Hey guys, I just scored a Mini 2012 with 16 gigs of RAM and a 120/500 Fusion drive for 390 . Before I install the thing (getting it tomorrow) I'd like to know if there's a stress free way to replace the 500 GB HDD by a 1 TB one and still keep it bootable. I don't have any other computers here, so it needs to work. I do have a super old external drive I want to get rid off, but that still has a solid terabyte of music on it. How do I upgrade the HDD without the Mac becoming unbootable? Thanks guys!
