I recently learned this.
Very timely video.
After closing the lid on my MBP and leaving
for several hours, my computer opened up
without needing a login. Care explained this
to me. Now when I leave my computer, I logout
of my user.
DBob: Check System Preferences, Security & Privacy, General. Make sure you gave the "Require Password" option checked and set to "Immediately."
My computer sometimes wakes up during the night (no, it doesn't have an enlarged prostate). Is there a way to check activity over a certain time period? Thanks.
Alan: LOL. Nothing I can think of. Usually that is caused by Bluetooth items (keyboards, mice, headphones, speakers, etc) or USB peripherals. But it could be software (system extensions and such, not really apps). Also check in Energy Saver under "Wake for network access."
I couldn't even find activity monitor. Where is it?
Peter: It is in Applications/Utilities. But use Spotlight, or LaunchPad to find it easily.
