Marked as implemented, macOS build for x64 systems has been out for a while now - and is the only option now with 5.44.
In case there are issues with it, please post in Tech Support and we'll take a look. Standalone 5.44 is getting delayed because hampa's still working on getting it notarized with Apple; it should be also available once it's resolved.

Windows version will stay 32-bit for now but we may move on to 64-bit only as well in future.
