Hi,
I don't know if this has been asked before as I don't seem to be able to search the archives. I'm in the process of moving jobs which will involve frequent relocating. I'm considering investing in a decent portable setup for doing some image post processing. I mainly use macs these days but I use a windows box and adobe lightroom. I plan to move to a high end 15" macbook pro. Any recommendation of post processing software that runs well on a mac? And this might be stretching things but are there any recommendations of software that will run on a high end(read as maxed out) macbook air just in case I want to go even more portable?

Thanks in advance.
