Yes, you can re-enable it later with вЂcsrutil enableвЂ™. To disable it, reboot into Recovery mode, open the Terminal and type вЂcsrutil disableвЂ™ and restart the system. While not technically good for security purposes, it can be a general pain in the posterior to have on. SIP is now protecting /dev and will likely make forensic acquisition and analysis more difficult if you happen to interact with /dev often. Anyone who has tried to capture their disk images in 10.13 might have had a problem doing so due to System Integrity Protection (SIP). Gotta love hidden functionality! This will output a bunch of /dev/disk* options, however none of these are the ones you need thanks to CoreStorage.ДЄ similar approach can be used for new APFS disk images. It is also is not detailed in the hdiutil man page. It is worth noting here that while hidden in 10.13 this option does not appear to exist in 10.12 versions of this utility. Using the hidden argument вЂ“blocksize we can specify 4096 (вЂ4kвЂ™ can also be used here). Using hdiutil, attach (but donвЂ™t yet mount) the DMG file created in Step 3. Having trouble installing Xmount? Does it say OS X Fuse is not installed? Look in the comments section for a fix.Д¤. Theoretically you can use another mounting utility, I've tried ewfmount on 10.13 and ran into errors that I'm still investigating. This could take a few seconds if the disk image is large. Provide the E01 image (use E? if using segments) and the converted image mount point created in Step 1. DMG is selected here since it is very Mac friendly. Using xmount (sudo required) to convert from EWF (-in) to DMG (-out) format. This will act as the root volume for the mounted image.ДЈ.

Create another mount point to put the mounted image on. Create a mount point to put the xmount converted DMG image (converted from EWF format). $ sudo mount_hfs вЂ“o rdonly,noexec,noowners /dev/disk# /Volumes/4k_mounted/ДЎ.

$ hdiutil attach вЂ“nomount вЂ“blocksize 4096 /Volumes/4k_image/4k.dmg $ sudo xmount -in ewf -out dmg 4k.E01 /Volumes/4k_image/ (If you have a raw (non-EWF) image, you can bypass steps 1 and 3.)

The following steps will bring you from a full HFS+ FileVault 4k disk image in EWF format to a mounted image using macOS 10.13.

This article will try to provide some options to mount these images, however it cannot solve all the issues or combinations of disks/block sizes/host operating systems вЂ“ it seems that you will have to upgrade to 10.13 at some point to solve many of these problems.

If you see otherwise, please let me know!

I will also detail how to mount the forensic disk images using newer APFS file system so analysts can start to do their thing while all the forensic tools catch up! APFS disk images already appear to use 4k block sizes as the default, at least on all my test systems. BlackBag wrote a good blog article on this last month however I hope to expand on it just a bit to include E01 files and FileVault encryption scenarios. This has caused some issues where you need to mount the image to do analysis without a major forensic suite. A few years ago, Mac systems started to use 4k blocks instead of 512 byte block sizes. Recently there has been some questions on the forums and Twitter as to how to mount forensic disk images that were captured from Mac system that implemented 4k block sizes.
