Red Square around the Apple Logo when turning ON.
I bought MacBook Pro 2017 Without touch-bar model, when i opened the laptop it was automatically booted. An Apple Logo was on the screen, suddenly there was Red color square around the Apple Logo. Is it a software glitch or hardware issue. Factory default MacOS was :- 10.13.4. Please help me out.
MacBook Pro (13-inch, 2017, 2 TBT3), macOS High Sierra (10.13.4)
