Just wanted to mention this in case you have any AIR apps on the Mac App Store or distributed to customers you want to check on if using an older captive runtime AIR SDK. It seems there is a consistent crash happening on OS X El Capitan 10.11 with File.browseForOpen on one of my AIR apps distributed in the Mac App Store. The app is currently distributed with an older AIR SDK (3.8), and never needed updating as it has worked perfectly fine all recent OS X updates, including 10.10. However, now in 10.11 El Capitan, any attempt to use File.browseForOpen in the app crashes the app (with the crash info at the bottom of this message.) I just tested rebuilding and rerunning the app with the latest AIR SDK 19 (albeit not in the app store sandbox environment) and it works fine in El Capitan so I guess an app store update is in order to avoid the crash. Just wanted to mention this in case you want to check your OS X AIR apps, or does anyone know about this specific issue of a Save or Open Panel not running on the main thread that was fixed/changed in a recent AIR SDK that I just happened to miss? Or does anyone know if this is a new assertion with El Capitan?
