[Alt-photo] Separating channels

Hi everyone,

The only thing I use my elderly Photoshop CS for is to separate channels for
tricolour gum (and soon, I hope, casein!). It's not worth hundreds of pounds
for me to update to a new version of PS to run on my iMac just for that one
task. But to use CS, I have to maintain a separate bootable Snow Leopard
disc, which seems a lot of trouble for one job.

Can anyone point me to a mac-friendly application that will separate
channels, preferably cheap or free?

Many thanks
