How to Boot Mac from USB Media: After creating a bootable USB drive, the user simply needs to plug the created drive into the open port on the Mac. Here are the steps to boot Mac from the USB flash drive: Power on the system. Press and hold the Option (Alt) key on the keyboard when the computer starts.

I have been trying to reinstall macOS on my MacBook Pro 13 (2015) and for reasons I still don't know, the bootable USB I created was not showing up when I booted into the Startup Manager (by holding the option/alt key).

I tried creating the USB via both diskmarkx and Terminal. But neither was helping me. Then I tried several fixes and this one finally solved the problem. For any of you out there facing the same problem, this might help.

Steps :

1. Reset PRAM of your machine by holding option+command+P+R keys together soon after you press the Power button and hear the startup chime.

2. Hold the keys until the grey screen goes off completely (the machine should be restarting).

3. At 'this' point, insert the Bootable USB Disk you created and press and hold the option key. Smart zipper pro 3 7 0.

4. Hold the option key until you see the Startup Manager.

Hopefully your USB should be listed as one of the bootable disks in the Startup Manager.

This page describes the technique to start Tails from a USB stick on Mac.

1. Troubleshooting Tails not starting at all
2. Troubleshooting Tails not starting after the Boot Loader

1. Shut down the computer while leaving the USB stick plugged in.

   Plug in the other Tails USB stick that you want to install from.

2. Switch on the computer and immediately press-and-hold the Option key (Alt key) until a list of possible startup disks appears.

3. Choose the USB stick and press Enter. The USB stick appears as an external hard disk and might be labeled EFI Boot or Windows like in the following screenshot:

   If the USB stick does not appear in the list of startup disks:

   1. Make sure that you have verified your download of Tails.
   2. Try installing again on the same USB stick.
   3. Try installing on a different USB stick.
   4. Try using the same USB stick to start on a different computer.

   If your computer still does not display the Boot Loader, it might currently be impossible to start Tails on your computer.

4. If your Mac displays the following error:

   Then you have to change the settings of the Startup Security Utility of your Mac to authorize starting from Tails.

   To open Startup Security Utility:

   1. Turn on your Mac, then press and hold Command(⌘)+R immediately after you see the Apple logo. Your Mac starts up from macOS Recovery.

   2. When you see the macOS Utilities window, choose Utilities ▸ Startup Security Utility from the menu bar.

   3. When you are asked to authenticate, click Enter macOS Password, then choose an administrator account and enter its password.

   In the Startup Security Utility: Cad lisp free download.

   • Choose No Security in the Secure Boot section.

   • Choose Allow booting from external media in the External Boot. Apple format apfs.

   To still protect your Mac from starting on untrusted external media, you can set a firmware password, available on macOS Mountain Lion or later. A firmware password prevents users who do not have the password from starting up from any media other than the designated startup disk.

   If you forget your firmware password you will require an in-person service appointment with an Apple Store or Apple Authorized Service Provider.
