iPhone 8 won't connect to iTunes after iOS update
My iPhone 8 Plus just updated and now won't connect to my iTunes which I need for work. The dialogue box says "A Software Update is Required to Connect to iPhone" and gives me the option to download and install immediately but doesn't say exactly what I'll be installing and whether it will affect my whole system or just iTunes. Catalina and Big Sur have caused issues with software I use for my profession and I'd hate to lose my work by accidentally updating iOS. Can anyone at Apple verify?
