    \n
  1. Plug the microSD card into a card reader connected to your Mac. The\n
    boot<\/div><\/div>\n

    volume will be automatically mounted, but it doesn’t contain all the files from the Pi’s primary filesystem.<\/li>\n

  2. Make sure you have Homebrew<\/a> installed (instructions here<\/a>), so you can install the tools you need to mount the filesystem.<\/li>\n
  3. Using Homebrew, install osxfuse and ext4fuse (find out more about the tools on the FUSE for macOS<\/a> website):\n
      \n
    1. \n
      brew cask install osxfuse<\/div><\/div>\n<\/li>\n
    2. \n
      brew install ext4fuse<\/div><\/div>\n<\/li>\n<\/ol>\n<\/li>\n
    3. Use Disk Utility on the command line to find the Raspberry Pi’s partition ID; run\n
      diskutil list<\/div><\/div>\n

      to get output like below:<\/p>\n

      \n\n
      $ diskutil list
      \n\/dev\/disk0 (internal):
      \n   #:                       TYPE NAME                    SIZE       IDENTIFIER
      \n   0:      GUID_partition_scheme                         500.3 GB   disk0
      \n   1:                        EFI EFI                     314.6 MB   disk0s1
      \n   2:                  Apple_HFS Macintosh HD            499.3 GB   disk0s2
      \n   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
      \n
      \n\/dev\/disk2 (external, physical):
      \n   #:                       TYPE NAME                    SIZE       IDENTIFIER
      \n   0:     FDisk_partition_scheme                        *32.0 GB    disk4
      \n   1:             Windows_FAT_32 boot                    66.1 MB    disk4s1
      \n   2:                      Linux                         31.9 GB    disk4s2<\/div><\/div>\n\n<\/pre>\n
      You should be able to tell which drive is your Pi drive by the description (<\/p>\n
      external, physical<\/div><\/div>\n
      ), the ‘Linux’ partition type, and the size of the disk (e.g.<\/p>\n
      31.9 GB<\/div><\/div>\n
      for my 32 GB card). The ID is the<\/p>\n
      disk4s2<\/div><\/div>\n
      in my case, in the<\/p>\n
      IDENTIFIER<\/div><\/div>\n
      column.<\/li>\n
    4. Create a ‘mount point’\u2014a folder on your Mac where you will ‘mount’ the Linux partition so you can read data from it:\n
      sudo mkdir \/Volumes\/rpi<\/div><\/div>\n
      (<\/p>\n
      sudo<\/div><\/div>\n
      requires you to enter your Mac account’s admin password, since it performs actions with elevated privileges\u2014enter your password when prompted.)<\/li>\n
    5. Mount the drive using\n
      ext4fuse<\/div><\/div>\n
      :<\/p>\n
      sudo ext4fuse \/dev\/disk2s2 \/Volumes\/rpi -o allow_other<\/div><\/div>\n<\/li>\n<\/ol>\n
      The<\/p>\n
      -o allow_other<\/div><\/div>\n
      is required to make sure the mounted disk is readable by everyone (and not just the<\/p>\n
      sudo<\/div><\/div>\n
      \/<\/p>\n
      root<\/div><\/div>\n
      user). See this issue: Unable to open ext4 mounted partition on El Captain<\/a>.<\/p><\/blockquote>\n
      Now you’ll see the<\/p>\n
      rpi<\/div><\/div>\n
      volume mounted in the Finder. You can open it and read from it just like any other disk, card, or flash drive you connect to your Mac.<\/p>\n
      Once you’re finished, make sure you safely unmount the disk, by either ejecting the disk in the finder, or running<\/p>\n
      sudo umount \/Volumes\/rpi<\/div><\/div>\n
      in Terminal. After that, you can unplug the card and put it back in your Pi, where it will be ready to do more awesome Pi things!<\/p>\n","protected":false},"excerpt":{"rendered":"
