William "Wil" Jon Shipley (born October 16, 1969) is a Macintosh software developer, best known for co-founding and heading The Omni Group in 1991, where he did consulting work and developed software for the NeXTSTEP operating system, Rhapsody and later Mac OS X.
His firm was one of a relative few to develop for Rhapsody, with the company's OmniWeb becoming the most popular browser for the platform.
In 2007 Wil and Lucas Newman wrote a new algorithm that did not require cameras with variable focus lenses, thus pioneering blurry one-dimensional barcode reading ("reverse image deconvolution") using ideas from Belgian astronomers.
In 2005, Shipley gave a talk entitled "How to Succeed Writing Mac Software" at WWDC and in 2007 spoke at C4 about using "the hype machine" to your company's advantage.
On September 27, 2021, Shipley announced on Twitter that he had joined Apple as of that day, as Senior iOS Home Application Engineer.
