My application takes about 20-30 minutes to s It works fine when it finally opens. I have tried to uninstall the application and reinstall with no luck. It gets on this attached picture. Wondering if anyone had recs to help resolve the prolonged start up time?
The startup time should be 20-30 seconds and not 20-30 minutes. That said, the binaries in the Slicer Preview Releases are not signed or notarized, so macOS may perform lengthy extra checks. Startup time of a Slicer Stable Release should be much faster. A slow disk and certain extensions may also delay the startup.
