I. Introduction

1. U-BOS2 is an essential tool for repairs of iMac, Mac Mini, MacBook Pro, and MacBook Air.
2. It features a convenient LED color screen for easy display operations.
3. It supports Type-C and Micro USB cables for power supply and can also be powered by regular AAA batteries.
4. U-BOS2 includes a main unit, four writing sockets, one universal board, and one USB flash drive for adding serial number.
5. The U-BOS2 main unit contains SPI ROM data for over 100 models of Mac series
 

II. Usage

1. It can resolve issues such as MacBook motherboard failure not powering on, no display, freezing, and blue screen caused by BIOS data problems.
2. It can be used to remove EFI locks, MDM lock, and PIN code locks on 2008-2017 MacBooks.
3. It can write original data of T2 or M1 chip ROMs for 2018-2020 models (to determine if the no power issue is caused by ROM data).
4. It can modify the internal ME (Management Engine) data in BIOS for MacBook models from 2013-2017. If the CPU, PCH, or BIOS chip has been replaced and the ME data is not updated, the startup will be slow.
