View Full Version : Help!!! Really slow boot times after clean install (factory Restore).

Hi guys, hope you can help me here.

I followed apple's own instructions for a clean install. I booted from the USB restore disk. First I ran Disk utility to erase the current volume. Then I just did a normal install.

When I do this the macbook air takes around 1 minute to boot, with the loading circle animation rotating 16 times. Prior to restore it was 1.5 times.

Now I have tried restoring the same way a few times since and it does the same thing. I have also left the system idle and restarted it multiple times to see if it will "bed in" but it stays just as bad!

Does anyone on here know why this might be?

Thanks in advance.

Have you selected your drive as start up volume from System Preferences > Startup disk? You can also try SMC and PRAM resets.

Thanks for the tip. Can you tell me more about smc and pram? What do I need to do?

Cheers

Thanks. Any negatives associated with resetting PRAM and SMC?

your clock might get reset until your wifi connects again (won't affect the wifi itself), and your brightness/audio settings might change from when you turned it off. benefits outweigh the costs by a huge amount if your computer is being slow and this fixes it.

Neither fixed it. Really cheesed off :(

I suggest you just live with it for a couple of days. When I installed an SSD into my MBP, the boot time actually increased for a couple weeks. My apps still launched lightning fast, but the boot time just baffled me. After a while though, all of a sudden, my boot time cut by about 3 x. I'm guessing the system just does some maintenance work and eventually gets used to it. If you're still getting 1 min boot times after a month, take it to Apple as it might be a hardware issue. In the meantime, I'm sure waking from sleep is still fairly fast right? Why are you always shutting down the computer anyway?

When you used Disk Utility to erase the drive, did you activate the "security erase - zero all date" option? That might have caused a slow down of the drive until the controller could do its clean-up routine.

suggest you go again, this time:

* run hardware test first - hold down 'd' key as you start up from usb stick.

* then restart holding down the 'c' key and select a more secure erase option in disk utility.

something's definitely not as it should be. :(

when you get around to the actual Mac OSX install, deselect everything you don't need in the 'customise' section

let us know how you get on

Go into system preferences.

Click on Start Up

Choose OSX and press the lock icon bottom left

Reboot.

Fixed it. You're not going to believe me but I opened photo booth then restarted. went from 1 minute to 10 seconds and seems to be staying that way!

Riddle me that!!!!

We just came home with an 11" for my son. My wife has the identical one. Her's boots in 15 seconds. My sons boots in 40 seconds. No matter what we try we can't get it to boot faster. His old macbook is as fast with 5400 spin drive. Anyone have any ideas before we return it?

Do a fresh install with a Secure erase. Regular Formats are bad for SSDs and can degrade performance.

I tried it and it seemed to work until I used Super Duper to copy over my stuff. Then back to where I was. Slow boot.

Hmm. You should try a utility that wipes free space' but i do not know of any for mac :/

If it slows down after you move your old data back on, more than likely some system file got messed up somewhere down the line. The easiest thing to do is simply wipe the drive, do a clean OS install, then manually reinstall the software from before and move the data back. Super duper or any cloning utility will easily just copy the bad system files back over, defeating the purpose of your wipe.

The OS X standard "Disk Utility" can erase (zero out) free space.

This would be annoying for sure, but how often do you boot this thing? I only boot MAYBE once every 2-3 weeks.

Stupid idea on an SSD. Zero-ing out a drive writes data to every block. To secure erase an SSD, you want to empty every block. Completely opposite effect.

SO............ How do you empty out the blocks on an SSD?

Yes, I completely agree. However, the poster asked for a way to wipe the free space on his drive, and that is one way to do it. I think it has been suggested on the forums that eventually the ssd controller will empty that zeroed-out free space resulting in the desired effect. Too bad we don't have a "trim" command to do it instantly.

You might as well just boot into linux using a USB and do a secure erase command. Shouldn't take much longer than a zero-ing out.

Does that "empty" the cells?

Using System Preferences and choosing the startup disk worked for me :)

I tired exactly that and no improvement

I guess my feeling is for $1300 with tax it should at least do what my wife's Air does. Close at least?

I made a bootable USB Thumb Drive with a runnable Ubuntu 10.10 Linux on it. Does the "secure erase" reset the SSD on that version of linux?

thanks,

OK - so this really has no effect on the day to day usage of the unit - it's just for curiosity sake as much as anything? No problem with that, it just seems like a lot of trouble to return something to Apple because it "academically" doesn't do what you expect it to. But to each his / her own.

Well I was thinking that as well. I went over to the Apple Forums and someone posted just leave the computer on steady for about an hour and not allowing it to sleep and then try the boot up again. I did exactly that and it fixed the problem.

Now my son doesn't want the 11". He is getting a MacBook Pro. I have a 13" ultimate but darn if I don't love the 11" form factor. Would love to keep the 11" but........:)
