Although it is possible to run AFMG SysTune in a well-configured virtual machine, AFMG does not recommend running SysTune within a virtual machine like Parallels.

Under virtual machines there are often latency issues and consequent instability with the measurements.  We cannot guarantee in all cases that SysTune will work within a virtual machine, as the stability also depends on the computer’s performance, the settings defined by the user for the virtual machine, and other software and/or drivers installed. The possible settings are so diverse that AFMG cannot give specific advice.

Therefore, Boot Camp should always be used to perform/acquire measurements without additional system related problems.
