Caffeine- don’t let your Mac dim the display!!!
I have my MacBook up and running 24/7. Usually, when I am away from it I turn off the display, but I am not closing the lid. I also enabled automatic display dimming when computer is not used for 2 minutes. I know it is a short time, but those settings work great for me. Unfortunatelly sometimes when I read for example a long artice auto-dimming display is a bit inconvinient. So I tried to solve my problem in other way than constantly changing settings.
And then I found a small app called Caffeine. It prevents your Mac from dimming display. It is really useful, when you watch youtube or megavideo. It sits in menubar. You can accitwate it by clicking on the icon.
