This was working just yesterday 8/7, this morning a new Sonoma redwood tree screen saver appears (is it related? uncertain..) and now launching rvictl no longer starts. Running on a 16 GB Mac mini with M1.
Yesterday I happily used Wireshark for debug development, today no longer. Moments ago I went through the process here to enable extensions (which was not required when I initially loaded Wireshark):
Following the process and enabling both checkboxes for user and remote management, I rebooted. Still unable to launch rvictl. One of Quinn's postings included below steps:
sudo launchctl load -w /Library/Apple/System/Library/LaunchDaemons/com.apple.rpmuxd.plist
sudo kextload /Library/Apple/System/Library/Extensions/RemoteVirtualInterface.kext
In the process, a new driver was somehow auto-downloaded from Apple, and upon another requested reboot an "Allow" button appeared when looking at my Systems Settings->Privacy and Security. Reboot again, still no go.
Another Quinn posting said only the first checkbox in the security settings was required. So I rebooted again, unselected the remote management checkbox. Reboot, and still no go. But now invoking rvictl hangs.
There appear to be dozens of forum posts regarding rvictl, many laced with black magic voodoo suggestions to get it running. Eye of newt, toe of frog, wool of bat, and more.
Security it seems becomes the bane of development. At this point, I'm uncertain what to try - though long for yesterday's debug bliss.
