Subject:Backing up OSX applications
Time:09:21 pm
I've been running into some problems with my iBook (including several crashes) that make me feel that the system is getting a little flaky. The trouble is that it's running OSX-10.4 and can't use anything later, so the only way to fix things will be to wipe the hard disk and reinstall OS-X. I don't have a backup that's recent enough to be even slightly useful, because I don't keep anything important on the laptop.

The main problem this gives me is a few relatively small applications that I don't have master disks for - mostly shareware I've registered etc., like a webcam app I use for my digital microscope.

The applications I want to save are not involved in the crashes, as far as I know.

Is there any simple way to back up individual applications and reinstall them? Can I just copy them to a memory stick or DVD-R and put them back later? Or is it more complicated?

Hello - a recent lurker here!

All you should need to do is copy the application from the application folder to a back up disc or drive, and then copy it back again. Everything is contained within the package, unlike with Windows programs that leave configurations and registry settings in unexpected places.

Thanks - I was hoping it worked like that.

It doesn't, always. The library folder, either the system library or your own, can often contain stuff — templates in iWork, for example. Often things like registration codes are stored there or in a prefs file.

Make sure you also backup the Library folder in your home directory, though; that often has prefs/license codes/settings for the apps.

OK - just hope there's nothing in there that is part of the problem.

Sometimes applications store stuff in the documents folder, especially games, for reasons that are obscure to me. So it might be worth casting a glance that way.
