TG Pro for Mac v2.59 – Control Fan Speed, Monitor Temperature, Activated Version Download

TG Pro is a professional macOS hardware monitoring and fan control tool. It can monitor the temperature of core components such as CPU, GPU, and hard drive in real time, check hardware diagnostic information such as battery health, and allow users to manually or automatically adjust fan speeds to help keep the Mac at optimal operating temperature, thereby improving performance and extending hardware life. This article will introduce its interface, complete operation process, usage tips, and practical cases from multiple dimensions, striving to make it easy for every user to get started and maximize its value.

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

The main interface of TG Pro is intuitive and mainly divided into the following areas:

• Menu bar icon: After launching, TG Pro will display an icon in the menu bar at the top of the screen. Click to quickly view key temperatures (such as CPU) and fan speeds, and directly perform manual fan control.
• Main window (“Overview” tab): This is the core information panel of the software.
  • Temperature sensor list: Clearly lists the current temperature of all available sensors inside the Mac (such as CPU cores, GPU, logic board, hard drive, Thunderbolt ports, etc.).
  • Fan information: Displays the current speed (RPM) and maximum speed of all built-in fans.
  • Hardware diagnostics: Provides key hardware information such as battery health and hard drive SMART status, and will prompt potential issues (such as battery needs service).
• “Fans” tab: Fan control center.
  • Fan control mode selection: Switch between “Auto” (controlled by macOS), “Fixed RPM”, and “Custom rules”.
  • Custom rules list: Allows users to create automatic fan speed-up rules based on specific sensor temperatures.
  • Manual slider: In “Fixed RPM” mode, you can directly drag the slider to set a fixed speed for each fan.
• “Logs” tab: Records all temperature changes, fan speed adjustments, and diagnostic events, which can be filtered by time and exported as CSV files.
• “Preferences” window (opened via menu bar TG Pro > Preferences or shortcut Cmd + ,): Used to configure notifications, startup items, appearance (such as menu bar display content), and software updates.

II. Complete Operation Process: From Launch to Monitoring

Below is a complete operation guide from scratch to ensure you can quickly master the core usage of TG Pro.

1. Launch and Initial Check

Step 1: Find and double-click the TG Pro icon in the “Applications” folder to launch the software.

Step 2: After the first launch, it is recommended to first check the “Overview” tab. This provides a complete snapshot of your Mac’s health. Please pay attention to:

• Temperature readings: Check if any sensor temperature is abnormally high (for example, continuously exceeding 90°C under light load).
• Diagnostic information: Check the “Battery” and “Hard Drive” sections for any warnings or error prompts.

2. Configure Automatic Fan Control Rules (Advanced Cooling)

This is one of the core features of TG Pro, allowing you to create intelligent fan curves. We strongly recommend all users configure this to achieve the best balance between temperature and noise.

Step 1: Click the “Fans” tab at the top of the main window.

Step 2: Ensure the control mode is “Auto (use rules below)”. This is a prerequisite for using custom rules.

Step 3: Click the “+” (plus) button below the rules list to add a new rule.

Step 4: Configure in the pop-up rule settings window:

• If: Select a temperature sensor from the drop-down menu (such as “CPU 1 Core Temperature” or “Highest CPU”).
• Reaches: Set a trigger temperature threshold (for example, 65°C).
• Then: Select the fan to control (such as “All Fans” or a specific fan).
• Increase to: Set the fan speed percentage to increase to when the temperature reaches the threshold (for example, 50%). You can add multiple rules to achieve stepped control where higher temperatures result in higher speeds.

Step 5: Click “OK” to save the rule. Rules will be executed from top to bottom in the list order.

Tip: You can drag the “hamburger menu” icon (three horizontal lines) on the left side of a rule to adjust the priority order of rules. Usually, we place the most critical rules (such as CPU high-temperature protection) at the top.

3. Perform Manual Instant Cooling

When rapid cooling is needed (such as before high-intensity rendering), you can use manual mode. This method is very direct, but remember to switch back to automatic mode.

Step 1: In the “Fans” tab, switch the control mode to “Fixed RPM”.

Step 2: Drag the slider for each fan (or use the “All Fans” master slider) to increase its speed to the desired level (for example, 80%-100%). The fans will respond immediately.

