Going to the Apple Store is fading for optimism. I've run the Apple hardware diagnostics and there's simply nothing wrong with the machine. Yosemite 10.10.3 has got a massive problem. Here's the beauty part:
A virgin copy of Yosemite 10.10.1 was downloaded from Apple and then started such that it would install on an empty disk. The installation goes part way and then boots into Yosemite to complete the install. Note: it's booting into the virgin copy. Any software I have anywhere else is irrelevant at that point.
In five tries on two different disks, the installation failed with the same black screen symptom I have seen previously. The only recovery is unplug, wait for SMC to reset, and boot.
Previously I had installed Yosemite on the iMac's SSD so I know the installation has worked before. There is no explanation I can find for why it fails now.
Some consistent things I notice about it:
Every time it sleeps it will crash
Every time a complex video is edited it will crash
Other crashes take place randomly with no apparent provocation
Software notes:
Adobe Flash Player is removed and burned
Virus scanners or memory cleaners have been removed.
Net change from that: zero
Running out of debug options as it's $29 just to talk to Apple about it.
(This is not a plea for money. If you want to help, buy a CD ... please. That won't result in anything for months but it's better than being a charity case.)
Fiendish plan that could conceivably work:
Download the virgin copy of Yosemite to the laptop. Install it to one of the iMac disks from there. Bring the disk back over to the iMac, assuming the install didn't die just as it did on the iMac, and boot into that virgin system. Install nothing but Final Cut 10.2, no other third-party software, etc. Test again with video. If it again fails then there's no question. The software release is the culprit as no other software would be running and no historical information would have been carried forward.
Brutally disheartening as video is stabbed in the heart and the regulars have seen how important it has been. So ... that's a plan of attack with a marginal chance of success and at a sure plan for diagnostics. If the installation fails from the laptop which has no reliability problems then it's a stinky install. Yosemite 10.10.3 was never installed on the laptop.
That means going offline for some while. I will get something online in time for Chicagosax later as I do not plan on missing it but lately my plans haven't exactly been playing according to the conductor's direction.
