How to Tighten MacBook Security: Privacy Settings Worth Checking
Tech site Engadget recommends reviewing the privacy and security settings on Apple MacBook laptops, starting with the lock screen, location services and firewall. The advice also covers what data is shared with Apple.
Owners of Apple's MacBook laptops should review their system privacy settings, tech site Engadget advises. Although Apple has built its brand largely on privacy and security, documents, passwords and other personal data stored on the computer can still be at risk, for example when connecting to an unsecured public Wi-Fi network. The list is not exhaustive, but it offers a starting point for people with a new computer and for those who haven't checked their settings in a while.
Basic protection
The first step is a strong passcode and Touch ID, Apple's fingerprint recognition. A pet's name or a birthday is not recommended. Under System Settings > Lock Screen, users can require a password when the laptop wakes from sleep or a screensaver, and set how long it must be asleep before the password is requested.
Location Services is found under Privacy & Security. It can be turned off entirely, or access can be granted or revoked app by app, since not every app needs to know where the user is. The same section lets users choose which apps may use the camera and microphone.
Under Settings > Wi-Fi, it is worth stopping the Mac from automatically joining unsecured networks, which can expose it to malware or data interception. One option sends a notification asking for permission before connecting. The Firewall, which blocks unwanted connections from other networks or the internet, is off by default; it can be switched on under System Settings > Network > Firewall.
What Apple knows about you
Apple, like other companies, collects data to serve personalized ads, for example in the App Store and Apple News. Under Privacy & Security > Apple Advertising, users can see what the company knows about them and turn off personalized ads. Apple says it does not track users across websites or third-party apps. Switching it off limits how relevant ads are, but not how many appear.
Analytics data, which Apple says is collected anonymously, helps improve its products and can include system crashes, hardware, software and app usage. With permission, some of it may be shared with third-party developers. The data is deleted after a month. Experts cited by Consumer Reports were split on how risky sharing it is. Those who prefer to avoid it can turn off several options under Privacy & Security > Analytics Improvements, including Improve Siri & Dictation and Share with App Developers.
