macOS 11, also known as Big Sur was released on Thursday, November 12th, 2020. Big Sur is is a free update from Apple. It will run on most any Mac made since 2013, however we consider this a major OS release. Big Sur sports a refined interface, and under the hood removes older technology which can break compatability with applications, while adding support for Apple’s new silicon processors. NRGship for UPS has been tested under Big Sur however we highly suggest users wait to upgrade to ensure compatibility across all installed applications.
