Installation

To make settings work across all apps in iOS , iPadOS & macOS , you'll need to install configuration profile. This profile would tell operating system to use DoH / DoT. Note: it's not enough to simply set server IPs in System Preferences — you need to install a profile.

Download DoH profile
Download TLS profile
Download unencrypted profile NOT RECOMMENDED
sha256 sha512

iOS / iPadOS: Open the mobileconfig file in GitHub by using Safari (other browsers will just download the file and won't ask for installation), and then click/tap on "Allow" button. The profile should download. Go to System Settings => General => VPN, DNS & Device Management , select downloaded profile and tap the "Install" button.

macOS (official docs) :

1. Download and save the profile. After save, rename it to be in format: NAME.mobileconfig , not NAME.txt, or so

1. Choose Apple menu > System Settings, click Privacy and Security in the sidebar, then click Profiles on the right. (You may need to scroll down.)

You may be asked to supply your password or other information during installation.

1. In the Downloaded section, double-click the profile.

1. Review the profile contents then click Continue, Install or Enroll to install the profile.

If an earlier version of a profile is already installed on your Mac, the settings in the updated version replace the previous ones.
