Problems installing Audio Unit components on High Sierra Apple Mac Pro (early 2009) Firmware 4.1 -&gt; 5.1
macOS 10.13.0 High Sierra
Logic Pro X 10.3.2


Hello, I upgraded my Apple Mac Pro to High Sierra last week. This may have been a slightly rash move for I find that whenever I have attempted to install an AU based plugin intended for use with Logic Pro X, I am having difficulties in getting Logic Pro to recognise the new plug-in. 

I know that deleting /Users/carlca/Library/Caches/AudioUnitCache/com.apple.audiounits.cache will force Logic Pro X to run AuScan, and I have also discovered that rebooting the machine just prior to installing a new plug-in sometimes helps, but it's nowhere near 100% reliable and it's a pain in the derriere. 

Does anyone know how I can fix this issue? Or has someone found a reliable way to install AU based plugins for Logic Pro X under macOS High Sierra?

I'm hoping I don't need to wait for macOS High Sierra and/or Logic Pro X to be updated.
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!
