Tg Pro | (temperature Gauge Pro) 2.50

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

The updates surrounding 2.50 focused on unlocking that potential. It brought full support for M1 Macs, offering more temperature sensors than any other app—including GPU, CPU, SSD, and battery.

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 It included the ability to fix the noisy

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. Built-in checks to see if sensors or fans were failing

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.
