Retina MacBook Pro - why so slow to boot?

[gwelmarten]

Hi
I just got my Retina MacBook Pro. 2.6Ghz CPU with 16GB Ram.
I've got it all configured (gone through setup, no programs or documents yet) and am surprised to find how slow it is to boot.
My 13Inch 2010 MacBook Air with Mountain Lion boots in 13 seconds.
My Mum's 11Inch 2010 MacBook Air with Snow Leopard boots in 9 seconds.
My Retina MacBook Pro boots in 21 seconds.

As the Retina MacBook Pro has a faster CPU, more RAM and a faster SSD, why is it that it takes so much longer to boot?

there is something wrong then. Should take no longer than 9 seconds from the startup chime.

Should I return this to Apple then as Faulty? I'll try a restore first.

def restore first. That is what they will do before they will exchange it. Best to do it yourself before having to hand over your computer for 2 days.

Do you have an external drive attached or USB Hub?

Disconnect it and reboot and see if its faster.

Try a PRAM reset or SMC reset.

The startup time is subjective to the apps you have, and the ones you have turning on at startup.

Try a PRAM reset or SMC reset.

I second this suggestion.

My Mac Pro takes about 3 minutes to boot!

21 seconds is pretty fast already.

It sounds like you have too many apps launching on startup. try this...

Preferences > Users & Groups > Login items > highlight and delete all those that you DON'T want automatically launched every time you start up your Mac.

Will make a significant difference in launch speed.

Open up System Preferences and make sure your boot disk is highlighted and selected. This can shave more than 10 secs off boot. It is Apples very simple way of "blessing" the boot drive so the system bus can find it without looking everywhere for some kind of boot device.

I'm amazed that 21 sec is considered "slow."

I never said that - I was concerned that something with 2x the specs in every component represented a boot time of 2x as long.

Yeah, I'd say that there's something not altogether right. I just timed by rMBP with my trust iPhone stopwatch. From startup chime to login screen was 10.8 seconds.

 

[halledise]

mine's currently taking 53 seconds from chime to login page

This is an old thread, but I have an RMBP that's been slow to boot up lately. It takes about 30-40 seconds for the Apple logo to appear and the OS to start it's boot sequence. That period before the Apple logo appears is typically EFI-time, and I couldn't figure out for the life of me why the firmware was taking so bloody long to boot and prep.

I found this thread through google, and, well, it turns out that you're exactly right! I had messed around with refit/refind a while back and it looks like I forgot to re-bless my hard drive. My boot times seem to be back to about 9 seconds.

Thank you!

Wow. I was so skeptical of this being true, but sure enough I followed the steps, did a restart and it changed my boot time from 44 seconds to 11.6.

Great tip!

This was the perfect, easy solution to my VERY SLOW boot up! There was an iTunes help file that wasn't found so it was hanging up every time. After I deleted it, I deleted another program I didn't want to launch on start up.
My machine is back to blazing fast launch......Thanks a bunch.....
