UPDATED ✅ Do you need to free up space on your SSD by deleting unnecessary files on your MacOS? ⭐ ENTER HERE ⭐ and Learn how to do it ✅ EASY and FAST ✅

Although many people do not know it, having files on the desktop of our Mac makes it run slower because you have to upload those documents first and then upload the system.

As well as this example that we mentioned above, there are many other circumstances in which our equipment works slowly. We will focus on one of those situations, and that is when there are too many “junk files”, “documents” Y “programs that we no longer use”.

All these circumstances take up space on our computer and make it work inefficiently. It is for this reason that we have prepared the following post so that you know how to clean your disk, do not miss any details of what we will present to you.

Why is it important to clean our hard drive of unnecessary files?

We recommend cleaning your computer’s hard drive for the following reasons:

to make room

How to clean a hard drive in MacOS and improve its performance

Obtaining more space on our disk will not simply generate something mathematical, this has other much more notable advantages, the main and most logical would be that we could add more information to our Mac.

Another point to take into account, and encourage us to obtain more storage space, is the existence of programs that need to have a certain empty space to be able to carry out the work efficiently, usually occurs with file or backup software.

To improve performance

When we clean the unnecessary registries of our Mac we improve the performance of RAM memorythat is, since there is more space because we clean the garbage, this memory has greater capacity and performance, with this we can open several applications at the same time.

Another analysis is, when the RAM is full, the performance of the computer decreases considerably because the processor becomes slowersince it needs more time to find the data that we are requesting.

To increase disc life

While all Apple components are of excellent quality and last for a long time, when we clean up unnecessary data we help the drive have a better lifespan.

This is so because as the disk is only with the data that we need only your effort is less when doing the work.

To avoid logical errors

The Mac operating system is virtually bug-free so we should not address this issue from the point of view of data storage.

When we talk about avoid logical errors we will refer to the errors that we we can commit, that is, if we had files that are unnecessary, our work would be complicated because we would waste time finding the document we are looking for or we chose the data that has a similar name and it was not the correct one.

This happens very often when we work with spreadsheets, where the only information that varies is the month from one file to another, being able to load the data of one month in a spreadsheet of another date.

To facilitate access to information

This point is closely related to the previous one. because if we have in order all our folders in which the documents are well identified.

In addition, we are careful to eliminate everything that does not serve us, including temporary files. There will come a time when we would not have to have problems when accessing information because we would know where each data is. with which we need to work.

What documents can be considered junk?

Among the documents that can be considered garbage we are going to name the following:

Temporary files

We are going to name with this name those files that they are needed to speed up certain computer processes.

When we browse different Internet sites, or simply when we work with some software, these programs need to have certain data to be able to perform work in the best possible way.

For this they need to install files that once we close the session, they are no longer used. Thereforewhen we delete temporary files our computer processes and our documents will not be in danger because we no longer need them.

That is why we recommend you always delete temporary files.

duplicate documents

As we have mentioned before, when we have our folders or documents out of order, we run the risk of saving the same file or document twice.

This happens very often when we access Internet platforms where we download images or other multimedia files and forward them to another person.

If we do not have that application or that platform well configured, we will duplicate that multimedia filebecause we will surely have it in an image folder of that application and perhaps we can find it in another mailing or similar application.

Programs you don’t use

Many people refuse to clean programs they don’t usebut it is the best recommendation we can make because by taking up space on our disk we are making many components make an effort to be able to do the job and the results will be seen in the performance of the Mac.
