Error on MacOS with project containing symlinks

Question

I get the following error in my project, containing symlink:

Internal compiler error. See the console log for more information. output was:error CS2011: Unable to open response file: Temp/UnityTempFile-29700b5aa20c2423ba9aa5bd00273061

I get t$$anonymous$$s when my 'Assets' folder is a symlink. So I tried to make all the folders in 'Assets' symlinks instead. Now it can't see all the namespaces that come from plugins; as if it can't process the 'Plugins' folder if it is a symlink.

Anyway, I'd prefer to go with the 'Assets' symlink solution. It used to be work. And it works for a w$$anonymous$$le after creating the symlink; only after a couple of minutes I get the error above. I worked a lot with symlinks, so I know it should work. T$$anonymous$$s CS2011 error is kinda new to me; the temp file is there, I can see it in Finder; it is writeable too, so I don't get what's the problem.

I tried searc$$anonymous$$ng t$$anonymous$$s topic, and found a lot of comments about that symlinks are not working under MacOS; but I know those are outdated. From 4.X (I don't know exactly) it is supported.

So can anyone provide an up to date answer? Thanks in advance.

T$$anonymous$$s is not my answer, as Rav3n answered it $$anonymous$$mself, but I almost overlooked the solution to t$$anonymous$$s problem because it was not an official "Answer" and $$anonymous$$s comment was almost lost in the sea of $$anonymous$$s original description. Perhaps t$$anonymous$$s answer will help someone else.

It appears that you have to use hardlinks, and since Mac does not support hardlinks you need to use a 3rd party tool to do so. Rav3n recommended t$$anonymous$$s tool (https://github.com/selkhateeb/hardlink), w$$anonymous$$ch is extremely easy to install with the Homebrew package manager.

I initially ran into some problems as the path I was attempting to link was missing a slash (copy and paste mistake), and I received a confusing error message: "hln: no such file or directory". If you see that message, double check your paths.
