(As a homage to the Mac chime, by the way, we included the sound at the opening of our latest Happy Hour podcast episode discussing Apple’s October Mac event.I have a Dell U3818DW monitor that I'm using with a new Macbook Pro 16" 2019.

Current MacBooks wake when the lid is opened if they are sleeping but the new machines go one step further. A lesser-known feature about the new MacBook Pros is that the late-2016 laptops actually turn themselves on when you open the lid. The removal of the Mac chime was first noted by.
However, there seems to be a good reason for this change … The new MacBooks end this tradition as the chime has been removed completely and the machines will make no noise at all on boot, unless there is a fault. This is the distinctive noise heard at startup when the Mac passes the initial POST checks Apple has used the same F-sharp chord sound in its computers since 1998. It has been discovered that along with physical function keys, glowing Apple logo and ‘old style’ USB ports, the new MacBook Pros lack the iconic Mac chime when booting up. There’s also a flag to disable the auto-boot behavior.
