The Private Window feature in Safari is handy, but perhaps not for the reasons you think. It does not really provide any security or hide your browsing activity from your ISP or work IT department.

You may not think it is important to set a Wi-Fi password in your home. But without one, the data being sent from your Mac and other devices may by unencrypted and easy for someone to snoop. You should set a password and also be wary of public Wi-Fi that does not require a password.

Old-fashioned file sharing can still be useful at home or work, but it opens up a security vulnerability if you connect to a public network.

If your Mac is stolen you may be able to track it if you have enabled the Find My Mac feature. This will also let you remotely wipe your Mac in some cases.

A simply battery system can protect your Mac from short power outages and let you gracefully shut down your Mac in the case of longer ones. A UPS can also be used on your Wi-Fi system to prolong your Internet connection in case of a power failure.
