Ok i managed to make it work

To make the installers work you have to open terminal and type in "cd /to/your/path" OR type in "cd " (include the space bar) and then drag the installation folder into terminal then press enter.

Install

To replace .component you have to open terminal and type "chmod -R +r " (include space) and drag the new .component file into terminal and press enter. Then type "chmod -R +x " (include space) and drag the new .component file into terminal and press enter.

Then type "sudo cp -R "(include the space) and drag the new .component file into terminal and type a space then drag the destination folder into Terminal and press enter.

Your command should now look like this:
"sudo cp -R /path/to/new/Plugin.component /Library/Audio/Plug-Ins/Components"

When you first open the plugin, MacOS will try to block it. Open Settings, Privacy & Security and scroll to the bottom to allow access.

Enjoy
