How to restore specific system settings from Time Machine?

[windylim]

Hi, if I have made some changes to preference (eg network) that I want to restore/reverse from a older Time Machine backup, how can I do that?

For the matter, (hypothetically) if I needed to restore something more complicated (eg I updated the OS to a new patch, and found it not working well and want to reverse), is it possible to do it by Time Machine?

Thanks!

1) Yes, this is possible. You just need to know which preference file contains the information you wish to restore. Alas, this isn't possible through Time Machine's interface, unless you happen to know both the folder that the preference file is stored in, along with which specific preference file needs restoring.

2) The simple answer: No. It would be nice if you could do this, but it does not work.

Ok, I'd wrote a very long explanation of how easy was to acomplish the second thing you asked for, and the stupid couple (safari/macrumors policy to erase passwords that seem too "easy" to guess) just made me lose it all. I have a broken/immobilized hand, so writing with just one hand is even more excruciatingly slow.

Short version: after a system update, to reverse it, just restore the ENTIRE hard drive to a point before the update. PLEASE NOTE you will lose ALL work you have done since the update.

Hope this helps.
