Not until I can purchase my very own mac computer, because they do not allow development on anything but their operating system.
And it's for this reason (among others) that I would never support Apple or any of their products. I like to use Flash just because Steve Jobs hated it so much.
it's worse than that

The Apple OS license requires you buy a computer from apple to run the OS.
The license means you can't even buy OSX and run it in a VM.
... even though an apple is just an over priced intel PC ... running BSD (which isn't all that different to Linux)
people love their walled garden, I have no choice but to support people that have apple products, so I have to know all the ins and outs of the os and products. without doing a hackintosh or spending $2k, i know little other then what i can google up, which is just enough, for now.
... and that is only 5-10% of my customers and 1% use some flavour of linux.
