I just go the new macbook pro, but it doesn't have a cd drive. I already own the Lightroom software on a disk. How do I install my Lightroom?
Download Lightroom from Adobe (the trial is really the full version but simply needs a serial number to run fully) and use your serial from the disc package. Alternatively if you have very slow internet you can share the CD drive from another Mac that has a CD drive and mount the CD on your MBP. Go to your control panel on the Mac with the drive, select sharing and enable DVD or CD sharing. It will show up as a drive on other machines on your local network. You shouldn't have to do this as the download is much simpler and faster in general.
