I upgraded to the ‘Pro’ version and was impressed with the user interface, all the fan control and the monitoring of sensors throughout this little system. This little system has two 1 Tb SSD drives and max memory and runs like clockwork with Parallels and Windows 8/Office 2013. It wasn’t long before I noticed the temperatures creeping up around the processor. Then the fans would speed up to a roar and Yosemite started shutting down applications! The mac mini case felt as hot as a frying pan. Everything returned to normal after I removed TG Pro - the little system immediatley starting running cool again. I don’t know what this application was doing to cause such intense CPU activity (I assume) but it is DANGEROUS so be warned.
