Long time White Screen on imac (before apple logo apears)

[tra]

Hi People,

I have 2 macs

one iMac 22" model mid 2010 3,06Ghz OS X 10.6.4

one Macbook Pro 15" early 2010 2,4Ghz OS X 10.6.4

On the mac book pro, the White screen(firmware?) appears for about 5 seconds, and then it shows the Apple logo with the spinning wheel, and then boots to OS X

The imac shows the White screen(firmware?) for about 15 seconds, and then show the Apple logo with the spinning wheel, and then boots to OS X

Why does it show so long on my iMac?

And there a solution?

That's weird, I have an old PowerMac and it boot in 10 seconds to OS X

I had that issue before with my MacBook and I managed to fix it by going into System Preferences > Startup Disk and making sure you have the right one set. Even if you do, try to set it again, reboot and see if the problem goes away. Again, I don't own a PowerPC-based mac so I can't really give much advice, but try that.

Do you have an external harddrive plugged in at all?

I get this when I reboot due to my Firewire external harddrive, it can last upto a minute for me

Do you have an iPod shuffle plugged in?

As the person above stated:

 

After experiencing a longer than usual delay at boot with my macbook pro os x 10.9.2, right before the apple logo shows, I followed the suggested procedure above.

 

Go into System Preferences > Start-up Disk > Select your main drive from the list and click on the "restart" button shown therein.

 

Thanks!!!
