====== Mac Boot Problems ======

{{section>:mac:boot_options}}

===== Steps to Resolution =====

==== Backup important files ====

  - boot into single user mode (<apple> + s)
  - run /sbin/fsck -fy
  - run /sbin/mount -uw /
  - make a directory in /Volumes (mkdir /Volumes/DirName)
  - mount usb drive /sbin/mount_msdos /dev/disk1s1 /Volumes/DirName (disk1s1 is my external drive and the specific partition I want to mount
  - use rsync to backup files (rsync -av /folder/to/copy /Volumes/DirName (will make a "copy" folder in the DirName directory)

<note important>make sure to unmount your external drive, and then remove the DirName directory (it should be empty after unmounting) - use rmdir /Volumes/DirName (it will complain if the directory is not empty)</note>
