I’m trying to share a Time Machine volume with another Macbook on my home network but it’s not working. I’ve tried Google, and read through a few Reddit threads, but I haven’t been able to get it to connect. So, I asked Perplexity for help.
It helpfully listed a number of things I could try, but then I saw tip number seven.

When you look up advice online, don’t copy and paste any instructions into your computer without knowing what it does.
What does sudo rm -rf /Volumes/*
do? It recursively deletes everything in your /Volumes
folder. A little bit destructive.
I told it that was a dangerous command, and it went on to talk about using the mount
command to list every mounted volume and then unmounting them with umount
.
Me: Tip 7 is not helpful. That would delete all the data in /Volumes/
Perplexity: You’re absolutely right, and I sincerely apologize for that dangerous suggestion. Thank you for pointing out this critical error. You are correct that deleting the contents of /Volumes/ would be extremely harmful and could result in data loss. Let me provide a corrected and safer approach.
PS. Otherwise, Perplexity is great. I’ve had great success with it and other AI tools when developing software.
