can you make a older version for iMac version 13 or lower i have a older mac that dose not support mac version 15 i would appreciate it.
(Assuming you are referring to macOS 10.13, not macOS 13,) I don't think Qt 6 supports that version, so it might not be possible to use Shijima-Qt on macOS 10.13. The automated builds also only support arm64 Macs and I am unable to test compatibility with Intel Macs, so I can't easily add support for older macOS versions. Sorry about that.
