Problems installing Audio Unit components on High Sierra

Solution 1:

Actually, I have made progress with my setup. The trick seems to be to be disciplined enough to carry out the installations, then deleting /Users/[USER]/Library/Caches/AudioUnitCache/com.apple.audiounits.cache, then rebooting, before finally opening Logic Pro X again, at which point it should rescan all the new plugins. It's a fiddly procedure but it seems to work!

Solution 2:

Good news, I think! I've just installed the newly released 10.13.1 High Sierra update. I then high-tailed it over to KVRAudio and downloaded an AU plugin (Sprike, since you ask - it's pretty good!). I was able to install it and then run Logic Pro X without any deleting of files or rebooting malarky. It just worked.
