EDIT: Ok, I remember now: iOS development :)
I have installed Hackintosh on a netbook some years ago and as far as I remember you needed to take care not to agree to an OS update.
It's vanilla so I can update it for the most part no problem. Just gotta make sure my kexts are updated to support the OS. It's not as simple as an actual mac, but it's close.
It's pretty amazing. It boots up, shows the Dell logo, then the Apple logo, then it's up. Brightness, sound, thunderbolt, usb 3, wifi card had to swap but that was $20. Bluetooth, it all works. Keyboard backlight, multitouch trackpad, sleep.
I feel that sometimes Linux can be a hobby, more than a productive machine. I realize that there are distros out there that cater to people like me (Elementary comes to mind) but there just some things that work better on MacOS.
