ctrl-click does not work any more. So there's no way to place a single item on a workbench, you always move a whole stack. I discovered this by accidently crafting 10 diamond trousers after a day of strip mining, this really sucks.

I know this has been reported before and Mojang says it's something with ALL versions and Java and sun spots and whatsoever (I really don't care about your excuses for not complying to Apple Developer agreements) but PLEASE: give us at least an option to assign another key like holding 'alt' or whatever. Like it is now, it's no fun any more. I am not going to start using a mouse just because some Mojang guy is unfamiliar with trackpads and Apple standards.
