It's worth noting that the DMG is not empty:

Just tested it with the Tauri Beta, and the same issue occurs.

That's peculiar. I'll check on my MacBook later or this weekend. I know I had to do some stuff because Apple updated some terms for the apps to sign again.

Just checked and I can open both the Tauri version and the Electron version's dmg's on my Macbook Pro M3. I will try to find another user to test to ensure its nothing to do with development keys

[sekwah41]

for reference this is what i get when I run hdiutil verify -verbose

Could you send checksums of the files you downloaded?
e.g. shasum -a 256 Pomatez_1.7.0_universal-mac-tauri-beta.dmg and show me the numbers?

they should match with these if your download isnt corrupted

[sekwah41]

Can I check if this is a personal machine or a work laptop? I am not familiar with mac in enterprise but there is a chance it could be the mobile device management software you have blocking the opening of unapproved dmg's.

The logs you have don't seem to say they are corrupted vs its not found any it can mount as they all say verified.

[sekwah41]

The fact that both fail further makes me believe it's a device management issue. If you are on a work or education machine you'll have to ask whoever is managing it to authorise my app id or dev certificate. (Not sure which it would be)
