Do you know that you can increase or decrease the volume and brightness by adjusting the precision to the maximum? Well you can. And it is that in macOS we have the option to raise or lower both the volume of the speakers and the brightness of the screen in a much more precise way.
The function has always existed but few know about it. In this case, if you are one of those who did not know it, now you can share it with your friends and family since it is really useful in some situations, especially the subject of adjusting the volume of the speakers.
We have been using it for a long time and the truth is that it works perfectly for certain occasions when you cannot adjust the volume of a video, song or similar to your liking. It is always possible to make this type of adjustment, no matter what operating system you have since works on newer ones like macOS Catalina and older ones.
In this case we have to press the keys Shift + Alt + volume button or Shift + Alt + brightness button. This is the combination and with it it is difficult for you not to find the right volume point so as not to disturb and listen to the movie or music in perfect conditions or the level of brightness that you prefer. Another of those simple tricks or rather small tutorials that we have already seen in soy de Mac It's been a while and the best thing we can do is refresh users' memories so they can put it into practice since it is great for many situations.
