Thanks very much for the info.
I am traveling in South America and since the laptop is "the" computer, I ve been treating it like its in a production environment. I ve resisted the 10.9.5 beta and Yosemite as well. The apps I have that are critical for me are Lightroom 4, Soundflower, and AU Labs audio processing. Hopefully under 5, things will run as now. I continue to resist Adobe's efforts to move everything to the cloud and a monthly fee to rent their apps.
Regards and again many thanks
