Create a MAC OS X Installation USB

The following steps will show you how to install Mac OSX from a USB drive.

You will need:

  • 1  USB ( At least 16 GB)
  • A Mac OS X Disk Image (.DMG file)
  • 7 Zip (Used to extract the files you will need)
  • TransMac (Used to create an image on your USB drive)

The first thing we need to do is to get to a file called “InstallESD.dmg”.  This is the actual image that we are going to put onto the USB.  You can get this file from an actual installation disk or from a .dmg file that you downloaded previously.  The .dmg file that you download may have various names so don’t worry about what it is called.  Also, if you did download the file from a torrent site please be sure that you are using a clean file and don’t get yourself infected with malware.

  1. Locate your “Mac OSX.dmg” file.
  2. Right click and select “Open With”; Select 7-Zip        (Install 7-Zip if you didn’t already)
  3. Open the folder named “InstallMacOSX.pkg”
    Inside this folder you will see a file names “InstallESD.dmg”
  4. Highlight the “InstallESD.dmg” file and then click the “Extract” button that is just above it.
  5. Select a destination for the file to extract to.  I recommend just putting it on the desktop.  Press OK.

You should now have a file on your desktop (or wherever you extracted to) named InstallESD.dmg.  the next steps will have you prepare your USB drive and then save the image to the USB.

  1. Open “My Computer” or “File Explorer” so that you can see the USB Drive that you want to use.
  2. Right click on the USB Drive and select “Format”
  3. Press “OK”.  It shouldn’t take very long.

Now our USB Drive is prepared.  The next steps will have you save the InstallESD image to the drive.

  1. In TransMac, right click on your USB Drive.  Select “Restore with Disk Image”
  2. If you are sure that you chose the right disk then select “Yes” on the warning screen.
  3. At the next window, choose the file from the desktop (or wherever you saved it) named “InstallESD.dmg”
  4. Press “OK”This will take a few minutes to complete.

Once it is done you should be able to use the USB to boot and install Mac OS X.  You can boot into the USB by holding the “Option” button on your Mac immediately after powering it on.  Once you see the icons on the screen you can release the option button.  Select the USB Drive and it will boot into the installation.

Windows Support Scam

The Scam:

An unknown person will call you and pretend to be Windows Support to try to part you from your money.

How it works:

It starts off with a phone call out of nowhere. They tell you that they are from “Windows Support”, something that doesn’t really exist, and that they are getting error messages from your computer.  They will lead you on a tour through the error logs that your computer generates. They can make it appear as if there is something infecting your computer when there really isn’t anything wrong.

What you should do/not do:

  1. Never accept support from anyone that you did not call yourself, no matter how knowledgeable they sound.
  2. Never click links, download or run software when you are unsure of what it is or where it is coming from.
  3. Immediately hang up on these scammers. Microsoft does not provide this type of support to anyone. In fact if you are not already enrolled in some sort of managed IT services, nobody should be calling you ever to tell you your computer is having problems.
  4. Never give anyone your login or password information. If you have a legitimate need to give out this information you should change it to something generic first and after you are done, change it back to something secure.
  5. If you believe you are infected with a virus,give us a call or contact any legitimate and competent technician.
