How to Fix open core legacy patcher on 13" MacBook Pro 2010 WiFi Issue 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: "open core legacy patcher on 13" MacBook Pro 2010 WiFi Issue"
Below is my experience so far.
I installed Monterey on my MacBook Pro 2010 13" 7,1. After installation and a few scary moments I managed to get it installed and working "mostly".
For instance: During the installation my computer seemed to be stuck at the "Less than 1 minute remaining" for such a long time I thought the installation failed or was about to fail. After doing a Google search I saw a posting saying that there is a ton of encryption going on at the end and that being patient is key. It also mentioned that pressing the caps lock key should show green if the computer is functioning normally and still installing. And this was the case, it eventually installed and booted.
2nd issue. Computer rebooted over and over again. Apparently this is normal. Eventually the computer will boot normally and stay that way. At least this was my case.
3rd issue. My Wifi card "looked" like its working but doesn't show any available wifi networks. One suggested work-around was to manually put in your wifi credentials. However, this did not work for me. After checking on the open core site I saw that my WiFi card (Wi-Fi (0x14E4, 0x8D) (Broadcom BCM43xx 1.0) is not supported. I considered ordering a wifi dongle from Amazon. However I could't find one that is compatible with my Macbook with Monterey installed. Or at least I could't find a definite answer. See below for a work around.
4th issue. After some minor use I notice my computer was getting very hot and the CPU seems to be pegging 100% for long periods at a time. Activity Monitor is showing WindowServer is taking a lot of CPU cycles when normally they would or should be low. See below for a work around.
5th issue. Spotlight was also hogging CPU cycles. But eventually it calmed down and is ok now. But for quite a while it wasn't. I thought there was a serious issue. So if this happens to you It might go away eventually. Apparently its building up a database so your Spotlight searches will be faster and more robust.
Fixes and work arounds.
For the Wifi. I noticed I could get Wifi working if I opened "About This Mac" then went to "System Report", then under "Network" I clicked on my Wifi cards properties. Then I would see all available networks in the properties under "Status". Then when I go back to my Wifi setting on the top Menu Bar all the familiar networks that I could pick from showed up. I bet someone could run with this information and make a simple fix.
For the WindowServer issue I read somewhere that they could be calmed down a little if you "reduce transparency" in the Accessibility setting under "Display". And after doing that it really reduced the CPU cycles. Mind you, If you watch Youtube or do many graphically challenging tasks the Computer will get hot again. Sometimes just using Safari with lots of moving graphics I notice the computer gets hot and the fans come on. But Oh well.
