Now i'm looking for the most accepted file sys to share files between them, so far i've found these options:
I've a laptop with triple boot, Yosemite, Windows 8.1, CentOS 7, and need a partition for sharing files between the 3 os's, i've been using exFAT, as it is supported by OSX & Windows but had some issues with linux and after try to mount it on linux, osx didn't recognize it, and i was unable to mount it, then just windows recognized it and after 1 day of using it got corrupted, i had to get my data back with TesDrive.
