Speaking of progress bars. I still don't understand why they brought the boot up progress bar back. It's not even real. When OS X came out, there was a real progress bar. It would show every system as it was loading like Classic Mac OS did. At one point they removed the text that it displayed and made the progress window fake. In that it based its loading bar speed on the previous boot. Which meant it would sometimes not even finish or others would finish early before booting was finished. But as the Intel switch came along and computers got faster, they removed it completely to simplify things.
But now it's back. For no reason. It's never accurate. Why is it there? Just show a spinning progress indicator to show the computer isn't frozen and be done with it. Boot up is relatively fast anyway. Especially on flash based machines.
Might as well bring back the Happy Mac icon.
I demand the march of Inits back.
Abed, you can probably set an NV args parameter to only boot in robot-barf mode so you can see everything as it loads.
I don't see anything on my Mac Pro because I have an unflashed PC GPU.
Was very surprised by the white on black boot bar on a 15" retina I put Yosemite on today. What a gorgeous machine. No desire for a laptop that big, but damn.
I don't mind the progress bar because I have a fusion and it's fast. I can lord it over traditional HD boots

But anyway, I've seen white apple on black loading screen.. What is the significance of this vs black on white?
