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.

1157 On my older TB3 Mac, my 10GbE sometimes becomes non-responsive.May-13-22
If you are using a MacBook Pro (2016), iMac Pro (2017), iMac (2017) or iMac (2019), and you are connecting another Thunderbolt device to an adjacent TB3 port; and your 10GbE becomes non-responsive (but may still appears as available), then connecting your Solo10G or Twin10G to the Thunderbolt port on the right may resolve the issue.
