For those of you considering upgrading to the new Mac OS X 10.10 « Yosemite », beware.
While Adobe Photoshop Lightroom 5.6 does support very well the new version of the OS, it is not the same for its plugin.
I identified at least 2 majors plugins being broken:
- NikSoftware by Google (plugin reported to show up activation window for registered users)
- Perfect Effect 8, both standalone and plugin are broken « problem communicating with the background process ».
If you work regularly with those softwares, consider to wait until their respective publishers issue an update.
