After installing the "PreSonus Universal Control" and restarting the Mac (a MacBook Pro 15" mid-2014), the Revelator does not show up in "Universal Control".

The sound system preferences show "Revelator — USB" in the list, but not the other two "Loopback 1" and "Loopback 2". 

Worth mentioning: the hard drive is formatted in APFS-case sensitive (I hope that this is not an issue because I won't be able to change that).

After registering the Revelator, it is finally working.

As I feared, this is due to my file system being case sensitive. However, this is "easily" fixable:

  1. Open /Library/LaunchDaemons/com.presonus.ucdaemon.plist
  2. On line 9, change "/Library/Application Support/Presonus/universalcontrol/ucdaemon.bundle/Contents/MacOS/ucdaemon" to "/Library/Application Support/PreSonus/universalcontrol/ucdaemon.bundle/Contents/MacOS/ucdaemon" (that's right, the lowercase "S" is why Launchd cannot find the "ucdaemon" (the universal control background task).
  3. Save and close (you need admin privileges)
I therefore urge PreSonus developers to fix this and in the future, to try out their software on case sensitive file systems.

While this "fix" works on macOS Catalina, it doesn't on Big Sur. The Revelator appears in Universal Control, but the configuration panel does not open.

Thus it seems like that Universal Control is not compatible yet with macOS Big Sur for configuring the Revelator.
