How to create Mac OS X bootable USB installation media
Before you can use TransMac, you may first need to partition your USB flash drive with a GPT partition, as a normal MBR partition may not work. To do this, you’ll need to use the Diskpart command-line utility on Windows.
Setting up GPT partition
Use these steps to set up a USB drive with a GPT partition:
- Open Start on Windows 10.
- Search for Command Prompt, right-click the top result and select the Run as Administrator option.
- Type the following command to open Diskpart and press Enter:
- Type the following command to determine the USB flash drive and press Enter:
- Type the following command to select the storage and press Enter:Quick tip: The

command as an example, but you have to replace 1 with the number of the flash drive you want to use. - Type the following commands to delete everything from the USB thumb drive and press Enter:
- Type the following command to convert the drive into a GPT partition and press Enter: https://titanever676.weebly.com/itau-empresas-app-mac.html.
- Type the following command to select the new partition and press Enter:
After you complete the steps, the USB flash drive from MBR to GPT format, you can use the steps below to create a bootable USB installation media to install Mac OS X.
Creating USB install media
Use these steps to create a bootable media to install Mac OS X:
- Download and install a copy of TransMac.Quick note: TransMac is a paid software, but it has a 15-day trial solution, that give us more than enough time to move the DMG files to the USB drive from Windows. (If you want to support the developer, you can purchase the full version.)
- Insert the USB drive that you’ll use to fix your installation of OS X. (Remember that all the data in the USB will be erased. Make sure you take off any important documents.)
- Right-click the TransMac software icon and Run as administrator. (You’ll be prompted to Enter Key or Run, because we’ll be using it once, click the Run option.)
- On the left pane, you’ll see all the Windows PC drives listed, right-click the USB drive that you’re intending to use to reinstall Apple’s OS X and select the Restore with Disk Image option.
- In the warning dialog box, click the Yes button.
- Use the Restore Disk Image to Drive dialog box to browse for the DMG file with the installation files for Mac OS X Yosemite in this case, and click the OK button to create a bootable USB of the operating system.Now, you’ll have to wait a long time. No kidding. It could take one or two hours to complete the process depending on your computer and other variables.
Once your bootable USB installation media is ready, remove it and insert it into your Mac, power it on, holding down the Option key, and select the USB you just created to reinstall Mac OS X.
If you’re having issues trying to create a bootable media, you can get a USB flash drive that comes with Mac OSX ready to install.

For You
Update: Go to Bootable USB Flash Drive to Install Mac OS X 10.10 Yosemite if you want to install Mac OS X 10.9 Mavericks or Mac OS X 10.10 Yosemite instead. The instructions below will not work for Mac OS X 10.7 Lion or later versions. Spell point variant 5e dmg.
I thought it would be useful to put the Mac OS X 10.6 Snow Leopard installer on a USB flash drive. It would be faster than reading from a DVD. I can use it with a Macbook Air or Pro Retina which do not come with a DVD drive. And the USB flash drive is more portable and robust than a DVD.
Note: I’m doing the following on a Macbook running Snow Leopard. The resulting USB flash drive will boot on Intel-based Macs only. If you want to boot the USB flash drive on a PowerPC-based Mac, please see the comments.
Create a DMG file
You can skip creating a DMG (Disk iMaGe) file if you clone directly from the Snow Leopard “Mac OS X Install DVD” disk to the USB flash drive. I just wanted a DMG file for speed and convenience; in case I need to clone to a dual-layer DVD or to another USB flash drive.
- Insert the Snow Leopard 10.6 “Mac OS X Install DVD” disk into the DVD drive.
- Run the “Disk Utility” application (under the “Applications/Utilities” folder).
- On the left-hand pane, you will see “Mac OS X Install DVD” appear under the DVD drive when the DVD is mounted. A “Mac OS X Install DVD” disk icon will also appear on the desktop.
- If you don’t see the “Mac OS X Install DVD” even after waiting for a while, try closing and starting the “Disk Utility” application again.
- On the left-hand pane, select the “Mac OS X Install DVD” by clicking on it.
- Click on the “New Image” icon, located in toolbar at the top.
- Select the location to save the DMG file (“Mac OS X Install DVD.dmg”) to. Leave the defaults of “compressed” for “Image Format” and “none” for “Encryption”.
- Click on the “Save” button. The DMG file creation can take 20 minutes or longer.
Why wont dmg files open. Format USB Flash Drive as Mac OS X Bootable
You will need an 8GB USB flash drive. Format it as a Mac OS X bootable drive by following these steps:
- Insert the USB flash drive.
- Run “Disk Utility”.
- On the left-hand pane, select the USB drive (not the FAT32 or other partition under it).
- Click on the “Erase” tab, select “Mac OS Extended (Journaled)” for “Format” and input a name like “Snow Leopard Install USB” (or anything because this will be overwritten later).
- Click the “Erase…” button and then the “Erase” button. This format operation will take less than a minute to complete.
- Once the format completes, make sure that the USB flash drive is selected in the left-hand pane. In the bottom pane, check that the “Partition Map Scheme” is set to “GUID Partition Table” (which means it is Mac OS X bootable). Under Snow Leopard, formatting as “Mac OS Extended (Journaled)” appears to select the “GUID Partition Table” scheme by default.
- If you are not running Snow Leopard and the “Partition Map Scheme” is not set to “GUID Partition Table”, please repeat steps #1-3 above and then the following alternative steps:
- Click on the “Partition” tab, select “1 Partition” under “Volume Scheme”, ensure “Mac OS Extended (Journaled)” is selected for “format”, and leave the name alone or change it to be anything (it will be overwritten later).
- Click on the “Options” button and ensure that “GUID Partition Table” is selected. Click OK.
- Click the “Apply” button and then the “Partition” button. This format operation will take less than a minute to complete.

