| Hey Andy,
You’re 100% correct. While there were no notes in 10.10.2 of addressing a specific AD bug, I did hear some chatter about the beta builds helping address similar issues. Since it was beta, and since the possible fixes were here-say, I just wanted to see if there was any verification beyond that. I certainly didn’t think so, but was curious.
Since this is a public list, speaking about beta builds of OS X or iOS isn’t allowed. And my responses would echo what you’ve heard from enterprise support, so I won’t waste any time being redundant. With that being said, if you’re currently being affected by these bugs and you’ve called into AppleCare, thank you! That is the most important thing. Don’t hang up without a case number. If you’re affected and haven’t called in, you are still encouraged to do so in order to add impact. Mike and I will continue to advocate for a fix, and the current workaround from 10.10.1 is the only option at this point. We do know that this is inconvenient and doesn’t allow you to paint a clear picture for those that you support.

Corey et al.,
In my initial testing, 10.10.2 exhibits the same behavior after a force shutdown. No joy. In my limited testing, I’ve found the workaround still is effective, but it has only been effective some of the time, on occasion requiring multiple cycles of force-shutdown
and re-execution of the workaround. I’ve only been testing on a single machine, so I do not know if this behavior is common or not.
Corey, the release notes did not include any clear reference to this problem, which is likely why it is not fixed. As our “Apple Insider,” is there any clarity around where this problem sits with engineering that you can provide, or additional gentle pressure
that you can exert? As it stands, moving clients to Yosemite results in a potential increase in support staff workload that we can’t afford to expose ourselves to. With the next OS update cycle just starting, I am not optimistic we will see relief soon. I’ve
spoken with level-2 enterprise support and received the “we’re aware of the impact” and “we can’t predict when it will be fixed” and a lot of “engineering doesn’t share that information with us” comments, all of which I understand, but none of which help me
communicate with my management a resolution roadmap.
Regards,
Andy
Andy, Zach, Don and everybody else…thanks for the excellent write-ups and detail on the issue. While I’m glad that the workaround was successful as an interim solution, I’m also curious if 10.10.2 fixed the issue. When you complete any testing and have some
results, let us know.
Thanks,
Corey

I have found Chris’s suggestion works in my environment. The “fix,” however, makes for a very long boot delay. So I’ve deployed a file of a different name to all my Yosemite machines that will allow the support personnel to quickly resolve failed
boots without imposing the penalty of slow boots across the install base.
I created a script /etc/rc.server_bootfix that contains:
#!/bin/sh
/usr/sbin/BootCacheControl jettison
mv /etc/rc.server /etc/rc.server.bootfix
My instructions to my support team are:
Boot single-user (command-s)
mount –uw /
mv /etc/rc.server_bootfix /etc/rc.server
Exit
The machine boots (slowly). Subsequent boots do not run the script, so boot performance is not affected. Users that are in the habit of forcing shutdown can have the last line of the script removed and suffer long boots until 10.10.2 is released.
As for saving files as PDF’s to get around version mismatches in iWork, we long ago concluded that this was not a viable solution for students, particularly in the lower grades. That decision has caused us to scramble with each iOS release, but
that’s why we use Casper Suite to manage our OS X devices.
With 10.10.2 in developer preview, and the observation that AD/force-shutdown does not result in a boot-hang in 10.10.2, I am hopeful the release is just around the corner.
Regards,
Andy
Thank you Don! I am so grateful that you have found this article. I am embarrassed I didn't find it. Thank you for all your help and support Rockies Edu!
