There are some work-arounds, and there are some ways to avoid it. I hope this is helpful to another Ham and I've saved them the hours I spent tracking this down.Ĭlick to expand.There are a variety of issues, mostly related to changes in the USB stack made by Apple.
There were prior workarounds but they went out the window with El Capitan. If you later want to re-engage SIP, repeat the steps and use the 'csrutil' argument to 'enable'. However, we you need a work around, which to turn SIP off, which you can do as follows:īoot you Mac to the Recovery System, holding the command R down during boot.Ĭlick the Utilites menu and select Terminal. I totally applaud the addition of SIP to further protect me, that's why I love Apple. The current version of OS X is not tolerant of unsigned drivers now Apple has integrated System Integrity Protection (SIP) to prevent malware attacking users. The issue is the West Mountain drivers are not signed yet. I use an Icom 746Pro with a West Mountain Plug and Play to provide the CIV interface via USB and a virtual serial port. I'm new to using the Mac for logging and radio control and had a fit getting everything to work so I thought I'd post my experience for others.
