Menu bar & system utilities
TG Pro does two things. It reads every temperature sensor macOS exposes — CPU, GPU, SSD, battery, enclosure — and it takes the fans off Apple's curve. You can pin a couple of readings plus fan RPM in the menu bar, hold the fans at a fixed speed, or write rules along the lines of "when the GPU passes 80C, go to full". It is what people install when a long export throttles and the fans are still loafing.
The price deserves a careful read. The page shows $10 as a one-time payment, marked down 50% from $20, so the honest version is "ten now, twenty if the promotion ends". There is no subscription. There is also no stated policy on major-version upgrades, which means a paid upgrade later is possible rather than promised — worth knowing at this price, not a reason to hesitate.
Skip it if your Mac has no fans: on a MacBook Air you get a temperature readout and no control, and free monitors cover that. Skip it too if you only want to glance at a number occasionally. It pays for itself on a fan-equipped Mac that throttles under sustained load, where a manual curve is the difference between finishing the render and waiting on the thermal ceiling.
