In my opinion, a number of people in these threads are missing the point when they suggest: "You can easily run these programs if you just do these quick tricks like using the command line or removing an xattr from the file or a special click workflow" There are companies out there making software for normal people (ie non technical) who will think your app is broken if double clicking doesn't work. These people will call your support lines and this will cost your company money

Two months? So Catalina will start breaking apps for average users after only two months? It hardly seems worth it for Apple to have that short of a delay.

beta

I think you answered your own question there.

People have to stop treating betas like gospel.

I've always viewed a beta as a way to test that my app has not regressed. If it has, I open issues with Apple (or whomever). If these issues are either cited as not-to-be-fixed or I hear nothing back, I will create a release of my apps that works around whatever issues are there. IMO determining breaking changes in beta versions allows one to develop fixes as well as create and plan the rollout of the new software before the beta goes lives (and therefore avoid any regression/downtime).
