Hey guys, I have a problem I've been fighting for the last week or so. I've bought a MacPro11,1 retina (late 2013) without the NVME SSD, have installed an aftermarket NVME drive, it shows up during install, I can install on it, but after the initial install it does not boot from it, and it does not appear in startup manager. I currently have in the running of a USB stick with 10.13.6 and I found out that the boot ROM version is MBP111.0138.B14, what is the latest version you guys have for the EFi and Boot ROM versions. How can I update that? or do I need to find an original Apple NVME for this model? Thank you in advance for your reply!
