Ufs For Macos Sierra
Check compatibility
Mar 21, 2001 In the further text, when I talk about UFS, I am talking about 4.4BSD FFS, known as UFS in Darwin/Mac OS X. I am explicitly not refering to ext2 FS Linux users may be familiar with. Regarding UFS fragmentation, there is a lot of misunderstanding concerning the fragmentation percentage reported by fsck. Recover deleted files from the file systems of macOS. At present, macOS applies three types of file systems: HFS+ is used in macOS up to 10.12 Sierra, APFS – in macOS 10.13 High Sierra and later while FAT/exFAT can be found on portable devices.
You can upgrade to macOS Sierra from OS X Lion or later on any of the following Mac models. Your Mac also needs at least 2GB of memory and 8.8GB of available storage space.

I do not want to reformat my macbook, but it would be great if there is a chance to directly
mount my external harddrives. Unfortunately a mount_ufs or mount_ffs command does
not seem to be available. Maybe as an optional package?
Right now, the only way to access my external drives are to plug them into the BSD box,
export via NFS and then mount per NFS on the macbook. It works, but the data has to go over
the network and the BSD box must be running, obviously not the most efficient way..
Many thanks,
Daniel
Macbook, Mac OS X (10.5.3), external drive uses FreeBSD's UFS2, and is used by FBSD 7.0 boxen.
