Mountain Lion Slower Boot Times?

[klh6686]

Mountain lion loads a good bit quicker for me. I'm on an old sata 2 ssd and on lion I could watch the loading wheel at the apple logo about 5-6 rotations.

Mountain lion I don't even see the loading wheel, it's on the apple logo for a couple seconds at most.

@frrilay, thanks for your answers! Replacing those two kexts made my boot time back to what it was in Lion. Thanks!

You can find this files in: /System/Library/Extensions

Just copy AppleAHCIPort and IOAHCIFamily from Lion /System/Library/Extensions to Mountain Lion /System/Library/Extensions

If you replace your IOAHCIFamily and AppleAHCIPort kexts with ones from Lion it'll boot faster (at least that's the workaround I found, it also fixed a problem I had with my optical drive not being correctly recognized, especially in the built-in DVD player).

Thanks for this tip! It worked on both my SSD and my normal hard drive. Terrific.

You can actually get pretty decent boot times in ML, as shown here:

Speed Demon - YouTube

Quite impressive considering the fact that some of the hardware involved is more than 2 years old.

Very impressive, its your hack?
Intel 520 ssd its a game changer
And i guess it have minimal possible kext loading

My i7 950 with samsung 128 ssd make a nice 24.6 sec with lot of peripherics/kexts loading.

I can confirm it too.
