A Mac Performance Guide: How to Optimize Your Computer


Have you been a loyal Macbook user but have been experiencing some issues recently? If that is the case, you may be thinking that there is no way around the problem than buying a new computer.

While that is an option, there are ways to improve a computer’s performance without spending much money. Continue reading and find about these methods.

Method #1 – Making More Space on Disk

Lack of drive space is one of the most common causes behind a drop in Macbook’s performance. If you are not careful, you could end up with a lot of junk files like caches or backups.

Look to delete old email attachments and downloads. If there are applications you no longer use, consider removing them as well. You can always reinstall applications again.

A defragmentation is also an option, but it is a bit difficult, so consider reading these guidelines on how to carry it out.

Finally, make use of cloud-based software like Dropbox or iCloud. They are free. Transferring files in clouds will also lessen the burden on the disk and free up more space.

Method #2 – Modifying Internet Browser

Internet browsers are getting more complicated due to all the extensions and add-ons. An average user believes that getting an extension that looks helpful is worth it. And it leads to having too many add-ons and having your CPU overworked because of the browser.

But removing useless extensions is not the only way to improve the internet browser. Sticking to a minimum number of open tabs and keeping the browser up to date will also help.

Method #3 – Using Activity Monitor

Activity Monitor is a great tool to turn to if you are experiencing performance issues. By sorting processes by CPU usage, you will see which apps in the background consume the most resources.

If there are some questionable applications, like ones that consume more than they really should, consider removing them or looking for alternatives.

Method #4 – Decluttering Desktop

A Macbook’s desktop should not be filled with various icons to the point where there is no longer any space left on it. Each icon has to be rendered when you switch between a desktop and another window. And it takes a toll on the CPU.

Instead of keeping it messy, look to organize files in the folders and transfer them to another location of the computer.

Method #5 – Removing Apps from Startup Menu

Every item on the startup menu also burdens the system. On top of that, every time you boot the computer, you need to wait for an app to load as well.

To reduce the number of startup items, go to System Preferences and select Groups and Users. You will have to log in to your profile and go to Login Items. A list of apps will be before you. Untick the boxes and restart the computer. The applications removed from the list will no longer launch on startup.

Method #6 – Turning off Visuals

Visual effects serve no real purpose if you are pragmatic and looking to boost the performance. Go to Dock via System Preferences and untick the boxes from these two:

  • “Animate opening applications”
  • “Automatically hide and show the Dock”

It will not make the most significant difference, but every little bit helps.

Method #7 – Updating and Downgrading the OS

The OS should always be updated to its most recent version. Updates improve stability and performance. And it should not be just the OS. Check the app store regularly and download the newest versions of applications you have installed.

With that said, it is worth mentioning that in some instances, a new OS version does more harm than good, especially on older computers. If you are experiencing a noticeable drop in performance after a new OS update, switch back to the previous version and see whether that will make a difference.

Method #8 – Scanning for Viruses and Malware


Viruses, malware, or any other cybersecurity threat could also be the reason why you are having issues with your Macbook. One cannot know when a virus or malware strikes. That is why having anti-virus running in the background at all times is recommended.

But anti-virus should not be just another idle software in the background. You need to perform regular scans as well. It is better to be safe than sorry. And since scans do not take that long, there is no reason not to have one every week or fortnight.

Method #9 – Cleaning Dirt and Dust

The root of the problem may not stem from the system. It could also be the neglect to clean all the dirt and dust that accumulates over time.

If the Macbook is underperforming and overheating and it is not summer yet, you will most likely have a dust problem. Shut the Macbook and get to cleaning. And turn it into a habit.
