How to Delete Files on Mac When Disk is Full

Most Mac users often complain that they never get a warning or they are never able to know that their disk is full, however this is not true. Your Mac lets you know whenever the disk is getting full, and shows you the continuous warning messages while using the Mac.

But if you keep on ignoring these warning messages then you will start noticing a huge drop in the performance of your Mac and soon you will run out of complete space.

And this is the reason that many users can’t delete files on their Mac because the disk is full, making it more difficult to resolve the problem. For some, the problem becomes even more worsened and they can’t even turn on their Mac as usual.

However, irrespective of the problem you have faced our today’s article will help you on how to free up disk space on Mac. So, without further ado, let’s begin.

How to Free up Disk Space on Mac when the Startup Disk is Full

Although it sounds a bit absurd, the Mac does need a free space to perform any operation, even cleaning the obsolete files, and this is the reason that many at times users can’t delete files on the Mac because the disk is full. This means that if your startup disk is full to the maximum extent then even emptying the trash will become difficult.

So when it seems hard to free up space on your disk then you can follow the below steps:

Start your Mac in Safe Mode

Safe Mode is quite helpful in troubleshooting various issues with Mac that you can’t resolve in the normal startup. When you start your Mac in Safe Mode then your Mac ceases certain applications from running at boot time and also checks the hard disk for any issues and fixes them if found any.

Apart from this, Safe Mode automatically removes certain chunks of cached data that exist on your Mac, and that in turn creates a little amount of free space on the startup disk. So this extra free space comes quite handy and lets you clear the Trash.

If you do not know to boot into Safe Mode then here are the steps below:

  • Shut down your Mac and wait for 30 seconds..
  • Now, press the power button, and then quickly press and hold the Shift. keys on the keyboard
  • Keep holding the Shift key until you see a login screen that reads Safe Mode, at the top-right corner of the screen.
  • Log in with your Mac credentials and start making space on your startup disk

Delete System Junk Files(App Cache)

When it comes to deleting the cache files a user may get confused a bit, and he doesn’t decide whether to delete them or let them pile up. This is because the cache files are there on your Mac in order to speed up the performance of your Mac and the processes running on it.

However, after the end of the process, all you are left with is junk created either by the programs or the system-based processes. Moreover, as we all know that excess of anything is bad, the same is true with junk cache files, if they keep on piling up they will make your disk full and cause all sorts of problems.

And unless you do not clean these junk files on Mac, they will remain on your Mac forever. However, the good news is that you can easily clean junk files on Mac either manually or automatically using a best Mac uninstaller and optimization program. Also, you do not need to worry about the speed, as once you start using an app it will refresh its cache in no time.

To remove cache files, follow the steps given below:

  • On your Mac navigate to Finder > Go > Go to Folder
  • Now type in ~/Library/Caches and hit the Enter key.
  • Next, go inside each folder and delete the files that reside in it. You can also go into the specific folders that are taking most of the space.
  • Repeat the process by going to /Library/Caches.

If you are unsure of deleting any file and consider it as a risk then you can backup that folder on an external drive before deleting it. However, as an alternate option you can clean all your cache with 100% accuracy and with just a click if you use a Mac cleaning software like Cleanup My System.

Delete System Log Files

Another type of junk files that you consider cleaning on your Mac is system log files. Basically, the Mac saves these system log files deep into its memory to be used mainly by the app developers or Mac professionals, to diagnose any of the problems you face in using a certain application or your MacOS. Now, cleaning these system log files doesn’t provide you with a lot of free space but since you are completely running out of space, so every bit of space counts.

To delete system log files on your Mac, go through the steps listed below:

  • On your Mac, open Finder and click Go on the menu bar.
  • Now from the drop down list that appears select the option Go to folder.
  • Now type in the following location /var/log and click on the Go button.
  • That’s it. Here, you can now see all your system log files.
  • Now select all the unneeded files and delete them.

Apart from the location location /var/log, another location where you can check for the system log files is /Library/Logs. Follow the above to navigate to this location and delete all the application logs to declutter your Mac and regain the space on the disk.

And finally do not forget to check the location /Library/Logs/DiagnosticReports, to find and remove the system reports.

Uninstall Unused Apps and Their Leftover Files

We have our Mac filled with lots of applications, downloaded both from third party websites and App Store. But be true to yourself, and answer this. Did you use all of these applications? Also, how many of these programs do you actually need and use?

If you closely look at the applications that are installed on your Mac, you will find that more than half of them are never ever used. Now the problem with these unused applications is that they not only consume the space on your hard drive but also consume the memory and power by running in the background.

So, another way on how to free up disk space on Mac is go through the installed applications and remove them completely from your Mac. Now to remove an application all you have to do is drag that application to Trash. But the problem with this is that it only removes the application, but the app leftover files like app logs and crash reports remain hidden.

Therefore, to remove the app as well its leftover files we recommend you to use an best app uninstaller for Mac. If you look around the web you will find lots of free Mac uninstallers along with paid ones. However, only a few of them live up to their promise.

But after trying various third party app uninstallers for Mac. We find Systweak’s Advanced Uninstall Manager as one of the best Mac uninstallers that not only remove the application but also all the leftover and hidden files associated with the app.

Moreover, apart from completely uninstalling the applications, Advanced Uninstall Manager also helps boost startup time.

Delete Time Machine Backups

Although Time Machine helps us to create important backups, if your Mac is running out of disk space then it’s time to delete Time Machine backups. To get started you should start removing previous Time Machine snapshots that are present on your Mac. So another quick tip on how to free up disk space on Mac is to remove these previous Time Machine Backups.

To do so, you have to first temporarily turn off your Time Machine by following the below steps:

  • Open System Preferences on your Mac and select Time Machine
  • Now on the Time Machine window, uncheck the option that read “Back Up Automatically”
  • Next, wait for a few minutes before the changes take effect. After a few minutes, your local Time Machine snapshots will get removed and a considerable amount of space is freed.
