The plan only costs $1 a month. Apple can almost certainly eat that cost, and anyone who cannot complete their monthly exercise challenge because of illness or injury can probably still afford the $1 to keep the plan going.

The monthly challenge in the Fitness app is tailored to each user based on their exercise habits, right?

Long story short--I don't want to connect my mac to my iCloud account, but every time I login to my laptop, I get three popups in a row that say "This Mac Can't connect to iCloud because of a problem with [my email] ...".

I can't find a setting that allows me to disable this, and online searches have been fruitless.
