How to Access Hidden Mac Settings

macOS gives you plenty of options for customisation and setting things up just the way you want them. However, if you love tinkering with your computers, chances are Mac’s built-in settings are not enough for you. Fortunately, there are a lot of hidden settings in macOS Big Sur that you can play around with. So, if you’re looking to completely customise your Mac experience, here is how to access hidden Mac settings easily.

Access Hidden Mac Settings

There are a couple of ways you can access hidden settings on a Mac. You can obviously use the Terminal; something we will discuss in a later section. Or, you can go ahead and use apps that let you change these settings without having to use the Terminal at all.

I’ll be discussing both methods in this article so you can choose whichever one you like more. You can use the table of contents below to skip over to the method you want to try.

1. Use Hidden Mac Settings with TinkerTool

First we will discuss the easy way change secret settings in Mac. For this, we will use an app called TinkerTool (download). This is a free app, so you don’t need to worry about paying to start editing your Mac’s settings.

Once you have TinkerTool installed, just launch it from the Launchpad or by searching for it in Spotlight (or a Spotlight alternative like Alfred). You will notice a bunch of categories on top, such as Finder, Applications, Fonts, and more.

Within each of these categories you’ll find category-specific settings that you can change. For example, in the Finder tab, you can show hidden files, show path in title, and even add a quit option to Finder.

You can also use the Dock category to customise your Dock completely. As you can see, this offers way more options than what is offered by System Preferences on a Mac. You can even add spacer tiles to your Dock if you want a more customised look.

What I really like is the General tab. Here, I can easily change Mac screenshot formats to anything from the default PNG, to JPG, and even PSD files. You can also disable the screenshot preview, disable shadows, and more.

As you can see, TinkerTool gives you access to a lot of hidden settings in macOS, so you can control your Mac’s settings in a much better way. Most of the changes here will require you to restart the Finder, Dock, etc. However, TinkerTool gives buttons to quickly do those things, such as the button to ‘Relaunch Dock’.

2. Restore Hidden Mac Settings with TinkerTool

If you’re like me, you probably went crazy and changed every single setting you could. While that’s fine, if you have changed a load of stuff that you actually don’t want changed, you can easily restore the settings with TinkerTool as well.

Simply click on the ‘Reset’ tab and click on ‘Reset to pre-TinkerTool state’. You can also click on ‘Reset to defaults’ if you want to do that.

3. Use Terminal to Change Hidden Settings in macOS

While TinkerTool is a really easy way to alter hidden settings on your Mac, all of those settings can also be changed using Terminal commands. Obviously that requires you to know the commands to use, which can be a pain to find.

Still, you will be able to find these commands with a quick search online, and once you have them, you can easily use them in Terminal. I will show you the command to show and hide hidden files on the Desktop using Terminal in this example.

  • Open the Terminal.
  • Type the following command
defaults write com.apple.finder AppleShowAllFiles -boolean true

  • Press the enter/return key.
  • Now type the following command
killall Finder

relaunch finder with terminal

  • This will relaunch the Finder and you will be able to see hidden files on your Mac.

Note: By the way, you can use the command “defaults write com.apple.finder AppleShowAllFiles -boolean false” to hide hidden files as well.

Basically, all the settings that TinkerTool gives you access to can be used via the Terminal as well. All you need to do is search for the command required, and just run it in the Terminal app.
