Dear TurboTax product manager,
I have been using TurboTax for many many years. Each and every single year, I bought your software from Costco. I enjoy using your product. Unfortunately this seems to come to an end for the next year because I was told that I must upgrade my Macbook pro to the next MaxOS version. I cannot offer doing so because I have many existing apps and softwares that will stop working once I do the upgrade. Please kindly take this into consideration.
Thanks

you may not have any luck. many windows 7 DESKTOP users were forced to upgrade to Windows 8 as a minimum. Win 7 was okay for the online version.
the same will probably be true for MAC's. the DESKTOP app will need an OS upgrade while the online version won't
You have very few options other than utilizing a dual-boot setup or buying a cheap Windows 10 laptop.
