Apps are opening automatically on MacBook Pro running macOS Sequoia
I'm running macOS Sequoia version 15.6 on a MBP and I encountered an instance of apps opening by themselves. I unlocked my computer this morning to find the activity monitor as well as my iCloud notes open. I was just using the computer the night before and I'm absolutely positive I didn't have either of these apps open. I'm very new to macOS and apple products in general, so I haven't even started to use iCloud yet.
My immediate concern, however unlikely, is that this indicates the presence of Malware. Has anyone experienced an issue like this and do you think it's cause for concern?
