Don’t blindly follow AI instructions

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.

Clean up stale mount points: Sometimes, stale mount points can cause issues. You can try to remove them by running the following command in Terminal:

sudo rm -rf /Volumes/*

Then restart your Mac and attempt to mount the shares again.

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.
