That's a Mac OSX thing. It's verifying the apps.

If it's Intel-compiled apps, it's also that Rosetta is translating them to run on M1 when they're first run, as I understand it.

Both of these are first-time launch issues, so comparing launch times on the second launch is probably more reasonable.

Good point. I'm really surprised they don't translate during installation (ahead of time).

I believe they do.

In certain cases, such as when they come from the App Store. I believe other apps do not get this.

I think Installer.app triggers the AOT translation, too?
