BTW, for anyone who wants a clean start for testing, hold down Control-Option-Command and choose About SetShot from the SetShot menu. A dialog will confirm that you want to reset to factory defaults, which means deleting all your snapshots, journal, settings, and so on. It’s extreme, but useful for testing.
Technically not first launch, but I did get such a request after re-launching after using the clean start key combination. This is on v1.0b19.
Drat! I must not have tested that as thoroughly as I thought, and tracking down the particular calls that trigger that dialog is proving really hard.
No worries. I actually appreciated the prompt. If I can reproduce it I’ll let you know.
