Can somebody with an up to date Mojave installation on a 2015 Retina MBP tell me what the boot ROM version is in System Information?
Mine is MBP114.0182.B00. I replaced my original 512 GB Apple SSD with an OWC Aura Pro X 1 TB last April and it successfully updated through the various combo updaters for High Sierra, the Mojave installer from September last, and the 10.14.x Combo Update installers through 10.14.2.
Tried to install the 10.14.3 Combo Updater today and the updater said that it couldn’t be installed on this disk. OWC told me that I needed to reset the SMC…which I doubted but did it anyway…no ROM update and still no 10.14.3.
I was able to update to 10.14.3 using Software Update in System Preferences…but that didn’t change the boot ROM version either.
I’ve got the original SSD from Apple in an external USB OWC case…it’s still on High Sierra soI’ll try updating it to Mojave and see if that makes any difference…but in the event it doesn’t and the ROM needs updating any idea how to go about it? I would hate to have to put the original SSD back in just to get things right.
