You can cancel a subscription from Apple or a subscription that you purchased with an app from Apple’s App Store. Here’s how to do it on your Mac.
° Open the App Store app.
° Click your name. If you can’t find your name, click Sign In.
° Click Account Settings.
° Scroll to Subscriptions, then click Manage.
° Next to the subscription, click Edit.
° Click Cancel Subscription. If there’s no Cancel or Cancel Subscription button, the subscription is already canceled.
