Upgrading iMac 8.1 from Mac OS High Sierra 10.13.6 to Mojave 10.14.3 successfully...
Well, almost...
To run the WiFi under 10.13.6, I had replaced the famous Broadcom BCM4321 with an Atheros AR5BXB92 (worked very well under 10.13.6 ...) and to my surprise it does not work anymore with Mojave!!!
I fixed this automatically with the tool "AirPortAtheros40 installer.app" on this page:

here is the direct link, if someone is interressed: (an account must be created in order to download...)

This application install the missing AirPortAtheros40.kext into /System/Library/Extensions, repairs authorization on /System/Library/Extensions and rebuilds system caches.
Now the Wifi of my iMac 8.1 works perfectly.
I have a question for Dosdude1: What exactly does "Legacy Wifi Patch" in the "macOS Post Install" application?
Only brightness no longer varies with the F1/F2 keys or system preferences. I installed "Brightness Slider" but it does not satisfy me. Is there a way to reactivate the F1/F2 keys for brightness?
or is there a post that explains how to solve this? I have a little fleme to reread the 467 posts...

Hello everyone,
Having no answer to my questions, I just reread 447 pages and I just saw Dosdude post #11156 regarding backlight control for the CCFL-based display systems. I make the fix as soon as possible.
