At the WWDC20 keynote, Apple unveiled macOS Big Sur, the next version of the Macintosh operating system. Big Sur will replace macOS 10.15 Catalina this fall. Please do NOT update to Big Sur until you’re ABSOLUTELY POSITIVE all your existing software is compatible with macOS 11 Big Sur.
Sony camera owners should be particularly wary of updating since Sony firmware updates released prior to macOS version updates are generally not compatible with the next macOS.
Sony camera owners should NOT update to Big Sur until all Sony camera & lens firmware is updated. Please make certain the firmware on every Sony camera & lens you own is updated BEFORE even considering macOS Big Sur update.
If you use Imaging Edge or Capture One, do NOT update until Big Sur compatible updates are available.
• Sony firmware updates released prior to Big Sur will NOT be compatible with macOS Big Sur
• Imaging Edge Remote tethering will NOT be compatible with macOS Big Sur upon release
• Capture One Pro tethering will NOT be compatible with macOS Big Sur upon release
Make certain you’ve turned off Automatic macOS Updates in System Preferences > Software Updates
Uncheck ‘Automatically keep my Mac up to date’ then click ‘Advanced…’ and make certain ‘Install macOS updates’ is NOT checked.
