H All,
I'm hoping you can help me, as you did earlier with a similar problem.
iMac 9,1 early 2009 formatted APFS
Have been running Mojave successfully, with full keyboard brightness control, after using DosDude's patcher, and your instructions to install the BkltPatch 10.14.2 (I'm not exactly a pro at using Terminal, and you really helped by giving me step by step instructions on installing BkltPatch a year or so ago).
Anyway, after installing Security update "macOS 10.14.6 Supplemental Update", along with "Security Update 2020-005," (via Software Update control panel, and then running DosDude's Mojave post install, forced rebuild, and patch installs, it appeared to update successfully. About this Mac System info says: macOS 10.14.6 (18G6032)
However, I lost the use of my keyboard to control the brightness. Pushing the keyboard "up" or "down" brightness button does work, but only momentarily.
So, I followed your earlier instructions to use Terminal to install BkltPatch 10.14.2, but that did not work after several attempts.
Do you have some suggestions for how I can get my brightness buttons to work again, and if so, would you please explain in simple terms since I am basically a novice at Terminal?
Thanks so much!
Bill
