Editing for Web: PC vs Mac Gamma

I'm in a debate, I go to photojournalism school, it's a mac industry, I do a lot of web stuff, it's a PC industry...and the gammas between the two are very different when toning my photographs.

I finally got the computers at school setup for better toning for the web, took me long enough to learn how to do it...

but is there a way to get a medium between the two gammas and be satisfied with my images? this is the debate I have been having the last two days, my stuff usually either looks good on one and crap on the other, or just flat in both...

a prime example is today:

default settings here in the digital imaging lab, mac displays

vs

my settings, toned more closely for correct rendering on the apple gamma from the web
http://blinking8s.com …G_2167_edit22_c​orrect.jpg

the 1st is very flat on the apple displays, and ok on a PC i think, still not right, the 2nd is almost spot on to what I was after published on the web with the apple display, and dark on the PC gamma...

any tips or advise to deal with this?

Most macusers use PC gamma nowadays, I think. Mac gamma setting is an old setting. Maybe some other macuser will refute what I'm saying, but I don't like the mac gamma setting.

Computers at schools are notorious for not being calibrated, FYI...

Use gamma 2.2 for both mac and PC. It will only affect non color managed applications anyhow, and on a mac you can even browse the web colormanaged (Safari).
By the way, in Safari, on my screen, the original looks better then 'your' version: There the darker parts (Right girls face) are too dark IMO.
How do you have your PSCS color settings set? Gamma settings should *not* influence how you see things in PS.
