After installing High Sierra today, I made a Flash Drive USB install disk , like I normally have with all the previous macOS releases on my 2011 21.5" iMac. This time I used the app Install Disk Creator: https://macdaddy.io/install-disk-creator/
I then booted to the USB drive to check and make sure everything worked. The USB booted, and then I ran into a problem. The 2011 iMac was not able to find my Apple Wireless Keyboard (2AA version; A1314) or my Magic Trackpad 1 (A1339.) Even trying to put the devices into pair mode (holding the power button until the green light flashed) didn't work. The only way I was able to proceed with the install process was to hook up a generic USB wired keyboard and mouse.
Anyway, I thought it was odd, and have never had an installer forget my keyboard and trackpad before. I didn't actually start the install process as this was just a test to see if I had correctly made the boot USB installer. When I rebooted into my external SSD thunderbolt drive with High Sierra, there was no issues recognizing the keyboard or trackpad.
As an additional test, I then booted into recovery software (Command R upon powering up) and the keyboard/trackpad worked normally there.
It looks like the only time the computer forgot it's keyboard/trackpad (and would not find them) is if I use the USB install drive I created.
I was wondering if anyone else had tried to create an install USB, and if they had the same issues with bluetooth keyboard/trackpad as me? I wonder if it is because I am using bluetooth 2.1 rather than the bluetooth 4.0 that is in new iMacs?
