Hi, I was hoping someone could help with a file issue we’re experiencing on Mac. Some of our customers have reported unzipping issues with our files, which only seems to affect Macs. The problem only occurs with our larger downloads (5GB plus). In order to cater for both Mac and PC users we remove all the Mac files on a PC (Windows 7 Professional), zip the file on the PC and then upload them to our Amazon S3 server. Smaller files don’t seem to cause any issues, but larger file show up with the following error on Mac: Unable to expand “file-xyz.zip” into “Download Location” (Error 1 - Operation not permitted) Strangely this error only seems to occur when using the in-built unzipping software, but if the file is being unzipped with ‘Unarchiver’ it works fine. I have been told this could be caused by us zipping the file on a PC, and while we have found some software that removes Mac files from a zipped file on Mac itself, I was hoping I could get another opinion on this. Thanks!
