2. Click on “Security & Privacy.”
3. Select the “General” tab.
4. Under “Require password after,” choose the desired time interval for your Mac to automatically lock.
The Power of a Password: Protecting Your Mac from Unauthorized Access
A strong password is the cornerstone of any secure system, and your Mac is no exception. A robust password acts as a barrier against unauthorized access, ensuring that only you can unlock your device.

Advanced Security Measures: Keeping Your Mac Safe from Threats
Beyond basic locking mechanisms, there are several advanced security measures you can implement to enhance your Mac’s protection.
1. Enable FileVault: This feature encrypts your entire hard drive, ensuring that your data is protected even if your Mac falls into the wrong hands.
2. Use a Screen Lock: This feature prevents unauthorized access to your Mac’s screen, even if someone has physical access to your device.
3. Enable Two-Factor Authentication: This adds an extra layer of security by requiring a code from your phone in addition to your password when logging in.
4. Install Antivirus Software: While macOS is generally considered secure, it’s still essential to have antivirus software installed to protect against malware and other threats.
Taking It Further: A Comprehensive Approach to Mac Security
While locking your Mac is a crucial step towards security, it’s only part of a comprehensive approach. Here are some additional tips to enhance your Mac’s protection:
1. Keep Your Software Updated: Regularly update your macOS and applications to ensure you have the latest security patches.
2. Be Cautious of Downloads and Attachments: Only download software from trusted sources and be wary of opening attachments from unknown senders.
3. Use Strong Passwords: Not just for your Mac, but for all your online accounts.
4. Be Aware of Phishing Scams: Don’t click on suspicious links or provide personal information to untrusted websites.
5. Back Up Your Data: Regularly back up your important files to an external drive or cloud storage service.
