Not so much a problem with the Powerline device - but a heads up about the MacOS version of tpPLC used to manage them.

The downloadable version of tpPLC was created for an old MacOS version, and only runs on Intel hardware. Apple's machines are now ARM chips. My system  is now saying that that support for Intel code on the ARM systems will disappear when the system is updated next.

When this happens I will no longer be able to manage my Powerline network. It should be a simple operation to recompile the tpPLC app to support both Intel and ARM. Sadly, the version of tpPLC for the iPad doesn't support my magic boxes. 

So how do Mac Users get this message into tp-link and get things changed??
