Photoshop & Bridge constantly crashing on 27" iMac
Good afternoon,
Im just off the phone from my local Apple Repair people and I am at loss as to what to do next.
I have a 27" iMac in for it's second service to try and find a continuing issue which hardware tests say does not exist. The machine was 1 of about 10 I bought all with the same spec - iMac 27" 3.4GHz Quad-core Intel Core i7/8GB/2TB + 256SSD/AMD 6970M 2GB.
With this one machine I have rebuilt it probably 4 or 5 times since new. 1st time the machine went for service there was a problem with the video card and that was replaced and returned but when I put it back into a Photo studio for use I think we might have got an hour out of the machine before I had to take it out again ! Software being used is Photoshop CS5.5 and Bridge, and the camera's software which is Canon EOS Utility for image capture.
We shoot tethered ...
What we have found is that once a shoot starts and the iMac is capturing the shots (via the USB cable) the apps crash and are unable to be quit, need to be force quit if we can and the machine then also locks up. In fact when I had to do a change over I found the iMac sitting on the startup sprocket going no further. I had to "pull the plug" to get it to shutdown.
My initial thought was that the SSD was at fault so I installed a brand new downloaded copy of 10.7.5 installer and installed it on the second drive (the HDD) then reinstalled the Photoshop and other apps. I then asked another photographer to try it again and left the room, grabbed a coffee, and I didnt even get to have a mouthful when I got a call saying it had crashed straight away !
As I mentioned above I have just had a call from my local Apple store telling me that their Hardware tests say nothing can be found and that it is software related, but after doing the number of rebuilds I have on this machine, I dont think that another rebuild will make any difference !
Im thinking it's either ram or something on the logic board, but I dont think my friends at the store will be replacing either of those ...
Anyone with similar experience ?
Regards
Mitch
