MacOS upgrade to Multipass 1.12: cannot connect to the multipass socket [solved?]

Multipass
#1

I updated to multipass 1.12, and I now get a “cannot connect to multipass socket” for any commands. I tried uninstalling/reinstalling with brew and package installer. I tried to set /var/run/multipass_socket with chmod a+w. Is there something I’m missing?

Solved: I happened to have a MacOS update to 13.4.1, and everything works now. I have no idea why. Maybe the socket file was rewritten.

Hi @asdf072 , I am glad MacOS upgrade solved that. About the error, it normally means that the server process multipassd was not present, so the client process multipass can not connect, the last 4th and 3rd line of the log indicated that the mutipassd launching failed. Why it failed on that version of MacOS is not clear to me though. Anyway, thanks for reporting this.

Hello! I’m having the same issue after following the instructions in “How to use multipass remotely | macOS”. I tried uninstalling/reinstalling both through the .pkg file and brew cask. After a clean install, I can see that Multipass works with no problems, but after following the instructions on how to expose the local instance to the network my multipass_socket file in /var/run disappears. Logs for reference:

Actually, it can met this error everytime when we switch different virtual machine hypervisor driver.
$ multipass set local.driver=qemu
$ multipass list
list failed: cannot connect to the multipass socket

There are some error log in /Library/Logs/Multipass/multipassd.log

Restart mac os can workaround it.

MacOS version Ventura 13.4.1
