Tried to install the backlight control patch on an iMac 8,1. After rebooting, the OS generated a KP. Result was the same under 10.14.4, beta 5 and 10.14.5, beta 1.
Copy of the messages in the terminal window is attached, but there is no clear indication where the problem lies. Should command be executed as root?
The iMac dual boots into Mojave and El Capitan, the most recent OS version.
On the positive side, the restore from Time Machine worked without problems.
Hello
@iMac-Oldschool
I also have an iMac 8.1 and I had problems with the backlight control and F1 and F2 keys that did not work see message
#15087 but I found the solution:
on iMac 8,1 you should not replaced 3 files otherwise KP
but
only replace the file "DisplayServices.framework" contained in "bkltpatch10.14.2" in /S/L/ PrivateFrameworks (and repaired the permissions) see message
#15299.
If you did the installation of the patch with "install.sh" it made a Backup of 4 files in ~/Bklt_Backup
Restarts on an external disk and put back in place:
"AppleBacklight.kext" and "AppleBacklightExpert.kext" in/System/Library/Extensions/
"AGDCBacklightControl.kext" in /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/
And repair permissions with Terminal from the external drive:
sudo chmod -R 755 /Volumes/
NameOfYourMojaveDisk/System/Library/Extensions/AppleBacklight.kext
sudo chown -R 0:0 /Volumes/
NameOfYourMojaveDisk/System/Library/Extensions/AppleBacklight.kext
sudo chmod -R 755 /Volumes/
NameOfYourMojaveDisk/System/Library/Extensions/AppleBacklightExpert.kext
sudo chown -R 0:0 /Volumes/
NameOfYourMojaveDisk/System/Library/Extensions/AppleBacklightExpert.kext
sudo chmod -R 755 /Volumes/
NameOfYourMojaveDisk/System/Library/Extensions/AppleGraphicsControl.kext
sudo chown -R 0:0 /Volumes/
NameOfYourMojaveDisk/System/Library/Extensions/AppleGraphicsControl.kext
Otherwise you reinstall Mojave from a USB stick and you execute "install.sh" of the .zip file that I attached.
CAUTION USE ONLY ON iMAC 8,1
As you restore with time machine you must be able to start with Mojave isn't it? run "install.sh" from the .zip file that I attached.
