All kexts for pre-Metal GPUs are taken from High Sierra, which includes nVidia, Intel, and AMD kexts. The AMD kexts for the Radeon HD 5xxx and 6xxx series are the problematic ones though, that simply do not load under Mojave for some unknown reason. All the rest, including the AMD kexts for Radeon HD 4xxx series and older, load just fine. To get acceleration on your machine under Mojave, you'll need to disable the dedicated GPU. You can do so by following my guide found here, or performing my hardware modification.
Thank you for your amazing patch. I have searched but can't find an answer to this question - does your GPU disabler software patch for the MacBook Pro work on an iMac 2010 with the Radeon 5xxx cards? If so will it make any difference?My iMac runs really well, even the graphics are better than I expected (I knew the issue beforehand). Strangely the only real problem with the graphics is when scrolling using Safari!!

I would like to upgrade from 10.13.6 using the patcher but where can I download the dmg of Mojave? I am sure this is asked but cannot find it in the thread.
Bonsoir,
Avec "macOS Mojave Patcher" tu peux télécharger directement une copie officielle du dmg de Mojave (Menu Tools). Si ton Mac n'est pas compatible nativement avec Mojave tu ne pourras pas le télécharger autrement... sauf à le télécharger depuis un Mac compatible.

Installed 10.14 on MacbookPro5,2 with patched "native" APFS support. No problems. iSight works too.

EDIT: Also, fixed strange post-sleep double boot issue that went unsolved in 10.13.x

Hi All,

I see an issue not mentioned anywhere (I admit I didn't read the 309 pages :( )
I have a iMac 12.2 (2011, HD6970m). And after successful installation + patching I observe 2 things:
1) Login screen is SUPER slow, I manage to log in, but everything is super slow
2) The windows are reacting weirdly when I move them. The content stay where it is, the windows moves (so content is misaligned) and to refresh the content, I need to switch to another window. Then immediately the content is refreshed.

And globally everything seems slugish... Is it all linked to the Radeon I m using ? is there a way to disable GPU acceleration or reduce artifacts?

Thanks in advance for your help :)
I have your same system and don't have any problems, I had the same issue the first beta I installed with all the patch, then I did installed again but this time "without", the legacy graphics and that solved my problem, you can have a go, and experiment with and without legacy graphics.
By the way is your hard disk formatted as APFS? you need it.

To @fintematic @jackluke @0403979 and any others it may concern...

I think I've fixed the laggy iSight video on my MacBook7,1 by replacing /S*/L*/F*/CoreMediaIO.framework from High Sierra. (You can even do it without a reboot, it's not a vital system component like OpenGL.) Anybody else want to try this and confirm that it's much smoother with this change? (Please make a backup of the original!)

Edit: My previous comment to give some context.

Edit 2: Nevermind. Don't do this! It actually seems to do next to nothing. My camera just behaves in a laggy fashion in low-light conditions or when the computer is under stress. Replacing this framework eliminates some errors in Console but does not significantly improve the video quality on a MacBook7,1.

I am still glad I got a compatible Kepler GPU card. It's been 24+ hours and Nvidia has not released web drivers. It will be interesting if Apple and Nvidia have an agreement not to release new web drivers as Apple is only saying two Nvidia cards are compatible. One is the 680 and other is a Quadra 4000 or 5000? Apple really did not put much effort into that area. It's possible Apple's agreement with AMD is banning them from saying which other cards are supported. Meanwhile owners of Nvidia Video Cards beyond Kepler (Maxwell and Pascal) are waiting in the wings.

We all know you meant Quadro, but thank you for reminding me of Quadra nonetheless :)

Can share this file "CoreMediaIO.framework", I no longer have High Sierra, thank you.

Part two of my upgrade path for my Mac Pro 3,1 was to upgrade the copy of my High Sierra boot volume on an external drive (I already did a clean install on a separate partition). In both the upgrade and the clean install, my elderly Nvidia GTX 8800 graphics card does work but is only driving one screen instead of two. I'm sure this is an issue with the patched default Nvidia drivers and I'm sure that it'll be moot when Nvidia releases the web drivers at some point in the next few days (hopefully).

Regardless, I'm going to have to upgrade the video card in order to support a Samsung 27" curved monitor supporting 3440x1440 resolution, which I can't be driven through legacy DVI. An Nvidia GTX 680 is ideal (and flashable) but they are hard to find these days.

What's the install time on a mac pro 4.1 flashed to 5.1 running High Sierra and with AMD Radeon R9 270x 2GB Graphics Card? I had no issues downloading/installing mojave through the initial stages, got the apple logo etc on restart and again at what seemed 95%+ installed but then the monitor screen went blank again and the power is showing an orange light rather than green so I guess no power though to the screen.

It's been like that for 45 or 50 mins and the HDD is churning along as if something is happening. It's after 12.30am here so just about to go to bed and leave it running but I am concerned at how long it's taking. Even now and again the mp sort of signs like it's about to power down but then nothing changes on the screen.

Retina MBP took about 35 mins tops from start to finish. Any thoughts?
 
FYI
On supported Macs, 10.14.1 updates boot rom firmware and uses new numeric naming. This might have implications for boot rom on Mac Pro 5,1 with dosdude1 boot rom patch for NVMe support.

It shouldn't directly effect the boot rom on unsupported Macs but it will probably hang the post installation steps on unsupported machines.

Thanks, I tried this but there is no difference, my isight is not responding from before.
tried on MacBookPro8,1
camera
UVC Camera VendorID_1452 ProductID_34057

Did you replace /S*/L*/E*/IOUSBFamily.kext and rebuild kextcache as well? That was the previous step necessary for me. But we have different computers. I'm on a MacBook7,1 with the camera being
UVC Camera VendorID_1452 ProductID_34055. So, slightly different.
 
OK, pretty sure I'm screwed. Still no change so I restarted the MP and it start to load the OS to about half way and then the screen power to standby and I see a message 'no power'. If I can't load the screen drivers is there any way I can reinstall High Sierra from a usb drive? Tried cmd R and the same issue persists, no screen power.

"Cocoa.framework" Does this framework have anything to do with transparency? Could you find out?

I believe it is mostly handled at a high level in AppKit (a part of Cocoa, but it's in its own framework) and at a low level by OpenGL (also a framework) and the graphics drivers for your GPU (kexts). But @pkouame and others are much more knowledgeable than I am.

Nope , sorry I didn't find that comment yet
