Mac OS X offers a built-in way to create a bootable drive from another Mac’s hard drive. This process, known as target disk mode, turns your external drive into an emergency boot device for another Mac. Here’s how to set it up.
- Target Disk Mode is a mode that allows you to use your Mac as an external hard drive
- To enter Target Disk Mode, power on your Mac while holding down the T key
- Once you’re in Target Disk Mode, connect your Mac to another Mac using a Thunderbolt cable
- The other Mac will then be able to access the files on your Mac’s hard drive

Can You Install Macos in Target Disk Mode?
Yes, you can install macOS in Target Disk Mode. However, there are a few caveats that you should be aware of before attempting to do so.
First and foremost, it is important to note that Apple only supports installing macOS in Target Disk Mode on Macs with Intel processors.
If your Mac has an AMD processor, you will not be able to install macOS in Target Disk Mode. In addition, Apple only supports installing macOS in Target Disk Mode on Macs that are running the latest version of macOS. So, if your Mac is running an older version of macOS, you will need to update it first before attempting to install macOS in Target Disk Mode.
Another thing to keep in mind is that when you install macOS in Target Disk Mode, all of the data on the target drive will be erased. So, if you have any important data on the target drive that you want to keep, make sure to back it up first. Finally, because installing macOS in Target Disk Mode requires erasing the target drive, it is also recommended that you have a backup of your own personal data just in case something goes wrong during the installation process.
How Do I Fix Target Disk Mode on Mac?
If you find yourself in a situation where you need to use Target Disk Mode on your Mac, there are a few things you can do to troubleshoot the issue. First, make sure that both Macs are properly connected with a FireWire or Thunderbolt cable. If everything is plugged in correctly and the Target Disk Mode still isn’t working, try restarting both Macs.
Sometimes this simple step can fix the problem.
If restarting doesn’t work, the next thing to try is resetting the PRAM on your Mac. This can be done by following these steps:
1. Shut down your Mac.
2. Press and hold the Command + Option + P + R keys simultaneously while pressing the power button to turn on your Mac.
3. Hold these keys until you hear two startup chimes indicating that the PRAM has been reset successfully.
4. After resetting PRAM, try using Target Disk Mode again and see if it works now.
If neither of these solutions works, it’s possible that there’s an issue with one of theMacs’ FireWire or Thunderbolt ports or cables.
How Do I Install Mac Os on Another Mac?
There are a few different ways that you can install Mac OS on another Mac. The first and most common way is to use the “Install macOS” app that is included with every new Mac. This app will allow you to download and install the latest version of macOS onto your computer.
Another way to install macOS is by using a bootable USB drive. This method requires you to have a USB drive that is at least 8 GB in size and that has been formatted for use with a Mac. Once you have created your bootable USB drive, you can then use it to install macOS on your computer.
The last method for installing macOS is by using an ISO file. An ISO file is a disk image that contains all of the data necessary to install macOS on a computer. You can usually find these files online from sites like Apple’s website or from third-party websites.
Once you have downloaded an ISO file, you can then use it to create a bootable USB drive or burn it to a blank DVD/CD.
Can I Install Macos from Usb in Recovery Mode?
It is possible to install macOS from USB in recovery mode. This can be done by using the createinstallmedia command in Terminal. However, it is important to note that this will erase the contents of the USB drive, so it should only be used with a blank drive.
In addition, the process may take some time depending on the speed of your USB drive and computer.
