Hello I'm new to mac. When I open activity monitor from the dock, it opens fine. Then when I minimize it, it goes back to the dock. However, when i click on the activity monitor icon again to open it, nothing shows up? How do I get it to reopen once I minimize it? edit: when i right click the activity monitor icon, I see a black diamond next to "Activity Monitor (All processes) instead of a check mark? Is this the problem?
