Apple has released OS X 10.11 El Capitan. It is available as a free download from the App Store. Initial reports are that it is quite stable, but if you use any third party applications or hardware, you should not install 10.11 until they have been verified as compatible, or until they have been updated for the new system.
It will run on most Macs from 2007 onwards. You will need roughly 8GB of free hard drive space and although Apple list 2GB as the minimum RAM requirement, performance will improve with 8GB or more. Don’t forget to back up your computer before installing a new operating system.
New features include:
– Split view applications
– ‘Find mode’ for cursor making it easier to see on a large screen
– Improved Mail app performance
– Maps now shared directions with iPhones
– Notes app allows you to create checklists and add attachments
– Photos app now supports third-party extensions
