How to Fix Problem with Late 2011 MacBook Pro 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
- 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.
- Confirm the exact chipset: Identify the Wi-Fi, Bluetooth and Ethernet controller from System Information, Hackintool or Linux/Windows device manager.
- Use the correct network stack: Match AirportItlwm, itlwm, HeliPort, IntelBluetoothFirmware and BlueToolFixup to the exact macOS version.
- 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.
- Check privacy permissions: Open System Settings and confirm Location Services, Maps, Weather and system services are enabled.
- 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: "Problem with Late 2011 MacBook Pro"
Not sure if this is the right sub but i'll ask anyway, hopefully anyone can help me.
So I found 2 MacBook Pros from my workplace and the manager said I can keep them. They're a Mid-2012 13 inch and a late 2011 13 inch. I wanted to move my SSD and RAM to the 2011 because the 2012 only has the left tinny sounding speaker working and I was going to sell the 2012 instead. The 2011 is in better physical shape, I didn't mind about the slightly lower specs as I already have a Main Computer i use daily. But when i put the SSD in 2011, it refuses to upgrade to High Sierra, while I create a bootable usb the whole system crashes, try internet recovery, gets stuck while updating, tried a bootable usb it says failed firmware update, with the HDD it worked fine. The only way I was able to get High Sierra was to download it on 2012 MacBook and then put the SSD in the 2011 and then it worked, but when I tried using OpenCore legacy patcher, everything worked but creating the USB Install the whole system froze again. Does anyone know what the issue is? Is the SSD Incompatible?
Edit: Forgot to mention I did swap the SATA cable between 2011 and 2012 and the 2011 the problem still persisted
