    When Should You “Ignore Ownership” on an External Drive?

    Under the hood, macOS relies on Unix, which is a multi-user operating system. That’s why a Mac can host multiple users who, as long as they don’t know each other’s passwords, cannot see each other’s files. To maintain each user’s privacy, macOS relies on permissions that specify who can do what with any given file or folder. For the most part, permissions work how they’re supposed to, letting y...

    iOS, iPadOS, and macOS all let you specify whether any given app should show no notifications, temporary banners, or persistent alerts: look in Settings > Notifications and System Settings > Notifications.

    It’s Usually OK to Share Full-Size Images in Email and Messages

    In the early days of the Internet, when most people connected via slow modems, saving bandwidth was a big deal. You could watch images load on Web pages, and you’d have to wait to download a large email attachment before the rest of your email would appear. For most people, in most situations, bandwidth isn’t nearly as big of a deal anymore. The average Internet download speed in the US is near... Read more

    Six Reasons Why You Should Restart Your Mac Periodically

    Long ago, before macOS was as stable as it is today, Mac users restarted their Macs regularly. Back then, Macs couldn’t sleep, either, so it was common for users to shut down at the end of the day and start up the next morning, effectively restarting daily. With modern Macs using the barest trickle of power in sleep and both apps and macOS almost never crashing, many Mac users have gone to t... Read more
