Saturday Mac riddles 68

Here are this weekend’s riddles to entertain you through whatever you’re now allowed to do.

1: Factory closure, pull the plug, or your command when all is done.

2: I came before your calendar, live on as an extension, and extend into a standard. What was I?

3: Found between rooms, in Ireland, and in storage.

I will post the answers first thing on Monday morning.

Please don’t post your answers as comments here: it spoils it for others.
