Depending on what model MacBook Pro you have and which hard drive, this cord could be USB, Thunderbolt, or Firewire. When you plug the hard drive into your computer, a popup box should appear that will ask you if you’d like to backup your computer using Apple’s built-in backup program, Time Machine. Step 3: Select the unmounted MacBook Pro SSD from the left-hand panel. Step 4: Click First Aid on the top of the window and wait while it verifying and repairing errors. Fix 2: Reformat and reinstall to fix MacBook Pro SSD not mounted/booting. If the MacBook Pro SSD has serious logical errors, Disk Utility cannot repair the disk.
These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.
Download macOS
Find the appropriate download link in the upgrade instructions for each macOS version:
macOS Catalina, macOS Mojave, ormacOS High Sierra
Installers for each of these macOS versions download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation. Important: To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.

OS X El Capitan
El Capitan downloads as a disk image. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal
- Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
- Open Terminal, which is in the Utilities folder of your Applications folder.
- Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace
MyVolume
in these commands with the name of your volume.
Catalina:*
Mojave:*
High Sierra:*
El Capitan: - Press Return after typing the command.
- When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
- When prompted, type
Y
to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created. - When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.
* If your Mac is using macOS Sierra or earlier, include the
--applicationpath
argument, similar to the way this argument is used in the command for El Capitan.Use the bootable installer
After creating the bootable installer, follow these steps to use it:
- Plug the bootable installer into a compatible Mac.
- Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it. - Choose your language, if prompted.
- A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

2020 MacBook Pro boot from USB
Starting in 2018 the Macbook Pro includes a secure boot chip that prevents your Macbook from booting windows, linux, BSD, gentoo, Fedora, Atlas Supervisor, other Mac O/S/s on a usb, etc.
Macbook Pro No Usb Drivers
You CAN boot a 2018 2019 or 2020 Macbook Pro from USB!
But it does take a few steps to get there.
Macbook Pro Not Reading Usb
Step One
Boot into Recovery Mode
To access Recovery Mode, turn off your Macbook, turn it on and hold the Command (⌘) and R keys. Keep holding them through the chime sound until you see the Recovery Screen below…
Yaaay! You entered a secret level with hidden powers!
Step 2
Click on Utlities (on the menu bar at the top of the screen, don’t click on Disk Utlities in the middle of the screen)
Approve with apple watch catalina. Select ‘Startup Security Utility’ and you’ll get this screen…
Change the settings for both to the same as the image above.
Secure Boot to No Security
External Boot to Allow booting from external media
Exit out, shut down the laptop.
Step 3
Plug in your bootable USB device and boot up your 2018 2019 Macbook Pro from USB, hold the Command (⌘) key and you’ll see the startup disk screen, select the USB and boot it up.
Caveats, notes and disclaimers.

- You need an uefi bootable image. (we’re uncertain of other workarounds for grub at this time)
- You may not have any access to the internal drive. Not sure if it is a linux driver issue or some sort of on chip security, but so far, no access.
- Leaving ‘external boot allowed’ is a risk that if stolen, someone might be able to access the internal drive.
- The law of unintended consequences. Apple rarely supports playing around with bootable O/Ss, you could brick an extremely expensive device.
- Apple does have further detail on the T2 security chip and how to use it. Read more before playing around too much in there.
The better option
No Usb On Macbook
If you are looking for a great laptop to run NinjaStik we recommend getting an IBM Lenovo T430i for ~$140 and using it. The T430i is one of the best value for $ deals to run a daily use linux based personal laptop. It’s ugly but it is a solid machine. Macbook with old keyboard.
Macbook Pro No Usb Ports
Using a $140 laptop for linux and not risking your $5000 Macbook Pro is our recommendation.
