Hello good afternoon I wanted to know what happens if I disconnect the SSD from my macbook pro and connect without the SSD. Thanks in advance.

A drive is required! While you could take out your internal drive you would need an external drive which has the OS to have the system work. All you’ll get is a blinking question mark in a folder icon on your screen as the system is looking for the system files which it can’t find with no drive present.

Yes you can boot iT wil power on but without a USB or something iT wil just let you know iT cant boot.
