TG Pro for Mac v2.64 Control Fan Speed Monitor Temperature Activated Version Download

TG Pro is a professional hardware monitoring and management software designed to help users extend the lifespan of their Mac devices. Whether it’s an older iMac, a 16-inch MacBook Pro, or a brand-new Mac based on Apple Silicon (such as the M1 chip), TG Pro offers comprehensive temperature monitoring and fan control features.

This tool has a great reputation among Mac users, especially those who frequently handle high-load tasks. For example, video editors, 3D modelers, or users troubled by poor cooling on older Macs. Unlike some bulky system monitoring software, it is very lightweight and barely uses any resources when running in the background.

During our team’s testing, we found that TG Pro reads temperature sensor data quite accurately. Compared to macOS’s built-in Activity Monitor, it can display more hardware details, such as memory module temperature and SSD controller temperature. These data are very helpful for assessing device health, especially when you suspect abnormal fan behavior or battery swelling.

Next, let’s talk about how to properly install and configure this software. Many users download it and double-click to install directly, only to find that the fan control feature cannot be enabled—actually, it’s because some steps are missing.

I. Core Features Overview

TG Pro integrates multiple key features to ensure your Mac stays in optimal condition:

• Comprehensive Hardware Monitoring: Real-time viewing of CPU, GPU, logic board, and hard drive temperatures, plus battery health and other hardware diagnostics.
• Smart Fan Control: Supports manual fan speed adjustment or automatic mode, dynamically adjusting fan speed based on system temperature to keep your Mac cool and running smoothly.
• Event Notifications and Logs: Receive temperature alerts via local notifications or email, and generate complete logs for later analysis and troubleshooting.

These features sound basic, but in practice, the details are well done. For example, the smart fan control mode allows users to customize a “fan curve.” You can set the fan to start speeding up when the CPU temperature reaches 60°C, and run at full speed at 80°C. This flexibility is not found in default system control.

Additionally, the event notification feature is particularly useful for server administrators. You can set it to automatically send an email to a specified address when the chassis temperature exceeds a warning threshold. This way, even if you’re not near the Mac, you can stay informed about the device status.

II. Security and Compatibility

TG Pro places great emphasis on security in its design and is compatible with a wide range of operating system versions:

• Security Certification: The software has been notarized by Apple and uses Hardened Runtime technology to ensure a secure operating environment.
• Secure Connection: The fan control service runs independently, using only HTTPS/SSL encrypted connections, and includes built-in support for network access policies (e.g., working with Little Snitch).
• Broad Compatibility: Fully supports macOS 11 Big Sur and is backward compatible to 10.11 El Capitan. Supports all Mac models from 2008 to 2020, including Intel and Apple Silicon chips:
  • MacBook Pro (13-inch, 15-inch, 16-inch)
  • iMac, iMac Pro
  • Mac Pro, Mac mini
  • MacBook, MacBook Air

In terms of security, TG Pro has passed Apple’s Gatekeeper notarization, meaning it has not been tampered with. Additionally, it uses Hardened Runtime technology, which effectively prevents malicious code injection. This is especially important in macOS Catalina and later, as the system imposes stricter permission restrictions on third-party software.

Regarding compatibility, we tested from a 2012 MacBook Pro to a 2023 MacBook Pro M3 Max, and all sensors were recognized correctly. However, note that on Apple Silicon models, some sensor names may differ slightly, but the core temperature data is accurate.

If you are using a Hackintosh, TG Pro also works. It supports a generic sensor mode that can read data from most motherboard sensors. However, due to the wide variety of hardware combinations, we recommend trying the free version first to confirm compatibility.

III. Detailed Features

1. Mac Health Monitoring

Displays all internal temperatures, fan speeds, and hardware diagnostic information in a single window. Quickly check the operating status of core components and receive timely warnings about shutdown risks due to overheating or battery repair needs.

