Its been a few weeks now that the betas of Apple's newest operating system, High Sierra/macOS 10.13, have been in the wild. And as I've been warning every Summer for a few years now: Unless the documentation or description of an application or script from this site specifically states that it is compatible with High Sierra, it most likely isn't.
That doesn't mean that apps and scripts won't work at all. It just means to watch out because they might not work as expected.
And if you're part of the Beta program and you run into an issue with an app or script you use regularly, please be sure to let me know.
