Do you have problems with Veeam Entpoint Backup or Windows Backup fails with VSS error 12289 on a iMac? Just disable the Apple HFS driver and reboot. I use Autoruns from Sysinternals for that:
After that you have no access to the OS X HFS partitions, but for me this is no problem. I haven’t use that any time.
