Configure Samba to Work Better with Mac OS X
Recommended fruit config
Below is a working recommended fruit config:
[Global] vfs objects = fruit streams_xattr fruit:metadata = stream fruit:model = MacSamba fruit:posix_rename = yes fruit:veto_appledouble = no fruit:nfs_aces = no fruit:wipe_intentionally_left_blank_rfork = yes fruit:delete_empty_adfiles = yes [TimeMachineBackup] fruit:time machine = yes # fruit:time machine max size = SIZE
Beware! This configures VFS objects in the global section, setting vfs objects in a share will *overwrite* the globally configured option, it will NOT supplement them.
Below are suggested parameters to use in smb.conf file of the Samba server to improve operability with Mac OS X clients. Note that some parameters may not work with your version of Samba - read the smb.conf and vfs_fruit man pages (on Linux) for your system. Other than those shown in the [TimeMachineBackup] share below, I recommend you include all parameters in the [Global] section of smb.conf. For ease of copy > paste, a clean smb.conf section is included at the bottom of this page.
Apple extensions ("AAPL") run under SMB2/3 protocol, make that the minimum (probably shouldn't be running SMB1 anyway...) - defaults to SMB2_2 in Samba 4.11+:
min protocol = SMB2
Apple extensions require support for extended attributes(xattr) - defaults to yes in Samba 4.9+:
ea support = yes
Load in modules (order is critical!) and enable AAPL extensions:
vfs objects = fruit streams_xattr
How to store OS X metadata:
fruit:metadata = stream
For additional setting see the manpage vfs_fruit.
Server icon in Finder (added in Samba 4.5):
fruit:model = MacSamba
fruit:veto_appledouble = no ...added in Samba 4.3 fruit:posix_rename = yes ...added in Samba 4.5 fruit:zero_file_id = yes ..added in Samba 4.8 fruit:wipe_intentionally_left_blank_rfork = yes fruit:delete_empty_adfiles = yes
For Spotlight backend indexing using Elasticsearch (added in Samba 4.12):
[share] spotlight backend = elasticsearch
See smb.conf for 4.12 for other Elasticsearch parameters. Gnome tracker is still available (= tracker) or no indexing (= noindex), the default.
For Time Machine backup share (added in Samba 4.8):
[TimeMachineBackup] vfs objects = fruit streams_xattr fruit:time machine = yes
As far as I know, testparm will not validate vfs_fruit parameters. (my server runs an old version of Samba :-), but after you have built your smb.conf, you can check for errors anyway with
#: testparm or
#: testparm -v (which will give you the defaults as well.
From Finder, connect to your Samba server using
Note that TM backups over smb may now be possible with your server.
Other Mac models can be found in "/System/Library/CoreServices/CoreTypes.bundle/Contents/Info.plist". Use "Quick Look", Xcode or plutil to view or convert plist.
File Permission issues
Setting the global option
fruit:nfs_aces = no will prevent macOS clients from modifying the UNIX mode of directories using NFS ACEs. An Access Control Entry (ACE) is part of the Access Control List (ACL).
