It looks like the most recent versions of CalChart that I’ve been producing have a problem that when you open them you get popup that says:

“CalChart” is damaged and can’t be opened. You should eject the disk image.

Now previously with v3.6.8 this would say:

“CalChart” cannot be opened because the developer cannot be verified.

I’m currenlty working with the assumption that with v3.7.0 I updated the version of the OS I built with. After reading a couple of docs:

• https://eclecticlight.co/2023/03/13/ventura-has-changed-app-quarantine-with-a-new-xattr/
• https://www.reddit.com/r/macsysadmin/comments/13vu7f3/app_is_damaged_and_cant_be_opened_error_on_ventura/
• https://discussions.apple.com/thread/3145071?sortBy=best
• https://github.com/Ecks1337/RyuSAK/issues/34

I learned about the xattr command. If I were to run:

xattr -rc  /Applications/CalChart-3.7.0.app 

this fixes things, but it leaves a bad taste in my mouth.

What I’m wondering is why the issue moved from “trust” this developer to “it’s broken.”

The way I see it, I have two options:

• Figure out what the problem is so the old workaround of “trust this developer” is something that people need to do.
• Set up a developer profile.

I’m going to start investigate what it takes to do development the right way.
