Honestly, I just tried downloading the Mac version today, and magically it worked. Probably Mr. Daisy fixed the link or something. I have no idea.
Anyways, I recommend not getting too hyped. The new update is too short and focuses way too much on sex than in the story. I kind of regretted trying so hard for so many days to download it, just to get 10 minutes of new content…
But if you decide to keep trying, I wish you luck.
