WoS does not show up in Logic - AU validation issue after WoS update

After installing Wall of Sound for Logic (AU format), it may not show up in the list of plugins. Logic often needs to do a validation.
Here are the different steps as given by Apple to solve the issue.

Restart your Mac

If your Mac is running macOS High Sierra or later and you recently installed a plug-in that isn't available in Logic Pro or MainStage, restart your Mac. Before you restart your Mac, confirm that the plug-in is 64-bit compatible. 32-bit plug-ins aren't compatible with Logic Pro or MainStage.

•     Choose Apple menu > Restart.
•     Open Logic Pro or MainStage.
•     Click an Audio Effect, Instrument, or MIDI Effect slot to see if the plug-in is available in the pop-up menu. If the plug-in still isn't available, rescan the plug-in.

Confirm that the plug-in is installed

If a recently-installed plug-in still isn't available after restarting your Mac, confirm that the plug-in is installed:

•     Choose Logic Pro X > Preferences > Plug-in Manager, or MainStage 3 > Preferences > Plug-in Manager.
•     In the Plug-in Manager, locate the plug-in. To filter the list by manufacturer, click the manufacturer's name in the left column. For the Wall of SOund, the manufacturer is Two notes Audio Engineering.
•     If the plug-in doesn't appear in the Plug-In Manager, uninstall the plugin.
•     Go to Machintosh HD/Library/Audio/Plug-Ins/Components/ and trash the file "Torpedo Wall Of Sound.component"
• Launch logic without any WoS installed
• Reinstall the latest WoS

Rescan a plug-in

If the recently-installed plug-in is installed, use the Plug-in Manager to rescan the plug-in.

•     Choose Logic Pro X > Preferences > Plug-In Manager, or MainStage 3 > Preferences > Plug-In Manager.
•     In the plug-in Manager, locate the WoS plug-in you want to check. To filter by manufacturer, click Two notes Audio Engineering in the left column.
•     If "failed validation" appears in the Compatibility column for the plug-in, select the WoS plug-in in the list, then click Reset & Rescan Selection.

   
   
Rescan all plug-ins

To automatically rescan all installed plug-ins, remove the Audio Unit cache file.

•     In the Finder, press Option and choose Go > Library.
•     In the Finder window, go to Library/Caches/AudioUnitCache.
•     Move the files from AudioUnitCache folder to the Desktop.
•     Restart the computer, then open Logic Pro X or MainStage. All installed Audio Units plug-ins will be rescanned.
