Hi folks So I'm in that limbo period where I sold off my MBA (had an offer I couldn't refuse) and am waiting until June/July for the new rMBP models (if they even come out) before I buy something. My iPad really does the trick for 90% of what I'm doing on a computer these days outside of work, but my big hitch is Lightroom. I do a lot of photography and rendering in Lightroom is something I really need a computer for. So, I have access to a plethora of iMacs as I work at a College. What I'm wondering is if I could install Lightroom on an external and simply plug it into one of these iMacs so I could do the occasional editing. Anyone know if this sort of thing is possible? Thanks for reading!
