			=Recovery=

			Things happen. it may be that your mac acts up and you need to troubleshoot the boot process and recover your data.

			One way to backup your data is to plug in a USB drive and boot into recovery mode with pressing CMD+R while booting.
			From there you can use the Disk utility to check the integrity of the disk. After that you can close the disk utility and open a Terminal and use unix commands to troubleshoot and also to backup your data.

			Note, another way to enter a terminal would be booting it a single user mode (Ctrl+S down while booting), but mounting a USB drive or recognizing it might proove to be a challenge. In the Recovery moe it was mounted automatically, and you can also verify its integrity before the backup, if you wish.

			There are ways to do backups Macos way, however the story below is how to do it Unix way using cp command. Another way would be to use rsync, but that was not available for me in the recovery mode.

			Tasks:
			* You may want to make your file system read and writeable. Optionally check it for defects before:
			/sbin/fsck -fy
			/sbin/mount -uw /
			Mount the USB drive (unless automounted)
			* Find the USB disk device. The usb disk is likely to be the last one, e.g. disk21s1
			ls /dev/disk*
			* Make a directory for the mount point:
			mkdir /Volumes/usbdisk
			* Determine the type of the filesystem on the USB disk (NTFS or FAT32 or ...)
			fstype disk21s1
			* Mount the disk on the mount point, so you can access its filesystem with the regular commands

			== Resetting a new user account on macos==
			From a single user mode (press Ctrl+S while booting)
			mount -uw /
			rm /var/db/.AppleSetupDone
			shutdown -h
			This will:
			* Re-mount the internal hard drive with write permission
			* Remove the Mac setup file. This is the file that OS X checks to determine if the system is already set up.
			* Shutdown the Mac
			Then restart and you should be prompted for a new user account.

			* [http://macports.org MacPorts] that you may want to install to ease the path to other open source software. Mind, that many of the packages will compile from source and drag all the requirements with them. This will take time and space.

			* [http://brew.sh/ Homebrew]. Mostly easier than macports, but fewer packages, although the macports cound several versions of applications as separate packages. Homebrew is striving to depend on native OSX resources when available.

			== Encript folders with EncFS ==

			EncFS is a cross platform virtual file system that mounts a volume over one directory and encrypts everything written to it to another physical directory.

			EncFS is installed as follows:

			# Install OSXfuse
			# Install EncFS
			brew install encfs

			# Use Encfs to mount an encrypted volume
			encfs ~/Dropbox/Private.enc/ ~/Private/
			# or with a custom volume name
			encfs ~/Dropbox/Private.enc/ ~/Private/ -- -o volname="Dropbox private"
