Pointer lagging at OpenCanopy, FileVault 2 / Takes a lot of time to show FileVault Preboot UI (Solved - OpenCore 0.7.7)

  • According vit9696: 
    The issue with Dell laptops is generally pointer polling, which is touchpad polling for a laptop.
For some reason touchpads on Dell are often very slow to respond to GetState.
  • Basically, after choosing macOS at OpenCanopy, you may need to wait around ~3 minutes for FileVault UI showing up. You can trigger the touchpad at Apple logo, then FileVault UI will show up after that. The reason is because of Dell's firmware.
  • This issue is resolved with new OpenCore.efi at commit ee28077.
