Install worked; LR 2015.8 seems to work. But, tethering to Canon T5i fails. The camera may or not be recognized. A photo taken is not presented on the LR screen. No specs are available for adjustment from the MacBook. Pro (early 2011) using OSX Sierra.
The latest LR CC update on PC/W10 works fine, including tethering.
This is the list of cameras with tethering supported in Lightroom A list of cameras that can be tethered to Lightroom.
Also worth noting that Canon have recently released a new tethering SDK to address issues. I expect same will be incorporated into Lr at some point.
