MacOS Uptime Command – Why Two Users Show in Results

macmacosuptimeusers

When I ran the uptime on my MacBookPro machine I got the following result:

Last login: Thu Jun  3 14:43:40 on ttys000
Osama-Gamal-MBP-2:~ iOsama$ uptime
14:49  up 7 days, 20:10, 2 users, load averages: 0.29 0.24 0.24

Why it lists that there are two users? is it normal? and who is the other user, is it the root user or what?

PS: I'm using Mac OS X 10.6.3
Edit: w command output:

Osama-Gamal-MBP-2:~ iOsama$ w
 0:41  up 8 days,  6:03, 2 users, load averages: 1.92 1.81 1.38
USER     TTY      FROM              LOGIN@  IDLE WHAT
iOsama   console  -                26May10 8days -
iOsama   s000     -                 0:13       - w

who command output:

Osama-Gamal-MBP-2:~ iOsama$ who
iOsama   console  May 26 18:40 
iOsama   ttys000  Jun  4 00:13

Try the w command. On my system I have the following:

# w
 02:16:53 up  6:48,  2 users,  load average: 0.50, 0.42, 0.52
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT
pcm      tty7     :0               19:28    6:48m 16:07   0.17s gnome-session
pcm      pts/0    :0.0             01:51    0.00s  0.36s  0.76s gnome-terminal
# uptime
 02:16:56 up  6:48,  2 users,  load average: 0.50, 0.42, 0.52

tty7 is your desktop login, pts/0 is a pseudo terminal ... probably what was used to type uptime in.

Why it lists that there are two users?

Because it shows every logged in session. A single user can have multiple active sessions at any one time.

is it normal?

100% normal ... A-OK

and who is the other user, is it the root user or what?

The other user is yourself. You have multiple sessions running. You can see in your output from your question, that the user name is the same for both sessions.
