Even if I marked this question as solved, I would like to add some thoughts here. But first of all, thank you very much for your notice that you are working on this issue. It is far from my intention to get anyone into trouble here by persistently asking questions, and I am also aware of the difficulty of communication as a listed company.
Nevertheless, I would like to add the following thoughts to this discussion:
The topic, which in the long run is a migration of the Mac version of Arnold from Intel to M1, has not been here since yesterday. In fact, this move has been looming for 1.5 -2 years now. Most players in the industry have reacted early with roadmaps, careful communication or even public beta versions to the coming transition. So some of your competitors were able to build trust in their products very early and also help users to plan their hardware strategy carefully.
The interim solution via Rosetta two - which I have now been working with at least since R25, was already a compromise. The advantage of new Fast Mac hardware is actually relativized again. I have been able to accept this as an intermediate step in the migration. With S26, support has now completely disappeared for us from one day to the next. Staying on R25 is certainly a possible solution, but also one that makes me very uncertain about the future. How long will this situation last? How long do I have to wait to use an actually excellent update from Maxon - because of Arnold? Will there be a solution until the next release? Such questions actually annoy me and are not acceptable without good communication. And - they are also not fair to us users. After all, we pay annually for our licenses, which are currently of very limited use.
And - finally, based on the views in this forum, I notice that all entries on this topic have been viewed incredibly often - compared to the average of the other questions. It seems that this issue is a serious problem for many users. Also the fact that within a few days you seem to have adjusted the Relasenotes to this question again, shows me that there is indeed a serious problem.
My thought or my consideration was therefore that this adjustment calms me down less, but worry me more. I think that the communication from your side would be much more relaxed if the release would be soon. Instead, I just fear that this one will indeed take quite a while. I would like to emphasize that I really draw this conclusion from the really helpless communication. This cannot be in the interest of your company either!
For the sake of fairness, I would also like to note that the GPU situation was already known and communicated and explained here by you. I can absolutely understand and accept that!
Nevertheless, I had no choice but to decide today as the only safe solution for me and our Team is that we will not start any new projects with C4D / Arnold from now on and have extended my Maxon license with another renderer at the same time. This solution is really not what I wanted or found ideal either. Even more - I think it's a real pity, because especially for my studios I considered Arnold as a really perfect tool.
At the same time, we have arranged through our dealer to be reimbursed for our license costs and to be able to return it. Apparently Autodesk is still resisting, but according to German and Swiss law they will have to.
I find this really unbelievably unfortunate and it annoys me. I don't remember ever experiencing such a situation in my more than twenty year career in photography and 3d. I still hope very much that someone will find a way to communicate in a reasonable and fair way and show us users how and when a reasonable working with your tool is possible again for the Mac community - without us having to stay on R25 or using PCs.
Please excuse my harsh words here - I have always appreciated Arnold and your support!
