Question

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).

Answer 1

After registering the Revelator, it is finally working.

Answer 2

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.

Answer 3

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.

Answer 4

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