Mac App Store users browsing the software shop tonight are starting to notice a few aesthetic changes, as seen in the screenshots above and below. Like the recent iTunes Store facelift, the Mac App Store redesign features lighter fonts, a sparse white background, and thin gray separators.
The updated design is currently showing up every few minutes on the throughout the store, though it still shows the old design on many pages just as much as the new. The iTunes Store had a similar issue when it was updated last month, and once the rollout is complete the new design will be available to everyone. A few elements such as the “Update” button are also still using the old style.
