Where did the Jumbo frame ethernet setting? All my equipment has remained the same and in the Mountain Lion I could choose MTU 9000 in the network settings.
iMac, OS X Mavericks (10.9), 21.5-inch, Mid 2010
In the same place of every last OSXs:
Preferences-->Network-->Ethernet-->Advanced...-->Hardware ... here you set manually the interface MTU.
Yep in the same place but jumbo frame support has disappear !!!
You can only choose 1280 to 1500 MTU...
What a shame !
MTU support of 9000 is no longer available on my 15 inch Mid 2010 MacBook Pro 2.66 i7 after upgrading to Mavericks. How ever my Early 2008 Mac Pro 2x 2.8 Quad-Core Xeon still has 9000 MTU support after upgrading to Mavericks. Is jumbo frame support in Mavericks tied to specific machines?
My machine pre Mavericks was reading from my NAS at an average of 110 MB per second. Post Mavericks I am averaging 66 MB per second. I have seen it peak above 80 MB per second, but sustained is consistantly in the 60 MB per second range.
Hi,
Same here on a MacBook Pro 2010, i5 2.4GHz, 15" Anti-glare HiRes display.
Lost jumbo frames with Mavericks upgrade, worked fine before with a TrendNet gigabit switch and a Synology DS213j NAS.
Please Apple, fix that... along with the display glitches!

My mid-2011 Mac mini (not server) presents an Ethernet MTU choice of Standard (1500), Jumbo (9000), and Custom MTU settings in OS X 10.9.1. Keyword Ethernet. You won't have Jumbo frames option with Wi-Fi or Thunderbolt Bridge selected.
My early 2008 MacBook Pro (Lion) on the same network as above, also shows Jumbo Frames available. My Gigabit router is an Apple Airport Extreme.
Though unsubstantiated, Mavericks may have raised the bar for what constitutes an acceptible Jumbo frame handshake with your non-Apple Gigabit network device. I would disable, and then re-enable Jumbo frames configuration on the network device to discern it this capability is restored.
Works for me in OS X 10.9.2
It has been working fine with my machine (MBP early 2011, 17'') until to the 10.9.5 update. See here: can't access smb shares after 10.9.5 upgrade
No Jumbo frame in Mavericks?
