I've just got around to installing VMware Fusion 8.0.1 (upgrading from version 7) and ran into the same problem: installation of the tools failed in all VMs running OS X 10.5 through 10.7 (so far, and I expect I'll have the same issue when I update my 10.8 through 10.10 VMs), reporting an error with the postinstall script.
I had a look inside the postinstall script using Pacifist and have a theory as to the reason for the error.
The script ends with this:
# Up to Mac OS 10.11 Developer Beta 2 (15A204h), mount(8) searches for
# mount_<fs> in the following locations, in this order:
# /sbin/mount_<fs>
# /usr/sbin/mount_<fs>
# /System/Library/Filesystems/<fs>.fs/Contents/Resources/mount_<fs>
#
# Starting with Mac OS 10.11 Developer Beta 1 (15A178w), System Integrity
# Protection is enabled so even root cannot write to any of these locations.
#
# Starting with Mac OS 10.11 Public Beta 1 (15A215h), mount(8) searches for
# mount_<fs> in this 4th location, which root can write to:
# /Library/Filesystems/<fs>.fs/Contents/Resources/mount_<fs>
mkdir -p /Library/Filesystems/vmhgfs.fs/Contents/Resources
ln -s '/Library/Application Support/VMware Tools/mount_vmhgfs' \
/Library/Filesystems/vmhgfs.fs/Contents/Resources/
if [ "$macosMajor" -lt 15 ]; then
ln -s '/Library/Application Support/VMware Tools/mount_vmhgfs' /sbin/
fi
I ran each command manually and they all worked except the last one, which creates a symbolic link in sbin.
$ sudo ln -s '/Library/Application Support/VMware Tools/mount_vmhgfs' /sbin/
Password:
ln: /sbin//mount_vmhgfs: File exists
The earlier version of the VMware Tools had copied mount_vmhgfs to /sbin/ rather than creating a symbolic link. Replacing it with a symbolic link requires removing the previous file first.
