Like the question states, Can you use a Pegasus3 volume to store a user's home directory in Mac OS? Assume the latest version of Mac OS, and new Thunderbolt 3 enabled Mac.

Rather than use the default internal storage for the user's home directory, can I create a user that is configured to have their home directory stored entirely on the Pegasus3?

I know how to configure the user's home directory to a different disk, I want to know if this is a supported functionality of the Pegasus3.

Thanks.

Hi Alex,

Has there been any testing with this functionality conducted by Promise? I'd like to have a better warm and fuzzy that it would work before investing $1500 in something that might not meet my requirements.

This had not been tested by Promise. It's not a storage question at this point, it's a macOS question, so the Apple forums would be a better place to make inquiries.

I'll share one suggestion that I did follow when I setup my current Mac to host a couple of profiles on a second drive. I kept one user profile located on the OS volume. In the even the second drive failed, I should still be able to boot and log into that account.

Yes, this is a caution I've seen several times, make sure you have an admin account on the boot disk in case anything goes wrong, it's a very good idea.

Thanks for the reply.

WIth the limited disk space that is offered by Macs these days an external drive is almost a must.

The Pegasus is block level storage and the Pegasus knows nothing of your operating system or files. So this is a matter of whether macOS supports moving the home folder or not.

One thing to note, external storage does not come onlne till late in the boot process, unlike internal disks. So this may be a complication. Many people have asked this question about using an external disk as the home folder, and they have had various degrees of success.

A common suggestion in these posts is to backup your data first.
