What you should know about the cache on the Mac
Before cleaning the cache of your Mac you must first know what you are doing specifically. Below we detail all the details that you should know about this entire procedure and the doubts that may end up arising.
What are cache files on a Mac?
When an application is used or a web page is visited, a trace is always left in the form of files. This includes images, scripts, and temporary files as well as other data that allow for a faster load momentarily. The problem with these files is that they are generated in the background and you yourself do not realize that they are being created constantly. In the long run this is a severe problem in many ways, the most important being related to the space it occupies within the storage disk.
Another of the big problems that exist is that there is a lot of ignorance with the function that these files have. The truth is that it can be called ‘garbage’ that is generated with each of the searches that you carry out that do not have a real function. Many of these files, except for the most recent ones that are generated, they do not fulfill any type of function within the operating system. All they do is disturb and take up valuable space that in some cases makes it impossible to download other files locally or even install software updates.
Is it safe to delete them?
When it comes to deleting any internal file from the macOS system, there is always a fear. The fear of deleting something important from the ‘forbidden’ folders makes you fear that your computer will be completely corrupted. Nothing could be further from the truth. These files have the function of faster loading of a specific web address or having the login details. For example, when you are in a social network such as Twitter and you are logged in, the fact that every time you enter it is logged in, it is a result of the cache.
The moment the cache is completely removed this is also completely deleted. The page in question will load more slowly and you will not be logged in. This happens especially with the most recent cache, which is the only one that has any kind of utility. If you want to be much more selective you can delete those temporary files that are older so as not to suffer these consequences. But the most relevant thing about this is that clearing the cache is totally safe and will not end up corrupting the operating system by deleting it. In the long run it should be considered a form of Mac maintenance.
Process of clearing the cache
When it comes to clearing the cache on a Mac, keep in mind that it can be generated in various parts of the system. The first one is in the native browser itself that is used daily. But it must also be borne in mind that all applications that are used daily as a simple text manager also end up generating these types of files temporary.
Clear Safari’s temporary memory
The web browser is undoubtedly one of the most conflictive points when it comes to generating cache. They are many websites that are visited on a day-to-day basis and that is why a large number of temporary files are generated. In the short term they do not pose any type of problem obviously but over the months the accumulation of files that weigh a few KB in the end can mean several GB of totally wasted use.
Safari doesn’t make it easy at all to clear the cache. First-hand includes it within the entire browsing history, something that you may not want to delete. To make it much more specific, the special developer permissions must be activated as follows:
- Open Safari on your Mac.
- In the top toolbar choose ‘Safari’.
- Click on ‘Preferences’.
- In the menu that appears, select the ‘Advanced’ section.
- Check the box that says ‘Show the Development menu’.
- Now in the upper toolbar a new section will appear next to ‘Bookmarks’ called ‘Development’.
- Click on this section and select ‘Empty cache’.
At this point you must close and restart the Safari browser so that the deletion you have made can be appreciated. As we have mentioned before, from this moment all the logins will be deleted and you will notice that the web pages begin to load more slowly at first. It should be noted that the passwords as such are not deleted since they are stored in the iCloud keychain, which in this case does not end up being modified.
Delete temporary files from applications
Another possibility that exists is to delete the cache of the applications you use on a day-to-day basis on your Mac. All these files must be deleted manually by accessing internal system folders. You must access the route ~ / Library / Caches found inside the main storage unit. To access you simply have to enter the Finder and at the top follow the Go> Search sections.
At the moment a folder will be loaded inside which you will find numerous subfolders. Each of these subfolders has the names of each of the applications that you have installed on your computer. Deleting everything inside will leave the application without any type of cache. But you have to be very careful in this regard, since if you have some kind of project active in any application, it may end up being deleted. Some applications use the cache to store important information in this regard, and it is because in this case you should always choose to delete the oldest cache while keeping the one that is more recent.
Use of third party applications
If you want to make this deletion process much easier and safer, you can find third-party applications to do them. When executing its internal analysis, it is possible to search among all your folders for files that are considered temporary to proceed to delete them. It is what is considered ultimately general maintenance tasks on any computer that always promise to improve device performance. In addition to general cleaning, other extra features are also offered.
These applications can allow you not to accidentally delete something that should not be deleted. It also removes the task that can be so scary that is to enter the internal files of your Mac since it will detect them and you with a single button will erase all this information in a simple way. But not only from the applications but you can also delete the one from all the browsers you have installed as well as the Mail application which also generates a lot of multimedia files.
