Bluetooth not working after changing SMBIOS #13

Bluetooth is normal before adding the serial number. Bluetooth cannot be turned on after adding the serial number. My CPU is I7-8665U, which has this problem in Sonoma and Ventura. 截屏2023-12-17 03 09 05

And there is an error in the memory, I can't open about this machine. After manually adding the memory information in OCC, about this machine can be opened normally, but OCC can't read the config, very strange...

PlatformInfo: Disable Custom Memory option (I've enabled it on my system because RAM speeds were reported wrong so I had to add custom entries which I deleted before uploading the EFI folder - but I forgot to disable the option)
Bluetooth: the kext only contains the firmware for the Intel AC-9560, so it doesn't work for other cards.
⚠️ Generate your own CPUFriendDataProvider kext if you havea different CPU!
Don't use OpenCore Configuratort!

My bluetooth is also AC9560.

First of all, thank you very much for the EFI you made, it's really great, but I have tried to reinstall the system many times after the Bluetooth problem happened, but this Bluetooth problem still exists, mainly after I add the serial number. Once I add the serial number, the Bluetooth will not work. It is normal until I add the serial number.

Read the Instructions:

Platforminfo/Generic: Generate an MLB, Serial and ROM for MacBookPro15,2 with GenSMBIOS or OCAT. ⚠️ Don't change the SMBIOS or the USBMap.kext won't work anymore!

This is my first time trying black apple. Thank you very much for your generosity in sharing your efi, and thank you for your patience in answering my ignorant questions.

In EFI/OC kexts, find USBMap_MBP152.kext and do the following:

Right-click it
Select "Show Package Contents"
Open info.plist with ProperTree
Change model to MacBookPro16,3 as shown below
