This is the yearly reminder that we do not support beta operating systems. If you want full support and reliability, please do not update to the latest betas. If you do so and things break, do not expect us to immediately fix anything to make Channels work on a beta Operating System.
If you do install it, and things work great, or things are bad, feel free to report them. This is helpful. But we generally don't get things ready for the new OS until it's released, because Apple ships VERY buggy betas, and we don't like to waste our summer fixing bugs that Apple introduced.
