can't open DrRacket 8.5 on M1 macOS

[Kuang-Chen Lu]

Hi,

My colleague can’t open a fresh installation of DrRacket. She installed the DrRacket 8.5 Apple Silicon 64-bit version.

Her screen recording shows more details:

• After trying to open DrRacket (00:00 of the video), no window shows up
• Besides, DrRacket cannot be found in the Activity Monitor (00:08), which confirms that DrRacket is not running.
• After trying to open DrRacket again (00:15), still, no window shows up
• If you look at the Dock (the sequence of App icons at the bottom of the screen) carefully, you will notice that something shows up and then disappears immediately every time (00:02 and 00:16) DrRacket is opened. This suggests that DrRacket is closed immediately after being opened.

Thanks,
Kuang-Chen

Can you open it from the terminal:

open /Applications/Racket\ v8.5/DrRacket.app

This way any errors will be visible.

Also - was Racket moved to the Applications ?
It looks like your colleague is opening from the downloaded archive [but I could be wrong].

Thanks! I have forwarded your messages to her and will keep you and this group updated.

This is a known problem see Github issue https://github.com/racket/racket/issues/3666

Thanks, Jens Axel and Mark! My colleague says your help solve her problem. Unfortunately, we didn't figure out what exactly broke her earlier installation.

> It works now!! Thank you so much for your help! ... I'm not sure what I changed this time during installation but reading the error thread certainly helped!
