No, this is not a post about controlled substances – even though it is Friday!
In the past, I have recommended some useful apps to improve your presenter game, including a great little tool called Caffeine. Unfortunately the upgrade to macOS Mojave seems to have finally killed off Caffeine, which is fair enough really since it has not been updated in some years.
Luckily, there is a fantastic alternative called Amphetamine, which sticks to Caffeine’s attractive pricing of "free". It does the same job that Caffeine did, sitting quietly in the menu bar until you need to prevent your display from sleeping – perhaps because it is connected to an external projector and you are trying to show something other than your cool screensaver.
On top of that, though, Amphetamine offers a ton of configuration options. My favourite is that you can create triggers which will automatically prevent your Mac from sleeping in certain conditions. I created a trigger so that my Mac will automatically stay awake when I connect my presentation remote, for instance.
If you don’t want a pill icon in your menu bar, you can also change it to something else, including a version of Caffeine’s classic coffee cup.
Do check out Amphetamine and let me know how you get on.
