I am running macOS High Sierra 10.13.6. When I look for /etc/fstab file, I found /etc/fstab.hd file (no /etc/fstab file was present), and the file content says IGNORE THIS FILE.

But when I google, there are many articles still talking about /etc/fstab such as this link. So should I create and use /etc/fstab file? If it's not recommended, what is the recommended config file then?


afaik, fstab doesn't exist by default. You have to create one, first time.

From your linked instructions...

7) Edit (or create) an fstab file by typing the following and pressing enter:
sudo vifs

Will do precisely that, edit - or create - an fstab file.
Once you've got it set up, it ought to work as expected. I have mine set with ACLs so it will let me edit it without jumping through hoops every time. iirc, by default it's set to root/wheel.

fstab.hd seems to be a red herring, but no amount of Googling has turned up what it is or was used for :/

  • thanks a lot for the answer. so does it mean /etc/fstab is safe to be used in macos? I am just afraid it's not a recommended way. – sgon00 Aug 4 '18 at 6:45
  • It's absolutely fine, once you've got it set up. – Tetsujin Aug 4 '18 at 6:50
  • Curious... what do you think you need to use it for? – Marc Wilson Aug 5 '18 at 19:52
  • I use it so clones, boot camp & spare drives don't auto-mount at boot. – Tetsujin Aug 6 '18 at 6:23

    How do you specify a mount point containing spaces? I want to mount a separate drive to /Users/davec/Music/iTunes/iTunes Media/Music and have failed with all three methods, soft quotes, hard quotes, and escapes. – tgunr Apr 4 '19 at 2:09
