Hmm.. I have a bunch of customers who report my app is crashing after updating to macOS26
The app is compiled with Xojo2025R2.1
2 users says it is still working on another system running macOS15.
This is one of the crash reports: but the other are similar. Seems the PopupMenu is the problem (which the API changed in macOS26). We definitely need a beta that works with macOS26 before my customers are getting more upset.
