| My system crashes, freezes, or fails to connect when I talk to a storage device on the network | May-13-22 | | Go to System Preferences...Network.
Select the 10GbE port and click "Advanced..."
Select the Hardware tab.
If Jumbo packets are on, turn them off, click OK and click Apply.
If that fixes the problem, then stay at Standard (1500), or check the Jumbo packet setting of every switch and device in the path.
If that doesn't fix the problem, check Flow Control.
If Flow Control is off, turn it on; or if it is on, turn it off. Not all devices support flow control, or the absence of flow control. | |

| I'm getting very slow performance with my Presto 10G PCIe card or Twin10G Thunderbolt 10G adapter with OS X 10.11-10.12. | Dec-22-19 | | In macOS 10.11 and 10.12, SMB signing is turned on by default. This is no problem for gigabit ethernet, but SMB Signing severely limits the performance of 10 gigabit ethernet. Apple has published a tech note how to turn off SMB signing: "Turn off packet signing for SMB 2 and SMB 3 connections". This note requires the use of the terminal application and a number of terminal commands, so some familiarity with those tools is required.
In macOS 10.13.6+, Apple has turned off SMB signing by default. | |
