To be honest, @gregor this is not at all what DxO should be telling its users. 2020’s Apple are corporate rats engaged in share buyback to pump up their options, while doing the maximum amount of damage to the environment. Butterfly keyboards break with a single crumb: outside of Apple care you may as well throw away your computer. Only the top and bottom of an Apple laptop are now replaceable (gifted third parties can work around this somewhat with scavenged parts), making a battery or a keyboard replacement an €1100 fix.
Apple is doing untold damage to the environment and robbing their users with their repair and upgrade unfriendly policies. It’s all for the sake of executives’ share options. I really don’t think DxO should be adding and abetting such a destructive mission.
@Lucas Thanks for your detailed reply.
I just wanted to make clear that DxO doesn’t drop older OS versions just for stupid reasons…DeepPRIME on macOS uses a technology called Core ML. This is what runs our DeepPRIME algorithms either on GPU or on CPU. Machine Learning is a rapidly evolving area, as such Core ML already existed in macOS 10.13 but was a lot more limited than it is in macOS 10.14. As of today, DeepPRIME cannot work on macOS 10.13 without writing workarounds for these limitations.
I really appreciate you taking the time to explain the specific issue. In this case, if DeepPrime can’t run on High Sierra without a lot of trouble, it would be fine to have DeepPrime disabled/invisible on High Sierra. You’d say DeepPrime is the core feature of Photolab 4. Sort of. The core feature of Photolab 4 is Photolab 4 itself. By allowing Photolab 4 to run on High Sierra but with Prime instead of DeepPrime, you’d allow full cross-compatibility for users like me who have their two of their main computers stuck on High Sierra due to Apple policies but do have access to a machine with Mojave.
FYI, my MacPro 5,1 is EOL’d at 10.14, Mojave. I will not be replacing it for another three to five years. There are lots of us out there. I highly suggest DxO maintain Mojave support as long as possible.
This computer is 12 x 3.1 GHz (was 3.33 GHz but runs quieter at 3.1), Radeon VII with 3 x 4 TB SSD, 2 x 2 TB SSD, ultra fast ACHI 1 TB drive, 1 x 10 TB spinning drive. And that’s counting only internal drives and I still have three slots open. Apple’s only comparable computer in terms of flexibility and expandability would cost me about €15000 in a similar configuration.
In any case, a new build which would run on High Sierra but without DeepPrime would be much appreciated by many in the photographic community. I don’t even mind if that build is not officially supported.
