Click DOWNLOAD CONFIGS to save configs.zip, then install WireGuard from the App Store, then open it. On the main WireGuard screen, click the "Import tunnel(s) from file" button. Navigate to the Downloads folder, then the configs folder (MacOS automatically unzips .zip files). If you hold click the first file, then hold down the shift button, then click the last file, you can select all the configs at once.
