Delete Temportal Files on MacOS  Step by Step Guide ▷ 2020

Let’s imagine that we have an assistant who saves each of the activities we do during the day on a sheet. At the end of the day that sheet is filled with our data and activities and our assistant saves it in a file.

As time passes we have more and more of these leaves and we begin to realize that they are of no use to us. This is the way temporary files work, are data that is stored in the memory of our Mac according to the different activities that we carry out on our computer.

They are registered from the Internet access to the use of the different applications. We will present you below how you should eliminate these junk files and have a Mac with high performance.

What are temporary files and what are MacOS for?

What are temporary files and what are they for MacOS

Temporary files are all those programs that are used to speed up a certain process. These are used by the operating system and also by different applications that we have installed on our Mac.

The main function of these temporary files is to quickly and accurately deliver all the data that the processor needs to be able to work efficiently according to each of the jobs that we require.

Thanks to these files we can get a very good user experience, since it is based on the agility and speed with which our Mac responds to each of our commands.

Why is it necessary to delete cache and residual files on Apple computers?

Every time we enter the Internet the site through which we navigate installs us, theoretically in Europe they couldn’t do that to us, without us noticing different kinds of programs on our Mac computer. They do this to obtain information about each one of us among other objectives.

When we clean these temporary files, what we are doing is preventing third parties or intruders from having and handling our data in an unscrupulous way.

When we have a lot of data in temporary folders it happens that we are demanding the processor and also the RAM. In other words, when we have little space we can generate internal conflicts between the different directories that the operating system kernel has and also around it.

When we do not have much space on the disk, due to the considerable increase in temporary files, and we have the need to save a large application or program, we can’t do it the right way, or if we can install it, it does not work efficiently since it needs free space on the disk to be able to generate its functions.

When the RAM memory is full, it cannot deliver the true information that many times we require, for example, if we install or need a new program, it probably cannot be installed in the RAM memory because it does not have space and it will do so in a nearby place where it can be run the risk of overwriting that storage disk.

What are the benefits of deleting this type of data from your computer?

When we clean the junk files of our Mac we obtain different beneficial results.

We will have a hard drive with greater storage capacity, connector we will be able to install applications of a larger size than if we were not full.

We can run the antivirus in a correct way and thus avoid generating consumption in the performance of the processor.

When we clean the RAM, what we are doing is freeing this storage unit of all unnecessary information so that the time it will take to find what we really need will be less, thus delivering the precise and correct information to the microprocessor in a much faster way. As a result, we obtain a higher speed in performance.

If we delete the temporary files from our browser also andWe are eliminating or reducing the risks of phishing and any other fraudulent maneuver that they could direct us, because not having our information will make it more difficult for us to fall into their offers.

What programs leave unnecessary files in the operating system that you should remove?

Which programs leave unnecessary files in the operating system that you should remove

The programs that leave unnecessary files on our Mac are:

Installed apps

The apps that we have installed on our computer are intended to provide an excellent user experience, therefore they need files that are generated through each of the interactions we make with them.

Many of these applications do not delete these auxiliary files and leave them in the temporary folder.


The operating system itself generates junk files. As MacOS is one of the systems most chosen by users due to the benefits and performance that it generates in its operation, it needs files for which it has to be based to perform the different commands that we are going to request.

These support files are stored in folders that are useless after the process closes.

Internet network

When we browse the different pages or sites on the Internet, they enter our Mac through the computer, installing small data or files to be able to function correctly and so that we do not lose time in a future re-entry.

Steps to remove temporary files from your MacOS computer

The steps we have to follow to erase junk files on our Mac are as follows, taking into account that we will erase the cache data of the user, the system and the application registry.

To do this, we are going to perform these steps:

User cache

User cache.  Programs leave unnecessary files in the operating system that you must remove

First we will delete these files, so we will need to enter the Finder and follow this guide:

  • We will choose the option “Go to the folder …”
  • We wrote “~ / Library / Caches”
  • At this time there will not be a list with all the folders we have, arranged alphabetically.
  • We select the folder called “Caches”
  • We drag the folder to the trash

We do not have to forget to empty the trash because the files are not deleted if we leave it in it.

System cache and application log

Next, we will deal with the files generated by the operating system itself and by the use of applications.

In order to delete these files we will need to do the following steps:

  • We open a window in the Finder and write “/ Library / Caches”
  • To eliminate the one from the system we will write “/ Library / Logs”
  • We choose “Caches”
  • We dragged it to the trash without forgetting to delete the ones from this place.

As a recommendation, we will tell you that it is useful to make a backup copy since by touching the structure of the operating system we can make a mistake and if we have that copy we can go back a step.

DNS record

We will now deal with deleting the DNS cache from our Mac.

To do this, we will follow these processes:

  • We open the terminal
  • We wrote “Spotlight”
  • We will perform the following command “sudo discoveryutil mdnsflushcache; sudo discoveryutil udnsflushcaches; say flushed”
  • We enter the administrator password
  • We choose the folder
  • We dragged it to the trash can
  • We empty the trash
