There are already plenty of guides that explain the particular steps of getting Git and Github going on your mac in detail. While the steps below should still work, I recommend checking out the new guide if you are running 10.9!

There is an updated version of this post for OS X 10.9. 19, 2013 Beginner's Setup Guide for Git & Github on Mac OS X

Git will then finish bisecting and take us back to our previous HEAD revision.Mar. Once we've found the culprit, we can end the bisect process and wrap up: $ git bisect reset This process is repeated until we've successfully singled out the bad commit! And again, it will check out a revision in the middle and invite us to do some testing. Git will use this information and repeat the process: it now splits the original commit range again - but depending on our answer, it will take either the first or the second half. As soon as we've tested this, we need to tell Git the result, either with git bisect bad or git bisect good. It's now on us to run / build our application and verify if the bug is still present or not.

Git will now check out a revision in the middle of this commit range between 'good' and 'bad': Bisecting: 3 revisions left to test after this (roughly 1 step) With those two pieces of information provided, the actual 'bisecting' process can start. As soon as you've tested and verified this, we can go on: $ git bisect good fcd61994 But it's probably most effective to start by checking out an older revision where you are quite confident that everything was still fine. Providing the 'good' commit might be a tiny bit more work. This means we can simply provide 'HEAD' as the bad commit: $ git bisect bad HEAD The bad commit is often easy because, in most cases, the current state is buggy. Now, Git is waiting for us to provide both a 'bad' and a 'good' commit. First of all, we have to explicitly start the process: $ git bisect start Let's look at how git bisect works in practice.
