While Macs are quite reliable as far as computers go, having a second-hand model might prove more problematic than you expect.

I’ve noticed that MacBooks get slower after a certain period, which I think is because there’s so much data in the MacBook slowing it down. there are a few things you can do to Improve Your Second Hand MacBook Performance. However, if you follow this guide below, your MacBook will run much faster than before and feel like a brand new Mac again! So give it a try and tell me how you get on!

Scan for Potential Viruses and Malware

Let’s start with cybersecurity threats. Like already mentioned, MacBooks are known for their reliability, and security should not be an issue for the most part.

However, there are instances when you might have a malware problem without realizing it. Opening a random URL by clicking an aggressive ad while surfing the net or clicking on a file somebody sent you might result in attracting unwanted viruses on your laptop.

Of course, if you have reliable antivirus software, it should detect and eliminate such threats before they manifest and cause the MacBook any harm.

Scan the system with a reliable anti-malware tool to locate potential malware or viruses. If the scan reveals corrupted files, you will have to remove them from the system.

Keep Tabs on Drive’s Storage

Do not end up in a situation where there are only a few free gigabytes of storage on the computer’s drive. If you do, the laptop will struggle to perform optimally.

Your Mac’s drive likely has not that much storage in the first place, so every little bit matters. To free up the storage, you could:

  • Use a cleanup utility tool to get rid of app caches, extensions, system backups, and other temporary junk data
  • Stick to streaming platforms instead of keeping large media files on the computer’s drive
  • Transfer files to an external hard drive or iCloud
  • Get rid of localization files, old downloads, duplicates, useless applications, and other unnecessary data

Clean Dust Inside

If you are reluctant to clean the dust inside the MacBook yourself, ask someone who has experience with this task. It is understandable that you do not wish to take the laptop apart since you might damage the hardware.

There should be a computer service shop nearby. Get in touch with them and ask whether they can clean the dust inside the MacBook.

Once the filth is removed, you will notice that the MacBook is performing better and not making as much sound. Overheating should also be more manageable.

Speaking of which, if you notice that your Mac is overheating all the time despite removing the dust inside it, invest in a cooling pad. A relatively cheap accessory that provides a laptop with a source of cool air is quite valuable.

Invest in New Hardware

New hardware might seem like too much of a commitment, but if your second-hand MacBook is not working properly, a boost from extra RAM or a new solid-state drive might be just the thing to solve your problems.

However, keep in mind that replacing or adding hardware is not an option for every Mac model. Some Apple computers are manufactured in a way that they can run only with original hardware. 

Nevertheless, if you have the money and hardware compatibility is not an issue, you should not hesitate to upgrade MacBook’s hardware.

Make Sure the OS Is Updated

Missing system updates might be one of the primary reasons behind poor Mac performance. Nevertheless, apple continues to push new macOS versions to improve the overall experience of those using MacBooks.

It is worth pointing out that keeping macOS updated will do more than just boost the MacBook’s speed. You will also benefit from the latest cybersecurity upgrades as well as new features. Therefore, whenever a new macOS becomes available, make sure to update your MacBook.

Optimize Your Browser

You might have the most problems with an internet browser. It might not be that common, but some Safari users face the issue of the browser consuming too many computer resources, particularly memory.

One of the best ways to solve this problem is to remove redundant browser extensions. If that does not help, you could also switch to a different browser. For example, even though Safari is the default macOS version, MacBook owners use Opera, Firefox, or Chrome.

Declutter Desktop

Cluttering your Mac’s desktop with random documents or app shortcuts might make it more convenient to access the files, but each desktop icon is a hindrance to the overall MacBook performance.

Switching tabs between the desktop and other windows makes the computer’s system render every shortcut. The more icons there are, the more of a toll they put on the computer’s system.

Keep the MacBook’s desktop clutter-free. And if you forget where a file is located, use the Finder tool.


It’s not uncommon to buy a MacBook which can be super slow and frustrating. MacBooks are known for their elegance, but in second-hand condition, they’re slow as heck. Although, the above tips may help you to improve your Mac Performance.
