This means less throttling and a smoother experience.

Below, we will take you step by step from scratch to master this tool. Whether you are a Mac novice just starting out or an experienced user pursuing ultimate performance, you will find a usage that suits you.

I. Detailed Explanation of the Software’s Core Interface and Workspace

TG Pro’s main interface is intuitive and mainly divided into three core areas: the menu bar icon, the main monitoring window, and the preferences panel. These three areas each have their own roles, covering everything from quick viewing and in-depth analysis to global configuration.

1.1 Menu Bar Icon

• Location and Display: After launch, the TG Pro icon resides in the menu bar at the top right of the screen. The icon itself displays a key temperature (by default, usually the CPU core temperature). This number changes in real time, allowing you to grasp the device status at any time.
• Quick Actions: Clicking the icon pops up a dropdown menu showing the current temperatures of all core sensors (such as CPU, GPU, SSD) and the current speeds (RPM) of all fans. The information is clear at a glance without opening the main window.
• Quick Control: At the bottom of the dropdown menu, you can directly switch the fan control mode (auto/manual), or quickly set the fan to “maximum” speed in manual mode. This is very convenient when you temporarily need strong heat dissipation, such as when exporting videos or playing games.

1.2 Main Monitoring Window

Open by clicking “Open TG Pro” in the menu bar icon or double-clicking the application icon.

• “Overview” Tab: Clearly displays all key information in card form, including:
  • Temperature Sensors: Lists the real-time temperatures of components such as CPU PECI, GPU, SSD, and battery. You can intuitively see which component is “running hot.”
  • Fans: Displays the current speed, minimum/maximum speed, and control status of each fan. This helps determine whether the fans are working properly.
  • Hardware Diagnostics: Displays battery health status, cycle count, and any history of overheating shutdowns. This is an important basis for determining whether the battery needs replacement.
• “Fans” Tab: Provides a detailed fan control panel. Here you can set the control mode for each fan individually and view the speed curve graph. Advanced users can fine-tune the fan response logic through the curve graph.
• “Log” Tab: Records all temperature events, fan speed changes, and system diagnostic information in chronological order, which can be used for tracking and analysis. When the computer experiences intermittent lag or fan noise, the log is the first-hand material for troubleshooting.

1.3 Preferences Panel

Open via the main menu TG Pro > Preferences... or using the shortcut Command + ,.

• General: Set startup options and menu bar display content (such as which temperature to display). You can choose to display CPU, GPU, or hard drive temperature to suit personal preference.
• Notifications: Configure temperature threshold alarms, which can be sent via system notifications or email. For example, when the CPU temperature exceeds 90°C, the system will immediately pop up a reminder.
• Advanced: Set automatic fan control rules (“Auto Boost”), logging options, and other core functions. This is where refined thermal management is achieved.

II. Complete Operation Workflow: From Startup to Monitoring and Management

This section will take you through the complete process from installation and first launch to daily monitoring. Ensure every step is clear and accurate.

2.1 Startup and Initial Check

1. Launch the Software: Find and double-click the “TG Pro” icon in the “Applications” folder. After the software launches, a temperature icon will appear in the menu bar.
2. View Instant Status: Click the menu bar icon to quickly browse all sensor temperatures and fan speeds, confirming there are no abnormal high temperatures (usually CPU/GPU idle temperatures between 40-60°C are normal). If the temperature display is abnormal, such as exceeding 100°C, you can first check whether a large application is running.
3. Open the Main Window: Click “Open TG Pro” in the menu bar dropdown menu, or use the shortcut Command + O to open the main monitoring window for detailed inspection. On the “Overview” page of the main window, you can see more complete hardware diagnostic information.

2.2 Configure Fan Control Mode

This is TG Pro’s core function. You can choose different modes according to your needs. The correct mode selection balances cooling performance and noise control.

1. Switch to the “Fans” Tab.
2. Select Control Mode:
   • Auto (Recommended): Let macOS (or TG Pro’s automatic rules) intelligently control the fans. Select “Auto” in the dropdown menu. This method is suitable for most daily usage scenarios.
   • Manual Control: If you need immediate strong cooling, select “Manual” for each fan, then drag the slider or click the “Maximum” button to pull the speed to the highest. Shortcut: Directly click “Set Fans to Maximum” in the menu bar dropdown menu. Note that manual mode increases noise, so use as needed.

2.3 Set Temperature Alarms and Logging

1. Open Preferences (Command + ,) and go to the “Notifications” tab.
2. Click the “+” button at the bottom left to add a new alarm rule.
3. In the popup window, set:
   • Condition: For example, “Any CPU temperature > 85°C”. You can adjust this threshold according to your computer’s cooling capacity.
   • Action: Check “Show notification” and optionally “Send email”. For servers or work machines that require remote monitoring, email alarms are very practical.
4. In the “Advanced” tab, you can enable “Log to file” for later analysis of detailed CSV logs.

2.4 Daily Monitoring and Quitting

• Daily Monitoring: Mainly through the menu bar icon, there is no need to keep the main window open. Occasionally glancing at the temperature number in the menu bar gives you a clear understanding of the computer’s status.
• Completely Quit: To completely quit the software, click TG Pro > Quit TG Pro in the menu bar, or use the shortcut Command + Q. Note that after quitting, monitoring and fan control will stop. If you want TG Pro to continue running in the background, it is recommended not to quit but to simply close the main window.

III. Advanced Tips for Common Functions

After mastering the basic operations, these advanced tips can help you further unleash TG Pro’s potential and achieve personalized thermal management.

3.1 Create Custom Automatic Fan Curves

This feature allows fan speed to respond more precisely to temperature changes, achieving a balance between silence and cooling. This is one of TG Pro’s most powerful features.

1. Go to Preferences > Advanced.
2. In the “Auto Boost Rules” section, click “Edit Rules…”.
3. Click “+” to add a new rule, for example: If "CPU PECI" temperature > 70°C, then set "Left Fan" to 2200 RPM.
4. You can add multiple rules to form a stepped fan control strategy. For example, 1500 RPM at 60°C, 2200 RPM at 70°C, 3000 RPM at 80°C.

3.2 Interpret Battery Health Diagnostics

In the “Hardware Diagnostics” section of the “Overview” tab in the main window, pay attention to:

• Status: Displays “Normal”, “Replace Soon”, or “Replace Now”. This is the battery health rating provided by Apple’s official API and is trustworthy.
• Maximum Capacity: Below 80% usually indicates the battery has significantly aged. When maximum capacity is below 80%, the Mac may recommend battery service.
• Overheating Shutdowns: Records the historical number of times the Mac has shut down due to overheating, which is an important basis for judging cooling issues. If this number is increasing, it indicates a possible problem with the cooling system.

3.3 Use Logs for Troubleshooting

When the Mac experiences abnormal fan noise or performance degradation:

1. Open the “Log” tab.
2. Check whether there are temperature spikes or drastic changes in fan speed around the time the problem occurred.
3. Combined with the log information, you can determine whether it is high load caused by a specific application (such as video rendering or large games) or a persistent cooling problem. For example, if the log shows the fan speed remains high but the temperature is still high, it may be due to dried thermal paste or dust accumulation in the fans.
