I am having trouble downloading and installing 10.13.6 on my MacPro 5,1. So far I am able to get to the MAS High Sierra page. In the upper there is a button that says "open". I click it and the installer says I need a firmware update to proceed. I thought I had already done so in the past, but I do it anyway. After almost ten minutes it boots up and goes back to High Sierra page. I again click open and same thing, tells me I need the firmware update. I do it again incase something was missed. 10 minutes later, same thing.
Is there another way I can download High Sierra? Why is it prompting me for the firmware over and over?
BTW my firmware is... MP51.007F.B03 and I am running El capitan.
