Verify LibreCAD file on MacBook

I want to install the free Librecad software on my Macbook Air.

I found the download link on GitHub via Librecad.org. I then downloaded a .dmg file. When extracting/installing, I keep getting the message that the source cannot be verified. Can someone tell me how to solve this or perhaps recommend another source that can be verified?

Maybe this could help?

I am sorry, but this method is not the solution to my problem.

From AI on my phone:
The "unverified developer" warning is normal for LibreCAD because it's an open-source project and not signed by Apple.  The software is safe and can be installed by bypassing macOS Gatekeeper. Here's how:

How to Fix the "Unverified Developer" Error
Try to open LibreCAD from your Applications folder — it will fail and show the warning.
Go to System Settings > Privacy & Security.
Scroll down and look for a message like:
"LibreCAD was blocked from opening because it is not from an identified developer."
Click Open Anyway.
Return to Applications and try opening LibreCAD again — this time, click Open in the confirmation dialog.
This is a one-time process. After approval, LibreCAD will launch normally.

🔐 Note: LibreCAD is safe. The warning appears because Apple requires paid developer certificates to sign apps — many open-source projects, including LibreCAD, don't pay for this.

I suppose you are running Apple Silicon (m5, etc.). Please try the fix mentioned in:

xattr -rc LibreCAD.app
sudo codesign --force --deep --sign - LibreCAD.app
