    Hi All,

    I tried posting a comment in the group regarding running Mojave on an unsupported Mac but the comments are fierce and fast.. mine just gets buried, so I'm starting this thread as I'm sure there's many others in my situation.

    @dosdude1 has done an amazing job of getting the installer up and running for the Mac Pro 3,1 - however, one issue remains and I (and I'm sure others) have a major question before we just go ahead and install the OS.

    My Mac Pro came with an EFI Radeon 5770.. which to the best of my knowledge is a no-go for Mojave. That card isn't in the machine anymore as I have a non-efi GTX 1060 (MSI Gaming X series in case this is important) running on High Sierra with Nvidia drivers. How can we install Mojave if the installer can't be visible without an EFI card? But the EFI card is not supported by Mojave.

    My understanding is that, the GTX 1060 will work just fine under Mojave with the Nvidia drivers installed, but of course, no way to install them without being able to see the operating system in the first place! I feel quite list in this situation and need to find a way around it.

    Would anyone be willing to create a restorable DMG with Mojave pre-installed with the Nvidia drivers? Obviously only makes sense to do this once the OS is fully released.. but I can't see any other way around it.

    This forum has always been super helpful to me, and @dosdude1 has even helped to solve an issue I had with the GTX 750 ti and High Sierra.. so I'm hoping that he or someone else here can throw me and others in my situation a lifeline.

    I have the exact same machine, exact same cards and will install the exact same OS when it's released :) My guess is to install with my EFI-capable Radeon 5770, then install nVidia web drivers and put the GTX 1060 in. I can share fresh DMG if I suceed :)

    But you wont be able to boot into the OS with the 5770. Not to the best of my knowledge. It's not a "metal" card and it wont work under Mojave. It's really disappointing to not see any other responses on this thread.

    @Zlobnick did you do it?

    Yeah, I installed Mojave today using both cards at the same time. 1060 in slot 1, 5770 in slot 2. All went flawlessly using dosdude's Mojave patcher. I even get a usable picture in Mojave with 5770, but it's slow. But it's enough to install nVidia web drivers which haven't been released yet :(

    Some news - I have a reason to believe that when Mojave nVidia driver gets release I'll have big problems getting it to work. I described what happened with my High Sierra installation in this post.

    @Zlobnick - Did all work out? If so, what steps did you take?

    Thanks :)

    For now I'm waiting for Mojave nVidia web drivers. Everything works OK with ATi 5770 in Mojave and with GTX 1060 in High Sierra.

    Yeah! I just realised (after successfully upgrading to Mojave) that Nvidia STILL hasn't released them. I see a lot of back and forth on forums, but they need to get their ass moving on this!

    As I understand the main reason we haven't seen Mojave drivers yet is Apple's driver signing process that hasn't been done yet :)
