So lets gather a few pieces of information from that terminal command we ran. We’ll need to fix your GPT partition table in order for your Mac to recognize your macOS partition so we can boot into it.

Your data exists but your Macbook doesn’t really recognize that partition as valid. The good news is that you won’t!

You fire up Terminal in Recovery mode and runĪnd you see this freaking oddity!

Well your mac boots into Internet Recovery and it doesn’t even recognize your internal drive. Now if you are slightly technologically inclined, you must have said to yourself, lets just boot into Internet Recovery right? Just Command (⌘) and R into it, reinstall the OS over your existing installation and voila! In fact it mocks you by saying you need to load a kernel first. Oh boy! You frantically type in words like “boot” or “mac” but it doesn’t really recognize any of those commands. You move on, you forget about that you even did this but the next time you reboot your Macbook, it boots to this screen!
