hey buddy - is the ipad processor faster than the G4?i have a friend who photographs his negs like a contact sheet with his 5D mkII works really well. easier than darkroom printing or scanning!
My G5 does the same refuse-to-shutdown crap from time to time too. Not sure what causes it, but giving it one or more of the usual suspects usually solves it (repair disk permissions, Safe Boot\Restart, run Disk Warrior, Reset PRAM etc.) I have also had some luck with logging out and then shutting down. I must concede that my Windows machine trumps all in this regard: hit the power button on the thing and Windows starts closing apps, (force-quitting as necessary) and then powers off. Way cool. So far it hasn't gotten hung up on anything, but maybe that would be different if I had open documents that needed saving. Really all that would be needed for a completely hands-off shutdown would be for each application to save whatever the hell you had open in a temporary directory and then ask you to sync up that and your original source file when you came back to it. But try shutting down a Mac with an unsaved file anywhere and you're SOL. Well like I said, maybe I'd be SOL on Windows too. I'll have to test it.
My drives have always been formatted with Mac OS Extended (Journaled), (don't know what that means…yet, but that's what I've always used) but I don't see how that has anything to do with the Shutdown problem. If you have an open document with unsaved changes made to it in any application and you hit the Shutdown Command it will not work. The app will not quit and the shutdown process will stop. As far as I know there's never been any system-wide, intelligent solution to this problem. Sure you could make each app save the open documents before quitting, which could be good or bad. Good if you made desired changes and forgot to save, bad if you were messing around and didn't want to keep the changes. That's why a separate copy would be ideal, the only way it could be done without further user intervention.
You're never worried about losing anything you mean! I read up on it and I'm sure it has saved our bacon on many occasions, but then again I am not sure of what it's like to use non-Journaled. I'm reading some interesting things about it, thanks for the tip!http://apple.stackexchange.com/questions/7609/what-are-the-differences-between-journaling-hfs-and-non-journaling-hfsSystem was re-installed not long ago as it is a new machine after my old one blew up. It must be software-related because the old one would do the same thing from time to time.I know that a reformat and reinstall is great, but there's just sooo much stuff to reset afterwards. It's like taking a leaf blower to the beautiful stack of cards you just spent a month building. I wish there was a way to completely isolate operating system files and user files so that you could cleanly reinstall the OS at will and not have to go in and reset your e-mail and application preferences etc.
