Using 9.6.0 DP4, I compressed (.zip) a Mac application and uploaded it to Dropbox as I usually do. When the zip file is then downloaded and unzipped by a user, the application reports an "application is damaged and can't be opened" error. This just started happening with 9.6.0 DP4. It's ok with 9.5.1. I think it has something to do with code signing. Does this mean we may no longer be able to distribute zipped Mac apps as of 9.6.0 ?



thanks,

Apps now need to be notarized in addition to code-signed. If you recently updated to Catalina then that's why you're getting this message. Mojave was more lenient.

Thanks Jacque,

I figured it had something to do with that. I didn't update my OS. In fact, I'm still using High Sierra on an older 17" Macbook Pro, which unfortunately can't be updated to Catalina. I guess I'll be forced to update my computer if I want to continue coding. I really liked the 17" screen....

If you're still on High Sierra then I don't think that's the problem, High Sierra doesn't care about notarization. I'm not actually sure what's wrong, TBH. Maybe you just need a new distribution or development certificate.

If you do plan to send out the app to others running Catalina then you'll need to notarize it anyway, but you should be able to do that without updating your OS.

Hello all,

Indeed, you need to notarize your apps if you plan to distribute them outside the Mac App Store.

However, a non-notarised app should show a different warning dialog, and you should be able to open it by right-click -> Open.

The error dialog that you are getting is because of a bug in LC 9.6 DP-4 (https://quality.livecode.com/show_bug.cgi?id=22702), which is fixed in LiveCode 9.6.0 RC-1 that was released today.

Kind regards,
Panos
