I have successfully built an app using Mac Catalyst. It runs on iPhone, iPad, and M1 Macs, and is available now in the App Store as "Designed for iPad". So far, so good.
But it's not available for Intel-based Macs, and I haven't been able to build a version that will run on Intel.
Is this possible? If so, how do I do it? And with regard to the App Store, if I do it can I update my existing app to include the Intel-capable version, or does that have to be a separate purchase?
I've been through all the Apple and third-party doc I can find, but couldn't find anything useful. Grateful for any advice!
