Resolving the Brief Flash and Login Screen Return
When the 'Install macOS' option disappears instantly on your 2017 MacBook Air, it's usually because the SIP (System Integrity Protection) or Secure Boot variables are blocking the patched kernel.
The Fix:
- NVRAM Reset: This is mandatory. Hold Cmd+Opt+P+R for two chimes to clear the 'stuck' boot entries.
- OCLP Settings: Open the OCLP app, go to Settings, and ensure 'Allow Native Overrides' is checked. Re-build and install OpenCore to your disk.
- The 5-Second Rule: When the boot picker appears, wait 5 seconds before selecting the EFI Boot. This allows the UEFI drivers to fully initialize the USB partition.
Original Question: "MacBook Air 2017 — Ventura install via OCLP flashes briefly then returns to login screen"
 | I'm trying to install macOS Ventura on my MacBook Air 2017 using OpenCore Legacy Patcher. I've already created the installer and applied the patcher to the disk. When I restart and hold the Option key, the boot picker does appear, so I select EFI Boot. According to the official guide, I expect to see a second boot option (the non-EFI one) that lets me proceed with the Ventura installation (the one that I have attached above). It does show up briefly, but disappears almost instantly and sends me back to the regular login screen. What am I missing here? [link] [comments] |
