I guess I dodged a bullet when I bit the bullet. The machine on which I successfully installed the new OS? A late 2013 MacBook Pro. That doesn’t sound like fun, and hopefully something Apple will be addressing soon. There is a support thread on indicating that the Macs being affected are the late 2013 and mid-2014 MacBook Pros, and some have had some success in unplugging the I/O board before attempting to re-install macOS 11. During the installation process, the impacted computers freeze on a black screen, and none of the usual key commands for NVRAM reset or booting into safe mode appear to be working. No chime, no keyboard lights, no fan – nothing. According to MacRumors, the installation of macOS Big Sur is causing problems and bricking their machines. But this time around, I decided to bite the bullet and load up Big Sur on my MacBook Pro. I usually wait a few months before upgrading to the latest and greatest macOS, or at the very least, the first major revision (macOS 11.1 in this case).
