@pixel01 See, if this changelog entry in the latest Release Candidate, RC-3 solves the freeze while framing on MacOS:
It will install as a separate “PreRelease” version of LightBurn, which has it’s own set of preferences. This means it will not affect your standard installation of LightBurn at all.
The installer should automatically ask if you want to import a copy of your standard release version preferences - you can also use the User Bundles feature to move over your preferences.
