It's ha

its hard as heck to write one line of metal code- writing the whole thing. Wow.

Yes - I've written some metal code for a while now and what's being suggested is not only hard but practically impossible. Metal is designed from the ground up to be "close to the metal", hence it's name. Bypassing a lot of CPU overhead in moving buffers of data around to let your GPU accelerate as fast as possible (eliminating a lot of lag). That's why you get the 10x draw call performance compared to openGL. It was an answer to DirectX and Vulkan for gaming and compute intensive work. So they sacrificed "programmability" for pure performance. Very gpu/hardware specific.
Only time will tell if there gamble will pay off, but this is a big blow to all our "unsupported" machines with 4+ year old embedded graphics cards. They've deprecated OpenGL and OpenCL, which means no support and some of the compatibility glitches we're seeing. I just hope they don't actually drop it from their framework.
I'm also curious to see how NVidia drivers will play into all of this. But no peep yet on NVidia Mojave compatible drivers (I think?)

I recently got a MBP 8,2 on the cheap, and I love it. I hope Radeon 5xxx/6xxx acceleration gets figured out in the coming weeks/months, as I'd like to move this to Mojave, just like my MacBook 7,1 and my iMac 9,1, without having to disable my GPU.

Carve out a small partition on your internal drive, or install it on an external drive, to give it a try. Mojave really is nice on the 8,2.

Got back from vacation and running DP5 on MacPro 3,1.

I sold my Flashed GeForce Titan X Maxwell card mainly cuz I needed money for vacation.

More than likely will either go with a NVIDiA PC card and keep the Mac stock 8800GT NVIDiA card for a boot screen on an older display. Will be cheaper than buying a flashed card unless Apple starts selling Mac cards at a cheaper price point. Doubt it.

Gonna hold off and see what NVIDiA cards Apple officially will support at launch. I know many will work but might just get one that Apple at least has drivers for to avoid having to play the driver game. But at least NVIDiA does supply drivers.

Starting to hate ATI/AMD cards now. My ATI card is currently runnng Windows 10 only mainly because when I try to dual boot it somehow messes up the PC partition. I used to be able to fix it with Winclone but that is messing up boot partitions too with super slowness thst is unusable.


Anyways I have one NVIDiA 8800GT Mac Pro 3,1 dedicated to Mac only booting Snow Lepoard, High Sierra and Mojave. And the other AMD 7xxx GPU Mac Pro 3,1 runnning just wind-blows 10.

Btw, I can run Mojave with the AMD 7xxx card w/o acceleration using the patched drivers which just lets the card run without transparency. What is weird is it will temporarily run with acceleration until you login to the finder and the bar is transparent for 1-2 seconds and then goes solid. Even the welcome screen computer animations are smooth. I may one day mess around with SSE4.2 emulation but at this time I am down sacrificing my PC Mac Pro’s disk. part of the issue is Apple not updating the MP 3,1’s EFI.

Has anyone deleted their HS partition yet? I have El Cap (125), HS (75), and Mojave (50) and I am considering just deleting the HS partition to make my Mojave partition larger. My partitions are weirdly glitched, so I can't adjust any partition sizes without deleting a partition. The way it is right now is that the end of one partition is the beginning of another, so it will not let me just make my Mojave partition take space from my HS partition.

I finally was able to install (and boot up successfully) Mojave on this unsupported MacBookPro5,3.

Thanks to your suggestions @jackluke, @TimothyR734 and @ASentientBot.
Used an external Hdd/Sata drive instead of USB thumb drive. Along with the internal SSD drive that has 2 partitions (1) High Sierra (2) El Capitan, I now have a (3) Mojave partition.

I do have 3 issues at the moment that are not that critical:
* Camera is not recognized (although I used @dosdude1's iSight patcher.
* No Wifi.
* Bluetooth is not on the Preference panes. So I cannot pair any of my bluetooth devices.

That's it for now. Thank you all and best regards.

Open your machine and ensure the secondary display cable is connected to your logic board. That is what the camera, WiFi, and Bluetooth modules go through.

You can never adjust a partition size from the beginning, only the end. It's a limitation in HFS+ I believe, in APFS this isn't the case.

I haven't touched HS in a few weeks. My SSD is Mojave-only :)

same here, my HS SSD is collecting dust right now in my storage drawer.

Edit: I know it’s possible, but is it compatible with patched Mohave and HS or will it break the patch?

It depends on what machine you have... If it natively supported High Sierra and has the latest firmware update installed, it'll work fine. Otherwise, you'll need to wait until I finish my APFS ROM patch, which should be done very soon.

Would it work on HS on non-native support or would the patch be for both versions?

@dosdude1 how can you check for EFI uodates? Not about apfs as j have native support, I'm just wondering (also thanks for your continued hard work.)
[doublepost=1533528914][/doublepost]Also can mechanical hard drives use apfs in Mojave

Hi dosdude1. I guess this APFS ROM patch is different from the APFS boot rom patch, which is working wonderfully BTW.
Thanks as always.

No, it's the same thing. It just had a bug that was causing machines to become bricked, due to an issue when determining the correct EEPROM model. As such, I have removed it until I fix this issue, to prevent people from damaging their systems.

I cant update anything on my Late 2008 MBP through the patch updater. It keeps giving me the same error. Has anyone run across this as well?

Thanks for update—guess we MP3,1 owners were among the lucky ones. The NVMe boot rom patch is working well with HighPoint 7101A too. Now I just need to find some spare cash to fully populate the board with 970s!

APFS here on MacBook 5,2, iMac 8,1 and MacBook Pro 4,1 and 5,3 and a MB Air 2,1
works well (some machines already patched, some with the EFI boot helper partitions, waiting for the new ROM patcher ;-) )
Click to expand...

If I'm not mistaken, are you waiting the APFS ROM patcher update only for your MBA 2,1?

Do you remember if when replaced your EFI CHIP it was a "WinBond" or "Macronix MX"?

And I turn the question over to @dosdude1 if I write the original binary EFI ROM file into a QFN WinBond chip, it will work on a machine with a previous QFN MX chip ?
(I meant only with stock EFI ROM without any following APFS ROM patching)

After updating to Mojave on my mid 2012 MacBook Pro- look what we have here. After a restart it went back to normal look though. Anyone else experienced this?

Edit: Spelling fix and serial number
