On the display of the MacBook, a folder with a question mark - what is it?

Question

macOS

Actually, MV 12 "does not load, but this is what is on the display: This is the

first time I see this, although I raised the systems from the first cat ones. Maybe an SSD?

Answer 1

The disk is finished or the system is somehow screwed up. To service. These 12s are almost impossible to fix manually. If you installed Mojave, then without a service, this is no way at all.

Answer 2

Well, about the kranty disk) it’s too early to talk about this)) the world is alive with more than one poppy and it won’t be difficult to check a live or dead screw
It’s very likely that you need to change the HDD cable. This cable is Apple's 8th wonder of the world. Why a miracle? Because only in the poppy this cable is made in the form of a “downward” The
downhill lies in the fact that it is fragile and over time or when replaced with the same SSD it simply fails) - at the same time, Apple engineers invented a miracle to bend it twice at an angle of 90 hail - such a step)) so that someone who does not know must break the train)
Something like this)

Answer 3

Dear advisers - do you even know what the macbook 12 consists of, to give advice in the "check the loop" format - this is just the height of stupidity. There, the motherboard is the size of a smartphone and everything is soldered to it. Nothing changes from the word at all, what the hell are you going to check loops? If the disk is dead - everything, service and hello.
