I am ready to buy PhotoMechanic and wondered what the status of Sierra support is before I install the PhotoMechanic on my travelling laptop (trial was done on my main desktop machine which has El Capitan installed).
Fully supported, though that doesn't mean that macOS Sierra doesn't have bugs or that PM will have no problems of any kind on the new OS. What supported means is that we've tested PM on macOS Sierra, it is working well, and that if any problems do crop up, we'll be fixing them straight away.
I also wanted to know if there are any active discount codes. I found a few but they are all expired.
I do not know, but you can contact the sales office to inquire. +1 503.547.2800
