With the macOS Sequoia 15.4 Beta, you may receive an Error 2001: Background Component Unavailable message when running iLok License Manager or protected software.
The latest beta versions of macOS 15.4 interfere with the normal operation of iLok License Manager and protected software. Apple is aware of the behavior. PACE is working on a solution that will be in place by the official final release of macOS 15.4.
This entails that all iLok products are currently not compatible with the macOS Sequoia 15.4 Beta. This applies to all UAD native software, plug-ins, LUNA and UA Connect.
We support all fully released versions of macOS. If iLok License Manager and running your protected software is important, please revert to a non-beta version of macOS. Please see the frequently asked questions section of the Apple Beta Software Program for further details on how to do that and on their beta program.
For more details from PACE, read the iLok Support Page for the latest details.
