Version 2.0.4 of FolderWatch (iTunes link) was released on the Mac App Store on Friday. First discovered by The Next Web, one of the new features of the latest update from developer Brothers Roloff is "Retina graphics."
It's unknown whether the developer was informed ahead of time about Retina displays expected to be coming to new Macs next week, or if Brothers Roloff simply assumed and prepared their application accordingly. FolderWatch was featured as an "Apple Staff Favorite" on the Mac App Store in June of 2011.
The update issued to the $11.99 application on Friday comes only days before Apple is scheduled to hold a keynote address on Monday, June 11, at the Moscone Center at 10 a.m. Pacific, 1 p.m. Eastern. AppleInsider revealed this week that Apple is expected to refresh its 15-inch MacBook Pro, 11- and 13-inch MacBook Airs, 21.5- and 27.-inch iMacs, and Mac Pros.
Rumors leading up to this year's WWDC event have claimed Apple will introduce a redesigned MacBook Pro with a thinner form factor and new high-resolution Retina display, just like the pixel packing screens already found on the iPhone, iPod touch and iPad. Reports have also claimed that the iMac will be receiving an upgrade to a Retina display.
Since last year, rumors have persisted claiming that Apple was working on a Retina Display laptop. Offering further evidence to a possible Retina Display MacBook are the latest OS X Lion updates which brought Hi-DPI UI assets in 10.7.3 and doubled icon resolution in 10.7.4.
Some icons featured in the latest version of Lion quietly feature new double-resolution 1,024-by-1,024-pixel icons, including TextEdit, App Store and LaunchPad. However, not all applications have seen their icons grow beyond 512 by 512 pixels.
