I'm wanting to perform basic healing edits on some of my photos. I can send the photo from Lightroom into Pixelmator just fine from the Edit menu but when I make edits on the TIF in Pixelmator the TIF doesn't get passed back to Lightroom. I've Googled this issue and it seems to be a common problem, with several workarounds, none of which seem to work. This is the latest one I've tried, with no luck. http://support.pixelmator.com/viewtopic.php?f=3&t=9895 I'm on the latest versions of Mountain Lion and Pixelmator. Lightroom 4.4. Any ideas?
