macOS Catalina, the next Mac release, dramatically tightens security and removes 32-bit compatibility. That will cause incompatibilities with music software, requiring updates. Here’s what you need to know
Catalina compatibility checklist
macOS Catalina (10.15) is expected to ship in October, replacing Mojave (10.14).
What’s impacted:
DAWs and other software using plug-ins: Requires updates to work.
Drivers: Installation and operation requires update to work.
32-bit software, software that accesses 32-bit libraries: Incompatible. Cannot be used past macOS Mojave.
Software using legacy video libraries: Incompatible. Cannot be used past macOS Mojave.
Plug-ins: May require update for full compatibility – but may run inside updated DAWs, and will install if the user overrides OS’ installer requirements.
Hardware: If a driver is required for operation, you’ll need an updated driver and installer. Driverless (class-compliant) audio and MIDI gear is unaffected.
This is the whole report of what is happening with the Catalina upgrade
CDM Report I would suspect most software company's will have their updates very soon so just hang in there, no worries! Besides Catalina has not been released as of this post, though it will be sometime this month.
