A question for those of you who are TRIM/SSD experts: I have a 2012 Mac Mini that was BTO with an SSD. It's running 10.10.1. I'm contemplating adding a second (3rd-party) SSD, but the kext signing issues with TRIM enabler in Yosemite have given me pause. However, from what I gather, TRIM is all-or-nothing (i.e. you can't select which drives receive TRIM commands and which do not). So, if TRIM is already enabled for the OEM SSD, TRIM should also be enabled if I add a second SSD, right? Has anybody tried this?
