Using a Mac computer is not only to know how to perform every single function on the system, but also to know how to maintain and protect it. To secure your devices is to ensure the security of your information. Yet do you really know how to prevent your Mac from being attacked and what precautions do you need to take?
1.Use a non-administrator account to do every day tasks
Every Man user will have his won administrative account, which enables user to manage most of the Mac’s functions, such as installing software, creating new accounts and so on. To prevent being hacked, you can create a non-administrator user in the Accounts pane of System Preferences and use this account for your daily task, like surfing and reading Mail.
2.Apply system updates regularly
It is very important to keep your system updates periodically.
Navigate to Software Update to execute regular updates. For internet-connected systems, you can open the Software Update pane in System Preferences. Note that you need to ensure “Check for Updates” is enabled and set it to “Daily”, so that you won’t miss any updates.
3.Secure Users’Home Folder Permissions
This is to prevent users and guests from reading other users’home folders. What you have to do is to run a command for home folders as bellow:
sudo chmod go-rx /Users/username
4.Disable Automatic Login
Click on the Apple icon on your screen, select System Preferences and then open Account pane. Click on Login Options, set “Automatic Login” to off, and set “Disable login window” as to “Name and Password”
5.Disable unnecessary services
Navigate to /System/Library/LaunchDaemons/ and disable unnecessary services as below using a command with the full path specified, such as sudo launchctl unload -w System/Library/LaunchDaemons/com.apple.blued.plist.
