> Lightroom just work[s] a ton better on Windows That’s not my experience, at least with Classic. Mine is a Mac house. My parents, though, are long-time Windows users; I only managed to get my parents to run a single iMac, which they gave away as soon as they could financially justify it. I tell you that because that is where my cross-platform Lightroom experience comes from: almost all Mac, with occasional mentoring/support sessions under Windows at the parents’ house. With Lightroom on Windows, I’ve repeatedly observed: 1. Windows’ brain-dead default-mandatory file locking prevents perfectly reasonable operations, simply because Lightroom is busy working with one or more files in the background. Advisory locking as is default on POSIX type systems allows many things that Windows refuses to allow by default. (E.g. Rename a parent folder while a file in that folder is open for writing. Who cares, the FD is still valid!) 2. Lightroom can take a long time to shut down when it gets busy, as it too-frequently does. On the Mac, the app icon remains marked “running” while Lightroom grinds away, trying to figure out how to shut down, but on Windows, the app icon disappears from the task bar almost immediately, but Lightroom.exe remains running in the background, so that it is not obvious why reopening the program fails for minutes at a time. (And why reopen? Because relaunching Lightroom often solves slowdown problems, and has for years upon years, which is a separate rant.) 3. Some plugins simply won’t run on Windows, at least not without dragging along a bunch of compatibility junk. Anything that depends on ExifTool, for example, requires dragging over a whole Perl environment just to run the plugin. If you have multiple plugins dependent on ExifTool, as I do, each one usually comes with its own Perl environment. Compare macOS, where at worst you have the CPAN module alone, and at best, it might simply require that you install ExifTool separately, that being a reasonable user requirement on an OS like macOS. If your comment was referring to GPU acceleration and such, Adobe’s recent focus on that isn’t helping me anyway. Almost all of my problems with Lightroom’s speed are in the Library module, not the Develop module, where GPU acceleration doesn’t help much anyway.
