So even if you try to install the latest version 1.0.8 on macOS, it tells you that it won't install it? I'm not a macOS user, but for this project I bought a MacBook M1 and built the app and tested it on it. Thanks to the notarization, the application was installed without any problems. But maybe I missed something. But there will probably be a problem if you report it. By the way, did you download the correct version for your Mac? For M1/M2/M3 processors you need to download the arm64 version, for Macs with an Intel processor you need to download the x64 version.
PS: publishing the application to the AppStore didn't seem easy and unfortunately I didn't have time to go through the whole process. I will try to get it done by the end of the year.
