Logikcull will proactively alert you when you upload data from a Mac computer. Here's why:
ZIPs created from a Mac’s built-in “compress” option may be incompatible with Logikcull under certain circumstances. This is not a limitation of Logikcull, but rather a problem with how Mac OS treats zip encoding.
If you encounter an issue uploading data received from someone using a Mac, we recommend unzipping the data and re-zipping with a commercial utility like Keka.
More information on Keka's settings can be found here.
