I created a APFS volume on my MacOS 10.15.4 hard drive. diskutil info confirms it is a case-sensitive APFS.
When I untar a Linux-generated archive that contains case-sensitive files, similarly named files that differ only by case (such as File.h and file.h) are being overwritten. I can confirm via tar tfv that the case-senstive files are indeed present in the archive.
However, when I manually create a small test archive with mixed-case files of similar names, it archives and unarchives fine preserving the case-sensitive names.
Why are files being over-written, and is there a work around?
