Hello Everyone, I am a - happy - user of a Mac Mini 2011. It is a dual core i7 2.7 GHZ with 16 GB of Ram and 500 GB Hard Disk. I added a Samsung SSD 830 two years ago and I am using it as a DIY fusion drive. I did not update to Mavericks because I did not see any reasons to take the riske of screwing my fusion drive. I am still waiting for broadwell minis, and given that my Mac is still as fast as the present generation, I will not update to the 2014. So far so good. However, I would like now to enjoy Yosemite and Handoff. In theory the bluetooth chip installed in it is capable of doing it - hopefully apple will not block it via software. Any tips on how to do the upgrade and preseve my fusion drive?
