I cannot play Apple TV+ in a Safari browser window on my 2019 27" Retina iMac with Mojave without supplying a credit card, not a debit card, number for verification. Sure I could move to Catalina and use the Apple TV app for the Mac. However, I don't want to move to Catalina until some of the compatibility issues with older software has been resolved. I have several other ways of watching Apple TV+ such as on my iPhone, iPad, and/or Apple TV 4K. It would be nice, however, to be able to watch it on my iMac. But until I move to Catalina I can't watch Apple TV+ on my iMac. With everything else offered by Apple that requires a payment type, PayPal is acceptable but not for Apple TV+. This situation is extremely irritating.
