How to Fix Adobe photoshop crash iMac late 2015 Sequoia 15.1.1 OCLP 2.1.2 During macOS Boot or Installation

Boot failures need a predictable pass through firmware, USB, storage, EFI and verbose logs before reinstalling macOS. Most installer stalls come from firmware settings, an invalid config.plist, wrong SSDTs, bad USB mapping or unsupported storage/controller settings.

Quick Checks

  • Backup current state: Save a copy of your working EFI and run a full system backup before changing settings.
  • Identify hardware components: Note down your exact CPU, GPU, Wi-Fi card, and motherboard/laptop model.
  • Ensure utility alignment: Keep OpenCore, OCLP, and ProperTree updated.

Fix Steps

  1. Create a rollback point: Make a Time Machine backup and keep a copy of your last working EFI folder before editing OpenCore, kexts or root patches.
  2. Boot verbose: Add -v keepsyms=1 debug=0x100 so the final visible line gives a real clue.
  3. Check firmware settings: Disable Secure Boot and Fast Boot, set SATA to AHCI, disable CFG Lock if possible, and use UEFI mode.
  4. Validate OpenCore: Update OpenCore, Lilu and core kexts, then run ocvalidate or ProperTree clean snapshot.
  5. Recreate the installer: Use a fresh USB installer and try another USB port; older Macs may need a USB 2.0 hub for input during setup.
  6. Reset NVRAM: Reset NVRAM from the OpenCore picker before retrying the installer.

Verify It Worked

  • Verbose boot moves past the previous stopping line.
  • The installer reaches Disk Utility and sees the target disk.
  • Keyboard, mouse and USB remain active during recovery.
  • OpenCore picker still loads after a cold boot.

Rollback

  • Restore the last booting EFI folder.
  • Use the officially supported macOS installer to recover the machine.
  • Do not erase the internal disk until the installer can boot twice consistently.

Original Question: "Adobe photoshop crash iMac late 2015 Sequoia 15.1.1 OCLP 2.1.2"

Hello,

After updating to Sequoia 15.1.1 or OCLP 2.1.2 my Adobe photoshop crashes when I start it. I read somewhere about the adding the AMFIPass.kext and changing one boot arg to fix adobe crashes on systems that runs with OCLP! Before 15.1.1 or OCLP 2.1.2 it was working fine.. latest Lightroom classic runs without a problem. Has anyone same issue and is there a fix for it? Tnx
