ok, but which app are you referencing when you say "We will tell our app users that Tahoe is not supported at the moment so if they find bugs on Tahoe we will not support it."There are hundreds of apps since Cheetah that skipped direct support of the newest macOS. Some apps like Scrivener have only had a couple of major app and UI updates in the last 20 years with minor bug fixes in between.
lots of apps don't actually need updates to run on a newer OS, but app users should be supported if there are issues. no?
