I have an older version of adobe photoshop that I used years ago on my windows pc and have now made the transition to mac os x .I haven't used my camera gear nikon d80 and d300 much in the last few years and now have the urge to get back into it.Any suggestions on upgrading to a newer version of LR or maybe give Aperture a try ? . I'll be using the software on my 2012 i7 mac mini or 2008 MBP upgraded to 8 GB ram owc SSD.
