How to Speed Up a Slow Mac

If you have noticed that your Mac isn’t running as quickly as it once did, don’t panic! It is completely normal for your computer to begin to slow down within a few years of purchase, mostly due to normal day to day build up. There are many things that can cause system lag and likewise, many ways to remedy the situation. Although there are software applications you can buy to help you speed up your Mac, I suggest trying some free options before jumping to software support and spending money. So, I have compiled a list of 10 things you can do to speed up your Mac. I suggest trying all of these for the best results, and since these are all free options, you have nothing to loose!

1. Keep your computer clean. It may not seem like an important step in speeding up your computer, but a tidy computer is a faster computer! This is especially crucial if you are using a mac laptop because dirt and dust can make their way into your computer through your keyboard and build up over time, dampening critical air circulation. Make it a regular habit to clean your computer from time to time with dedicated screen and case cleaners. Also, using products like condensed air to force out excess dust from under your keyboard may help to release any particles that may be building up under there. Also, make it a rule not to eat by your computer. I know so many of us are used to eating and working, but its just not good for your machine to be so close to crumbs, especially food crumbs! So, make sure to keep your laptop clean, and try to prevent crumbs from sneaking in through your keys to keep your machine running at top speed!

2. Keep your computer elevated. Again, if you are using a laptop this is another critical factor in the performance of your machine. Airflow is such a determining factor in the performance of your laptop and can be a major reason your laptop isn’t as snappy as it once was. Now, this doesn’t mean you necessarily need to run out and buy one of those stands for your laptop and an external keyboard, but it means you should always use your laptop on a clean hard surface, minimizing the time it spends sitting on fabric like sofa’s, beds or carpeting. Fabric can be a problem because it usually contains a good amount of dust particles and the fan on your laptop will end up sucking that in like a vacuum and inhibiting the flow of air in your laptop. You can help to increase air flow to your laptop, not only by sitting it on a hard surface, but also by propping up the back of the machine with objects like erasers or books. The goal is to give air the space to move around your computer which will keep your device cool and free of dirt and dust.

3. Keep a clean desktop. You may not know it, but the number of icons you have sitting on your computers desktop actually contributes to the speed of your computer. I try to only have my “Macintosh HD” startup disk on my desktop so that I have as few items as possible for my machine to render upon startup. So, go through any items you have on your desktop, file them away properly and see the speed of your machine increase.

4. Clean up your hard drive. Make sure to keep an eye on your hard drive space by right clicking your “Macintosh HD” icon and selecting “Get Info.” From this menu you can see how much space you have available on your machine. If you are running low on space (less than a quarter of your original drive space remaining) I suggest you go through your computer and remove excess files. You can move anything you don’t need to the trash (make sure to empty the trash when your done!) or you can move files off your computer and onto an external hard drive. If you are not sure what is taking up space on your mac you can always download the free application Disk Inventory X. This simple to use software can help you identify what applications and files are taking up the most space on your computer and you may be surprised that your precious hard drive space is being eaten up in the most unusual ways! If applications are your culprit, you will need download the free application, AppCleaner that helps you safely remove unused or unneeded applications and there associated files.

5. Reset Safari. If you are having an issue with the speed of Safari especially, you may need to Reset Safari to clean out its cache. From the Safari Menu, select “Reset Safari” and a box should appear with checked boxes asking which items to reset. I suggest resetting everything, but check the list and make sure there isn’t anything you don’t want reset because the reset will basically wipe all stored information (but not your bookmarks). Things like your downloads file, the autofill forms for websites, and stored passwords for sites will all be wiped. You may be a little nervous to do this, so before you take this action, I suggest visiting any important websites to figure out what your usernames and passwords are for each (because after the reset they won’t autofill again until after you have revisited and reentered your information). If you have a computer that is a few years old, you would be surprised to see how many websites Safari has been storing information for, even ones you haven’t visited in years! This action can take a few minutes, depending on the amount of information you have stored, so don’t worry if you see the beach ball pop up, or if Safari has a little lag once it reboots! That will go away momentarily.

6. Make sure your software is up to date. Apple is frequently sending our Mac’s software updates for everything from iTunes, to Safari to Mail! If you don’t have your Mac set to automatically check for updates, you may need to go in and manually check every once in a while to make sure your computer is running on the most up to date software! From your Apple menu, select “Check for Software Updates” and let your computer scan for any new updates. You will need to be connected to the internet to do this, so make sure you are connected via Wifi or cable.

7. Close out of applications. This may seem like a simple solution, but you would be surprised at the amount of people who do not realize that they have not properly closed out of applications. With a Mac, you can “X” out of an application, but the application may still be running in the background. To check this, take a look at your dock and see if any applications have a little glowing light under neath them. If they do, that means they are still running. To close any applications you don’t need running at the time, right click the icon and select “Quit”. If the application doesn’t quit within a minute or so, you may need to try again and select “Force Quit” as sometimes applications time out while they are running and stop responding to normal commands. Don’t worry if you have to use “Force Quit,” it will not damage your computer or the application.

8. Unplug any peripheral devices you aren’t using. This is a common problem with desktop Mac’s that are stationary. Often times, because we don’t move our computer around, it tends to have lot of extras plugged into it, even when those extras are not in use. Things like printers, external hard drives, card readers and usb thumb drives can all slow down your Mac’s performance. So, unless you are using the peripheral device, unplug it so it doesn’t weigh down the performance of your computer.

9. Restart your Mac. Sometimes temporary lags in performance can be stopped with a simple restart. It is recommended that you first close out of all your applications before attempting the restart. Once you have quit out of everything, you can proceed to “Restart” from the “Apple” menu. If you get an option in the dialog box to “Open Windows upon restart” make sure that box is unchecked so that you get a clean reboot.

10. Shut down your computer. Although Macs do not need to be Restarted or Shut down in between uses, if it has been a while since you last shut down your computer, you may want to give your Mac a rest with a Shut Down. From the “Apple” menu, select the “Shut Down” option and once your computer has shut down completely, give it some time to rest before starting it back up. I recommend running the shut down sequence in the evening before you go to bed, and then giving your computer a quick cleaning while its off. Make sure to leave it on a hard, dry surface, and keep it unplugged if it is a laptop.

If you have trouble or are unable to complete any of these tips, I suggest reaching out to Apple directly for assistance. If you do complete these tips and still see a good deal of system slowdowns and lag, reach out to Apple via the AppleCare hotline or your local Apple retailer to get further information on diagnostics that can check to see if you are having a major system issue that is causing the lag. Lag can sometimes be a warning sign of disk failure, so always keep your files backed up just to be on the safe side!
