When I upgraded to Yosemite the "Temperature Monitor" quit. How do I go about getting it back ? I tried the internet it stated i had to download a bunch of junk to get it.
When I upgraded to OS X 10.9.5, same thing happened to me too. I then switched to iStat Pro until I found this link recently. I just needed to download the 4.98 version and everything was back to normal. Since I did not test it in Yosemite, your mileage may vary though.When I upgraded to Yosemite the "Temperature Monitor" quit. How do I go about getting it back ?
cpuLED is a nice program that displays small indicators for each of your cpu cores. It has 4 green icons at normal temp, and they change color based on temperature.
