Mac OS High Sierra- Plugins not showing up

I just spoke to a guy from support he told me to uninstall and reinstall logic. i will try it but i'm not hopeful. i have the arturia V5 bundle and it is only the prophet v3 (a personal favourite) that isn't showing. also the eighty eight 2 plugging from sonivox isn't showing, however! if you go to the components folder and vet/vst3 folder they are all installed and when opening the ilk and software centre's for these plugins. they are fully installed and licensed. i will be waiting a long time before i update to a new OS in future. and to anyone considering it i would definitely hold fire for a bit, you have been warned!

This is now happening in all the HS betas right up to #5. I doubt this is going to be addressed anytime soon. Just to be clear, it is not all .components that need a reboot in Logic X to show up, only most of them. It feels like stepping back in to the world of Windows 98. I'm going to go out on a limb here and think that maybe this won't get addressed until a Logic X point release happens if at all. One step forward and three steps back with every new release. uggg

Oh and ditto on the above with the re-scanning of some handful of plugins that I'm certain Apple will blame on 3rd parties, many whom may even be out of business or will just never update. Apple could probably fix this is some manner if they wanted to be bothered. another uggg.

Mixed blessing... rebooting the computer solved it for me... sadly that sounds very microsoft like!

I have exactly the same problem, really frustrating!

Have you tried restarting your computer after installing the plug-ins?

I’ve experienced similar issues that have been resolved when rebooting.

A minor time saver... I found logging out and back in works too. Saved me several times from a reboot. Agree on the microsoft comment, a few too many of those bugs from Apple lately.
