I've been using this application successfully for several years in a PowerMac G4 mirrored doors computer. Because I have a video card that runs hot, I position the PowerMac on the desktop with an air conditioner blowing cold air into the rear vents to keep the motherboard and the video card running cool. It's fun to see the short term and long curve temperature curves, and it gives me a sense of security to know when the Mac might be getting close to its designed upper limits. This nice little utility is the first thing I launch when I boot up, and I keep it running all the time the PowerMac is in use.

Highly recommended to give you piece of mind about what going's on in your computer's innards

I'll be installing it in a mid-2012 Mac Pro soon to see how it works there, too.

According to the developers website, this software only works on Macs released between August 2002 and October 2012. It won't work on Macs released since November 2012. Is there a reason for not working on the latest Macs?

I would expect because it has to be updated with the information concerning the sensors from the newer models.

If you just bought a mac your temps will be about 10 C higher in the first 2 weeks. My Macbook Pro 2012 Retina was usually running at around 52 - 54 C on idle, that was its average temp for the first 1-2 weeks, right now it hovers at 40-43 C on idle. I only watch the core temps of any computer I own, as I have a PC and that is where I also always measure my temps with "Core Temp".

Also if you just upgraded your OS you will have higher temps. I also found that chrome causes much higher temps in youtube than Safari (20C difference playing the same clip on youtube.)

I want to watch the temperatures on my mac to make sure it does not overheat, this allows me to do exactly that, and free to boot!

Although MacUpdate identifies Temperature Monitor version 4.94, the downloads are actually version 4.95.

I don't know why I keep looking at this every few months. It's always disappointing. Run temp monitors in windows on the same machine...several of them...and they all report 5 to 10 degrees less than this junk. I can't believe this machine runs at 50-55 at idle and it doesn't but this app lies and tells me it does. As I said before...having an app that doesn't work and offering it as one that does is worse than not having one at all, FREE or not. Someone PLEEEEASE come up with something besides this joke for Macs!

FYI, although Macupdate claims the latest version is 4.93, 4.94 has been out since March.

and another comment. On a i7 for some reason it is reading core 1-5 sometimes, and other times reading core 7 and 8, and most of the time it's dropping out at least one or two and not even showing them. Hmmm...I believe a quad is a quad. Why would it even read more than 4 cores? But it does. Why would it continually drop out and read the WRONG cores? Ever since I've started playing with this "tool" I have lamented that there are NO good temp monitors for Mac at all, just this junky one that really doesn't function as advertised. For the life of me I have no idea why people even bother to download it..because it it one of the poorest pieces of junk for the Mac I've ever seen. Better to have nothing at all than to have something that gives bad readings, incorrect readings, and even reads things that ARE NOT EVEN THERE.

Don't bother with this.

Free yes. Whatever enhancements were made to improve montoring of quad cores really did nothing, it still only displays the temp of core 1 and 2 most of the time. Every now and then Core 3 and Core 4 will blink on for about 10 seconds, then go away again.

Still needs work to be good with any quad

Been using this gem for the past 31/2 years, first on my Powerbook and now on my MacBook Pro Intel core2 Duo. It's always worked perfectly for me with never a hint of trouble. The developer, Marcel Bresink is a real pro; he really knows his craft. I have the utmost respect for him.
This beautifully done little work of art is well worth its very modest cost of, currently, €7 (a little more than $10 US.). I'd say it's a real bargain.

Whoops, I meant this review for Hardware Monitor,however I've used Temperature Monitor before and found it, too, exemplary.
