I'm getting "Mémoires is damaged and can’t be opened" error.
This means that you're trying to run an older version of Mémoires on a newer macOS version.
Unfortunately, older versions of Mémoires don’t work when running on newer macOS versions due to changes to the app signing and notarization service on Apple’s side. We currently actively support only version 5 of the program, which works with newer macOS versions.
To solve the issue, upgrade to Mémoires 5.
We always recommend using the latest version of the program if you upgrade your macOS version.
Please note that if you have a license for an older version (1.x, 2.x, 3.x, 4.x), but not the newer version
(5.x), you'll need to purchase a new license, otherwise it will work in the trial mode.
