Can I start tightvncserver to show the same screen on hdmi screen and vncclient?

I tried -alwaysshared, but could see no difference.

Edit I want to remotely control Pi, using keyboard, mouse on remote (Mac), and have display on Pi hdmi screen as well as remote. I used to do this in the distant past, running Linux from a Windows PC. Further research indicates tightvncserver can't do this (so what does -alwaysshared do?). I also tried x11vnc, but can't get this to do anything on the Mac.

You should install x11vnc and configure it to get same screen on HDMI and also vnc client. 

apt-get install x11vnc

then run x11vnc command with parameters.

x11vnc -display :0 -usepw -listen IP_of_pi -allow allowed_ip_address

-display : screen number to get
-usepw   : use password security
-listen  : IP address of server (Pi IP)
-allow   : allowed client IPs (client IP, in your case Mac IP address)

Then use a VNC client on your Mac, i prefer 'Chicken of VNC' and connect to Pi IP address.

Update:
To tune VNC connection for performance you can use those parameters.

-noxdamage -ncache 10 -ncache_cr

You can find more parameters and definitions of x11vnc at http://www.karlrunge.com/x11vnc/x11vnc_opts.html
