For *macOS 10.15* and later installers are provided for x86_64 (Intel)
systems and for ARM64 (Apple silicon) systems. Download the correct
package for your system from the {downloads}, double-click on the file
name, and follow the on-screen prompts in the Installer
app. Double-click and consult the `ReadMe` file for important
installation notes.

If you have already installed a previous version, you can retain it by
changing its name in the *Applications* folder (such as from _WSJT-X_ to
_WSJT-X_2.7.0_).  You can then proceed to the installation phase.

Take note also of the following:

* Use the Mac's *Audio MIDI Setup* utility to configure your sound
card for 48000 Hz, two-channel, 16-bit format.

NOTE: If you are using macOS with an external audio device and find
that Tx audio spontaneously switches to the motherboard sound device
after a few transmissions, try setting the sample rate to 44100 Hz
rather than the otherwise recommended 48000 Hz.

* Use *System Preferences* to select an external time source to keep
your system clock synchronized to UTC.

* To uninstall simply drag the _WSJT-X_ application from *Applications*
to the *Trash Can*.
