UPDATE: April 28, 2021<\/strong>
With the release of macOS 11.3 yesterday, Apple has now fixed the bug that prevented the SoftRAID driver from loading on M1 Macs. After updating to this new macOS release, the SoftRAID version 6 driver will load correctly, and you will be able to access your SoftRAID volumes.<\/p>\n\n\n\n

\"Apple<\/figure><\/div>\n\n\n\n

Last week we alerted you to a critical issue with macOS Big Sur 11.2<\/a> which makes SoftRAID volumes inaccessible on M1 Macs. We warned you not to update your M1 Macs until Apple released a fix for this problem and recommended that if you already had updated and needed to revert to macOS 11.1, the best route was to restore<\/strong> your most recent Time Machine backup.<\/p>\n\n\n\n

If you do not have a Time Machine backup, I recommend using an Intel Mac<\/strong> with your SoftRAID volumes until Apple fixes the problem. If this is not an option for you, my final suggestion is to perform a factory reset<\/strong> on your M1 Mac.<\/p>\n\n\n\n

There are many other situations where you might have to perform a factory reset on an M1 Mac. During our 6+ months of testing, we have had to perform this factory reset four times (and we only have five of the M1 Macs). The problems we have fixed this way include things like M1 Macs no longer booting and M1 Macs losing all network access.<\/p>\n\n\n\n

Performing a factory reset is truly the last recourse<\/strong><\/em>, but it is what I recommend when there is no other option.<\/p>\n\n\n\n

Resetting Your M1 Mac Using DFU Mode<\/h2>\n\n\n\n

Important<\/strong>: Resetting your M1 Mac using DFU<\/strong> (Device Firmware Update) will delete ALL your files on ALL internal volumes on your Mac. This is a real, true, factory reset. We recommend you perform a full backup and disconnect all external storage before<\/em> performing the DFU restore.<\/p>\n\n\n\n

You will need a second Mac to perform the factory reset operation. This second Mac, which I will call the Rescue Mac, can be any Thunderbolt 3 or USB-C equipped Mac running Big Sur.<\/p>\n\n\n\n

  1. Download<\/strong> the IPSW firmware file for macOS version 11.1 from Apple’s CDN<\/a> onto the Rescue Mac. <\/li>
  2. On your Rescue Mac, go to the App Store and download \uf8ff Configurator 2<\/a>.<\/strong><\/li>
  3. Make sure your M1 is shutdown<\/strong>. If it is a Mac mini, unplug it!!<\/em>! (The Mac mini must be disconnected from power for at least 10 seconds)<\/em><\/li>
  4. Connect<\/strong> your Rescue Mac to the M1 Mac.

    Note \u2013 you must use<\/strong> the following Thunderbolt port on your M1 Mac or the factory reset won’t work:
