You may not have another app open, but you may have a service running that does this. Either one that starts with the machine, or one that is left over from a program that was previously running.
You can eliminate the latter by rebooting, and seeing if you can get Now running from a clean start, but it won’t fix the former.
You could usefully search the Community for similar reports; some software called Panopto has found to be the culprit in several cases, and other software is mentioned; see if you recognise any of the names mentioned.
A useful tool here is Activity Monitor.
- Open a Finder window and navigate to Applications>Utilities.
- Double-click Activity Monitor.
- In the main window, you will see a list of processes. This is everything running on your Mac right now.
- If you click on a column header, you can order processes according to the CPU cycles, RAM, or other resources they are using.
I’ve sorted mine by Process Name, but there are 440 to go through, so the Search, top right, where you can put in things like ‘screen’, or ‘capture’, may be of help.
One of my colleagues on the Community, @redchiz1 , is much more of a Mac expert than me, so I have included him to see if he can help here any further.
Set a Payment PIN on your account so that no-one but you can buy memberships on it. Check your bank accounts monthly for any other unexpected payments to Now. That way you can at least nip them in the bud, while you and Now figure out whose fault they are.
