Hellooo~!

I just have a quick question for all you techno-savvy people out there!
So I recently just yesterday got a mac as a graduation present! Huzzah!! (>u<)b ..Unfortunately, I've just been made aware that I can't download SAI onto it because it only works for Windows DD: *DEPRESSION*

Anyway, I was just wondering if anyone would happen to know of another program that I could possibly buy or download for my mac?? Just because I wanna be able to keep drawing and uploading stuff when I head off in the fall..:'D But yeah, preferably something that can be followed with a link.. just because I live in a very, uh,, secluded province with little to zero chance of finding anything legit at any "electronics store" we have here..

Just something to keep in mind~: )

So yeah! Any input at all will be much appreciated!! Thank you everyone in advance <33
*sits and waits patiently*
