I’m getting a warning that Site Designer will not be working with the upcoming macOS 27.
I have the latest version of Site Designer5.1.3626
I'm using a Mac Studio M2 Max.
Anyone else seen this?

I may be a little grumpy in the morning, that is, before my first cup of coffee ;)

MacOS 27 will only support apps that fully run on Apple silicon (their chips).Currently, SD is not quite there. I asked and CC is aware of it and already planning/working on the changes needed to be able to run SD on macOS 27.

Did you know that Web Form Builder can be used for both simple and complicated forms and that it's not limited to the default fonts and buttons? Take a look at a form we developed for WindowTinting.com.
