My G5 Dual had a complete freeze while on Safari/Leopard Webkit. When that happened I had to shut down manually and after restarting, my new backup drive proved irreparable. Then, strangely enough, only 2 days later the main drive stopped working too. I had to use my Ibook to get all the important stuff from my G5 HD, in target disk mode. I had the G5's backup drive replaced in the shop, and then I could move the bigger files there. After that I finally was able to erase and reinstall Leopard onto the main drive from my original 10.5.4 DVD. Then I began moving stuff there from the other drives. (I now wonder for instance if one should get all software updates first before importing anything from backups...) It's been an arduous task. I must have made mistakes too. One was probably that I didn't save enough applications as they had been on my previous Leopard. I've copied some from the Ibook. (I did save libraries in the home folder, and I've repaired tons of permissions.) But, some applications won't start now, including Safari, which is central as I can't get to download anything without it either. I did reinstall Webkit from my archive, and also tried Safari without it, but same result. The internet connection itself works, however, and I got the combo updates etc. (Yes, I did ignore the Safari update over Webkit.) I'd have to copy hang reports onto a USB drive to paste them here... but I do have a few short crash messages from Dyld : 4 times I got "Symbol not found: _kCACFLayer" (expected in QuartzCore), and once I got "Symbol not found: _WebActionFormKey" (expected in Webkit. Not sure now if some of those occurred when trying the default Safari...) Itunes won't start either, it just asks for Quicktime 7.5.5 or newer, although I have 7.7... Other times I just get a "?" over the Itunes icon. I have no other browser, so obviously I should either fix something in situ to get Safari working, or import something from another drive. Should I copy the latest Webkit from the Ibook to the G5..?
