5 advanced tips to free up storage space on your Mac


After a period of use, make sure the storage capacity in the computer Mac Yours will fill up gradually. For those using 500GB, 750GB or 1TB large capacity hard drives, this shouldn’t be too much of a concern (although it will fill up sooner or later), but for those who are attaching an SSD for Mac For me, the capacity story is extremely important. When the storage drive is full, you have tried deleting all your personal files and unused applications but it still doesn’t free up much. free space. If you are in that situation, check out the 5 tips in this article.

Clear cache file

Cache can be roughly translated as “caching memory”. In OS X, Apple arrange a folder called Caches to allow programmers to temporarily store application data here for many different purposes, such as saving app configurations, speeding up content loading. content… After a period of use, this folder will fill up and the amount of HDD/SSD space it occupies will increase.

To delete things that are no longer in use, go to the Desktop, press Command + Shift + G. In the new dialog box that appears, enter the line ~/Library/Caches/ and then press Enter. A Finder window will open right in the Caches folder. But by default OS X does not show us the size of the folder, so you have to go to the View menu > Show View Options (or press Command + J). Check the box for “Calculate all the sizes”. Wait a moment for Finder to finish calculating the folder size.

Continue to switch the Finder window to an easy-to-follow list view by clicking the four horizontal stripes icon as highlighted in the image above (or pressing Command + 2). Now you will see the cache folder with the largest capacity at the top and gradually decreasing. Take a look at the things you don’t need to delete, maybe the cache folders of old applications, for example. Note that you have to be careful, if you delete the wrong things you use, it will be very troublesome. You can also delete certain files in the folder only (for example, I only deleted Adobe Raw cache files from March and earlier).

Erase voice data from your Mac

For SSD users like me, free space is very important (because I don’t have the money to buy a large capacity drive), so I always find a way to delete all the files I don’t need. Among them are the files that OS X uses to convert text-to-speech (text-to-speech) and they also take up quite a bit of space.

To delete text-to-speech files, do the following: run the Terminal application (can be found in the Applications folder > Utilities > Terminal or press Command + Space, type Terminal). Once the Terminal window appears, type (or copy-paste) the following two commands one by one:

cd /System/Library/Speech/
sudo rm -rf Voices/*

After running these two command lines, my two machines have about 300MB and 500MB more free. That’s a pretty big number. Enough to hold dozens more text files and a few more apps.

In case you USE text-to-speech, make sure you only delete files belonging to unused apps in the /System/Library/Speech/Voices/ directory. But I think the number of you using text-to-speech is not much.

Delete Steam’s support folder

Steam is a widely used gaming platform today. I use Steam, and I know many other friends who are also using Steam to play games on Mac. If you are too, check it out tips later to free up memory.

First, go to Finder, press Command + Shift + G, then type ~/Library/Application Support/ and then press Enter. In this folder you will find a smaller folder called Steam and there are many files of games that you no longer play. To see the size of the folder, you also follow the instructions in tip 1, that is, press Commad + J, select the Calculate All Sizes box. You’ll see which games are taking up storage space. But remember to only delete the data of the games that are no longer playing, and if you only have 1-2 games installed in your device, then you don’t need to delete it.

Clear QuickLook system logs and cache files

Logs are files used to record the activities of something and it is often used to log errors, monitor app performance. The number of logs as well as the log size will increase even though the logs are mostly just plain text files. However, for most ordinary users, we don’t need to read these log lines to do anything. So we can completely delete them safely without worry.

To clear the log, run Terminal, then enter the following command:

sudo rm -rf /private/var/log/*

Note that the machine will ask you to enter the password. If necessary, you can perform log deletion about once a month because when deleted, applications and services will regenerate the log, and also over time they grow again. I deleted the log after 3 months of using the device and got up to 2GB of free space.

In addition, you can clear the QuickLook feature cache. It is a feature to preview the content of a certain file when you press the Spacebar key. For example, select an image file on the desktop, press Spacebar and you will see its preview image, and if you select an MP3 file, you will hear the music. And to work, QuickLook needs to use the cache and we can completely clear it by running Terminal, entering the following command (Terminal will also ask you for a password):

sudo rm -rf /private/var/folders/

Disable SafeSleep on Mac

In 2005, Apple released a feature called SafeSleep. Basically, this is a “winter” mode (called Hibernate in Windows) and it has the ability to save the operating state of the Mac. That way, when you start up, your Mac will be back to where you left off, even if the battery is dead or you shut down completely.

In OS X Lion, Apple continues to introduce two new features, Autosave and Resume, with the same operation as SafeSleep. Therefore, disabling SafeSleep does not affect Autosave and Resume, but can help you free up a few GB of space. If you often plug in the charger when the device is almost out of battery, but do not let the battery drain completely, use this trick.

To do this, launch Terminal, then enter the following command to disable SafeSleep.

sudo pmset hibernatemode 0

Continue to enter the following command to delete the drive image files that SafeSleep has created

sudo rm /var/vm/sleepimage

If you have a problem and want to enable SafeSleep “let it heal” type in Terminal the following line:

sudo pmset -a hibernatemode 3

Some other things you should do when you need to free up space for Mac

  • Delete trash. I see that there are many friends, especially many of you who are new to Mac, refuse to delete trash, and when you can delete it, you will find 2-3GB free, some people even more than that depending on the size of the deleted file.
  • Delete apps you don’t use. You can use the cleanmymac app to help you remove the application more cleanly.
  • Delete *.dmg files that are no longer in use because they are already installed on your computer.
  • Consider copying things you rarely use or don’t use to an external hard drive. You have many benefits when doing this: when several computers, the data is not lost, if the machine fails, there is still something to copy back.
  • You can use services like Dropbox, Box, SkyDrive to save files that are no longer in use, the benefit is that you can access them anytime and anywhere (all your important data, I save it all to the cloud, save it to the cloud). add a copy on an external hard drive). After moving to the cloud, delete the data on the device.
  • Clear browser cache. This will vary from browser to browser, but in general you will need to go to your browser’s Preferences > Privacy > Cache/Cookie/History data (or equivalent words)
