Adobe has been churning out steady releases of Lightroom for nearly 10 years now – since the very first beta hit in 2006. I’ve been using it since those early days and it was a fresh take on non-destructive image editing. It is a fantastic program for both developing and organizing RAW image files.
It is supported over a wide range of operating systems for both Mac and Windows computers. However, that list of supported systems is about to drop.
As is the case with nearly all evolving programs, there comes a time when legacy hardware or software gets cut off from further development. For Lightroom 6, that means 32-bit operating systems will be dropped in favor of a purely 64-bit future for Lightroom.
Accordingly, if you run Mac OS X 10.7 or lower or a 32-bit version of Windows, you’ll need to upgrade before you install Lightroom 6. Specifically, Lightroom 6 will support OS X 10.8 or above or 64-bit versions of Windows 7, 8 or 8.1 (presumably that means Windows 10 will work fine as well).
