OS X Catalina

[John Hegarty]

Seems to be a compatibility/permissions issue with the recently released OS X Catalina. When I set it in the security settings to ”Open Anyway” it doesn’t load. It bounces once in the Dock and stops - no error message.

Thanks for letting me know. I think the issue is that MicroBlocks is currently compiled as a 32-bit app and 32-bit apps are no longer supported on Catalina. Will fix.

Same issue here wit maOS 10.15 Catalina.

Launching MicroBlocks manually from the Terminal, now with zsh.

% ~/Downloads/MicroBlocks.app/Contents/MacOS/MicroBlocks

returns an error about Bad CPU type in executable.

zsh: bad CPU type in executable: ~/Downloads/MicroBlocks.app/Contents/MacOS/MicroBlocks

Same with legacy sh.

sh-3.2$ ~/Downloads/MicroBlocks.app/Contents/MacOS/MicroBlocks

sh: ~/Downloads/MicroBlocks.app/Contents/MacOS/MicroBlocks: Bad CPU type in executable

Not sure what Bad CPU type in executable means.

Thanks for the report! That error message is another symptom Catalina no longer supporting 32-bit apps. I’m making progress on upgrading MicroBlocks to 64-bit. Stay tuned for a fix soon, hopefully in the next week.

John H. reports that this is fixed in the new release, 0.2.5. (Note: He also says the security features are more aggressive and try to get you to delete the app. However, if you persist then they will eventually allow you to accept and run the app.)

Closing as this has now been resolved
