![]() For recovery purposes, change the location in /etc/passwd. On macOS you can change the location of the root user's home directory. You usually don't want it in /home or /Users as that could be a networked file system, and you traditionally wanted the root user to be able to always be able to login for system recovery. In this sense the root user's home folders fits the description. It means that the contents of the folder might change while using your system - in contrast to for example /bin, where traditionally you could assume that this folder could just be reinstalled from the original installation medium. Usually you would say that the /var folder is for variable data - however that doesn't mean that it is limited to spool or log files, like you write. This might vary from operating system to operating system. Regarding your assumption on the use of the /var folder: Traditionally there hasn't been any kind of hard consensus on what each of the traditional system folders are used for (for example /etc, /usr, /usr/local, /lib, /etc.). For example on HP-UX systems you wouldn't blink an eye to find the home directory at /homeroot. There's plenty examples of Unix-like operating systems that use varying locations. If you have worked with Linux or perhaps FreeBSD, you would expect the root user's home directory to be at /root - but it's not really "God-given". Traditionally with Unix-like operating systems, you would actually have the root user's home directory at /.

Note that APFS encrypted volumes are completely unusable in Sierra 10.12.6 unencrypted volumes work much of the time, with only occasional errors and problems. ![]() Using the case-sensitive version is likely to cause many issues. ![]() Unless you know exactly what you are doing, you should only use the APFS or APFS (Encrypted) options. You can then add additional volumes, if required, by selecting the drive at the left and using the Volume tool above the list of drives. If you experience difficulty getting Disk Utility (High Sierra) to format a disk in APFS, select the drive at the left, then click on the Partition tool above, and select the APFS option if offered. Avoid if possible, using HFS+ or iCloud Drive as an intermediate store. under Sierra – unsupported and prone to error and problems.under High Sierra – fully supported and appears reliable.Problems were experienced during beta testing, so do not try. Home-brew ‘fusion drives’ could be defused into separate SSD and hard disks, then the SSD formatted in APFS, if you wish.Ĭannot currently be converted to APFS.Cannot currently be converted to APFS.Behaviour appears inconsistent, and can also result in errors when formatting or in use.įusion Drives (combined SSD and hard disk, united in CoreStorage): Others can be, at least in Disk Utility, but this must be performed using the Partition tool, not Erase. Disk Utility (High Sierra) either does not offer the option, or returns an error when attempted. Some cannot be converted to, or formatted in, APFS. If you want to convert it to APFS, you must defuse it by uninstalling CoreStorage and turning the SSDs back into separate drives again. CoreStorage – if an SSD is part of a CoreStorage ‘fusion’ drive, even if the other drives are also SSDs, then it will be left in HFS+ and cannot be formatted as APFS.When High Sierra is installed on them from High Sierra, though, it will install onto APFS if so formatted, but does not automatically convert. External – not converted when High Sierra is installed on them from Sierra, no option, and installer will not install from Sierra onto APFS, only HFS+ Journaled.Can be converted from HFS+ Journaled to APFS, and formatted as APFS, using Disk Utility in High Sierra.
