iPad won't sync unless I upgrade to Catalina
My iPad Air 2 is updated to iOS 13.1.3, and I for the past two days I have tried connecting it to my iMac to sync it. iTunes will not recognize my iPad any more, so I can't sync it/back it up, etc. The error message says, "A software update is required to connect to iPad." The only possible software update that can be done on my iMac is Catalina (I checked the Apple menu already to be sure). I do not want to upgrade to Catalina yet, and everything I've read online suggests that I should be able to sync my iPad even though I am still using Mojave 10.14.6. I am desperate to sync my iPad because I need to add some photos and videos, but the computer will not recognize it (i.e. the iPad icon won't even appear in iTunes). Weirdly but fortunately, my ancient iPhone 6 will still sync just fine with iTunes. Thanks for any suggestions!
