Oh god, I can't do this anymore 😂
Apple has been so hard on third-party apps. It's a cat-and-mouse game.
Thanks for notifying. I will take a look. I haven't updated to the latest version, but I am already on Tahoe 26.1

I found a workaround! https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unknown-developer-mh40616/mac You have to go to system settings > privacy and security > OneFolder and click the open anyway button which is active for an hour after you try to open the app. Once you have clicked on the button, the security permission for the app is retained, so it's a one time thing.

I was facing the same issue on MacOS Sequoia 15.2 and the instructions from @macbikegeek helped. Thanks!

On a related note (I think), even if we somehow open the app on MacOS, it looks like some permissions are not asked for and the "Reveal in File Browser" option does not work for images. It leads to the Finder app becoming unresponsive.

@macbikegeek thanks for the workaround!

@architchandra I will take a look. But this is a common issue we have had for a long time