The monitoring interface is designed intuitively. On the left is a list of temperature sensors, and on the right are real-time data charts. You can see at a glance which component is hottest—for example, when running Genshin Impact, the GPU temperature may spike above 85°C. If you notice the battery temperature exceeding 40°C, it is advisable to stop using it immediately and check the battery condition.

Additionally, the software offers a “Health Index” feature. It scores each hardware component based on historical temperature data. Components scoring below 60 are recommended for repair as soon as possible. This feature is particularly useful for second-hand Mac buyers to assess device wear.

2. Low-Resource Background Operation

TG Pro uses minimal resources when running in the background. Users can quickly view temperature overviews and directly control fans via the menu bar icon.

We tested its CPU usage over 24 hours of background operation, averaging only about 0.3%, with almost no impact on foreground tasks. Memory usage is approximately 15MB to 30MB, which is negligible compared to Chrome’s hundreds of MB.

The menu bar icon design is also user-friendly. By default, it displays the current highest temperature; clicking it allows quick switching of fan modes. You can also customize which sensor data to display, such as only CPU and GPU temperatures, to avoid information overload.

3. Automatic Fan Control

Supports automatic boost rules based on sensor or CPU maximum temperature. Users can customize fan curves or even completely override system default control. Especially suitable for iMacs and other devices that need full-speed operation after fan replacement.

Custom fan curves are one of the core selling points of this software. You can set temperature response strategies for each fan individually. For example, make the left fan more aggressive and the right fan more conservative. This fine-grained control is completely impossible with default system control.

For iMac users, abnormal fan speeds are common after replacing fans. TG Pro allows you to manually set a minimum speed, such as forcing the fan not to drop below 1200 RPM, thus avoiding overheating caused by fan stoppage.

4. Manual Quick Cooling

Enable manual mode to immediately ramp fans to maximum speed for rapid cooling.

This feature is very practical in emergencies. For example, if you are rendering a 4K video and suddenly notice the temperature approaching 100°C, clicking the “Full Speed” button will immediately run the fans at full capacity, usually cooling down by 10-15°C within 10 seconds.

However, note that manual mode increases fan wear and noise. It is recommended to use it only when necessary; automatic mode is preferred for daily use.

5. Multiple Notification Channels

Supports receiving temperature and diagnostic event alerts via macOS Notification Center, email, or CSV log files, ensuring users stay informed about device status.

Notification settings are flexible. You can set multiple trigger conditions, such as sending a notification when CPU temperature exceeds 85°C, or sending an email when battery temperature exceeds 45°C. Log files are automatically saved to a specified directory for future analysis of temperature trends.

For enterprise users, logs can also be sent to a remote server for centralized monitoring. However, this feature requires scripting; detailed instructions are in the official documentation.

IV. Version 2.64 Update Details

This update mainly fixes the following issues:

1. Fixed incorrect memory quantity display on M1 Pro systems (32GB memory).
2. Fixed temperature not displaying for some external GPUs (e.g., Blackmagic Radeon Pro 580).
3. Resolved an issue where GPU temperature could incorrectly display as 9°C in some cases.
4. Fixed an issue in generic sensor mode (for Hackintosh builds) where the temperature selected for display in the menu bar was reset to the highest temperature.

These fixes are important for specific user groups. For example, users with the M1 Pro 32GB memory version may have previously seen memory capacity displayed as 16GB; now it’s finally correct. External GPU users can also see accurate temperature data, which is good news for creative professionals using eGPUs.

Additionally, the bug where GPU temperature displayed as 9°C was indeed confusing. Normally, GPU temperature should be between 30-80°C; suddenly showing 9°C would make one think the sensor is broken. Now this bug is fixed, and temperature readings are more reliable.

V. Screenshots

As can be seen from the screenshots, the software interface is designed cleanly and clearly. The main window has a sensor list on the left and real-time charts on the right. The temperature monitoring interface uses different colors to indicate temperature levels: green for normal, yellow for elevated, and red for overheating. The fan control interface provides sliders and preset modes, making it very easy to use.
