It's most probably caused by the new APFS file system in High Sierra. By default, your boot disk is converted to the new file system when updating the OS. There's something in the new FS that causes alphabetical file lists to go out of order. The same thing happened in the preset browser of u-he synths (preset list should be alphabetical, now more or less random), probably elsewhere too.kv331 wrote: if your MacOS system does not sort files by name in ascending order, some factory waveforms will not be read.
EDIT: And here's the exact reason, from https://developer.apple.com/library/con ... Q/FAQ.html
Calling readdir(2) on a directory in APFS returns filenames in hash order, whereas HFS+ returns filenames in lexicographical order.
