MacBook 12" no longer starts: Error -1005F

Hello everyone.

When I start the Mac normally, I get a flashing folder with a question mark. As far as I have read, this means that the start-up system cannot be found. So I try to start the Mac by holding down the Alt key and selecting the start-up medium. Here, however, I have to establish a WLAN connection. However, no network is displayed there and a manual entry is also unsuccessful (no LAN connection either).

So now I want to open the recovery system by cmd r or cmd alt r. But now I get a globe with the error description -1005F. As far as I have read, this means that the WLAN connection is not suitable for macOS recovery. However, the problem cannot be avoided with other WLAN connections or even with a LAN connection.

I also tried to create a Reboot USB Stick with the latest MacOS but i cannot select it when I start the Mac pressing the alt key.

Any Ideas?

Hello Helios_007,

Thanks for posting in Apple Support Communities!

We understand that you're seeing a folder with a flashing question mark during start up on your Mac. We'd like to help.

Here's what you can do If your Mac starts up to a question mark. Try those steps out first. If you continue to see this error code when trying to start up from macOS Recovery, Use Apple Diagnostics to test your Mac and to help diagnose the issue.

Take care.

Helios_007,

Thanks for providing that follow up information. We would recommend reaching out to Apple Support as a next step if you're unable to boot into macOS recovery and are noticing that it could be possibly hardware related. Here's how to Get Support.

Have a nice day.

Hello and thanks for your Help.

I already tried any of those steps. The only thing that changed is that I now hear the boot sound anytime I start the MacBook. But apart from that anything stayed the same.

Also if I try to run the diagnostics I get the globe with the error message again :/

I currently assume that the usb c connection is faulty. But is it possible that the port can still be used to charge the computer but is no longer capable of data transfer or usb recognition? That is the only thing that seems weird to me about that.

Because when boot my iMac (2nd PC) via alt key all the local networks are displays as well as the boot stick, unlike the MacBook. That is why I think the problem should be on the hardware side of the Macbook.

But since I am no expert, these are only assumptions I made up and could very well be wrong about them.

Hi,

I would try one last thing.

1) PRAM and SMC reset

2) Ask for an Ethernet to USB-C adapter, Ethernet cable directly to the router.

3) Turn on the MB and then press Alt+Cmd+R
