To obtain the necessary information, you must hold SHIFT + CONTROL + OPTION + COMMAND + S on the firmware password prompt screen and a string will be generated. How are the SCBO files generated?Īs previously mentioned, Apple support is able to generate these files after you provide some key information. The rest of the string and binary data that follows are unknown for now. This information can be verified because part of this string can be found in the motherboard of each Mac (my sample is only composed of MacBooks but I guess iMacs and others will contain the same information).

It appears to be some kind of serial number. A couple of bytes later and we see another string. The ‘SCBO’ string is clearly visible in the first four bytes, which is a magic number (0x4F424353).

This picture shows us the full contents of the sample file. So let’s start another EFI reversing engineering adventure…Īt the time I could only find a single SCBO file on the Internet, which is bad (impossible to visualise differences between files) but better than no file at all. Understanding how SCBO files work in the first place was also intriguing. If this were true, it would imply that Apple’s EFI contains a significant vulnerability. The core question I wanted to answer was if it was really possible for someone to build a SCBO file key generator. Upon my return from SyScan360 Singapore, I needed a new research di‐ rection to kickstart my brain back into work, and this fit the bill. Since there was (still holds true) virtually no information about the SCBO contents, this aroused my curiosity but I never followed up until now. There are videos (in Portuguese but you can watch the whole process) of people claiming this works, and even some claims about an universal SCBO that unlocks multiple Macs. Things got more interesting when I found a website that allegedly sold the SCBO files – just send them the necessary hash (more on this later), pay USD100, and get a working SCBO file in return. Since I don’t have the original sales receipt of this specific Mac, I assume this option isn’t possible, since anyone with a stolen Mac could get the password reset. The normal process workflow is to first contact Apple support. My preliminary research found references to a “magical” SCBO file that could be loaded onto a USB flash drive and booted to remove the password.
Type diskpart into the Command Prompt window and press Enter.My original goal when I started poking around Apple’s EFI implementation was to find a way to reset a Mac‐ Book’s firmware password.

To do this on Windows 8 or Windows 7, press the Windows key once, type cmd, and press Ctrl+Shift+Enter. Next, open a Command Prompt window as administrator. For example, in the screenshot below, the Mac-formatted drive is Disk 2. First, note the number of the disk in the disk management window. This process erases everything on the disk, including its files and all its partitions. To erase this partition, we’ll have to wipe the entire disk. This partition is marked as protected, so you can’t just right-click and delete it - the delete option will be disabled.
The Mac drive may have an “EFI System Partition” on it. You can then right-click in the empty space and select New Simple Volume to create a partition and format it with the Windows NTFS or FAT32 file systems. If you’re lucky, you can just right-click each partition on the Mac drive and select Delete Volume to remove the partitions. Be sure you’ve identified the Mac drive - if you accidentally delete partitions from another drive, you could damage your Windows installation or lose your files. Locate the Mac drive in the list of disks. This tool allows you to manage the partitions on drives connected to your computer - internal ones or external ones connected via USB. Press Windows Key + R to open the Run dialog, type diskmgmt.msc into the box, and press Enter to open it.

HFSExplorer unfortunately requires you install Java to use it, but it’s the only free option here. If you only have Windows systems available, you can use HFSExplorer to copy files from the drive onto your Windows system drive or another drive. If you have a Mac lying around, you can plug the drive into a Mac and back up the files. Instead, we’ll just be wiping the drive and starting over from scratch. This process won’t actually convert the file system. First, back up the data on the Mac-formatted drive if you have anything important on it.
