# Simple Main Logic Board (MLB) Serial Generator Script by TheRacerMaster
# Based off the work of Hanger1, AGuyWhoIsBored & Alien:X
# NOTE: This is a simple script that doesn't do any checking of other SMBIOS values. It needs valid SMBIOS data which includes the following:
# - Valid SmUUID value in Clover config.plist under SMBIOS (generated using uuidgen)
# - ROM value set to UseMacAddr0 in Clover config.plist (uses MAC address of your first NIC as ROM value)
# - Properly formatted serial number (doesn't have to be a real one, just formatted properly) in Clover config.plist under SMBIOS
# - Don't use a generic serial number (such as Clover's default)! It needs to be at least semi-unique.
# - Try using a generated serial number that isn't real (but formatted correctly) from Clover Configurator, Chameleon Wizard, etc.
# - You can check if a serial number is real here: https://selfsolve.apple.com/agreementWarrantyDynamic.do
#
# After getting a value, insert it in Clover config.plist under RtVariables -> MLB, then reboot
# Try logging into iMessage. If you get a customer code, call Apple and go through the process.
# iMessage should work after going through the customer support process.
#
# Changelog:
# Version 1.1 - Add user input support; you can now input a serial number (as an argument: ./simpleMLB.sh XXXXXXXXXXXX) and the script will use that to generate a MLB
# Version 1.2 - Add more input checks for valid serial number and working internet connection; added support for generating 13 character MLB (does it if serial number is 11 characters)
# Version 1.3 - Fixed some bugs; removed internet connection requirement; now, the script gets week and year numbers from the serial number itself (more accurate than random generation)
# Version 1.4 - Added debug mode which prints info about the serial number and each step of the MLB generation process
# If user input is valid, use that instead of the serial number of the current machine from IORegistry

Shouldn't line 50 be 11 characters and line 52 be 12 characters?

Line 112 always fails for me as the regexp doesn't find the characters. This works for me: if [[ $(echo $SN | cut -c 4-5) =~ ^(-|[0-4])[0-9]|[5][0-3]+$ ]]; then
