What workaround for macbook will allow me to open this?
Viewing post in Cosmica Chrome Cursor Pack comments
Inside the download there are the cursor files (.cur and .ani) and an auto-installer for windows only, so for mac ignore the installer. I don't have a macbook myself so I can't experiment with adding cursors. I searched for tutorials on youtube and this one is the most popular so you could try it out: www.youtube.com/watch?v=Oyv7oxrSWZ8 . It might include converting the file types which you can do online by searching for file type converters.
Macs are not very custom-cursor friendly so it's definitely not easy! When I have the opportunity I'll try it out on a friend's macbook and see what I can do to make the files as easy to intergrate as I can.
