Tg Pro (temperature Gauge Pro) 2.50 | Free Forever |

Ability to monitor and manually boost fan speeds.

As Apple transitioned from Intel to their own silicon (M1, M2), users found their new machines to be incredibly efficient but still capable of running hot under heavy loads like video editing or compiling code. TG Pro (Temperature Gauge Pro) 2.50

Built-in checks to see if sensors or fans were failing. Ability to monitor and manually boost fan speeds

TG Pro continued to iterate heavily after this version to support M2, M3, and now M4/M5 chips, but the 2.50 era established it as a must-have utility for the early Apple Silicon adoption phase. Tunabelly Software Blog TG Pro continued to iterate heavily after this

It included the ability to fix the noisy fan issue that occurred after replacing the hard drive in older Intel iMacs.

While Apple Silicon ran cooler, users still faced thermal throttling, and the default fan control was designed for silence, not max performance. Furthermore, specialized new hardware (like M1 iMacs and early M1 Mac minis) needed tailored monitoring.

The core story of this version was its enhanced Auto Boost feature. Users could set custom fan rules to boost speeds before the Mac became too hot, maintaining peak performance during intense workflows. Key Features Highlighted in this Era
