Description of issue

When installing GPXSee cask, the following message is displayed, even on Intel Macs:
gpxsee is built for Intel macOS and so requires Rosetta 2 to be installed.
Additionally the installed app cannot be started with MacOS complaining that it can't check it for malicious software.

When installed with the --no-quarantine option it runs normally (at least on Intel Mac).

The message about Rosetta is a caveat. It is displayed regardless of your architecture.

The other issue you are seeing is macOS' Gatekeeper warning you that the application is not properly signed. This is not a Homebrew issue. The authors of GPXSee need to correctly sign their macOS releases to prevent this.

TLDR: use MacPorts instead of Homebrew

The "GPXSee on macOS" situation is sad but reflects the user interest. As there is no real user interest (no one is willing to pay for Apple HW or the Apple "racketeering" fee for the certificates) there is no official ARM/Apple signed build of GPXSee. The situation in Homebrew is the same - there is no interest to provide at least an ARM build to the users. So all you can get for free at the moment is the MacPorts build which is also recommended on the GPXSee homepage. You may also use the GPXSee Qt6 CI build that is compiled for both Intel and ARM, but nothing will be signed by Apple.

Regardless of your feelings on the matter, applications will eventually need to be signed to work on macOS. So if you're going to take a hard line here, you should be ready to drop support for the OS entirely.

I'm definitely ready. The day Apple decides what you can run on your computer not you, will be the last day of GPXSee for macOS. But while the screws are tightened every year by Apple, they had not yet the courage to close the macOS ecosystem like they did with iOS and the only reason is, there are still enough applications like GPXSee that refuse to submit to Apple...
