Apple announced OS X Yosemite along with iOS 8 last Monday and designers are already coming up with beautiful app concepts and gorgeous icon designs for some existing Mac apps. In OS X Yosemite, along with the overall design changes, the apps are also overhauled to match the flat interface. You can head over to Min Ming Lo's nice overview of what has visually changed in Yosemite, and I totally agree with what’s written in the Good, the Okay and the Bad sections. Apple should really change the folder icon in Yosemite before they release it for everyone.
With OS X Yosemite’s new design, it is very important that existing apps should be updated not only to add Yosemite support but also to match the new flat design of Yosemite. Developers can also use the new extensions to improve their existing apps and add new features to their apps.
Apple will release Yosemite for public in the next few months and by then, I am sure we will be seeing lots of app updates. In fact, I am sure developers of some popular apps have already started working on updates. If you’re wondering how popular apps will look like on Yosemite, check the list below which includes some of my favorite app concept designs from Dribbble.
