I'm running LR 4.1 on an older Mac with 1GB RAM and OS X 10.6.8. LR 4.4 update specs indicate I need 2GB RAM. Is it possible to run LR4.4 on 1GB or am I stuck with upgrading my RAM or buying a new Mac? Also, I just purchased a Canon 6D and LR 4.1 will not recognize raw files from the 6D. Will that problem disappear if I install LR 4.4?
2 GB RAM is the bare minimum required. But you'll get very poor performance even with that. You would be much happier with a gigabytes or more of RAM if you want satisfactory performance.
