There are four ways to view Mac storage space: 1. View the total capacity and classification usage through the Apple icon → About this machine → Storage; 2. Right-click the disk in the Finder → Show the introduction to view the remaining space; 3. System settings → Privacy and Security → Storage Space → Management View detailed classification and clean files; 4. Use third-party tools such as DaisyDisk to visually analyze storage occupancy.

Want to see how much storage space your Mac has left? In fact, the method is very simple, and there is more than one. You can quickly view the overall usage at any time and can also see in-depth which files or applications account for the majority.

View the total storage directly in "About this machine"

The most direct way is to go through the Apple icon in the menu bar → About this machine → Storage . Here you will display the total capacity and used space of your Mac, and you will also list how much space you used in the system, app, photos, videos, etc. by category. Although this interface is simple, it is enough to quickly determine whether it needs to be cleaned.

If your Mac is macOS Ventura or newer, this interface will be more detailed, such as telling you if there are too many "other" files that take up space (those may be logs, caches, or old files you forgot).

Use "Findor" to check the remaining space of a disk

Sometimes you want to see an external hard disk or a partition other than the boot disk. At this time, you can use Finder → select the corresponding disk in the device list on the left → right click → display the introduction , and you can see how much space there is left on this disk.

This method is suitable for you when you plug in a USB drive or a mobile hard drive and want to know if you can copy something in.

Check detailed storage analysis in system settings

If you want to know more about what exactly is eating up your space, you can open System Settings → Privacy & Security → Storage Space . There is a "Manage" button here. After clicking in, the system will help you sort out the usage of apps, photos, email attachments, local time machine snapshots, etc.

You can also be here:

• Delete large files or apps that are no longer needed
• Clean up cached data in "Other" types
• Automatically manage some files using the Optimize Mac Storage feature

However, it should be noted that the "other" category sometimes contains a lot of fragmented files, and manual cleaning may be more troublesome. It is recommended to use the help of tools.

Third-party tools can be seen more clearly

If you think the functions that come with the system are not intuitive enough, you can use some third-party software to help, such as DaisyDisk, CleanMyMac X or OmniDiskSweeper. They can visually show which folders take up the most space, and can even delete unnecessary content directly inside.

DaisyDisk is a good example. It uses a pie chart to display the size of each folder. Click in to see which directory is particularly large. This kind of visual feedback is quite friendly to obsessive-compulsive disorder.

Basically these are the methods. I check it occasionally, and I will not be in a hurry when I encounter insufficient space.
