Help!

*hands* I am done searching!

Can anyone recommend a good tutorial on making gifs for tumblr using a Mac. I found lots for PC, but Mac seems harder to find (this baffles me completely!).

I need it from capturing (and the best program for that) through to making the gif. Photoshop is cool, I just need to be shown (or told) how to.

I will crack this dammit!

Thank you if anyone can assist. <333
