Ask Different is a question and answer site for power users of Apple hardware and software. It's 100% free, no registration required.

There used to be the ability, perhaps before OS X, to send messages accross the local network, which displayed a popup on the receivers machine with the message. Is this still possible? Or is there another way to send a message to another member of the network?

If this isn't possible, could a text file be sent, with a message, to a recipients Public folder?

Preferably with the terminal.

(I realise there are lots of aps which do messaging, but I was curious if this was possible without installing software or setting up iChat etc)

Just to be sure, you want to send a message from a Mac to another Mac? Or is there a Windows computer involved? Could you also add which OS versions your machines are using? –  Bart Arondson Feb 18 '13 at 21:23

According to this metafilter post you can send a message using Applescript (pre-installed on every Mac) and Growl (old version is freely available). The relevant part is quoted hereunder.

tell application "GrowlHelperApp" of machine "eppc://xxx.xxx.xxx.xxx"
register as application "myapp" all notifications {"message"} default notifications {"message"}
notify with name "message" title "title"   description "description" application name "myapp"
end tell     

Here xxx.xxx.xxx.xxx should be substituted by the IP address of the sender.

That's interesting, but its a third-party program. Is there something which would work with a base OS X install? –  wildebeesty Feb 19 '13 at 12:01
