Help Loading In Plug-Ins that macOS cannot verify

Hi,

I've added some 3rd party plug-ins to Logic Pro X recently, (on my new MacBook Pro 16", I9, 32G RAM), and while the 'name brands' plug-ins loaded easily and properly, some of the 'lesser known names' (or not easily identified by Apple) plug-ins have come up short. The downloads went fine, and (as their instructions said for the different remaining plug-ins), I moved the "Component" file from each new plug-in to the proper folder "Computer - Macintosh HD - Library - Audio - Plug-Ins - Components". Yes, they're ALL "AU" files. And as I said, Logic upon each new startup, loaded the other new plug-ins, yet about a dozen constantly read that they can't be opened (PLEASE SEE ATTACHED SCREENSHOT FOR DETAILS). They are from legit sites and are well known plug-ins. I've reopened Logic and each time, it omits these dozen (I copied one in the Screenshot but they all read the same thing).

Please help. Thanks!

I think Iaamusic referred to this:

Safely open apps on your Mac - Apple Support.

Be warned. This message usually means an error from the developper. Personally I never install/use not properly signed software.

Thank you All!

The plug-ins being rejected are:

Some are older, many are new. Admittedly, not sure how the older dates may be bad or not useful.

They include: LePou (I believe is a known brand from a known company, a Link is: https://vst4free.com/dev/258/). (I know the link says VST, but that's just the link, I ONLY selected & DL the "AU" files for Mac. Some are from https://masters-of-music.com/list-of-best-free-and-paid-guitar-amp-sims/. And some are from https://thehomerecordings.com/free-guitar-vst-plugins/, https://thehomerecordings.com/free-guitar-vst-plugins/, others, as well as Amplifikation Lite (from their site https://www.kuassa.com/downloads/).

Again many of these plug-ins are by known companies, so just relaying to Wilddrums and laamusic (as you mentioned regarding trusting the site/plug-ins and being valid, and "not properly signed software". (Unless I'm missing something and shouldn't), I feel pretty confident about those plug-ins and companies.

So assuming it is an okay move to follow what Wilddrums and laamusic said (in the link https://support.apple.com/en-us/HT202491). Do you guys agree!?

Many thanks (especially as I'm a brand new Mac user)!

The name or reputation of the manufacturer as nothing to do with that. Either the plugin is not properly signed with a valid certificate, the certificate itself expired or the plugin is compromised. You may be in the last two categories.

First go to the plugin manufacturers for updates or fixes.

As I said I never install or use not properly signed software. Even if you can work around the macOS security.

If you’re absolutely sure that they are valid and you trust the developer and of course they are legal, you could read this and decide how to progress.
