It is very important to keep some free space on your mac for several reasons. We'll show you some reasons why you want a little more free space on your Mac than you normally do.Mac Slowing Down
If you don't have enough space on your mac, it can be much slower in several cases. When you're on the internet or working on it, it can appear a lot slower. Most of the time, however, the whole system is slower, so it's always better to keep your space free.Sofwtare Update
The next thing is to update the system. For this you usually need a few GB of free space on your disk as each new update adds some more files.
System updates are one of the most important things, so it's definitely a good idea to have space for it.Startup Problems
Another possibility is that your Mac will behave strangely and turn on very slowly. This can also be due to the fact that you have many applications set to turn on immediately on boot and therefore the system also takes much longer to load.
However, lack of space is also a problem and can cause the exact same thing, namely a very slow start of your mac, which can take up to several minutes to load.Temporary Files
Macs use storage for temporary files. It can take up a lot of storage when you are doing a intensive task such as editing a movie.
It’s always better to keep some storage free to allow your Mac to function properly with the temporary files. If you don't your Mac may stop working when you do some intensive tasks at it.
Keeping your system clean is definitely necessary, even in an orderly fashion. In fact, if you clean your Mac and take care of what you store on it, it will always be a lot faster, plus you'll keep everything nicely organized.
It's good to know where your folders and documents are when you need to use them, and that's why it's also very convenient. Organizing your folders is very important and when you no longer need a document, folder or application, you can simply delete it.
And for these reasons in particular, it's clear why you want to keep your Mac space more free. If it's also very crowded it will work a lot more and so its lifetime may not be as high as you would expect.
