i have a macbook pro 2011 with 4GB RAM, 320 GB hard disk, mountain liion installed. for the past 2 weeks, it is taking nearly 10 mts to boot.

It is taking nearly 10 mts for moutain lion to boot. I have used Mactune up utility to check disk status and there are no problems with the disk. Double checked with SMART utility and it reported no issues with the disk. Out of 320GB disk, 220 gb is free space in the disk

Ran anti virus to check for any virus relalted issues and found none. I have also checked programs which are part of login in User and Groups. I found only iTunes helper and unchecked the same. Post this operation, i had shutdown my pc and then re-started and am still experiencing 10 mts window for start up. I am not seeing errors in the macbook pro. can someone advise what needs to be done. do i need to reinstall mountain lion. if yes, can someone advise me how to reinstall mountain lion without erasing disk.

MacBook Pro, OS X Mountain Lion (10.8.2)

Yes that is correct. At the end of 10th minute, Mac booted and post that, Mac works like a breeze. This 10 minute duration for booting seems consistent.

Thanks Barney for your response. i am contemplating rebuild of OS as a last resort. i am new to mac so that it would really help if you could provide step by step instructions to reinstall OS without deleting data.

Although I too am inclined to recommend reinstall from Recovery, there are a couple of things to do yet.

Run Disk Utility after booting into Recovery mode and verify/repair your filesystem permissions.
Boot into Safe Mode
1. Reboot while pressing and holding the Shift key until the grey progress bar appears.
2. At the login box with grey textured background, enter your name and password. Stop!
3. Press and hold the Shift key, then press the right-arrow next to the password field.
4. Release the Shift key when you see your desktop appear.
Reboot normally -- is this boot any quicker?

The Safe Boot Mode cleans out some caches and rebuilds others (such as the font cache). The other concern that I have is that Macware's Mac Tune Up only shows capability through OS X 10.6.

Aw, vijay -- I wish we could have nailed it for you, but in the end, it's the result that counts, eh?

All the best.

Did you do all of Viking's recommendations? Can you tell us which one helped you?

🙂

Hello Bee,

i had followed all of the instructions provided by viking and then reinstalled the os.

I should particularly thank you for the support as you have very diligent and methodical in the identifcation of the problem.

One clarification - i dont need to install any antivirus or any of the tune up tools - is this correct.

Also in the future, if there are any issues, is this forum to raise the discussion for resolution.

thanks for all your support.
