A Python-based GUI application that builds and installs OpenCore boot configurations to run modern macOS (Big Sur through Sequoia) on unsupported, older Macs as far back as 2007. It patches drivers and unlocks features like graphics acceleration, Sidecar, and AirPlay while preserving OTA system updates.

Use cases

  • install macOS Sequoia on a 2012 MacBook Pro
  • get Metal graphics acceleration on an old Mac
  • run Big Sur on an unsupported Mac from 2008
  • enable Sidecar and AirPlay to Mac on older hardware
  • keep receiving OTA macOS updates on a legacy Mac
  • revive an old iMac with a newer macOS version

When to choose

  • you own a Penryn-or-newer Mac no longer supported by Apple and want to run Big Sur or newer
  • you want native OTA updates, FileVault, and SIP on unsupported hardware
  • you need graphics acceleration or unlocked features like Sidecar on old Macs

When to avoid

  • you want to run macOS on non-Apple (PC) hardware - use standard hackintosh tools instead
  • you need macOS Mojave or Catalina support - dosdude1's patchers are recommended
  • your install was already patched with other tools like Patched Sur - clean install required
