Q: My mac book pro thats only a year old is being really slow.

First thing is to figure out if the drive is too full. Click once the hard drive, and type command + i (both together). From the Info that comes up please record Capacity: .... and Available:....  and post back.

This is just a first step.

And please tell us also what version of Mac OS X you are running. (Click on Apple menu and select About This Mac.)

Why is my computer slow?

Security Issues Warning List

..Step by Step to fix your Mac

Click once on the hard drive icon - top right of your screen.

Then type command + i and hit return.

You will see something like this. Tell us what the last two lines (in what is shown below) say.

Capacity?

Available?

Ok, that's great. Your drive is not close to full. Do you have a back up?

Before doing the next steps, it is important to make a back up, just in case something goes wrong. A back up is ajust a complete copy of everything that is on your computer, and you need an external hard drive for this.

A couple of other questions.

You posted that the computer is slow - what are the main things you do on the computer, and what is it that is slow?

Do you use Safari for internet browsing?

I have only had my mac book for about a year and its now starting to run slow i dont know what to do.

Before you proceed further, what and where is your slowdowns occuring and what do you see on the screen when it occurs?

If it's on the Internet only did you try other machines or other browsers, or other user accounts on the same machine to isolate where it's occuring?

If it's occuring on files loading when your offline, it's likely a bad hard drive or corruption.

Did you install something like Mackeeper or anti-virus software?

Did you try rebooting the machine? A runaway process can make the machine slow.

Is it only appearing with 3D games?  A 13" MBP is not a 3D gaming machine, neither are most Mac's.

3D gaming on Mac's, what you need to know

Is it only appearing in one program and not others?

You should have a backup system in place regardless

Most commonly used backup methods

Regarding your fans, see KB Article:  http://support.apple.com/kb/HT1411 Apple Portables: Resetting the System Management Controller (SMC)

Well that's a start.

We have reboot covered, fans are going, it's only on Internet and Firefox has blue circle loading issues, since that  occurs on the tabs so it's looking like a strickly Firefox issue.

Have you rebooted and not start Firefox, then tried Safari, does the issue still occur?

Check under Apple Menu > Software Update for any updates to OS X and or Apple programs and apply.

If it goes away using Safari, try uninstalling all Firefox add-ons and Firefox, then use Safari and check here for updates for your browser plug-ins.

Next install Firefox again from the same link above, it's version 20 now. But don't install any add-ons.

If your problem goes away then I think you found the problem.

Also check your Applications/Utilites/Activity Monitor and click on CPU to see if any process is consuiming more processor cycles than it really should be (like 100-200%) that indicates a runaway process and mention it here.

Is your computer less that 12 months old? If it is, the warranty is still in effect, and you can ask a person at an Apple store to work with you to solve these issues.
