If you click the link that peterlanders included, scroll all the way to the bottom of the page to the section that says “SQ Apps”. To the right, you’ll see SQ Mixpad with a more info button underneath. If you click the more info button underneath, it will take you to a new page. Scroll to the bottom of the page and you will see a link to download the SQ Mixpad app for MacOS. I was confused as well, because it doesn’t show in the App Store on the Mac. Hope this helps 🙂
