No Preferences Window after upgrade 3 to 4

[Stevescat]

OS 10.9.5

Upgraded to Alfred 4 with new Powerpack key. Alfred starts OK, but opening preferences from the bowler hat does nothing.

When quiting preferences I get a crash report.

If anyone can shed some light on what's happening, I would be most grateful.

@Stevescat It looks like you're using macOS 10.9.

 

Alfred 4's minimum requirement is 10.10 to allow him to use some of the more modern macOS features such as Dark Mode, but we recommend 10.11+ for the best experience.

 

I've added a note to give an error message on startup if using 10.9.

Thanks Andrew, I did wonder if the OS was the problem.
