Why is my MacBook running slow?

There is no easy answer to this question. It might be due to an outdated operating system or a full hard drive, especially if you are using an older model of MacBook. The Mac might be slow because you have opened too many files on your desktop, or you have your browser has too many extensions installed.

There could be one reason, a combination of two or three, or possibly something else. Sometimes, you can check the signs that tell where exactly the problems lie. At other times, you can’t just figure out what is slowing your MacBook. In that case, it is wise to look for professional MacBook repair services in Surrey.


However, below are some of the common reasons why your Mac is running slow-

Too many background processes

Sometimes, a MacBook does not notify if a specific application or process is eating up most of its memory. This happens when the background processes are buggy or the applications installed in the system are crashed.

The Operating system or apps are outdated


Sometimes, the reason behind your MacBook running slow is you are using outdated software. Make sure to check if the OS, as well as all the installed applications, are updated. New apps and OS feature security patches to protect the device against bugs and run faster.

There is Malware on your MacBook


Though unlikely, MacBook devices can get virus attacks too. One way to keep away from malware attacks is to keep an eye on what types of applications can be installed on your MacBook. Allow applications to be installed from the Mac App Store. Besides, you can scan your MacBook with a free malware-scanning tool to ensure a virus infection is not causing your Mac to slow.

Visuals that are demanding


While Apple eased up on the demanding or heavy visuals that used to appeal to MacBook users. Still, macOS has a variety of visual effects that are heavy for an old Mac model. Not only do these visuals use resources, but they also affect battery health.

These are just a few possible reasons why your MacBook might be running slow.
