What Happened: Laptops that are most commonly affected include late-2013 and mid-2014 models of the 13-inch MacBook Pro, according to The Verge.
The issue reportedly involves a black screen during installation, which is not user-fixable. The issue was first noticed by MacRumors, which made references to Reddit posts of users who were asked by Apple to bring in their machines for repair.
“I have a late 2013 MacBook Pro 13. Tried updating to Big Sur and noticed that after some progress bars the screen turned black,” a user wrote on Reddit. “Screen turns on, but there's no chime, fans don't spin and [I] can't get into recovery nor internet recovery. Tried resetting the NVRAM, SMC, connecting to an external monitor, nothing works.”
Why It Matters: Demand for the latest version of macOS has slowed down the Cupertino, California-based tech giant’s servers, The Verge noted.
Users of Big Sur have also reported issues related to opening third-party applications on their computers due to a security feature called “Gatekeeper,” while others express privacy concerns.
The Tim Cook-led company has laid out the steps it intends to take to fix the glitches affecting macOS over the course of the next year.
Price Action: Apple shares closed nearly 0.9% higher at $120.30 on Monday and fell 0.33% in the after-hours session.
