'ZDNet Recommends': What exactly does it mean?
ZDNet's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNet nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNet's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form.
There are a bunch of software utilities that are the first things that I'll install on a new Mac, and among those is Tunabelly Software's TG Pro. This utility is a one-stop shop for temperature monitoring, fan control, and diagnostics for all Macs.
Well, if you happened to pick up one of the new M2-powered Macs, then TG Pro now supports this new chip.
Doesn't macOS already do a good job of thermal control?
Yes, but professionals who push their hardware to the limits with heavyweight tasks such as video rendering will benefit from having manual control over the thermals.
And even if you don't want to control the fans, you can use TG Pro to keep an eye on the various temperature sensors inside your Mac. This can give you an advanced warning of possible problems.
According to the maker, "many changes were needed to properly show the 4 Performance and 4 Efficiency CPU cores in the M2, along with figuring out which sensors were for which pieces of hardware - it was a tricky one."
Here are the release notes for TG Pro 2.70
[New] Added full support for the MacBook Pro (13-inch, M2, 2022).
[New] Added an additional way to check for the last shutdown reason for newer models.
[Fixed] Issue where the menu bar icon may have been blurry. It will now be sharp for any screen resolution.
[Fixed] Updated the Paddle framework used for licensing. This should resolve the rare issue of a license disappearing after a system restart.
Note: TG Pro now requires macOS 10.12 or higher due to the Paddle licensing framework update.
