Spyder doesn't open any windows on macOS Monterey

[Mark Diekhans]

I installed Spyder using the macOS installer available from the
download page. It is not completely clear what version this is
download, as it has a comment about "4.2.1, scheduled for
release on December 18, 2020.", but it appears to be 5.3.1.

Spyder starts, bounces a bit in the doc and then is running:

USER PID PPID NI RSS VSZ %CPU %MEM STAT PAGEIN ELAPSED COMMAND
markd 22036 1 0 12540 34873136 0.0 0.0 S 0 28:14 /Applications/Spyder.app/Contents/MacOS/Spyder

However, no window is ever open. This happens on both Intel and M1 system.

Logging in as a vanilla user, and it starts. Starting it from
the command line using open -a and a cleaned out environment and
it still doesn't start.

Any ideas on what would cause this?
thank you!

Hi,

Our Mac app only works on Catalina (10.15) or above. If you're using it
in older versions, it'll simply crash.


Cheers,
Carlos

thanks, this is Monterey. There is something in my user environment,
on two computers that is causing the failure to open. I have yet
to determine what it is.

Monterey (macOS 12) is the newest macOS. You may be thinking of Mojave (macOS 10.14)?
