I have solved my issue and hope this helps others.

Initially the microphone permission patcher (MacApplication.java) with the Vanilla Minecraft launcher was resulting in an IOException, 'Exit code -1'.

It would appear the command codesign --deep --remove-signature /Applications/Minecraft.app was failing due to xcode-select being unavailable or configured incorrectly on my system.

When I tried to run codesign --deep --remove-signature /Applications/Minecraft.app from terminal I received a xcrun error. Some searching through Stack Overflow seemed to point to xcode-select as the culprit. Although xcode-select appeared to be installed and was a valid command in terminal, I didn't have Xcode installed on my system.

So to solve my patching error I took the following steps:

1. Installed Xcode from the App Store
2. Restarted MacOS
3. Launched Minecraft and this time the microphone patch was applied successfully
4. Restarted Minecraft and MacOS asked for permissions to use Microphone (selected Yes)

Presumably installing Xcode updated or resolved any issues with commands required to run the microphone permission patch.
