exfat external drive

[lowendlinux]

I have a really nice 3TB 2.5" external drive that I use between my Linux boxes, my work MP, and my daughters Windows PC, and supposedly my 10.11 iMac. The drive works fine on everything but the iMac. I tried google and it sorta told me to input defaults write com.apple.DiskUtility advanced-image-options 1 into the terminal and I did and it still doesn't work. Does anyone else have issues with an exfat external in El Cap?

Did you use Windows to format the drive?

Is the external disc shown in Disk Utility when it's connected to your Mac?

Interesting, have you tried clearing the drive and formatting it using exFAT on Windows?
