If like myself you often find yourself working late into the night on your Mac you can find your eyes starting to hurt. The good news is there is a way to make the screen less harsh on the eyes. You can find Night Shift in:
Apple menu () > System Preferences, then click Displays. If automatic brightness is enabled on your Mac the screen will also be dimmer if the ambient light is not as strong which can make your eyes even more strained.
Apple describes Night Shift as:
“Night Shift adjusts the color of your display after sunset. Many studies show that exposure to bright-blue light in the evening can affect your circadian rhythms and make it harder to fall asleep. After sunset, Night Shift will shift your display colors to the warmer end of the spectrum, making the display easier on your eyes. In the morning, your display returns to its regular settings.”
Already own an iPhone or iPad? you may have already come across this feature, basically Night Shift changes the color output toward the red side of the color spectrum. This reduces the harshness from the blue light coming from the screen which is supposed to disrupt sleep patterns.
Night Shift can be switched on at any time of day or you can use a timer if unlike me you have a fairly steady schedule!
To quickly turn Night Shift on manually which is how I use it open the notification centre:
Night Shift isn’t available for all Mac models or external displays the system requirements are as follows, so if you cannot find it that will be the reason why:

It really depends on your company's needs. For example, many companies need to hire 1099 contractors and in such a case they come with their own devices but not the correct security settings or enforcements. Remember BYOD is a security construct. The idea here is that you should be securing the company's sensitive data in all forms. This may involve implementing policies for contractor-owned devices, ensuring that all devices accessing company data meet minimum security standards, and regularly reviewing and updating these standards to stay ahead of emerging threats.

Get more out of scripting than you may expect
Expect is an extension to the Tcl scripting language written by Don Libes. The program automates interactions with programs that expose a text terminal interface. Expect, originally written in 1990 for the Unix platform, has since become available for Microsoft Windows and other systems. Its functionality allows users to interact with these programs through scripted commands, eliminating the need for manual input.
Cybersecurity is more than having the right tools
Processes, cybersecurity is 99% documentation, writing, that's what it is. If you don't enjoy writing policies and procedures, or enforcing them, be aware that this may lead to conflicts with your coworkers.
