A team of German researchers took data from 30 brain scans and analyzed them using a package called FreeSurfer—one of the major medical image analysis programs, which can be used to measure the size of different parts of the brain.
They ran the software on PCs, and also on Macs running different versions of Mac OS, each time using the software to measure the size and thickness of various structures of the brain. They found that not only did PC and Mac OS installs of the software throw up different results—but the version of Mac OS also had an impact.
Across most sections there was at least a 2-5 percent variation in the answers. But in the parahippocampal and entorhinal cortex, the answers diverged by as much as 15 percent. A 15 percent variation just because of a Mac OS update. The results appear in PLoS One.
