The problems of insufficient hard disk space in Mac can be solved by cleaning up "other" types of files, uninstalling large applications, and deleting photos and videos. Specific methods: 1. Use the system "management" function or third-party tools to clean the system cache and logs, which can free up 5~30GB of space; 2. Uninstall large-scale applications such as infrequently used development tools and design software; 3. Clear the most recent deleted items of the photo, export old photos and compress videos to reduce occupation, and clean up the pictures and video data in the chat tool. Regular inspections and timely sorting are the key.
The system is stuttering and slow startup, which is often because your Mac hard drive is almost full. Especially for solid-state drives equipped with macOS (especially 256GB models), once the available space is less than 10%, the system will run significantly slower. Don't rush to change the hard drive. Try these practical methods first to easily free up a few GB or even dozens of GB of space.
Clean up disk space occupied by "other" types
Among the Mac storage categories, the "other" category is the most troublesome, which may be mixed with various hidden files, logs, caches and residual data. Open "About Native Machine - Storage". If you see that "others" take up dozens of GB, it means that there is a lot of garbage hidden in the system.
You can do this:
- Use the "Management" function that comes with the system: after entering the "Storage" page, click "Manage" and you can see that there is a lot of cleanable content under "System Data", such as the old Time Machine local backup, iOS firmware cache, etc.
- Manually clean cached files: Go to the
/Users/用戶名/Library/Cachesfolder to delete the temporary files inside (don't worry about mistaken deletion, the system will automatically rebuild). - Assisted with third-party tools: DaisyDisk and CleanMyMac can help you quickly scan and clear useless data in "other" categories.
This type of operation usually frees up space ranging from 5 to 30GB, depending on your usage habits.
Uninstall large applications that are not commonly used
Many people forget that the software is still on the computer after installing it. Especially for "big guys" such as development tools, design software, and video editors, one can eat up several GB or even more than ten GB of space.
We recommend that you check regularly:
- Go to the "Applications" folder and see if there are any software you haven't used in months
- Right-click "Move to Trash" to uninstall (some software also comes with plug-ins or configuration files, which can be completely cleared with AppCleaner)
For example, Adobe Creative Cloud suite, Parallels virtual machines, Xcode and other common "space players".
Cut the space taken up by photos and videos
If you enable iCloud photo synchronization and choose "Optimized storage space", the thumbnails and some original images will still occupy local space although the photos of your phone look in the cloud.
It can be handled like this:
- View the Recently Deleted Album in the Photos app and clear photos you no longer need
- Export some old photos to external hard drive or cloud drive, and delete them locally
- If you do not need to retain the original video, you can transcode the 4K video to 1080p and save it
In addition, the pictures and videos in chat tools such as WeChat, QQ, and Telegram are also easy to accumulate a lot of data, which is worth cleaning up specifically.
Basically, these methods do not require too complicated operations, the focus is on regular inspections and timely cleaning. Some space problems are not because you have installed a lot of things, but because you haven’t sorted them out for a long time and slowly they are covered up.
