How to Fix Error "[EB.H.IS|!]" / "[EB|LOG:EXITBS:START]" occurs whenever I attempt to install MacOS 11-MacOS 14, but not on MacOS 10.15 or older on macOS

Wi-Fi, Bluetooth, AWDL, Continuity and Location Services problems usually come from chipset support, kext pairing, privacy settings or network-location corruption. On Hackintosh systems, Location Services and Continuity depend on working Wi-Fi, Bluetooth, AWDL and correct AirportItlwm or itlwm/HeliPort behaviour.

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. Confirm the exact chipset: Identify the Wi-Fi, Bluetooth and Ethernet controller from System Information, Hackintool or Linux/Windows device manager.
  3. Use the correct network stack: Match AirportItlwm, itlwm, HeliPort, IntelBluetoothFirmware and BlueToolFixup to the exact macOS version.
  4. Reset macOS network state: Remove the current Wi-Fi service, reboot, add it again, then reconnect to a simple WPA2 network before testing advanced features.
  5. Check privacy permissions: Open System Settings and confirm Location Services, Maps, Weather and system services are enabled.
  6. Test Apple features separately: Verify normal internet first, then Bluetooth, then AirDrop/Continuity. Do not debug all three at the same time.

Do Not Continue If

  • Do not continue if: you do not have a working EFI backup, a Time Machine backup, or another bootable macOS installer.
  • Stop and capture evidence: if the machine stops booting, take a photo of the last verbose line before changing more settings.

Verify It Worked

  • Maps can locate you without falling back to a stale location.
  • Wi-Fi reconnects after reboot and sleep.
  • Bluetooth remains available after a cold boot.
  • Console no longer shows repeated wireless or location daemon errors.

Rollback

  • Restore the previous EFI if Wi-Fi disappears completely.
  • Switch from AirportItlwm to itlwm + HeliPort, or the reverse, if the issue is specific to one driver path.
  • Use Ethernet or USB tethering while testing so you do not lose access to downloads.

Next Action

  • Test now: reboot twice, reproduce the original problem, and confirm whether the same symptom returns.
  • If it still fails: record the Mac model, macOS build, OpenCore or OCLP version, GPU, Wi-Fi/Bluetooth chipset, and the last visible error.
  • Read next: use the related searches below for the nearest OpenCore or OCLP fix before making another change.

Original Question: "Error "[EB.H.IS|!]" / "[EB|LOG:EXITBS:START]" occurs whenever I attempt to install MacOS 11-MacOS 14, but not on MacOS 10.15 or older."

Hello. I have successfully installed MacOS Catalina 10.15.7 Onto my Dell Latitude 5400 Laptop. I have gotten everything working and my install is 100% successful, BUT, Catalina is quite old now, and I really want MacOS 11+, Since it adopted a new look, which is much more pleasing to look at.

When I try to install MacOS 11 to MacOS 14 natively from Catalina, and if I try the recovery method, it always gives me the EXACT same error codes. People have installed MacOS Ventura (13) on this exact laptop model before, but even if I try copy their EFI and make ajustments accordingly based off my hardware, it always spits out the same error code in the log.txt, and onscreen in verbose mode, it gives "Kernel Panic."

Does anyone know what is wrong? How can I fix this?

Specs:

  • CPU: Intel i5-8365U (Whiskey Lake-U Gen CPU)
  • RAM: 16GB 2400MHz
  • iGPU: Intel UHD 620 (Whiskey Lake refresh)
  • SSD: WD_Black sn750 NVMe
  • Ethernet: Intel I219-LM
  • WLAN: Intel Wireless-AC 9540 160MHz + Bluetooth 5.0
  • Sound Card: Realtek AC236

Also please note that this error code happens even if I make an EFI complimentary for that MacOS version, so no its not the fact it's a Catalina EFI causing the error.
