macOS High Sierra (10.13) Unsupported Macs Thread

Hello everyone,
After installing the night shift patch through the patch updater, I am unable to enter the settings for keyboard, mouse and trackpad. Any solutions for this? Sorry if it has been asked before.

I tried to install High Sierra on my (completely supported) unsupported 2009 24" iMac through dosdude method but after making the bootable usb drive, when I try to boot it, it starts loading forever, the bar under the apple logo goes at the end but nothing happens, I tried to leave it like that for like an hour but no luck.
Tried several usb drives and usb ports always the same, what it can be?

On another thread Olivia88 discovered what caused this issue, it's an invalid patched Night Shift CoreBrightness framework, if you are on the latest 10.13.6 High Sierra version, try mine NS already patched for High Sierra following these steps:

- Open Finder then GO "go to folder" or use keyboard shortcut CMD+Shift+G and copy-paste:

/System/Library/PrivateFrameworks/CoreBrightness.framework/Versions/A/

- Replace the one inside this subfolder with this already patched binary unix exec CoreBrightness I have attached
- After done restart your iMac, this will bring Night Shift natively on unsupported Mac and mainly will fix your input devices prefpanes issues

This solution did not seem to work, unless it has to be modified for my particular model.
@jackluke ?

It should cover all the unsupported high sierra night shift models.

Try using CoreBrightness unpatched from HS 10.13.6 and see at least if fixes prefpanes input devices issues.

Try disabling SIP, then try copying a fresh version of that modified file to that same location.
Restart.
Try your preference panes.
Re-enable SIP.
Verify that the panes still will open.

The SIP was disabled all along.
So far I can get to work either night shift or prefpanes, but cannot seem to have both.
Also after manipulation with CoreBrightness replacement I noticed that the optical drive started to spin at the boot up which is never happened before.
Is there a chance that the modified file got somehow corrupted? I don't know how to check it but the text editor could not open it, while I could open unpatched file in text editor.
 
Hi, i have a Mac Pro 4.1 running High Sierra thanks to the patch, but now i would like to upgrade my firmware to 5.1 and do an Install of Mojave and Install a new video card, but cant enter recovery mode to desabe SIP. I Think i may not have the recovery partition. Any ideias ? Is this the best way to go or just Install the new patch for Mojave and Buy a new graphics card Like a Shapiere RX460 Pulse . Thanks

Scroll down to problem 2 at this link and download the refind flashdrive image: https://forums.macrumors.com/thread...nsupported-macs.1889851/page-37#post-24695866

Install it on a flash drive, boot from it, and select "disable SIP", then boot to macOS. Done.

I keep a usb flash drive with refind on it just in case SIP ever gets re-enabled. It's saved my bacon more than once.

Before installing your GPU, you need do trash your old install and do a clean one. Now you have a supported Mac.

Hi, I switched from ATI 5770 to NVIDIA 970 on my MacPro 2008 but the graphic is very slow and with glitches everywhere. I'm on High Sierra 10.13.6 with proper nvidia drivers. Tried to run the patch with no luck.
Must I remove the ATI drivers? And if yes how can I do it?
Thanks!

The best course of action is for you to install 10.13.6 again, on a empty drive, with dosdude1 patches and then you don't select the ATI patches.

Hi Tsialex, gasp you mean install from scratch? Should I install with the ATI or the NVIDIA installed? Because I cannot see the boot screen with NVIDIA. Is there a way to uninstall AMD drivers? Thanks!

Yes, dosdude1 patcher has a AMD removal patch. I never used it, but people here report success.

Ok tried the AMD removal script with no luck. Now the question is: how can I re-install High Sierra with the GTX 970 inside since I cannot see the boot screen and if I put the USB with the installer I cannot see it using the alt key at the start. Must I reinstall the ATI? (please no).

Thanks!
A.

Update: tried to install High Sierra from scratch re-installing ATI 5770. The problem is that I have to choose the AMD patch because without them I cannot run the post installation app for my Mac Pro and cannot boot at all.
Then I reboot fine in High Sierra, install the nvidia web drivers, change the GPU to GTX 970...

Same problem: I can boot, but very poor performance and many video glitches. Geekbench can't even find the GPU, Final Cut Pro X says that the GPU has no acceleration and won't open. There's must be something I dont' get.

It is very likely that in a few days Apple will release "Security Update 2018-002" for macOS High Sierra (10.13.6).

Please share your installation experience and first operating impressions on unsupported Macs.

Thanks!
 
I installed 10.13 on my MacPro 3,1 with Sapphire AMD HD7950 and noticed the following issue:
When booted into the inlogscreen, the background is bright red. The very first time it was a blurred out version of the desktop background.
Also when using Preview this same bright red background is there, sometimes temporary when the screen content is being built up, but sometimes a rectangle inside the Preview window remains bright red. I also noticed it in other windows.

Is this a known issue? I reapplied the patch for the AMD graphics in the Post Install, but that did not help.
 
The only solution seems to exchange my AMD Radeon card for an NVidia one. However, I do need the boot screen, so any recommendations? I did a search on flashing nvidia cards to get the boot screen, but did not find anything useful.
 
I doubt those cards are comparable with my HD7950. I was thinking more in the direction of a GTX1060 or similar.

You're right about the GT640 not being as powerful as your HD7950:
HD7950: https://www.videocardbenchmark.net/gpu.php?gpu=Radeon+HD+7950+/+R9+280&id=325
GT640: https://www.videocardbenchmark.net/gpu.php?gpu=GeForce+GT+640&id=1432
However, there are other Mac compatible options on eBay:
