Set TextMate as the default text editor on Mac OS X

keep in mind, this will be on a per file extension basis, so you will have to do it for a file of each file extension you want textmate to be the default editor for.

Correct, I've done this for Sublime editor. Sweeping changes make me a bit nervous that it will go way too far (good luck rolling back) and there's really only a handful of file types that need altering. I do them on an as needed basis.

Hi,I do as you said,but only work for one file,not for all of them.

@Ben After selecting TextMate from the drop down you must hit the "Change All..." button and confirm. It most definitely works, as I said I do this myself.

@Ben you need to make sure and actually right click > Get Info, and look for 'Open with:' in that Info view. This is different then right clicking and doing 'Open With' right from that first menu. I initially made this mistake and it changed only that one file.
