macOS Big Sur Support & Apple Mac Upgrade Help in London

Still using macOS Big Sur on an older Intel-based Apple Mac? Big Sur reached end of support in September 2023, meaning no more security updates or compatibility improvements. If your Mac is slowing down or struggling with modern apps, now is the time to upgrade.

macOS Big Sur System Requirements

  • MacBook (2015 and later)
  • MacBook Air (2013 and later)
  • MacBook Pro (Late 2013 and later)
  • iMac (2014 and later)
  • iMac Pro (2017)
  • Mac mini (2014 and later)
  • Mac Pro (2013 and later)

If your Mac is on this list, it’s likely running outdated hardware. Apple Silicon M4 Macs offer a major leap in speed, battery life, and future compatibility.
