Hi there, I'd like to fully erase the internal SSD of my MacBook. After a few beta versions of Yosemite and some other stuff, the drive has become slower. That's why I want to erase and restore the SSD to factory settings and performance, before doing a clean install of OS X Mavericks. It seems there is an option to do this with PartedMagic, but I have no experience with this software and I have no idea if this is the perfect solution. Could you guys please help me out?? Thanks a lot in advance!
