- May 08, 2017 A Mac can be started via a USB port, with a USB key or external hard drive, but that device needs to have Mac OSX system installed on it to boot, as well as other requirements. Best bet is to always backup your Mac hard drive with a bootable image created by Apple Disk Utility or a third party utility such as Carbon Copy Cloner.
- Mar 15, 2018 When you connect a Mac-formatted drive to Windows, you’ll be informed that “you need to format the disk in drive X: before you can use it.” Don’t click the “Format disk” button or Windows will erase the contents of the drive–click “Cancel”! Both Windows and Mac OS X have full read-write support for exFAT drives without any.

May 13, 2013 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. Some users are unable to mount CDs and DVDs after applying the Mac OS X 10.3.7 update. Two typical reports of the problem: 'After installing the upgrade to 10.3.7, suddenly my internal Pioneer DVD. When you do that, you should see at least four icons. In my case, I have five because I have Windows installed using Boot Camp. Anyway, the grey MacBook and Recovery 10.11.2 icons are for my internal OS X and the orange OS X and Recovery 10.11.3 are for the version installed on my external drive. Use the arrow keys to select which drive to boot from and then simply press Enter.
Before your computer can use any kind of storage device (such as ahard drive, CD-ROM, or network share), you or your operating systemmust make it accessible through the computer's file system. Thisprocess is called mounting. You can only access files on mountedmedia.

Formats and mounting
Your computer stores data in specific, structured file formats writtenon a piece of media (such as a disk or CD-ROM). Your computer must beable to read the format on this media in order to interpret its dataproperly; if the computer does not recognize the format, it willreturn errors. Also, forcing your computer to work with corrupted orunrecognized formats will cause it to write data incorrectly, possiblyrendering unrecoverable all the files stored on the media.
Mounting ensures that your computer recognizes the media's format; ifyour computer cannot recognize that format, the device cannot bemounted. When media is successfully mounted, your computerincorporates the media's file system into your local file system, andcreates a mount point, a locally available link through which youaccess an external device. In Windows or Mac OS X, themount point is represented by a disk or other icon; in Unixor Linux, the mount point is a directory. Most operatingsystems handle mounting and unmounting for you.
Looking for a way to install and run OS X on an external hard drive? This can be useful for a couple of different reasons. Firstly, it allows you to run another copy of OS X without needing any additional Mac computer.
Also, since you can run a full copy of OS X on the external drive, it can be used for troubleshooting purposes on other Macs or it can be as a kind of virtual OS X. I’ve already written about how you can install OS X in VMware Fusion, but that takes up space on your Mac. Using an external drive, you can save space on your Mac, though it might be a bit slower if you are using USB 2.0.

In this article, I’ll walk you through the requirements and steps to install OS X onto an external hard drive.
Format External Hard Disk

The first thing you’re going to need to do is format the external hard drive properly. The file format has to be Mac OS X Journaled and you have to use the GUID partition map. To do this, open Disk Utility and connect the drive to your Mac.
Under External in the left hand menu, click on your external hard drive and then click on the Erase button. Make sure you backup any data before you erase the drive. When you click Erase, a dialog will pop up where you can configure some options.
Give your drive a name, choose OS X Extended (Journaled) for Format and GUID Partition Map for Scheme. It should only take a minute or two for the drive to be erased and reformatted. Now your drive is ready for OS X.
Install OS X
There are two ways you can install OS X on to your external hard disk: by reinstalling OS X from the OS X Utilities repair screen or by downloading OS X from the App Store and running the installer. I’ll show you both methods in case one isn’t working for you.
The easiest way is to download OS X from the App Store. Once you open the App Store, you’ll see a link on the right for the latest version of OS X (El Capitan as of this writing).
Go ahead and click the Download button to start downloading the installer. Note that if you already have that version of OS X installed, you’ll see a popup message appear asking if you still want to continue or not. Just click Continue.
Once it has been downloaded, just double-click the installer, which will be located in the Applications folder.
Keep clicking past the license agreement, etc., until you get to the screen that asks you which disk to install OS X on. By default, it is set to MacBook.
Click on the Show All Disks button and you’ll see an icon for the different disks and partitions on the Mac. I named my external hard drive OS X and that shows up in the middle.

You can also tell it’s an external hard disk because it uses the icon with the orange hard drive. Click Continue and then follow the instructions to complete the installation. Note that your computer may restart during the install and you don’t have to do anything. OS X will automatically continue installing onto the external hard drive rather than booting up to your internal version of OS X.
At the end of this article, I’ll show you how to boot up to the external hard drive, so skip down if you ended up using the App Store method. Note that by default, the Mac will start booting up directly to the external hard drive until you change it.
The second method to install OS X is to restart the Mac and press and hold the COMMAND + R keys. This will load up OS X Recovery.

The OS X Utilities screen will appear and here you want to click on Reinstall OS X. Again, you’ll go through some basic screens, but when you get to the hard disk screen, click on Show All Disks again.

Using this method, you’ll have to login using your Apple ID and password so that the entire OS X installer can be downloaded off of Apple’s servers. Whichever method you choose, it will take anywhere from 15 to 30+ minutes to install OS X onto your external hard drive.

While OS X is installing, your computer will restart a couple of times. Note that when it finally boots into OS X, that is the version running off your external drive. To switch back and forth between the internal and external drive, you have to restart your computer and hold down the OPTION key.

When you do that, you should see at least four icons. In my case, I have five because I have Windows installed using Boot Camp. Anyway, the grey MacBook and Recovery 10.11.2 icons are for my internal OS X and the orange OS X and Recovery 10.11.3 are for the version installed on my external drive.

Use the arrow keys to select which drive to boot from and then simply press Enter. If you have a newer Mac and a USB drive that supports USB 3.0, everything should run fairly fast. Overall, it’s a fairly straight-forward process and took me less than an hour to get everything working. If you have any questions, feel free to comment. Enjoy!
