Mac OS Sierra and High Sierra occupies 95GB on the MacBook Pro 2017 128GB Edition. How to Clean

disk-spacemacbook promacosmacos-highsierramacos-sierra

I am an iOS developer. I am using a 2017 MacBook Pro with 128GB disk space to do my job (company laptop 😭 ). But recently, I found I don't have enough space to build my app, switch Git branches. It notices me the disk space does not have enough to do so.

I have used Disk Docter Pro to clean some caches, Developer files. But the OS disk size is still over 95 GB.

How could it happen? And, how to resolve this issue?

  • The window you showed gives only a basic view of the disk usage. For more thorough inspection, use the following command:

    du -sh <folder>/*
    

    Note 1: Use sudo for folders where your user does not have sufficient permissions, e.g.

    $ sudo du -sh /*
     41G    /Applications
     17G    /Library
      0B    /Network
    7,1G    /System
    1,2T    /Users
    

    Note 2: Add <folder>/.* to include hidden files, e.g.

    $ du -sh ~/* ~/.*
    592M    /Users/Mirek/Applications
    8,6G    /Users/Mirek/Desktop
     14G    /Users/Mirek/Documents
     19G    /Users/Mirek/Downloads
     32K    /Users/Mirek/.DS_Store
      0B    /Users/Mirek/.TemporaryItems
    687G    /Users/Mirek/.Trash
    

    Or you can use a GUI application like DaisyDisk.
