Mac computers and Mac OS X make the most stable combination in the world of computers. Nevertheless, they are not completely protected from some problems. To save yourself from a lot of potential Mac problems, all you have to do is create a bootable Mac OS X flash drive which you can carry around so you can instantly diagnose and repair your computer. This bootable flash drive will serve as your handy solution to Mac emergencies.

  1. You will need a USB flash drive that doesn’t have any data saved and with data capacity of 16 gb above. Connect it to your Mac.
  2. Go to Applications on your Finder menu and open Disk Utility. Choose your flash drive from the list provided on the left portion of the window.
  3. The menu that will appear will have five tabs on it. Select the Partition tab.
  4. For volume scheme, choose 1 Partition. You will be asked to provide a name for the said volume, which you can assign by yourself. For the format, choose Mac OS Extended (Journaled). The size should be set between 15 to 16 gb.
  5. Towards the bottom of the window, there is an Options button. Once the Options window comes out, choose GUID Partition Table. After that, click OK.
  6. Click Apply then Partition. The process will take a few mintes.
  7. Now, insert your Mac OS X installation disk and wait for the window displaying the disc contents to pop up. Once it does, double-click on Install Mac OS X and run the installer. Once you get to the message that goes like “Mac OS X will be installed on…”, click the button that says Show All Disks. Choose your USB flash drive from the list provided.
  8. Click Customize and make sure all items on the pop-up window are unchecked except for “Essential System Software.” Click OK and Install to begin the process, which usually takes around 30 minutes to an hour. After the process is completed, this will use up around 9 gb of your USB drive.

Your bootable Mac OS X installation flash drive is now ready.
