We have received the report from users who saw MovieRecorder crashing when using the remote control feature with Catalina.
We have identified the issue, which happens in the Thumbnail generation. It happens in a code that hasn't changed since a while, and does not happen with previous versions of the OS, so it's an issue specific to macOS Catalina.
We are working on a new version of MovieRecorder (version 4.4), a pre-release version is available and we advise all users with macOS Catalina and using the remote control feature of MovieRecorder to test that version.
We'll continue working on this and will keep this article updated with our progress.
Does this issue occur if ANY Catalina system is involved or only if the Remote Mac is running Catalina ?
EG if the Remote MR software is on a Mohave Mac but the controlled Mac is on Catalina, could this issue happen?
It is only when the server is running Catalina (or Big Sur). So the answer is yes. The good news is that the client can be on Catalina with no issue.
