Creating a bootable USB flash drive

How to create a bootable installer for MacOS – https://support.apple.com/sl-si/HT201372

You can use an external drive or additional volume as a startup disk to install the Mac operating system.

These additional steps are primarily for system administrators and others familiar with the command line. You don’t need a bootable installer to update macOS or reinstall macOS , but it can be useful if you want to install on multiple computers without downloading the installer each time.

If the program does not start

Gatekeeper function
By default, macOS should allow software to be installed not only from the App Store and from established developers, but also from third-party sources. If this is not done, an error will appear.

Previously, to do this, it was enough to simply open  System Preferences , go to  Security and Protection , where there was the necessary item in the block ”  Allow the use of programs downloaded from “. Now it is gone.

This feature was not simply removed from macOS, but the menu item was simply hidden.

How to Enable Installing Apps from All Sources on macOS

Gatekeeper technology prevents you from installing an application from a third-party source. Its essence is to prevent you from accidentally installing malicious software. But we are experienced users, so we can afford to disable Gatekeeper.

It’s easy to do. Open Terminal and copy this command there:

Code:sudo spctl --master-disable

Press Enter to execute it, then enter your password.
That’s it, installation of programs from any source is now active again.

Now, when you launch an application from an unknown source, macOS will simply ask you if you are sure that it should be launched.

Or another way – hold down the CTRL key and move the mouse over the application again
– and right-click (from you) – open
– then a window will open and select – open – allow.
