It seems that some users are using Lovely Composer through emulation on Mac and Linux. (Probably like Wine)
Even the M1 Mac seems to work, so it might be worth trying on your own computer with a free trial version! If the trial version works, the official version will work in most cases. (We don't support officially & don't know the details)
We want to officially support Mac in the future, but We don't have a new Mac so far. (Although there is an old Intel Macbook from 2009 ...)
