TG Pro for Mac v2.56 Control Fan Speed Monitor Temperature Activated Version Download

TG Pro is a professional Mac hardware monitoring and fan control tool. It can deeply read various sensor data inside the Mac, monitor the temperature and operating status of core components such as CPU, GPU, and hard drive in real time, and provide manual or automatic fan control strategies to help users effectively manage Mac heat dissipation and health, extending device lifespan. This guide will detail its core functions and complete operation process.

I. Core Interface and Workspace Detailed Explanation

TG Pro’s main interface is designed simply and efficiently, with all key information at a glance. Many first-time users report that its layout logic is very similar to macOS System Preferences, with almost no learning curve. We will now break down the specific functions of each area one by one, so you can master all operations within 5 minutes.

1.1 Main Window

After launching TG Pro, the main window opens by default, mainly divided into three areas:

• Sensor List Area (Left): Clearly lists all detected hardware sensors in a tree structure, typically including:
  • CPU: Temperature of each processor core.
  • GPU: Graphics processor temperature.
  • Logic Board: Logic board temperature.
  • Drives: SSD/HDD temperature.
  • Fans: Current speed (RPM) of all fans.
  • Diagnostics: Hardware diagnostic information such as battery health, S.M.A.R.T. status, etc.
• Data Chart Area (Upper Right): Displays historical data of the selected sensor in real-time line chart form, intuitively showing temperature or speed trends. This chart supports mouse hover to view specific values, which is very helpful for analyzing heat dissipation performance under long-term load. For example, you can observe the fluctuation of GPU temperature curve after running Cyberpunk 2077 for 30 minutes.
• Detailed Information and Operation Area (Lower Right): Displays the current value, min/max values, status of the selected sensor, and provides fan control sliders and mode toggle buttons.

1.2 Menu Bar Icon

After launching, TG Pro displays an icon in the top menu bar. Clicking this icon allows you to quickly view key temperature overviews (such as maximum CPU/GPU temperature) and fan speeds, and directly perform quick actions like “Boost” and “Max Fan Speed” without opening the main window. This design is very thoughtful, because most of the time we don’t need to stare at the main interface; the real-time display in the menu bar is sufficient. You can also customize the temperature sensor types displayed in the menu bar in Preferences, so the data you care about most is always visible.

1.3 Preferences

Open via menu bar TG Pro > Preferences... or use shortcut Command + ,. Contains multiple tabs:

• General: Set startup, appearance, units, and other general options.
• Fans (only for Macs with fans): The core area for configuring automatic fan control rules.
• Notifications: Set system notifications or email alerts for events such as high temperature and fan failure.
• Logging: Enable and configure data logging for exporting CSV files for in-depth analysis.

II. Complete Operation Process: From Monitoring to Active Cooling

2.1 Startup and Basic Monitoring

1. Launch TG Pro: Find and click the “TG Pro” icon in the Applications folder or Launchpad. After launching, the main window will automatically open and immediately start reading and displaying all sensor data.
2. View Temperature and Status: Select any item in the left sensor list (such as “CPU Die”), and the right side will display its current temperature, chart, and status. Green values usually indicate normal, while yellow or red may indicate high temperature.
3. Check Battery Health: Expand “Diagnostics” and view “Battery” information. The “Condition” field shows battery health status (such as “Normal”).

2.2 Manual Fan Control (Instant Cooling)

When Mac temperature is too high and rapid cooling is needed, manual mode can be used.

1. In the left sensor list of the main window, click the specific fan name under “Fans” (such as “Left Fan”).
2. In the “Control” section of the right detailed information area, switch the mode from “Auto” to “Manual”.
3. Drag the slider below to the desired speed (RPM), or directly click the “Max” button to immediately increase the fan to maximum speed.
4. To restore system automatic control, simply switch the mode back to “Auto”.

Shortcut Tip: You can perform “Max Fan Speed” operations faster through the menu bar icon. Additionally, if you find the fan noise too loud after manual setting, you can gradually lower the speed to find a balance between performance and noise. This is particularly practical for users who need to edit videos in a quiet environment.

2.3 Configure Automatic Fan Control Rules (Advanced Cooling)

For smarter and continuous heat dissipation management, you can create automatic boost rules.

