No, I'm not saying testing on computers other than Macs is wrong -- to the opposite, I think it must always be done (except maybe specifically in cases like this when you are looking for an audience of those who want to do design). Design isn't about looking "beautiful". Design is (1) usability, (2) propaganda that relies on your audience's associative brain (peripheral cognition) to position the product into the realm of "desirable". Right now, in the minds of most people who matter, Apple designs are more desirable than air. So if the designer you're hiring hasn't figured that part out yet, his/her value to your company will be negative.
