TG Pro for Mac v2.71 Control Fan Speed Monitor Temperature Activated Version Download

TG Pro is a professional hardware monitoring and management tool designed to help users extend the lifespan of their Mac devices and optimize performance through comprehensive hardware status monitoring and intelligent fan control. Whether it’s an older iMac, a 16-inch MacBook Pro, or a new Mac based on Apple Silicon (such as M-series chips), TG Pro provides full compatibility support.

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, along with battery health and other hardware diagnostics.
• Intelligent fan control: Supports manually increasing fan speeds or setting automatic rules based on temperature thresholds to ensure your Mac stays cool and efficient under high loads.
• Real-time notifications and logs: Receive temperature event alerts via macOS Notification Center or email, and generate detailed CSV log files for in-depth analysis and troubleshooting.

II. Security, Compatibility, and Installation Tutorial

TG Pro prioritizes security from the ground up:

• Notarized by Apple and uses Hardened Runtime security technology to ensure the software is from a trusted source and safe at runtime.
• Fan control is implemented through a separate secure service to ensure system stability and avoid conflicts.
• Only uses HTTPS/SSL encrypted connections for necessary network communication and includes built-in support for network access policy tools (such as Little Snitch).
• Broad compatibility: Fully supports operating systems from macOS 10.11 El Capitan to the latest versions (including macOS 13 Ventura and later).

Detailed Installation Steps

Step 1: After downloading, double-click the .dmg file to mount the disk image. An installation window will pop up containing the TG Pro icon and an Applications folder shortcut.

Step 2: Drag the TG Pro icon to the Applications folder on the right. This will copy the program to your Mac’s hard drive, completing the core installation.

Step 3: On first launch, macOS may prompt “Cannot verify developer.” Please go to “System Preferences” > “Security & Privacy” and click the “Open Anyway” button.

Step 4: After launching, TG Pro will request accessibility permissions. Click “Open System Preferences” in the system popup and check the box next to TG Pro.

Step 5: After granting permissions, the software’s main interface will load automatically. You can see the TG Pro icon in the menu bar; click it to expand the temperature overview and fan control options.

Step 6: It is recommended to update to the latest version immediately. Click the menu bar icon and select “Check for Updates” to ensure you have the latest hardware database and bug fixes.

Step 7: To uninstall, simply move TG Pro from the Applications folder to the Trash and empty it. Residual preference files are located at ~/Library/Preferences/com.tunabellysoftware.TGPro.plist.

III. Supported Mac Models

TG Pro supports a wide range of Mac devices from 2008 to the latest models, covering both Intel and Apple Silicon architectures, including but not limited to:

• MacBook Pro (13-inch, 14-inch, 15-inch, 16-inch)
• iMac, iMac Pro
• Mac Pro
• MacBook, MacBook Air
• Mac mini
• Mac Studio

IV. Key Features Detailed

1. Comprehensive Mac Health Monitoring

Displays all internal temperatures, fan speeds, and hardware diagnostic information in a single window. Users can easily determine whether core components are functioning properly and receive warnings about shutdown risks due to overheating or battery repair needs.

2. Low-Resource Background Operation

TG Pro runs continuously in the background with minimal resource usage. Users can quickly view temperature overviews and perform fan control operations via the menu bar icon without interrupting their current work.

3. Automatic Fan Control Strategies

Customize “Auto Boost” rules based on sensors or maximum CPU temperature to intelligently adjust fan speeds. This feature can completely override the system’s default control to achieve custom fan curves, especially suitable for iMac calibration after replacing cooling fans.

4. Manual Rapid Cooling

Enable manual mode to immediately boost fans to maximum speed for rapid cooling during sudden high-load tasks.

5. Multi-Channel Event Notifications

Supports receiving temperature anomalies and hardware diagnostic events via macOS Notification Center, email, or CSV log files, ensuring users stay informed about device status at all times.

V. Version 2.71 Update Details

• [New] Full support for MacBook Air (M2, 2022).
• [New] Enhanced compatibility with macOS 13.
• [Fixed] On macOS 13, repeated prompts to install the fan helper even when it is already up to date.
• [Fixed] On some M1 Pro/Max/Ultra and M2 models, GPU temperature incorrectly reported as 5°C or 104°C.

VII. FAQ

Q1: Does TG Pro support Macs with M1/M2 chips?

Fully supported. TG Pro version 2.71 is natively optimized for Apple Silicon architecture and can accurately read temperature sensors on M-series chips.

Q2: Installation shows “Cannot open” – how to fix?

This is due to macOS security restrictions. Please go to “System Preferences” > “Security & Privacy” and click “Open Anyway.” If the issue persists, try right-clicking the TG Pro icon and selecting “Open.”

Q3: Does fan control affect Mac warranty?

No. TG Pro only adjusts fan speeds at the software level and does not modify hardware firmware. Apple’s official repair policy does not list third-party fan control software as a reason for warranty denial.

Q4: Why aren’t my automatic fan rules taking effect?

Please check whether TG Pro has been granted permission in “Accessibility.” Also, ensure that “Auto Boost” is enabled and temperature thresholds are set reasonably.

Q5: Does TG Pro consume a lot of battery?

No. When running in the background, TG Pro typically uses less than 1% CPU, with negligible impact on battery life.

Q6: Can multiple fans be controlled simultaneously?

Yes. For Mac models with multiple fans (such as the 16-inch MacBook Pro), TG Pro supports independent control of each fan’s speed.

Q7: Where are log files saved?

By default, they are saved in ~/Library/Application Support/TG Pro/Logs/ in CSV format, which can be opened and analyzed with Excel or Numbers.

Q8: How to restore default system fan control?

Simply quit TG Pro or disable the “Auto Boost” feature, and the system will automatically take over fan control strategies.

Q9: What languages does TG Pro support?

Currently, the interface is primarily in English. However, data such as temperatures and fan speeds are displayed numerically, so it does not affect usage.

Q10: Can I use it on multiple Macs after purchase?

TG Pro’s license agreement is for a single user and single device. To use on multiple Macs, multiple licenses must be purchased.
