Yes, if you have regular Monthly or Annual subscription plan, you are free to use Setapp on two Macs simultaneously. Just install it on your second Mac and log into your account. Note that Educational plan provides a subscription for one Mac only.
To move your subscription from one Mac to another, do any of the following:
- Open Setapp's Menu on your Mac and sign out of the current account. Now, sign in on another computer using your credentials; or
- Open your online Setapp account and go to the 'My devices' tab. Find a device you want to disconnect from Setapp and click 'Deactivate.' Log into Setapp on another Mac.
