Hoping to get some guidance, and sorry for the noob question. Purchased a new SSD (Evo 850) and 16GB Ram for our 2012 base model mini. Never done this before, but the hardware procedure/installation seems fairly straight forward. OSX re-install procedure on the new drive has me a bit confused though. It seems I need to make a recovery disc on a USB drive according to iFixit. Do I need to find the OSX version that originally came with our Mini (not sure what version it was), or the newest version that is now installed (10.11.3)? Was hoping I could just swap out drives and not use a recovery disc, looks like that is not the case.
