You obviously have an SSD, right?

My late 2006 core 2 duo macbook can reach the Snow Leopard desktop in under 10 seconds and it is only SATA at 1.5Gbps.

I've been running Mac OS X since 10.0.  I even used it on a Power Macintosh 8500, that OS X directly from Apple didn't support, but that would work if you installed some drivers that some developer cooked up for the older hardware.

OS X ran OK on my 8500, but was so slow as to be unusable.  It was a crushing disappointment, as at the time I didn't have the cash for a new box. 

Older releases of Mac OS X showed a progress bar during boot, with messages that reported what step was taking place.

My 10.8.3 Retina Display MacBook Pro shows the circular progress indicator for five or ten seconds - I think mostly to run a memory test - then the screen changes color, and I'm presented with my password prompt just a second or two later.

I'm having a hard time figuring out how OS X can boot so fast.  It's not just the kernel initialization, there are a lot of demons to start, the display server and so on.

We have the Kernel Extension cache, but there must be a lot more to it.  This speed can't be explained just by the faster CPU.

Try booting your Mac off of Windows or Linux.  There is no comparison.

Curiously,

Mike
