How do you enable “bootable” on MacBook? 12” MacBook (Early 2016) Model: 1534 EMC 2991
I’m trying to use a USB to use a software on a MacBook that won’t boot. I’ve been doing everything from recovery mode.
Everything is fine with the USB it’s journaled, guid, writable, except one thing, and that’s bootable. It says “no” for it. How would I go about enabling this setting?
Is there a command in terminal to help me enable this setting?
Thanks.

Edit: and also for some reason when I hit “option” when I boot, I only see the option to boot into internet recovery mode it wont give me the choice to select my usb. Am I doing something wrong?
Edit #2: so when I try downloading something I get his message that my SSD is full and this could be the reason why it won’t mount. Does anyone know how to free up space on it? Erasing won’t work.
You cant make a drive bootable through terminal. You have made a mistake using the install so the drive is not bootable. Try again but use the installer directly from the app-store and it should work.
