Apple revealed that OS X El Capitan, the latest major release for Mac OS, will be available tomorrow as a free update.
Starting Wednesday, September 30, users can download the new OS X installation from the Mac App Store for free. El Capitan supports all Macs introduced since 2009, and some older models from 2007 and 2008.
Apple boasts several performance improvements with the new OS, including the addition of Metal, Apple's proprietary (what isn't proprietary from Apple?) graphics acceleration technology, which is said to deliver up to a 50 percent boost to system-level rendering and up to 40 percent more graphics efficiency. Metal also offers up to 10 times faster draw call performance, according to the company.

Along with improvements to Mission Control, Safari and Spotlight, Apple rolled out an all-new app called Notes. Notes lets you drag and drop photos, PDFs, videos and other files or Internet content into a note that can be shared or synced with iCloud. This new "innovation" is rather useful, but we can't help feeling we have seen it before somewhere (cough, OneNote, cough).
