Catalina does not have the AirportBrcm4331.kext in the IO80211Family.kext plugins. You can add the Mojave version to the Catalina plugin. Dosdude1's patcher can do this for you. Alternatively upgrade the hardware to a BCM94360CD as this works OOB with Catalina. Many have done this and it has the benefit of giving you all the handoff/continuity features. A thought for @cdf - can the AirportBrcm4331.kext be added to the Kernel part of OC to do this for members who wish to keep the old wifi card working in Catalina?

What problems are you having with the optical drive. Mine works fine.

Hi Flacko,

Thanks for your reply! Never mind about the optical drive 🙈, I just did not look for it in the right way. .

Do you have any suggestions for the names underneath the icons in the bootpicker screen?

Update, it works! I now have the boot switcher and it’s not being taken over by GRUB after a normal install with OC and Manjaro on same EFI partition. Thanks for the help @cdf @startergo

Nice! Some questions, if you don't mind: Did you use BlessOverride to point to GRUB? If not, did you check the contents of the EFI partition to make sure that OpenCore's bootx64.efi is still there (if you open the file with TextEdit, you should see "Acidanthera Research")?

Yes, adding the kext with OpenCore should work.

As mentioned in the OpenCore manual, there are a few options. OpenCore should respect the names assigned to the drives in Finder. Verify .disk_label.contentDetails in \System\Library\CoreServices.
 
Thank you all for the amazing information. i have a perfect opencore 0.5.9 installation and also windows 10, it runs perfect.

the only thing that is not working on catalina, is the original wifi card. i read in another post that this is the kext (mojave) i need the make it work: /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortBrcm4331.kext.


how can i install that kext without messing up my perfect mac?

Thanks so much!

ps. in my opinion, it would be a good idea to add this to the original WIKI, since the majority of people probably have the original wifi card.

I am no expert on this but it would be an elegant solution for those using OC to add the required driver as it has come up a few times. You could try this:

Copy the Mojave AirportBrcm4331.kext to /Volumes/EFI/EFI/OC/Kexts

Then edit the OC config.plist (back up first!) by adding something like this to the Kernel key under the Add key:



<dict>
<key>BundlePath</key>
<string>AirportBrcm4331.kext</string>
<key>Comment</key>
<string>Old WiFi Fix</string>
<key>Enabled</key>
<true/>
<key>ExecutablePath</key>
<string></string>
<key>MaxKernel</key>
<string></string>
<key>MinKernel</key>
<string>19.0.0</string>
<key>PlistPath</key>
<string>Contents/Info.plist</string>
</dict>

Cannot guarantee it would work so if there is an expert feel free to add/comment.

Copy AirPortBrcm4331.kext to the Kext folder in OpenCore and add the kext to your configuration with

Code: 
<dict>
<key>BundlePath</key>
<string>AirPortBrcm4331.kext</string>
<key>Comment</key>
<string>Legacy Wi-Fi</string>
<key>Enabled</key>
<true/>
<key>ExecutablePath</key>
<string>Contents/MacOS/AirPortBrcm4331</string>
<key>MaxKernel</key>
<string></string>
<key>MinKernel</key>
<string>19.0.0</string>
<key>PlistPath</key>
<string>Contents/Info.plist</string>
</dict>

See also the wiki for guidance on installing kexts. If this works, I can certainly mention it in the wiki.

(@Flacko, close but you forgot the executable path.)

Many thanks for your comment. Still trying to get familiar with this. Impressed so far with OC. Seems it has not worked though.

You can install the kext in /L/E:
Code: 
sudo spctl --master-disable
sudo mount -uw
sudo killall Finder
sudo cp -R AirPortBrcm4331.kext /Library/Extensions
sudo chown -v -R root:wheel /System/Library/Extensions
sudo touch /System/Library/Extensions
sudo chmod -v -R 755 /Library/Extensions
sudo chown -v -R root:wheel /Library/Extensions
sudo touch /Library/Extensions
sudo kextcache -i /

To verify that the kext is loaded after reboot, open up Terminal again and type:
Code: 
kextstat | grep -y "AirPortBrcm4331"

It should not break anything. All aftermarket apps install their kexts in /L/E. This is a signed by Apple kext so you should not even need to disable SIP for this.

Replace MojaveSSD with your Mojave drive label:

sudo cp -R /Volumes/MojaveSSD/System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortBrcm4331.kext /Library/Extensions

Use Hackintool under utilities-->install kext(s):

Then you can examine the log window.

Might be OOT, but…

WTF what is “OpenCore Computer?”
Anyone knows deeper? Is have relation with OpenCore bootloader we known? I was asked there but mostly they just folks who never getting touch with OC.

Just afraid it would threatening our favorite boot loader existence. I baffled since they sounds too same.

I tried this. All good until the end where it responded:

Exactly the same result using the Hackintool app linked above

Download dosdude's Catalina Patcher folder:
Inside is the patched AirPortBrcm4331.kext

Made the switch to OC, thanks to everyone who has worked so hard on this. Everything is working as expected after following the wiki.
My only lingering concern is the Windows SecureBoot issue...
Am I right in saying that all will be fine provided I never boot Windows outside of the OC boot picker?
The wiki doesn’t specify that other steps are necessary (others have deleted boot64.efi, for example)
I guess the question is “what is safest?”
Thanks

Delete the bootx64.efi and check it /delete after every Windows update.
