I love DxO PhotoLab, but find the OS support too short. The renewal of OS at apple is too frequent (every year), also the support of “old” OS by DxO is too short. Other software development companies have understood this well (Topaz Labs, Serif, …) and offer very long support. Mojave is a 32- to 64-bit transition OS that has been the most stable for a long time and should not leave my machine for a few years. Professionals who have a reliable system are reluctant to change (something else to do than always run behind new things), so do like other companies, otherwise many will not follow you. I really like your software in addition it is French which is not so common in the industry. I would like to be able to support the development again, but not at the pace imposed by Apple, so if you do not do like the other companies who have understood this well, I could not continue, too bad for me but also for you.
