You can install sshfs via brew, but it works a lot better if you just download the package manually. That being said, I wouldn't recommend using sshfs on Mac.

You can install sshfs via brew, but it works a lot better if you just download the package manually. That being said, I wouldn't recommend using sshfs on Mac. I used it for about a year, and about 90% of the time it worked great. The rest of the time it would hang, just not sync, not let me write files, etc. and every couple of weeks it would break so badly that a restart was the only fix, usually at the most inopportune times. I ended up just grabbing an old external hard drive and installing syncthing. The remote server still has all the RAID and backups and whatnot, but now I basically have a local cache on the old hard drive, so it works consistently and is fast. If it breaks, oh well, I'll get another one and sync it again.
