I am trying to install XP11 from DVD on a Mac (Retina 5K 4GHz Intel i7 running OSX 10.13.3 High Sierra). Despite multiple install attempts, the error message "No such file or directory" triggers after scenery disk 3 is inserted. I've followed the advice to install to the desktop and have tried multiple workarounds including selecting regional scenery, selecting all scenery and manually installing the scenery folders/files from the disk. All produce the same result. There's no issue with the disk drive.
