Hi,
thanks for that! I can confirm that this file, or other that are create with the “Compress” feature on a Mac can not be imported, it seems. My guess is that these files don’t fulfill some sort of specification, so that they don’t meet certain consistency checks when PHP tries to open the ZIP file. Now, maybe TablePress/PHP is too strict there, and I do see a configuration variable that I could adjust to maybe allow these “inconsistent” ZIP files to work. I’ll have to check for other side effects that such a change would have though, first (e.g. security implications).
Right now, I can therefore only suggest that you import these tables one by one, or maybe use a dedicated app for compressing the files, e.g. https://www.keka.io/ When I use that to create a ZIP file with the CSV files that you sent, the import works for me.
Now, what I find curious is that such an issue has never been reported to me before – and you most likely were not the first person to try to import a ZIP file that was created on a Mac… Maybe Apple changed how ZIP files are created on a Mac? What exact version of macOS are you using?

Tobias
