I did not say XCode. The official Apple support for OS 10.13 ends in January 2021 and TurboTax will not support any OS not currently supported by the OS manufacture (by current I mean the entire 2021 tax year). I am sure that is a Intuit business decision. It has been the policy for years and I do not think it will change anytime soon. This question comes up every year - last year it was OS 10.12 that was dropped and next year 10.14 will be dropped.
Management simply does not believe there is sufficient customer base to justify maintaining software for outdated OS's. Windows desktop still dominates the US market and the old Mac market is shrinking every day.
Personally I will be in the same position next year, while I can upgrade to 10.14, it does not support 32 bit apps. I have a 32 but app that I use all the time there there is no replacement for it and the vendor is out of business.
