Thanks to sterling help from @meyumeapps we’ve located the cause of the issue which seems to be something to do with the macOS color chooser. If you have a custom color picker pane installed you might want to try moving it out of ~/Library/ColorPickers to see if that makes a difference.
We had an engineer get the latest beta installed today and the simulator seems to run fine. We will need screen shots and a better description of any errors/what you’re seeing.
unfortunately the message doesn’t appear any more, the app dies 1 seconds after launching it. I’ve tried the latest public and several of the last daily builds. Always the same behaviour.
The message seemed like it was coming from the app rather than from OSX, simply stating that 10.13 wasn’t supported but I can try and go ahead.
Does it work if you dismiss that dialog? We don’t formally support 10.13 yet, so that message is expected, but our internal testing shows that it should work. The only issue we’ve seen is with your “Recents” list showing up.
Same behaviour, I hit continue, the icon pops up and then the app dies. After the clean up and reinstall, the error doesn’t show anymore. I can share the logs if you want.
BTW, the OSX version I’m on is 10.13 Beta (17A315i)
