    I'm having some issues trying to understand my activity monitor on my macbook. It's actually technically a shared computer (although I use it 99% of the time), with about 4 different users who barely ever log on. It's for work, so I'm in an office building and using a cable for my internet. In the past two days, there have been two incidents where one of the user's names (who is rarely here and hasn't been on the computer in months), appeared on the activity monitor for about two minutes and then mysteriously disappeared. Any ideas? Why is this happening? He is definitely not logged in. Also there has been a message that another device on my network was using my IP address, but I figured that had to do with the fact that I am in an office building. Please advise! What's going on?

    It's probably just a background processes for that user's account.

    Just because a user is not logged in does not mean that processes associated with an account cannot run.

    What do you mean, "what is going on" ? That particular error message is not ambiguous. There are duplicate IP addresses on the network segment. This could happen if you are using static IPs and literally typed the same address into two machines. It could also happen if the DHCP server has run out of addresses and has assigned the same one twice (although this is unlikely), or it could be that your DHCP lease is set to a lengthy expiration time and you connected/reconnected to the network before that address was returned to the pool of available addresses.

    Can you give an example of this?
