Macpro 2013 late update 10.10.2 make problem with thunderbolt drive

This is very strange. I bought mine from LaCie direct since we have no Apple Store in Iceland. Jettison is a great utility. It ejects external when my mac goes to sleep and mounts when I wake my computer . There are many other settings, ejects before shut down et cetera. It made by St. Claire who makes Default Folder. I like this little utility a lot.

Thanks.

I don't think it will solve our problem, because the crash happens only when turning the power off from the drive unit, and this is done after the unmount.

I have clearly misunderstood the issue. Naming Jettison was not meant as problem solving. Well I might have this issue as well. But I never power off my externals just let Jettison eject them and put them to sleep when my computer goes into sleep. I am not eager to find out if I have this issue.😕 Thank you for clarifying Pito.

I have the same problem with an external disk G-Technology via Thunderbolt.

I think I've « solved » the problem proceeding this way :

- I eject the external disk

- I put my computer to sleep

- when my computer is asleep, I turn the power off from the external drive

- my computer awakes (and goes back into sleep after about 20 seconds if I do nothing) but no panic !

NB Sorry for my bad english...

That did not work here. Kernel panic again. The only thing that works is ejecting the drive, putting it to sleep, then putting the mac to sleep or shutting down the mac. After having put the mac to sleep and waking it up again the sleeping drive will not be woken up, it will be put back on the desktop after a previous mac shut down and restart. Both without any problem so far.

Is it really the same problem ?

Mine was the following one : when I turned the power off from my external drive (after ejecting it), my iMac (27 inches mid-2011 Yosemite 10.10.2) crashed and rebooted.

Now, if I put my computer to sleep just before turning the power off from my external drive, the problem is solved.

I did it 6 times to be sure and everything's OK.

Same issue here, imac 2014 and LaCie d2 TB2.

The sleep solution didn't work for me neither.

But no trouble with a LaCie 2big TB2 (bought at same time, same place).

I confirm that, if the same drive is connected via USB 3, my MacBook doesn't reboot. So it is definetly a Thunderbolt problem introduced with the update to 10.10.2

My drive is a LaCie d2 3 TB Thunderbolt/USB.

Same problem here. 2014 Mac Pro, 10.10.2, with OWC ThunderBay 4, 4HDs as software RAID 5. Computer reboots when I power off the drive after unmounting drive. Apple won't help despite Applecare valid through 2017 because it's a RAID. Problem started with 10.10.2 install.

Also experiencing after 10.10.2 update: G-Drive with Thunderbolt attached to 2013 iMac.

I talked to AppleCare this morning at length and they want me to bring everything to a Genius Bar to look into it further.

Drive seems to work perfectly with the USB cable. Luckily it has the option for now.

I am having the same issue here. I was about to shut down my Mac Pro...ejected the La CIe TB2 drive, then powered it off...then a second or two later my display screen went black. The Mac Pro did reboot automatically and I checked the Console app and confirmed it was a kernel panic. Because the La Cie TB2 drive has been working well with previous versions of Yosemite, I can't help but think this issue lies at Apple's doorstep with OS X 10.10.2 update. Trying to figure out now how to send them my crash report from the Console app.

Noticed the problematic LaCie drives are not recognized by LaCie Desktop Utility anymore.

I wonder, has someone tried the Apple thunderbolt cables yet? Normally we would just use the cables provided by the drive manufacturer.

The Apple cables are quite expensive but may be a tiny bit different, maybe better.

Well, this discussion has been quite useful with my setup.

It seems that I also began having unwanted late 2013 MacPro crashes and restarts after upgrading from OS 10.10.1 to 10.10.2.

The restarts occur when my automatic programmable power timer shuts off my OWC Thunderbay 4 bays enclosure (filled with 4 x 3.5 inch hard drives.) Even before 10.10.2 I was having strange problems (like SecuritySpy cameras freezing up when powering on the TB4; strange indeed), but now things are more serious with consistent crashes restarts of my MacPro whenever the TB4 is powered off. I had tried a lot of different fixes, but none of them solved these problems.

Following several suggestions here I now program (using Keyboard Maestro, a great macro program) my MacPro to sleep before my automatic power timer turns on or off the TB4. Also I discovered that the TB4 needs about 30 seconds to totally sleep after the MacPro is put to sleep; after that period of time I then shut off the TB4 power (using a programmable power timer). A bit of a work-a-round, but no more MacPro crashes and restarts, and no more SecuritySpy camera freeze-ups. I also use Mountain to mount and eject external drives at night for my nightly backups. Similar to Jettison.

It is unfortunate that for some people the sleep before powering off does not work for them. Try waiting a minute after sleeping before powering off.

In any case, I think the crashing and restarting is a new problem created by OS 10.10.2. I hope Apple fixes this sooner than later.
