You can mount and unmount drives, volumes, and disks from the command line of MacOS and Mac OS X. For many users, the easiest way to unmount a drive in Mac is to either just drag a volume into the Trash, use the eject keys, disconnect the drive, or use one of the force eject methods.

Syntax:

Neutrino
Options:
- before — Mount the filesystem so that it's resolved before any other filesystems mounted at the same pathname (in other words, it's placed in front of any existing mount). When you access a file, the system looks on this filesystem first.
- after — Mount the filesystem so that it's resolved after any other filesystems mounted at the same pathname (in other words, it's placed behind any existing mount). When you access a file, the system looks on this filesystem last, and only if the file wasn't found on any other filesystems.

type: | Filesystem or manager: |
---|---|
cd | fs-cd.so |
cifs | fs-cifs |
dos | fs-dos.so |
etfs | Embedded Transaction Filesystem (e.g. fs-etfs-ram) |
ext2 | fs-ext2.so |
io-audio | io-audio |
io-pkt | io-pkt-v4, io-pkt-v4-hc, io-pkt-v6-hc |
io-usb | io-usb |

If you don't specify the filesystem, mount tries to determinewhich to use.If it can't figure out which to use, it uses qnx4.
Specify io-pkt for type no matter which ofio-pkt-v4, io-pkt-v4-hc, or io-pkt-v6-hcyou're mounting. |
Description:
Without options, mount displays the current mountpoints.With options set, this utility mounts the block special device or remote filesystem, special, as the specified mountpoint.To mount a real special device, use the -t option;to specify a special-device string (which isn't necessarily a real device),use -T.
Some servers may not support all the mount options, especially with respect to remounting and enumerating. |
The mount utility supports the /etc/fstab file.
Examples:
Mount a QNX 4 filesystem on a hard drive as /mnt/fs:
Mount a device driver for io-pkt*. In this example, devn-ne2000.so is the name of theshared object that io-pkt* needs to load for the driver, not the name of a real device:
If you want to pass options to the driver, use the -o optionbefore the name of the shared object:
Enumerate the hard disk partition table:
This will re-read the disk partition table for /dev/hd0, and create, update or delete /dev/hd0tXX block-special filesfor each partition. This is used in the following two scenarios:
- when the disk driver is used without any automatic enumeration(blk auto=none), or
- when the partition table has been modified (for example, withfdisk).
Mount a CIFS filesystem (fs-cifs must be running first):
Where your name is abc, your password is efg, your CIFS server is node123 with an IP address of 1.1.1.1, the share you want to mount is /C, and the mountpoint you want to use is /ctest.
Mount an NFS 2 client filesystem (fs-nfs2 must be running first):
Mount an NFS 3 client filesystem (fs-nfs3 must be running first):
Mount the Qnet network protocol:
Display the current mountpoints:
Mount the shared object that supports Enhanced Host Controller Interface (EHCI)USB controllers:
Remount the filesystem that's currently mounted at / asread-only:
Remount the filesystem that's currently mounted at / asread-write:

Here’s the answer to another reader request…
According to WIkipedia, “On Apple–Intel architecture Macintosh computers, the EFI partition is initially blank and not used for booting. However, the EFI partition is used as a staging area for firmware updates.” When people look to create non-standard boot environments or attempt to build a hackintosh, the first step is often mounting and modifying the EFI boot partition. Before you read any further, take note: altering your EFI boot partition is not supported by Apple and The Mac Admin takes no responsibility if you render your computer(s) unbootable by mounting and modifying this partition.
To mount an EFI boot partition, follow these steps:
Mount Device Meaning
1. Discover the volume identifier for your EFI boot partition.
Run this command:
The output should look something like this:
Mount Device Machine
In this case, the volume identifier of the EFI partition is disk0s1
2. Create a mount point.
A mount point is a directory where a non-booted volume is mounted. On Mac OS X, mount points are typically created in /Volumes. We can create a directory called efi within /Volumes by running the following command:
Mount Device Mac Air
3. Mount the EFI partition at the efi mount point.
Mount Device Manager
Run the command:
That’s it. Your EFI volume will be mounted. Modify it at your own risk.
