I don't think that's a fair comparison. Parallels comes with dkms module and while the process of installing involves compiling under the covers, it's just part of installation. It's not the late 90s "compile that driver yourself completely manually" situation.

If Parallels doesn't work with new kernel, that's their compatibility issue, but being able to fix the driver yourself just gives you more options. Linux -> you can fix the driver. MacOS -> you can on new macos, with annoying extra signing and other steps. (if the source for macos is even published - for parallels that's a no) Windows -> basically wait until the vendor produces an upgrade.

Parallels says for macos 12: "Productivity and integration features are not available to this VM yet." Even if you wanted to fix it manually - you can't. (https://kb.parallels.com/au/125561/)

Basically, you get the extra option to upgrade faster than your vendor is ready on Linux - if you use that path, why show it as "I had to do manual work to make things work", rather than something positive?

Not OP, but I do want to note, there is a difference compared to windows: Windows has a stable driver interface, which makes it at least possible to have drivers that are basically guaranteed to be future-proof. Linux has no such stable ABI, and frequently does breaking changes.

Both approaches have their upsides, but I've very rarely had drivers stop working between various windows release. Of course, there are exceptions to the rule here - Yes, I also have had some drivers stop working since Windows XP. But those are rare, and getting rarer as time goes on and MS locks the kernel up, preventing drivers from doing stupid things.

On Linux, the problem only exists for out-of-tree drivers, but those will break fairly frequently for all but the simplest drivers.

As I said in my sibling comment, I don't know how I feel about a stable ABI - I do fear it would make the situation worse with more out-of-tree/proprietary drivers. But it is worth keeping in mind that it does have its upsides.

Of course, MacOS being what it is, it chose the "worst of all worlds" scenario: Proprietary drivers with no ABI stability guarantee. It's not really worth discussing as a point of comparison, MacOS has the worst driver story from the lot, only saved by its intended minimal target hw support.

I don't understand. Do you think I'm lying or something? Because I'm not, and neither are these folks:

It's a giant pain in the neck and it's caused by pretty deliberate decisions about Linux architecture.
