integrity cannot be verified on MacOS 10.15 Catalina

[mko]

Hi forum, first time poster here. I was going to put this in the tracker but it sent me to post here first.

FreeCAD does not run on MacOS 10.15 Catalina. I just upgraded from public beta 6 to public beta 8 and on all versions running FreeCAD produces the following message:

“FreeCAD.app” can’t be opened because its integrity cannot be verified.
This software needs to be updated. Contact the developer for more information.

I don't know what exactly changed with Catalina but I've found another developer facing the same problem with their app https://stackoverflow.com/questions/574 ... x-catalina

What does the forum think? Thanks.

Mac is simple annoying.

“FreeCAD.app” can’t be opened because its integrity cannot be verified.

Maybe this is because we haven't signed the app?

It has something to do with signing the app or what Apple calls app notarization. For now I've figured out a workaround: open terminal and run the following command to manually remove quarantine attribute:

Code: Select all

sudo xattr -d com.apple.quarantine /Applications/FreeCAD.app

Can someone confirm

I've checked this bug but I don't think it's related as the issues are rather different. I could not start FreeCAD at all before removing the quarantine flag. Catalina seems to increase security requirements for apps and FreeCAD may need to be signed or "notarized" by Apple.

10.15 is hardly used here and the solution sounds very convincing. I have added it to the known issues, although we have no confirmation yet.

Apple have used Gatekeeper for a while now to prevent applications from developers who have not gone through the App Store for their applications. This is fairly common, and not unique to Catalina (10.14 Mojave and 10.13 High Sierra also had Gatekeeper)

An additional workaround is to right-click (or control-click) the FreeCAD App, and click Open.

This is known, but it seems not to work always.

Thanks for this thread! I was not able to download freecad v19 from github, cause there is no .dmg (18.12.1019). - it was hard to find another version. - For non-proffessionals: You have to go to: https://github.com/FreeCAD/FreeCAD/releases - sroll down to version 0.18.3 (this is the latest version with a .dmg data) - click on "Assets" and there is the .dmg (Today: 18.12.2019). Install and open it the normal way, but press "ctrl" before you start (as said in the comment above). From this point, it will open normal, as usual. Why this problem appears: The Apple-Site says: The developer has to sign (https://support.apple.com/de-de/HT202491 - german). Good luck everybody
