My Macs all run 24/7. I restart to do upgrades, but even then I never shut them down.
What is the status of your machine when it is unattended?
I leave the computer on but, when unattended, it is logged out and in sleep mode with a password required to log in again. It awakes from sleep instantly and the time from entering the password until fully booted is only 5 or 6 seconds.
I assume that it is wiser from a security point of view to have an unattended machine logged out and asleep….especially when the unattended periods are usually quite lengthy. Is my security assumption correct?
