Everyone knows a new Mac is pretty secure right out of the box. There are still things and settings you can tweak to make them even more secure.
1 Update macOS:
The first thing you should do is click the apple menu on the top left > choose System Settings… > Click General > click Software Update and make sure you are running the latest system.
2 Keep macOS and Apps Updated:
Now MacOS is updated, regularly check for software updates in System Settings… > Software Update. Keeping your OS and applications updated helps protect against security vulnerabilities. Make sure Install Security Responses and system files is turned on.
3 Enable FileVault:
Turn on FileVault in System Preferences > Security & Privacy. This encrypts your entire disk, making it harder for unauthorized users to access your data. Don’t confuse this with a Firewall. It’s sounds like it would slow your Mac down, but it has very little impact on performance.
4 Use Two-Factor Authentication:
Enable two-factor authentication for your Apple ID. This adds an extra layer of security when logging into your account on any Apple device.
5 Manage Privacy Settings:
Review privacy settings in System Settings… > Security & Privacy > Privacy. Control which apps have access to your location, contacts, and other personal information.
6 Activate the Firewall:
Enable the firewall in System Settings > Security & Privacy > Firewall. This helps protect your Mac from unauthorized access over the network.
7 Be Cautious with Downloads:
Only download software from trusted sources, such as the Mac App Store or official websites. Avoid clicking on suspicious links or emails.
8 Use a Guest Account:
If you share your New Mac, consider setting up a guest account for others to use. This prevents them from accessing your personal files.
9 Turn Off “Automatically Log in as”
Keep this setting turned off, this means the password is needed to access your Mac
10 Back Up Regularly:
Use Time Machine or another backup solution to regularly back up your data. This ensures you can recover your files in case of loss or ransomware.
