exFAT is a relatively new file system introduced by Microsoft with the Vista OS. It is frequently used in Windows 7 installations as well. Many Apple users need the ability to access exFAT drives — especially shared external hard drives. Can Apple computers use exFAT drives?
As previously discussed in our exFAT versus FAT32 versus NTFS article, exFAT is a good modern update to Microsoft’s file system. However, previously Apple OS X users have had difficulty accessing exFAT drives.
However, with OS X update 10.6.5, Apple fully supports accessing exFAT drives.
Once you update Snow Leopard to the latest update, you should have full access to exFAT drives without any difficulties.
