Slow SMB transfers in Mac OS 10.12.2

I’m using a 802.11ac WLAN to connect to my Synology NAS. With the last Mac OS 10.12.2 update the network performance was catastrophic when I tried to access the NAS via SMB. At first I thought this might have been caused by the WLAN connection but even with a Gigabit LAN connection my transfer rates were around 3-5MB/s.

After a short search online, I’ve a few hits describing the actual problem:

Apple uses their own version of SMB and enabled client signing to mitigate against Man in the middel attacks. Therefore all connections underly this signing process and are way slower.

Therefore I’ve disabled client-signing on my mac using this command:

to the file /etc/nsmb.conf. After you’ve set this value you need to unmount all samba shares. If you’ll reconnect now, you’ll witness a much better performance, starting with faster loading of network shares.

Automount network shares on Mac OS for use in iTunes

I’ve moved my iTunes library from my Macbook’s SSD to my Synology NAS on a network share. This is quite easy and can be made inside the iTunes preferences pane. After you’ve changed the path for the iTunes Media, all iTunes managed media will be moved to the new location (assuming you let iTunes manage your files of course :)).

This allows you to have your iTunes library on your Macbook while all the large files are stored on the NAS. This is especially important for larger libraries as well as the newer Macbooks which only have a limited flash drive instead of larger harddisks.

However, there is one important problem with this solution: Once you’ve disconnected from this network share for whatever reasons and you try to start iTunes, you’ll have your iTunes Media folder reset to your user’s music folder on your boot disk. You’ll now need to reset the path to your files again, and this will again cause iTunes to check all files if they are on the right location and moves them if necessary.

I thought I’ve taken care of this problem with auto connecting to the network share with a Login Item. However, this didn’t help me much since I sometimes have disconnections to my network (e.g. when I’m on the road) and the network connection will only be created once during the login of your current user. So this doesn’t help me at all and caused me to look for another better solution.

So I’ve found this gist (the link is dead) and modified it a little bit to my environment. Therefore here’s my short list of modifications for using autofs in combination with AFP or SMB volumes:

If you now start up iTunes again, it will try to locate the media files in the /Volumes/music folder, like I manually specified it. However, autofs will now automatically mount the network share for me and iTunes won’t complain about a missing volume. This way I won’t ever need to take care of manually updating the path once I forgot connecting to my NAS 🙂

Update:
Hm, it seems that the trick with /../Volumes does not work anymore on Mac OS 10.11.4 🙁 If I try to list the content of the mounted volume an error message is returned:

ls: : Unknown error: 118

So I need to mount the volume in a different folder and need to change the path in iTunes again.

Update 2:
I’m not able to mount afp volumes anymore so I’m using smbfs like it is described here. However, this will require a user and password in the configuration file 🙁

Update 3:

Mac OS Sierra breaks the autofs configuration. I had to change it a little bit according to this SuperUser entry. The Gist is updated accordingly.

How to remove Spotify’s notification badge from the Mac OS X dock

Are you also annoyed and tired by Spotify’s notification badge in the dock of Mac OS X? I totally was and found a simple list of instructions on apple.stackexchange.com and want to show you how to remove this „feature“.

If correctly used, notification badges are a cool thing. They notify you when an app wants your attention. Spotify abuses this feature and shows the number of pending notifications inside its app. That means: If you ever subscribed to somebodies playlist and this playlist is updated, you will be notified. Same goes for stuff like new tracks of your favorited artists. You have no control over these notifications and will always be notified. Other users are also annoyed by this misbehavior but nothing changes 🙁 Thats why my Spotify is mostly minimized to the background and when opened it shows this ugly notification badge in its UI:

Spotify in app notification badge

Its annoying and always tries to steal my attention. Same goes for the Mac OS X dock icon:

Spotify Dock Icon with 99 notifications

Normally, you can open the system preferences and can disable the notifications. However, Spotify isn’t listed (although it uses the notification APIs of Mac OS X).

The instructions from stackoverflow write this missing entry into the notification database, so that it shows up in the list. Only after that you are allowed to disable Dock notifications:

Forward Kodi/XBMC video information to hyperion on Raspberry Pi

My current network setup allows me only to use small bandwidth connections between the living room (that’s where my Raspberry Pi is used as my Mediacenter) and office (my NAS). However, my Macbook is fast enough and can access the NAS wirelessly, so that I often use it as a replacement for the hardwired Raspberry Pi.

However, I cannot use my Hyperion Ambilight setup behind the TV in combination with the Macbook, because its only connected to the Raspberry Pi. But yesterday I’ve found this plugin which enables the Kodi setup on my Macbook to connect to the Hyperion Server on my Raspberry Pi over network.

  1. Download the zip file with the content of the git repository.
  2. Start Kodi on the Macbook and install it using the add on manager. You can point to the zip file directly without the need to unzip it first.
  3. Configure the installed plugin to connect to the ip of your Hyperion server.
  4. Start a video and be amazed that the lights on your TV will work wirelessly 😉
