Here is my dilemma: I have the Mac Pro 5,1 (Mid 2010), BOOTRom MP51.0089.B00, running High Sierra 10.13.5 . 1. I have PCIe SSD (four of them Raided to read as one drive...sorry I'm not all that tech savvy. Please bare with me). I can't upgrade to 10.13.6 because it keeps telling me that it doesn't recognize the raid...something or other. So I would always take it elsewhere for almost every update. It's a pain not to be able to update the regular way, in the comfort of my own home. How can I go about this because I'm tired of the back and forth from home to the center, the almost two day wait (I have projects to complete), then back home afterwards. Keep in mind, I'm willing to do clean installs because my projects, my life, is all on externals. I always leave the internal drives to only work the applications and OS. 2. My graphics card is the NVIDIA GeForce GTX 980 4096 MB . After I get 10.13.6 in, with this card, can I upgrade to Mojave then? Or am I stuck at 10.13.6? Any help will be greatly appreciated. Thanks!
