2. Resetting the System Management Controller

Every MacBook Pro has an inbuilt hardware function called System Management Controller. While we won’t get too technical to explain its various functions, we will tell you that a reset of this controller can sometimes tremendously help in improving the speed of your Mac.

Don’t worry, resetting this controller will not harm your Mac in any way. It won’t even change any of your content. It just resets the hardware and in most probability,will solve your slow MacBook Pro problems.

Follow the steps below to carry out a System Management Controller Reset on your MacBook Pro, to speed it up instantly

How to reset your MacBook Pro’s System Management Controller?

  • Turn off your MacBook Pro
  • Plug in your MacBook Pro’s power cord into the wall socket
  • Now, hold down the Left Shift + Option + Control + Power Button, simultaneously, for 10 seconds
  • When you do the above, your Mac won’t power on but a reset will be registered
  • Release all keys after 10 seconds and turn on your MacBook Pro like you normally do
  • Your MacBook Pro slow performance problems are hopefully solved!

Please note that when you press the above mentioned combination of keys, your MacBook Pro should not turn on. If it does, you probably didn’t press one of the keys properly. Do it again until you are able to press down all mentioned keys for 10 seconds, without powering up your MacBook Pro.

3.Macbook Pro PRAM reset to fix mac running slow problems PRAM Reset (Updated on 23, March 2014)

Just like the SMC reset discussed just above, another reset called the PRAM reset has also quite a few Mac owners fix their slow MacBook Pro problems.

Again, like the SMC reset, the PRAM reset will not delete your user generated data. The only thing you might have to restore after carrying out this reset is probably some system preferences like time, date etc., something that will take you just two minutes at the most.

How to carry out a PRAM reset to fix MacBook Pro slow problems?

  • Shut down your MacBook Pro
  • Press the power button
  • Press Command + Option + P + R in combination, all at the same time, before you see the grey startup screen
  • Press and hold until your MacBook Pro restarts
  • Release the keys when you hear the familiar startup chime sound that your MacBook Pro makes when it starts up
  • Your PRAM reset should be complete

4. Check for Power Hungry Apps

Sometimes, MacBook Pro slow performance problems can be caused by just one or two apps, apps that are very resource hungry, apps that hog all your processing and memory resources.

MacBook Pro X Activity Monitor Speed Check

Check Your MacBook Pro’s Activity Monitor to identify power hungry apps, to potentially uninstall or substitute them.

To check if your MacBook Pro is being affected by such apps, please carry out the following check.

  • Go to the Applications Folder
  • Select Utilities
  • Select Activity Monitor
  • Select CPU tab, shown at the bottom
  • Check the % Idle statistic
  • If your % Idle statistic is always less than 60% or 50%, some of the apps you are using are using up way too much memory than what is normal
  • Check the list of active apps to see which apps are the culprits, the culprits that are slowing down your MacBook Pro
  • Uninstall thise apps. If you need the apps, look for an alternative apps that are more compatible to run on your MacBook Pro. You can also try re-installing that app to see if it will consume less resources after a re-install

5. De-Clutter Your Desktop

If you are like many of the amateur MacBook Pro users out there, chances are that there are about a 100 icons on your desktop. What you must understand is that these icons are not static. In other words, your MacBook Pro’s processor is constantly checking up on these icons, making sure that the links are always live and ready to go.

MacBook Pro X slow speeds caused by desktop

If your MacBook Pro is slow and your desktop looks this, just cleaning up your desktop icons can help your MacBook Pro run faster!

That process takes up a lot of memory and CPU resources. Try to limit your desktop icons to just 10 or 15 icons. As for all the remaining ones, you can put them all in a folder called, let’s say, ¬†“Second Desktop” (Folder name is just an example, you can use what you like). That way, you will de-clutter your desktop and also not be too far away from all the shortcuts that are important to you.

Other ways in which you can potentially fix your MacBook pro running slow problems is to buy and install more RAM, install a SSD (Solid State Drive) hard disk and also use just a few apps at one particular time, reducing your multi-tasking work. All these fixes can help speed up your MacBook pro to various extents.

    I had no idea that there was something called a system management controller in my MacBook Pro! And yes, resetting it made a huge difference!

    Resetting the SMC on Mac portables with a battery you can remove

    I’m not sure if you’re right. That’s the official instruction:
    Note: Learn about removing the battery on MacBook and MacBook Pro.
    Shut down the computer.
    Disconnect the MagSafe power adapter from the computer, if it’s connected.
    Remove the battery.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Reconnect the battery and MagSafe power adapter.
    Press the power button to turn on the computer.

    Wow, the cleanup software really helped. Turns out my MacBook’s hard drive had just 248 MG of hard disk space left. The software freed up 17 GB of junk. Incredible. Made all the difference to both booting and browsing speeds. I use my MacBook to just browse!

    No wonder this post got shared on Prismatic :) Kudos – Keep it coming!

    Early indications are that reseting the SMC has made a noticable difference.

    smc reset is an awesome way to boot performance on your MacBook Pro. I usually end up using it at least once a month and it always seems to do the trick….have to try clean my mac yet..

    I did all you said but using the power button because mine broke.its still so slow (using my iphone). it just drastically reduced itself out of nowhere yesterday. I bought my computer new and didn’t come w a disc. updated to mavericks.all my data is backed up. but I use my computer 10 hours a day and sending it off to be fixed would affect me greatly.anything else I can do? can I reset it wo a disc? thanks

    • Michelle Smith Reply

      Hi Dave. It sounds like your Mac badly needs a SMC reset for which the power button will have to work. Is there someone savvy enough to get the power button working. If that could happen, you could try the SMC reset and I have a feeling it will help.

      Also, how much hard disk space do you have? If it isn’t a lot, you must try clearing it up as added free disk space can make a big difference to performance levels.

    Thank you for the information. I reset the system management controller. It seems to be helping but I haven’t had enough time to know for sure. I did declutter my desktop. I already knew that was a bad thing to do and it wasn’t that bad, but it’s much better. I still think my MBP is running too slowly though, but better than it was. Frustrating!

    • Michelle Smith Reply

      Hi Lizzy

      Did you try the PRAM reset as well? Also, how much free disk space do you have on your MacBook pro? A full hard disk can also really slow down your MacBook’s performance, even if it is a SSD!

    Thanks for this useful article. SMC reset worked like a magic to speed-up my MacBook Pro.

    Hi, I tried to do everything but it’s still running slow. Also, my idle statistic are always 80-90%. I’m getting frustrated because I really don’t know what to do anymore. My laptop is only 1 year and a couple months old.

    • Michelle Smith Reply

      Hi Stephanie. Sorry to hear that. Can you tell us what specifically your MacBook Pro is doing wrong? Booting up slowly, not being able to multitask or maybe just hanging up all the time?

      If you are more specific, we can maybe try to help you with some fixes. Can you also go to our site’s search bar and type in Apple Diagnostics and then go to the post that mentions it. There, you will find instructions on how to do a hardware test. I suspect that some hardware component might have failed in your MBP

      • Stephanie Francisco Reply

        It just keeps on hanging up. Like even if I type something, I need to wait for a minute before it appears.

        • Michelle Smith Reply

          Wow, that is really bad. I would try the SMC and PRAM resets again. Are you sure they worked the first time around? If the resets don’t fix it, I think you might need to take it to a service station. It could be that your hard drive is corrupted or damaged as well.
