I'm new to SSDs, if I plan to put this is my old MBP (2006), do I need the installation kit? Or is the installation kit only needed for desktop installs?
It would work in MBP, but Samsung does not provide utility for Mac. You cannot even update the firmware without a Windows system. If you can first hook it up to a PC to update the firmware (the latest one is F07 from December and the current batch is shipped with F06), it would be fine for you MBP. The new firmware improves performance after prolonged use when files are fragmented.
