Sad truth about iOS apps

Graham,
You may be able to find a used Mac that will run Catalina. My old MacBook Pro was one of the earliest that had 64 bit processor, but when it’s battery started interfering with the trackpad, I panicked and bought a new MacBook Pro. Then I took my old MacBook Pro to be fixed and it returned looking like new and working perfectly. So, I set it up for my wife, who had an even older Mac. Anyway, my new MacBook Pro is way faster and is a joy to use. I did have to buy a number of adapters to get my older usb devices to work.

I get this in a Google search.

“Apple advises that macOS Catalina will run on the following Macs: MacBook models from early 2015 or later. MacBook Air models from mid-2012 or later. MacBook Promodels from mid-2012 or later.”

Good luck,
Bill

Without help from this list and the mother ship I would have been dead in the water long ago. Finally I can see the (beta version of) the app running on my iPhones - yipee! The next step is to get it out there via TestFlight so that a few friends can mess with it.
