iTerm2 has more functions, is more customized and has better ease of use than macOS's default terminal. 1. In terms of functions, iTerm2 supports split screen, enhanced search, hotkey windows and mouse interaction, while the terminal only provides basic functions; 2. In terms of appearance, iTerm2 supports preset themes, hyphen fonts and background pictures, while the terminal only provides basic style settings; 3. In terms of integration, iTerm2 supports Python/AppleScript scripts, better Tmux integration and task completion notifications, and the terminal has weak integration capabilities; 4. In terms of performance, iTerm2 renders faster and has better high resolution display, but the terminal is more stable due to the native system support. Therefore, if you use optional terminals for daily use, heavy developers are more suitable for iTerm2

To solve the problem of self-starting application after booting, you must first enter the system settings management startup item. Windows users can disable irrelevant programs through the "Start" tab of Task Manager; macOS users operate in the "Login item" of "Users and Groups". Secondly, pay attention to uninstalling software that disguises as necessary services, such as input method, driver management tools, cloud disk client, etc. Finally, it is recommended to enter the software's own settings to cancel the boot option, such as the related settings of WeChat and Steam, to completely prevent them from automatically restoring and starting up. Regular checking of start items can effectively avoid waste of resources and improve startup speed.

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. Quickly switch desktops can be swiped left and right by Control left and right arrows or the trackpad three/four fingers, and can also automatically jump to the corresponding desktop when the Command Tab switches applications. The method to fix the application window to a specific desktop is to select the window and select the target desktop through the menu bar "AssignTo" to make

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. Best practices include: only when necessary, avoid blindly executing network commands, editing sudoers files with visudo, and considering continuous operations.

To set up the HotCorners function of macOS, first open "System Settings", enter the "Desktop and Screen Saver" interface, click the "HotCorners..." button in the lower right corner, and set operations for the four corners, such as displaying the desktop, starting MissionControl, entering the screen saver, etc. It is recommended to assign common functions to different corners to improve efficiency, such as setting the lower right corner to "Show Desktop" and setting the left and right corners to MissionControl. 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.
