In your case, Bill you could downgrade your OS and wait until the next major DxO sale and be able to upgrade for closer to €50 than €90.DxO OpticsPro for Photos - DxO ONE Camera Only is designed to provide a seamless image processing workflow for DxO ONE users who are on a Mac, and use OS X Photos as their primary photo application. The real reason behind it is are young developers too listless to bother creating a build on something other than the very latest OS (the latest Xcode always makes it hard to create builds for anything except the latest two OS, hence a developer should be working on a slightly older OS and Xcode to be able ship a single build which will work on three or four OS). It’s as if selling new Macs for Apple was DxO’s primary business. What bothers me is not that the older versions are not supported on new OS is DxO deliberately crippling new versions to only run on the two latest OS. Otherwise DxO has lost a good customer and a public advocate. I won’t be moving past Mojave for another three to five years so I hope DxO has the good sense to maintain support for Mojave in Photolab 5 and Nik 3. I only put High Sierra on my MBPs for the sake of Photolab 3. I’m happily running Mojave on my Mac Pros and High Sierra on my MBPs. I don’t understand why you felt the need to run Big Sur (it’s free?). Software which works through seven OS upgrades is pretty robust. Why did you upgrade? Do you rely on an application that requires macOS Big Sur? I get your frustration but there is nothing to be angry about here really and ranting at DxO is plain unfair. Which would then require you to buy the whole package again.Īlso: your software still works fine but you chose to upgrade your computer without checking the requirements for your version of the software. Most software vendors indeed let you update from the previous version only. Adobe Lightroom subscription would have cost you $840 or $120/year. You can barely develop a roll of film for that nowadays or 2 cups at coffee at Starbucks. I would say exceptional value for your money. You paid $89 over 7 years that is less than $13/year.

So please blame Apple and not DxO/PhotoLab (although they also really shouldn’t be blamed for dropping 32-bit support).

I will not address the haters who suggest that at a specific number of years after original purchase of software I shouldn’t expect it to work without updating/additional $$ outlay. Yeah, I get it and I am not opposed to upgrading at some point, but my concern is that Mac OS updates are notorious for messing up third-party software, so who is to say the next update won’t cause similar problems.
