no longer boots. this has happened on the 3 machines that i've used to test.
has anyone else experienced anything like this? kind of freaking out, because after successfully running the installer on a couple machines, i went ahead and tested on an "eager" user, and now his machine is inoperable.
it's happened on various machines, 15" Retina macbook pro, 13" macbook air, and a 15" 2011 macbook pro (that i had laying around to test with) I've tried decrypting the drive from recovery mode, and it's still booting 50% and then will not boot any further.
I have seen the same issue. About half of the time resetting the PRAM resolves. The other times, I have to remove the user from FileVault, reboot and then re-add them. Happens on about 10% of our machines only after upgrading from OS X Mavericks to OS X Yosemite.
hey Emily, i did try to boot in verbose (and single user) and the error i see is "register_decmpfs_decompressor 0: CMP_Type7 failed: 17" -- unfortunately the only information that comes up when i look for people having that same error are hackintoshes, and a chinese page i translated that basically said "formatting and re-installing fixed it."
looks like im basically screwed, I followed the process to a 't' but it simply did not work as it was supposed to. I've managed to move the user accounts and re-installed/manually migrated and i've got a working laptop again.... i'll have to do that with the rest as well.
We're suddenly seeing this same issue on just about every Mac here that's attempting to upgrade. Had over 80 macs successfully upgrade with no issue up to now and in the last two days we've seen three macbooks who attempted to upgrade experience this.
We tried the cache purge with no success.
Can someone confirm that if you decrypt prior to upgrade this problem will not appear on reboot and a subsequent reencrypt succeeds with normal boot afterwards?
I had to help someone who had this happen to them while off-prem… I had him boot into the Recovery HD and turn off Wifi, then reboot and it eventually logged him in.
Might want to try upgrading to 10.10.3 once you get the machine to boot to see if the update fixes the issue.
I'm having these issues on 10.10.5. So far it's happened on an iMac and a MacBook Pro retina.
One issue I see is this:
dyld: Library not loaded: /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/vecLib
Other times, its
pci pause: SDXC
The fixes I've tried are, PRAM, SMC, removing Bootcache, fixing permissions, all the things I've found while searching DDG and Jamfnation.
I'm seriously at a loss. The topic died down after a while so I'm curious what fixes actually worked for people.
Fixes I tried:
