What do I need to do if my macbook pro is extremely slow?

Start from your recovery system. OS X Lion or OS X Mountain Lion includes a built in set of utilities in the Recovery System. Restart your Mac and hold down the Command key and the R key (Command-R), and keep holding them until the Apple icon appears, indicating that your Mac is starting up. After the Recovery System is finished starting up, you should see a desktop with a OS X menu bar and a "Mac OS X Utilities" application window. Note: If you see a login window or your own desktop and icons, it is possible that you didn't hold Command-R early enough. Restart and try again.

When your computer finishes starting up, choose Disk Utility from the Utilities window.

Click the First Aid tab. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.

Select your OS X volume.

Click Repair. Disk Utility checks and repairs the disk.

Let us know what Disk Repair reports and whether it was able to repair it or not.

After that, then Repair Permissions.

No need to report any Permissions errors........we all get them.

See ds store's excellent user tip - Why is my computer slow?

May give you some insight as to what's going on under the hood...

Sorry for the delay. The SUID file thing is something that shows up in

Permissions Repairs you can safely ignore. No need to worry.

Have you tried anything in ds stores tip 2 posts above?

Can you tell us how much RAM (Memory) you have? It's listed by clicking on the  in your title bar....go to About This Mac and it's in the 1st window.

We would also like to know what size hard drive you have and how much free space is on it.

If you click on your Hard drive icon (should be upper right hand corner of your screen), or the Finder in your Dock...when the window opens it says at the bottom how much Free Space you have on your drive.

If you go to the , click on About This Mac, click on More Info... in that window. The next window says how big your hard drive is under Hardware....click on Serial-ATA.....look under Capacity:

We need to know this cause if a hard drive is too full it slows things down and creates operational difficulties.

Forget that, seriously.. It's a hard drive failure waiting to happen. Take it to the genius bar after appointing with them asap, they will run diagnostics that will give you an in depth reasoning for your problem. Good luck! x

Is it just slow on the internet? Is it slow with other applications while not online?

Did you buy it new in July or was it a used one?

I think I'm with iamjaycee on this. You have a one year warranty. Might as well have Apple look at it.....no charge. Shouldn't have to put up with that. Before sending it or taking it in make sure you have a backup in case they have to put in a new hard drive.

I would also consider purchasing Apple Care which will extend the warranty another two years. Good idea on a laptop.
