It's my first time here. I've been looking around within the Mac forum and wondering if anyone else has been having issues like mine since upgrading.
I've already had to do a clean install of 10.5. I'm on an Intel Mac Pro. I lost functionality of my external iSight webcam recently. iMovie HD (version 6), iChat 4 stopped working as well as Photo Booth. No amount of troubleshooting worked. I suspect the wireless Logitech trackman played a part in it. I tried uninstalling Logitech's wonderful drivers but that didn't solve my problems.
Bit the bullet, wiped the drive clean and started over. Now I'm back to a functioning machine.
Adobe's Photoshop CS3 isn't exactly behaving well either. I guess Apple and Adobe and pointing fingers at one another on this. I just updated Photoshop CS3 to 10.0.1 So far so good.
I'll be checking back.
