Hey hey! You don't need to apologise :3 It's not a bother at all. I just wish I had a Mac so I could attempt to help people more x3
That's very strange that SR actually works for you because normally it's the other way around for people, haha. The major difference is that SR was made in Tyranobuilder engine. Whereas LiL and DD were made in Unity. SR is the one that I've had a lot more trouble with on Mac in the past and one of the reasons I stopped using the engine altogether. A few devs had asked the engine devs what to do because so many Mac players couldn't even open their Tyrano games exported for Mac. The engine devs eventually responded with something along the lines of, Macs are just awkward. It'll work for some and not for others. There's nothing we can do about it >.< I just thought that wasn't the greatest attitude to have, so I switched to Unity thinking that it's so well-known, surely there won't be any issues. But I guess I was wrong >.< And not knowing anything about how Macs work, I'm confused as hell as to why it seems to be 50/50 as to whether it works or not!
Now, there is a rare problem for some Windows users, where the Unity splash screen shows, then it just black screens. You can hear the title screen music, but you can't do anything cos it's a black screen. For some reason, the cause of that issue seemed to be the fact that there's an mp4 video file playing a video background on the title screen. I was able to fix that for those having the issue by replacing the video background with a static png version instead.
I'm guessing this isn't the same issue, and you may have already tried this, but if not, try going back to the file downloads and get the one called 'Possible Black Screen Fix (Mac)'.
It's got the same fix in it as for Windows with the static title screen rather than the video one, but since I have no way of testing it myself, I can't confirm if the issue even exist on Mac, let alone if that fix would work >.< LiL doesn't have a video background on the title screen though, so if you've got the same problem with that, I'm not holding out much hope that the same fix which works on Windows will work on Mac :(
Let me know anyhow. I'll see if I can do some digging when I get a chance. I've seen plenty of complaining on the Unity forums about endless Mac problems, but this might be different because you've actually managed to launch the game. Which means it could be an issue with Naninovel instead. I'll see what I can find by searching through support. Please don't hesitate to contact itch and get a refund though if it looks like it's gonna be impossible to figure out! I really would love to find a way to fix these problems though. The trouble is, I don't personally know anybody with a Mac, and so I have no way of going back and forth trying different things to see what might work >.<
Sorry for the hassle >.< I hope you have a lovely weekend despite the trouble with this :3
