DeBleeder Terminal Commands Protools
The following instructions are using the terminal in OSX for dealing with the security issues introduced in Mojave and Catalina. To run them goto your application folder and than into the utilities folder, in there you will see the program called terminal, launch that. These instructions assume you have already placed the files in the appropriate directory using the finder. This FAQ https://wilkinsonaudio.com/pages/debleeder-faq describes at the bottom how in the finders do you make it so it reveals hidden folders.
Once the aax files are moved to the /Library/Application\ Support/Avid/Audio/Plug-Ins folder these commands can than be used.
Copy and paste each line one at time into the terminal and hit return after pasting it in
cd /Library/Application\ Support/Avid/Audio/Plug-Ins
You should see the 3 files DeBleeder_Stereo.aaxplugin, DeBleeder_Mono.aaxplugin, and DeBleeder.aaxplugin displayed as an output. If they are not there you have placed it in the wrong place. Remember there are actually 2 libraries one under the username and one under the main hard drive name, you want to have it under the main hard drive name. Probably these files will have an attribute called com.apple.quarantine showing on them. This attribute needs to be removed from all the files. The following command does that.
If you see the attribute com.apple.quarantine on the debleeder plugs-in the following command will remove it
xattr -d com.apple.quarantine DeBleeder_Stereo.aaxplugin DeBleeder_Mono.aaxplugin DeBleeder.aaxplugin
You should see the 3 aaxplugin files are still there but they should no longer have the com.apple.quarantine flag on them.
Start Protools up and DeBleeder should be there.
For those not familiar with the use of the terminal this video should be of help. May put you to sleep but covers the use of the terminal and these commands.
