MP 7,1 Mojave on a 2019 Mac Pro 7,1. Time to hack.

[rea987]

Yes, those can work too if one is looking at upgrading just the performance of their single graphics card only but that isn't a 9 year newer Mac Pro with much faster and more CPU cores, software support, multiple graphics cards and selection running at full speed and power, tons more ports natively supported out of the box, a pile of PCI 3.0 slots and on and on I could go.

I am simply looking a reliable way to run Mojave on Mac Pro 2019 natively. I have a Steam account with around 5k games, there are hundreds of 32 bit Mac games that I do not wish to use with Wine, Vmware or any other translation or virtualization solution. I do wonder whether OpenCore Mojave can be installed into MP 7,1 by using a Mojave supported high end GPU of its time. How about ssd, cpu, ram, lan and wlan support? Would they also require Mojave compatible downgrades? Thanks!

Wow that is a lot of Mac games! You really have a BIG reason to get that working on a 2019 Mac Pro. I couldn't answer the question since I don't have a 2019 and this is the first I have heard that it might actually be possible.

Well, that's a family share account. I have 1k, my friend has 4k games, I filtered the games for Mac, there are around 900 Mac games. My friend's most games are Steam card farming nonsense but most of my games are legit. Well, I might check hackintosh solutions for Mojave in the end... 😑

My Late 2011 17" MacBook Pro with an AMD dDGPU originally came with Mac OS X Lion 10.7.2 (11C74). I bought it used later.

It was able to run Snow Leopard 10.6.8 when booting from a drive/partition where it already had been installed on from an older Mac, with all updates and fixes. And it ran perfect. Extremely fast and not a single crash.

Since there never was an installer for 10.6.8 I couldn't try if that would have worked too. The standard installation disk that you could buy from Apple (until not that long ago) included only 10.6.3 and didn't work.

I also had those grey installation discs from a Mid-2011 27" iMac that was either 10.6.6 or 10.6.7, I think even 10.6.7. They did not work too, to boot from.
Those grey disks that came with the devices often don't work with other Mac models in general but I think I read somewhere it would have worked if mine was the Early 2011 17" MBP. I think both the iMac and the MBP had the same or very similar AMD GPU.

Edit: Maybe it was just because the iMac released a few months before had the same GPU, so the drivers where already in there. I am also not 100% sure if those iMac installation disks didn't work. It could have been others I tried before that did not work and when I had those iMac discs, I already abandoned Snow Leopard. But when I think about long enough those disks may have worked.
It was just a long try before and from somewhere i had a grey 10.6.7 disc that didn't work. Could be the disc was just incompatible to this Mac for missing driver reasons.

I doubt you'll ever find a way to make it happen. ProxMox is probably the closest you'll get.

The biggest thing you will need to do is to inject "-no_compat_check" into your boot arguments. There's
one way I can imagine you doing this.

The first way is to install Mojave on a secondary drive using a supported Mojave computer. Then once booted on the second computer, run this:

sudo nvram boot-args="-no_compat_check"

Then reboot. Note that you will need to disable SIP to inject boot arguments at runtime. Then reboot to ensure that it will boot with the new boot argument.

Then take the drive and attach it to your Mac Pro 7,1. You should be able to boot from it right then and there (horray!) but if you want it on your internal Apple SSD blades, you will need to clone to those drives while booted from the external.

I'm not sure that'll work, and obviously I do not have a 7,1 to test it, but I think this is enough to get you started.

OK its 2025 and I will give it a shot. The idea is I want to bring my Mac Pro 5,1 along for the ride when I need to use a tool that wont migrate with me while I develop new ones with the Mac Pro 2019. Also am going to try VMware Fusion 13 as well. Also not sure if the Radeon Pro W5700X MPX Module (16GB) will even support Mojave.

I would go for the readily available 580X if I was trying, since the W5700X was not supported.

As a reminder, always copy (using CCC5, with Get Backup Pro 3 as a backup) Mojave into MacOS Extended-journaled partitions for use on rotational or Fusion internal drives (especially applicable to those machines that Apple made a PITA to open, e.g. 21.5" iMacs, etc), and always disable SIP, MDS_stores, MRT, Report Crash, and Spotlight Indexing to glean the most performance.

VMware Fusion Pro is now free for personal use. I just installed the second to latest version of VMware Pro and dropped my copy of the Mojave install on the create new page and bang it came up great. I even figured out how to move my copy of CS6 on it and it runs fast.

Yes, I have a CS5 install running on Snow Leopard Server in Fusion Pro, but it's not the same experience as a full bare metal OS install - no option for multiple displays, for example.

Also, macOS Guest is a deprecated feature now, so it's going to become increasingly non-viable going forward.

Multi display is handy but I use adobe for real work once a month. Just not worth the $800 a year subscription

Note that Parallels VMs of Mojave (and probably other Mac OSes) will not have OpenGL support (for reasons I have yet to fathom given that Mojave itself supported it), meaning that most games won't work even with retained 32bit, so the poster has plenty of good reason to see Mojave hacked/forked/etc to run natively on newer hardware.

I didn't know this. Thanks for letting me know. That is my main reason for using VMware Fusion Pro.

Does GPU passthrough to Windows work yet?

 

[benmuetsch]

Isn't it possible to boot a pre-installed Mojave on a 7,1 using OpenCore or simply no-compat-check via external SSD?

I mean, the 7,1 is not too far away from an iMac Pro which is natively supported.

Running Mojave today, presented by ...

@6 min he explains that old Apple app versions can only be downloaded if one has purchased them earlier.
Something I also have learned when I suggest for macrumors forum users to repurpose old hardware.
As I had purchased some apps years ago, I thought it would be as simple as choosing an older version. But that is not the case.
