Why you need to run linux in a mac book?
Such as alt-tabbing doesn't cycle through the windows an application has, just the application. If I have three Sublime Text 2 windows open, I have to hunt it down like a predator.
So I just installed VMWare, and setup my Linux Mint 13 machine and work there exclusively now.
It will show you the windows for that particular application.
I found that VMWare workstation & parallels with the i7 imac (2011 model or something? it is a brand new iMac 27") causes mass tearing when using Linux, maybe a vsync issue?
Using parallels seems to lock the vm at 60FPS so it feels natural. Back to being productive....
