Hey, this is John Simmons, the tech Doug was speaking of earlier. I remembered that Doug and Chris were right on top of that old "Type 8 camera.app" issue awhile back so I thought to check their blog and I noticed they hadn't posted anything on the "10.5.6 burst-of-doom" yet. So I called Doug to see if they'd seen the issue yet. I posted about it in the "Digital Cameras..." section a little while ago:http://luminous-landscape.com/forum/index....showtopic=31019
.. but i noticed this post and, anyway, you guys seem like you may be more familiar with the topic.
We were very excited about finally being able to use the 1DsmkIII tethered with the new 10.5.6 update, and it really was great until we got to 120-150 frames point whereupon it would freeze CaptureOne or EOS Utility (beach-ball forever). We've reproduced the crash about 6 or 7 times, both with the 1DsmkII and the new 5DmkII, and also with our 17" MacbookPro.
We finally heard back from Canon that the new EOS Utility was not tested with Mac OSX 10.5.6 and that they recommended not upgrading to 10.5.6 until they release an update. But 10.5.5 was so slow we ain't goin back to that either. Downgrading is a big hassle anyway.
Formerly the only remedy was to restart the computer, but as I was testing today I found if we used "Activity Monitor" app we could force-quit the application "Image Capture extension" (after force-quitting CaptureOne or EOS Utility) and that would allow us to reconnect our Canons without having to restart, but we would still consistently lose our last 10-14 exposures. Boo!
So anyway I am really pretty confident that the problem is the new OS upgrade. Whatever they changed with the USB has turned out to be a resounding failure with a number of people. In just researching this problem on the Apple forums, I can't tell you how many posts I ran into about the 10.5.6 update causing folks to completely lose their keyboard, mouse, wacom, flashdrive, usb harddrive, ipod, you name it.
But it is really sweet for a little while... watching those captures fly on in. If only we could get the photographers to SLOW down a little bit I bet this wouldn't be so bad an issue (yeah right, the only reason they're shooting DSLRs is because they're supposed to be fast). Anyway, feel free to chime in if you have any thoughts. We're kind of getting frustrated at this point, so I appreciate any help you can offer, maybe even trying to reproduce the error yourselves, if you have any spare time. Thanks.
