If you click on the Up arrow right below the icon for the USB, the computer will only startup once using this disk. If you press and hold down the Control key while making your selection, it will be saved, and your computer will boot from the USB every time, as long as it is left in the computer.
At this point, you can also use the Mac installation disk to boot your Mac from. As an alternative, you can start your Mac in Recovery Mode. This will allow the system to automatically detect and repair directory issues. Recovery Mode will only allow required kernel extensions to load, preventing login items and startup items to load automatically. It can also help you isolate the issue depending on whether or not the issue goes away in Recovery Mode.
If the issues you have during normal startup don't show up in Recovery Mode, they are most likely fixed. That means you can reboot normally and your system should be back to normal. Step 1 : Start your Mac and hold down the Shift key. You will see the Apple logo on your screen. Step 2 : When you see the login screen, you can release the Shift key and login to your Mac. Terminal is the easiest way to create your bootable USB drive. Just replace the MyVolume portion of the commands below with the name you gave your drive in the Disk Utility step above.
Take note that the commands differ slightly for creating bootable USBs for different versions of macOS. If you are going to create a bootable drive for macOS Monterey, use the command below as it is. Otherwise, replace Monterey with the macOS version name for example Mojave , etc. Copy and paste the command you need above into your Terminal window and press the Return key. After entering your password, confirm you want to erase the USB drive by typing Y followed by Return.
Terminal will now erase and create your bootable USB drive, ready for you to boot from. If you prefer creating a bootable disk using the software method, you can use third-party applications to do so. Diskmaker X was the famous go-to utility for creating bootable disks, but it doesn't support the latest versions of macOS High Sierra onwards.
Once you've downloaded the software, simply open it up. The app should automatically detect the macOS installer in your Downloads folder. Simply select the USB drive that you want to create a bootable disk on from the top volume dropdown list, and click on Create Installer. Now if you find yourself in a sticky situation where your Mac isn't booting, or you want to do a fresh install of macOS, you have a solution. This will come in handy for fixing the "macOS could not be installed" error.
There are two different methods to boot your Mac from a bootable USB, depending on which processor your Mac has. Power on the system, or restart it if it's already on, and immediately press and hold the Option Alt key when it starts booting.
To boot an M1 or Apple silicon Mac using a bootable USB disk, power on the system or restart it if it's already on, and keep the Power button pressed down.
You should now see an option to select your USB drive as a startup disk. If you want to erase your disk first to do a clean install, quit the installer and run Disk Utility from the Recovery menu. You can then format the drive, and then go back to the Recovery menu and install macOS Monterey. Some wireless keyboards may not work at this point. If you're having difficulty, plug in a wired keyboard instead. In some cases, Intel Macs with a T2 chip Intel Macs released after may not allow you to boot a macOS installer from an external drive.
This is due to a setting in the Security Startup Utility that needs to be adjusted.
