Mac fans are usually due to the system's efforts to dissipate heat. Common reasons include dust accumulation, high CPU usage in the background process, poor air circulation, and software or SMC problems. First, dust accumulation can hinder airflow, and cleaning with compressed air can be improved; second, background processes such as multi-tag browsers may occupy high CPU, which can be alleviated by turning off high occupancy programs through the activity monitor; third, make sure that the Mac is placed in a well-ventilated place to avoid soft surfaces and tight spaces; finally, try resetting the SMC and updating the software to solve potential problems. If the above method is invalid, it is recommended to contact the official support to check hardware problems. Regular maintenance and attention to the use environment can help reduce fan noise and extend equipment life.

Using macOS's multi-desktop capabilities (Spaces) can significantly improve work efficiency. To create a desktop, you can enter MissionControl through the Control arrow and click the " " button. You can add up to a dozen; to delete a desktop, you also need to enter MissionControl and click "x" in the upper left corner of the desktop, but the Space corresponding to the full-screen application can only be merged by exiting the full-screen.

sudo stands for "substituteuserdo" or "superuserdo", allowing users to run commands with permissions of other users (usually root). Its core uses include: 1. Perform system-level operations such as installing software or editing system files; 2. Accessing protected directories or logs; 3. Manage services such as restarting nginx; 4. Modify global settings such as /etc/hosts. When using it, the system will check the /etc/sudoers configuration and verify the user password, provide temporary permissions instead of continuously logging in as root, ensuring security.

Run sudokillall-HUPmDNSResponder to refresh the DNS cache to make the modification take effect; 5. It is recommended to back up the original file before modification to avoid format errors affecting network access. Pay attention to spelling and grammar when operating to ensure that every step is accurate.

When using it, be careful to avoid excessive settings to prevent accidental touch, and be careful that full-screen applications may affect the function's effectiveness, and ensure that the screen saver is connected with password lock to ensure safety.
