macOS 10.15 Catalina - not yet supported with Serato Pitch 'n Time Pro or Serato Pitch 'n Time LE

macOS 10.15 Catalina is currently in BETA, and is not yet supported for use with Serato Pitch 'n Time Pro or LE.

We strongly recommend you do not update

We are currently testing the plug-in(s) against BETA builds of macOS 10.15 Catalina.
It's also worth noting that Pitch 'n Time Pro & LE operating system support is dictated by the supported DAW that are you using, and it's own operating system support.

It may be worth disabling automatic updates, to avoid potentially clicking the "Install update" button in the macOS pop-up notification, via System Preferences --> App Store --> Automatically check for updates (uncheck)