Step 3: After completion, switch the mode back to “Auto”, and fan control will be returned to the system or your set rules.

4. Set Temperature Alert Notifications

TG Pro’s temperature alert function is very practical. It can monitor hardware health in the background while you focus on work. Once configured, it will notify you immediately if the temperature is abnormal.

Step 1: Open Preferences via menu bar TG Pro > Preferences or press Cmd + ,.

Step 2: Click the “Notifications” tab.

Step 3: Check “Enable notifications”.

Step 4: Configure alert conditions, such as “When any sensor temperature exceeds [85] °C”. You can also enable email notifications (requires prior configuration).

5. View Historical Logs and Export Data

The logging function is very useful for analyzing the long-term temperature performance of the Mac, for example, to determine whether dust accumulation has reduced cooling capacity.

Step 1: Click the “Logs” tab in the main window.

Step 2: Use the filters at the top to select the type of events to view (temperature, fan, diagnostics) and the time range.

Step 3: To export data, click the “Export…” button below the log list, choose the save location and format (CSV), and it can be used for further analysis.

III. Advanced Tips for Common Features

In addition to basic operations, mastering the following tips can help you better leverage the potential of TG Pro.

• Menu bar customization: In Preferences > General, you can customize the content displayed in the menu bar icon (such as which sensor’s temperature to display), and even choose to display only the icon or text.
• Fix iMac fan running at full speed: Some iMacs may not correctly control the fan after replacing the hard drive with a third-party one, causing it to run at full speed. In TG Pro’s “Fans” tab, create a rule: “If Hard Drive Temperature reaches 30°C, then All Fans increase to Automatic Control“. This usually “takes back” fan control from incorrect system detection.
• Create independent cooling strategies for GPU: If you often use the GPU for gaming or computation, you can create a separate set of more aggressive speed-up rules for “GPU Chip Temperature” to ensure the graphics card stays cool under high load.
• Launch at login and run in background: In Preferences > General, check “Launch TG Pro at login” and ensure “Show icon in menu bar” is selected. This way, TG Pro will continue monitoring in the background with very low resource usage, without needing to keep the main window open.

IV. Common Problems and Solutions

During use, you may encounter some common problems. Below are detailed troubleshooting and solution ideas.

• Problem: TG Pro shows fan speed as 0 RPM, but my Mac clearly has fans.

  Solution: This usually occurs on certain Mac models that do not support software reading of fan status, or the fan hardware itself is faulty. TG Pro version 2.59 provides clearer error prompts for such situations. Please confirm that your Mac model is in the official support list. If the model is supported but still shows 0, it may be a system permission issue. Try restarting the software or rebooting the Mac.

• Problem: Custom fan rules are set, but the fan does not seem to speed up as expected.

  Solution: Please troubleshoot as follows:

  1. Confirm that the fan control mode is set to “Auto (use rules below)”.
  2. Check whether the rule conditions have been triggered. Observe whether the temperature of the corresponding sensor in the “Overview” tab has reached the rule threshold.
  3. Check the rule order. Rules above are executed first and may affect rules below.
  4. Try creating a simpler, more extreme rule (such as increasing to 100% when the temperature reaches 40°C) for testing to rule out rule setting errors.
• Problem: The menu bar icon does not display or displays abnormally.

  Solution:

  1. Go to System Preferences > Dock & Menu Bar, find TG Pro in the left list, and ensure its switch is turned on.
  2. In TG Pro’s Preferences > General, uncheck and then re-check “Show icon in menu bar”.
  3. If the icon displays abnormally in dark mode (such as text being illegible), please update to the latest version of TG Pro (2.59 has fixed this issue).
• Problem: Battery health shows “Service Recommended”. What should I do?

  Solution: TG Pro reads diagnostic data from the macOS system itself. If it shows “Service Recommended”, it indicates that your Mac battery can no longer hold an effective charge. It is recommended to contact Apple official or an authorized service provider as soon as possible to confirm the battery status and replace it. Continuing to use it may pose risks such as battery swelling or inability to use without power.

• Problem: After manually adjusting the fan, the noise becomes very loud. How to quickly restore?

  Solution: The simplest way is to right-click the menu bar icon and select “Auto” mode. Or, open the main window and go to the “Fans” tab, and switch the control mode back to
