That video plays until you go past the welcome screen. You can turn on a new machine, watch the video, power down and restart and you get the same video again.Then they reinstall the OS on the hard drive? That video only plays once.
Well he did say "I bet" and not "I know".This is the key to this whole thread. So really you don't know do you, just assumptions?
Nice.Who said they turn them on?
IIRC they actually do turn them on prior to shipment to make sure the parts (especially RAM) are installed properly. I was told that the Mac is force shut down as soon as the startup video appears.Nice.
Parts are "power tested" as the last stage of the manufacturing each part (PSU,...). This isn't done by Apple, as they don't actually manufacture the parts. Apple could (and should) do a power up of the combined hardware, then slap in an imaged drive. And the power testing lasts a couple of seconds. It's as bare minimum as you can get. It's nowhere near the 72 hr burn-in that used to accompany systems after assembly.
That was eliminated years ago to save money (less people, less warehousing space prior to packaging).
This is the most I'd expect. A bit past checking if it POST's. It's still rather minimal though. Lots of room for defects to sneak through. Other vendors are just as guilty though, including the component makers (nothings thoroughly tested from top to bottom). That was usually left to random samples, but has dried up in the last decade for the most part.IIRC they actually do turn them on prior to shipment to make sure the parts (especially RAM) are installed properly.
