When I searched for the app in the App store it stated that the app was not compatible with this device
O.k, so it's not compatible. There's nothing much to do if it's not compatible.
If its not compatible, then it cannot be installed on a Mac.
Just because there are versions of iPad and iPhone does not mean there's a compatible version for Mac.
The developer would need to make a Mac specific version, or if you are using an Apple silicon Mac, allow the iPad version to run on a Mac, for some reason they have chosen not to do so.
Contact the developers of Signal and tell them you would like a Mac version.
I have loaded the messaging app "Signal" on my iPhone and iPad but can't seem to load it on my MacBook Air. Any suggestions?
