Build starts immediately, debug takes forever... Why?

I’ve noted that when running our application in debug mode, it will take at least a minute or more before the progress bar starts to show any progress. This time seems to get longer the more you make changes and run in debug mode. However, if you actually build the executable, the progress bar starts right a way actually finishes in less time than the debug build. Anyone know why this is?

This is that save thing. Save before you run and it goes away.
There’s a hidden Mac setting to disable this feature somewhere floating around the forum.

You can try disabling project auto-saving to see if it reduces the delay:

Thanks, every little bit helps.
