The Mac EFI Toolkit is a handy software that aids in collecting information and carrying out basic editing tasks. It has the ability to detect an EFI lock in the NVRAM, identify the APFS DXE driver, even in an LZMA compressed volume, verify file sizes, and calculate size discrepancies in bytes. Moreover, it can display the firmware version, making it a versatile and useful resource for Mac users.

Mac EFI Toolkit is an efficient solution that enables users to replace their System Serial Number (SSN) with an automatic Hardware Configuration (HWC) match and CRC32 mask. This toolkit also supports the transplantation of exported Fsys stores with automatic CRC32 masking, which enhances its functionality. Moreover, in case a customer forgets their password, Mac EFI Toolkit can clear firmware settings and EFI password lock to ensure that the customer can regain access to their device without any hassle.

Overall, Mac EFI Toolkit is a reliable and user-friendly tool that simplifies firmware management for Mac users.