Restore the DMG file to the bootable USB flash drive: Driving simulator free download for android.
- Locate the “Mac OS X Install DVD.dmg” file that was created earlier. Double-click on it to mount and launch it. You will see a “Mac OS X Install DVD” disk icon appear on the desktop. You can close the “Mac OS X Install DVD” application window that was also opened.
- Insert the Mac OS X bootable USB flash drive that we created above.
- Run the “Disk Utility” application. On the left-hand pane, you should see both the USB flash drive and the mounted DMG file.
- On the left-hand pane, select the partition under the USB flash drive.
- Click on the “Restore” tab and drag that same partition (under the USB flash drive) to the “Destination” field (you will see a green plus mouse icon appear when you drag over the field).
- If you cannot drag the “Mac OS X Install DVD” partition under the DMG file to the “Source” field (on Snow Leopard, the green plus mouse icon won’t appear and no action is taken on the drop), you can instead right-click on the “Mac OS X Install DVD” partition and select “Set as source”. The “Source” field will then be filled with the partition name.
- Even though you can click on the “Image…” button and select the DMG file, when you do the restore, Disk Utility will throw a “RESTORE FAILURE” error with the message: “Could not find any scan information. The source image needs to be image scanned before it can be restored.”
- If you are cloning directly from the “Mac OS X Install” DVD, you can just drag the partition under the DVD drive to the “Source” field.
- I left the “Erase destination” box checked. With this box checked, the restore operation took about 25 minutes. When this box was unchecked, the restore operation reported that it would require 4 hours.
- Click the “Restore” button, then the “Erase” button, and input your Mac OS X administrative password.
- When the restore completes, you may see two “Mac OS X Install DVD” application windows appear, the first from the mounted DMG file and second from the USB flash drive. There will also be two “Mac OS X Install DVD” disk icons on the desktop. Also, notice that the partition under the USB flash drive is now named the same as the source, “Mac OS X Install DVD”.
- Select the USB flash drive in the left-hand pane. In the bottom pane, double-check that the “Partition Map Scheme” is still set to “GUID Partition Table”.
- If you are not using Snow Leopard and find that the “Partition Map Scheme” is no longer set to “GUID Partition Table”, you may need to redo the restore. Reformat the USB flash drive (per the alternative instructions above) and before doing the restore, uncheck the “Erase destination” box. I fear that the “Erase destination” function may modify the partition map scheme to be something other than “GUID Partition Table”.
