    After the OSX 4.10 updates I started to get multiple kernel panics from my wireless card. I'm assuming it's the software update that is causing this so I want re-install OSX. However I have a lot of programs, plug-ins and logic sessions that I can't easily take off my computer and I was wondering about the archive and install feature. Will it protect all my user data? Is there another way I can "roll back" the OSX update?

    Thanks in advance.

    Basically, it saves all your previous system files away in a folder and reinstalls OS X. You can't boot up from this folder but the files and stuff you want should be safely in there. It's worthwhile backing up your Mac before this, of course, just to make sure you don't lose anything you want to keep.

    There's an article about archive and install here that you might find useful.

    Thanks very much, that helped loads. One more question, if it keeps all the old system files can I just delete them from the folder? how much space will it take up?

    It'll take up a few GBs and it's fine to delete the entire Previous System Folder assuming there's nothing in it you may still want (highly unlikely). :)

    You don't need to do an archive and install. You can, but you will have to reinstall any system level plugins, drivers, etc...

    All you need to do is go to apple.com and download the Mac OS X 10.4.9 combo updater. That will roll it back to 10.4.9 without losing all that other stuff.

    I downloaded the combo intel update but for some reason it won't let me select my hard drive, it says it does not meet the requirements for it.

    Any ideas?

    You Have To Reinstall 10.4.x From Your Install DVD

    You have to reinstall 10.4.x (I recommend Archive and Install mode) from your install DVD then the 10.4.9 Combo updater to get back to 10.4.9.

    Yeah, the 10.4.9 combo update will not let you override a 10.4.10 installation. :eek:

    Sorry for necro'ing this post, but I did not find a clear cut answer.

    If I did not move the default locations of the files I imported into iPhoto, iTunes, etc, will Archive and Install save those when I use it to re-install OS X?

    Yep. It should keep everything within your Home folder. :)
