Remove unnecessary WiFi firmware files
This steps help you to speed-up a little the boot process (if you use `itlwm` or `AirportItlwm`)
  1. Clone the repo: git clone https://github.com/OpenIntelWireless/itlwm.git
  2. Open the folder where it's cloned to
  3. Open Xcode, press File -New -File.. on the Search bar/Filter type shell and choose to create a new shell script file
  4. Copy this code below into it;
#!/bin/bash

# remove all local changes
git reset --hard HEAD
rm -rf build

# pull latest code
git pull

# remove generated firmware
rm include/FwBinary.cpp

# remove firmware for other wifi cards - DELETE OR CHANGE TO YOUR CARD
find itlwm/firmware/ -type f ! -name 'iwm-7265-*' -delete


# generate firmware
xcodebuild -project itlwm.xcodeproj -target fw_gen -configuration Release -sdk macosx

# build the kexts
## 1. itlwm.kext
xcodebuild -project itlwm.xcodeproj -target itlwm -configuration Release -sdk macosx

## 2. AirportItlwm Mojave
xcodebuild -project itlwm.xcodeproj -target AirportItlwm-Mojave -configuration Release -sdk macosx

## 3. AirportItlwm Catalina
xcodebuild -project itlwm.xcodeproj -target AirportItlwm-Catalina -configuration Release -sdk macosx

## 4. AirportItlwm Big Sur
xcodebuild -project itlwm.xcodeproj -target AirportItlwm-Big\ Sur -configuration Release -sdk macosx

# Location of Kexts
echo "You kexts are in build/Release!!"
echo " "

  1. Change line 14: find itlwm/firmware/ -type f ! -name 'iwm-7265-*' -delete

    change iwm-7265 to your firmware name and save the file.

    If your card is AC8260 you need to replace find itlwm/firmware/ -type f ! -name 'iwm-7265-*' -delete by find itlwm/firmware/ -type f ! -name 'iwm-8000C*' -delete

    This part of code remove other firmware files from /itlwm/itlwm/firmware

    Also here you can find your card firmware name

  2. Place the file in the root directory of the cloned itlwm folder.

  3. Clone MacKernelSDK git clone https://github.com/acidanthera/MacKernelSDK.git and place it's folder inside itlwm folder

  4. Run the script with sh command. Ex: sh script-name.sh where 'script-name' is the name of the shell script you made.

Done, you'll find your kexts under build/Release

DON'T USE BOTH itlwm and airportitlwm IN THE SAME TIME.

Remove unnecessary Bluetooth firmware files
This steps help you to speed-up a little the boot process (if you use [IntelBluetoothFirmware](https://github.com/OpenIntelWireless/IntelBluetoothFirmware) kexts)
  1. Clone the repo: git clone https://github.com/OpenIntelWireless/IntelBluetoothFirmware.git
  2. Open the folder where it's cloned to
  3. Open Xcode, press File -New -File.. on the Search bar/Filter type shell and choose to create a new shell script file
  4. Copy this code below into it;
#!/bin/bash

# remove all local changes
git reset --hard HEAD
rm -rf build

# pull latest code
git pull

# remove generated firmware
rm IntelBluetoothFirmware/FwBinary.cpp

# remove firmware for other wifi cards - DELETE OR CHANGE TO YOUR CARD
find IntelBluetoothFirmware/fw/ -type f ! -name 'ibt-11-5*' -delete


# generate firmware
xcodebuild -project IntelBluetoothFirmware.xcodeproj -target fw_gen -configuration Release -sdk macosx

# build the kexts
## 1. IntelBluetoothFirmware.kext
xcodebuild -project IntelBluetoothFirmware.xcodeproj -target IntelBluetoothFirmware -configuration Release -sdk macosx

# build the kexts
## 2. IntelBluetoothInjector.kext
xcodebuild -project IntelBluetoothFirmware.xcodeproj -target IntelBluetoothInjector -configuration Release -sdk macosx

# Location of Kexts
echo "You kexts are in build/Release!!"
echo " "

  1. Change line 14: find IntelBluetoothFirmware/fw/ -type f ! -name 'ibt-11-5*' -delete

    change ibt-11-5* to your firmware name and save the file.

    If your card is AC8260 you no need to change this line

    This part of code remove other firmware files from IntelBluetoothFirmware/IntelBluetoothFirmware/fw/

    Also here you can find your bluetooth firmware name

  2. Place the file in the root directory of the cloned IntelBluetoothFirmware folder.

  3. Clone MacKernelSDK git clone https://github.com/acidanthera/MacKernelSDK.git and place it's folder inside itlwm folder

  4. Run the script with sh command. Ex: sh script-name.sh where 'script-name' is the name of the shell script you made.

Done, you'll find your kexts under build/Release

Thanks @racka98 for the idea.
