简介

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 to enable Internet Recovery.

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!

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?

Hi there

I recently replaced the HDD in my iMac 2019, 27” Retina 5K with a OWC 1TB SSD which I formatted before installation. After installing the SSD drive my iMac won’t boot up. I’ve tried everything but to no avail. When I turn the power button on nothing happens unless I continuously hold it and then only the fan comes on. Do you have any ideas what could be the problem?
