So last night upon watching Microsoft’s new “I’m a PC” ads, I half-jokingly asked how long it would be until one of the celebrities in the clips was spotted using a Mac? As quite a few commenters noted, many of the celebs had been seen with Macs previously, but today brings something far more humorous. Apparently, the commercials themselves were made using Apple computers!

A Flickr user, LuisDS, was able to dig into one of the videos’ metadata and found that evidence of Apple’s OS X operating system all over it, according to AppleInsider. To add insult to injury, apparently Microsoft also didn’t use its own Expressions Studio for the work, and instead opted to use software by rival Adobe.

Ouch.

It’s possible the Flickr user who found this data could have faked it, or that it could have come from somewhere else. But if this is true, this just does not look good at all for Microsoft as it perfectly plays into Apple’s “I’m a Mac versus I’m a PC” ads, which underscore ease-of-use and functionality of the Mac platform. Microsoft (or at least their ad agency), it seems, may agree.

Update: The official word from Microsoft (via Digital Daily):

As is common in almost all campaign workflow, agencies and production houses use a wide variety of software and hardware to create, edit and distribute content, including both Macs and PCs.
