972 After I upgraded macOS, the Twin10G, Presto 10GbE, or other Sonnet PCIe card that requires a driver is not loading.Dec-22-19
If you have already installed a Sonnet Driver and it is not loading:
1) Restart (forces Mac OS to scan for unloaded drivers).
2) Go to System Preferences...Security & Privacy panel...General tab. You will see a message, "System software from developer "Sonnet Technologies" was blocked from loading." Click Allow. Note that you must have a hard-wired mouse/trackpad to click allow. If you are connecting via Remote Access, then macOS prevents you from clicking Allow.
3) Restart.
 
974 Can I get increased performance from Link Aggregation in macOS?Dec-22-19
We have found that a macOS client just ping-pongs back and forth between the two ports with no increase in performance. There is an increase in performance with only a macOS server that is connected to multiple clients. To get link aggregation to work, the switch must be capable of supporting it and the two switch ports connected to the Twin 10G must be configured as bonded ports.
 
993 My system crashes, freezes, or fails to connect when I talk to a storage device on the networkMay-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.

1065 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.