1. Open Preferences (Command + ,) and go to the Fans tab.
2. Ensure the “Enable custom fan control” option is checked.
3. In the “Rules” area below, click the “+” button to add a new rule.
4. Configure rule parameters:
   • If: Select the trigger condition sensor, such as “CPU Proximity” or “Max CPU”.
   • Reaches: Set the trigger temperature threshold, such as 70°C.
   • Then: Select the fan to control (such as “All Fans”) and its target speed or boost mode (such as “Boost”).
5. You can add multiple rules, and TG Pro will execute the highest speed setting among all matching rules.
6. After configuration, close the Preferences window and the rules will take effect immediately.

2.4 Set Notifications and Logging

1. Notification Settings: In Preferences > Notifications, you can enable macOS Notification Center alerts or configure email alerts for events such as “High Temperature” and “Fan Failure”.
2. Logging: In Preferences > Logging, check “Enable Logging”. You can set the logging interval, retention period, and specify the save location for CSV log files for later analysis of temperature trends.

2.5 Quit and Background Running

Directly closing the TG Pro main window does not quit the software; it runs in the background with the menu bar icon remaining visible. To completely quit TG Pro, right-click the menu bar icon and select “Quit TG Pro”, or use the shortcut Command + Q. If you want TG Pro to launch automatically at login, you can enable the “Launch at Login” option in Preferences. This ensures that every time you boot up, your Mac’s hardware status is under your control.

III. Advanced Tips for Common Functions

• Link Fans: In the fan control area, there is a “Link Fans” button. When enabled, manual speed adjustment of one fan will automatically synchronize to all other fans, ensuring balanced heat dissipation. This feature is particularly useful on multi-fan MacBook Pros, avoiding abnormal wind noise caused by inconsistent fan speeds on both sides.
• Focus on Key Temperatures: For most Macs, the “CPU Proximity” and “GPU Proximity” sensors best reflect the overall temperature of key areas on the logic board and are ideal references for setting automatic fan rules.
• Menu Bar Customization: In Preferences > General, you can set the temperature type displayed in the menu bar (such as maximum CPU temperature or GPU temperature) to better suit your monitoring needs.
• Safe Mode: If fan control behaves abnormally (such as fans continuously running at full speed), you can restart your Mac and launch TG Pro in Safe Mode, which usually resets the fan control driver.

IV. Common Issues and Solutions

4.1 Fan Speed Shows “0” or “N/A”

Issue: Some Mac models or specific fans may not be readable.

Solution:

1. Confirm your Mac model is in TG Pro’s supported list.
2. Try selecting Help > Reinstall Fan Helper in TG Pro’s menu bar to reinstall the fan control helper tool, then restart TG Pro.
3. Ensure no other hardware monitoring software (such as smcFanControl) is running simultaneously to avoid conflicts.

4.2 Automatic Fan Control Rules Not Working

Issue: Rules are set but fan speed does not increase as expected.

Solution:

1. Check whether “Enable custom fan control” is checked in Preferences > Fans.
2. Confirm the current fan control mode is “Auto”. Rules are invalid in manual mode.
3. Check whether the rule conditions are too loose (threshold set too high) and the current sensor temperature has not reached the trigger point.

4.3 Menu Bar Icon Not Showing

Issue: After launching TG Pro, its icon does not appear in the menu bar.

Solution:

1. Go to System Preferences > Dock & Menu Bar, find “TG Pro” in the left list, and check whether it is set to show in the menu bar.
2. In TG Pro’s Preferences > General, confirm the “Show TG Pro in menu bar” option is enabled.

4.4 How to Restore Factory Settings?

Issue: Too many settings have been adjusted and you want to restore to initial state.

Solution: You can reset TG Pro’s preferences via Terminal command. Open the “Terminal” app, enter the following command and press Enter: defaults delete com.tunabellysoftware.TGPro. Then restart TG Pro, and all settings will be restored to default values.

4.5 Software Prompts “Unable to Access System Management Controller (SMC)”

Issue: TG Pro cannot obtain hardware control permissions.

Solution: This usually occurs on newer Mac models or specific system versions. Please ensure that in System Preferences’ “Security & Privacy”, TG Pro has been granted “Accessibility” and “Full Disk Access” permissions. If the problem persists, try restarting your Mac and resetting the SMC (reset methods vary slightly for different chip Macs; refer to Apple’s official support documentation).
