How to Start Up a Mac in Internet Recovery Mode

はじめに

If your Mac isn't connected to a storage drive with macOS installed, or your boot drive is corrupted, the computer will flash a question mark folder icon on startup, and then shut down.

Follow this guide to boot your Mac to Internet Recovery mode and access recovery tools like Disk Utility, Time Machine, and the macOS installer.

Internet Recovery is only available on Apple computers made after 2009. If your computer was released in 2010 or 2011, you may need to update to the latest version of macOS and/or perform an EFI and SMC firmware upgrade to enable Internet Recovery.

    • Once a network connection has been established, a progress bar will appear underneath the spinning globe.

    • This process is prone to timing out. If you receive an error, try again using a cable connection to reach the internet rather than WiFi. Depending on your model, you may need an adapter to accomplish this.

Oh, I’m so sorry! I forgot to specify: internet recovery mode is only available on newer Apple computers. I’ve updated the intro now, sorry for the confusion!

So a mid 2009 computer won’t have internet recovery mode?

I bought a Asgard (seems operates from HongKong) 2TB NVME PCIe M.2 SSD that I installed into mackbook pro 15in mid 2015 with sintech adapter for conversion to MacBook AHCI controller. The disk utility does not show this SSD. Later I installed in same way another Sabrent SSD 2TB it worked fine.

What might have gone wrong in the fist SSD. Could that SSD itself faulty or incompatible? any fixes available?

Two main reasons:

- You aren’t pushing deep enough your new ssd drive into the slot. Please reopen your mac, unplug the battery connector and push the new ssd to a fashion position.

- Your are missing the Alt/Option key. Please make the full shorcut: Alt+Shift+R.
