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 William Prothero https://earthlearningsolutions.org > On May 15, 2020, at 9:04 AM, Graham Samuel via use-livecode > <use-livecode@lists.runrev.com> wrote: > > As many of you will know, I have been struggling to create an iPhone app - > very unfamiliar territory for me.
