Hello @Andy 1977 ,
.NET MAUI apps that target Mac Catalyst can only be launched and debugged using Visual Studio 2022 for Mac. For more details, you can refer to Build your first .NET MAUI app - .NET MAUI | Microsoft Learn
As you said, pairing to Mac is for iOS development (not macOS) and it can access to Apple's build tools. For more details, you can refer to Pair to Mac for iOS development - .NET MAUI | Microsoft Learn
Best Regards,
Wenyan Zhang
