How to Fix Dell Latitude 5490 is failing to install the MacOS 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.
