I'm trying to inspect network traffic on an iphone 11 pro, I use:

rvictl -s [UDID]

on terminal and it closes after a couple seconds without any error. I know the UDID is correct because if I use a wrong one it brings up the help . I installed most of the extra tools I found for xcode and such and rvictl is available, it just doesnt work.

This issue (81125115) was fixed in Xcode 13.0 (13A233).

Disabling SIP as a workaround is no longer needed, so I recommend enabling SIP (check with csrutil status).

For Apple Silicon Macs, the Reduced Security policy "Allow user management of kernel extensions from identified developers" is still needed, instructions here.

Same situation here, it seems rvictl needs to be updated for big sur.

Have any of you found a solution? I am having the same problem right now.

Using: macOS 11.0 (Beta) and iOS 14.1

rvictl works for me in Big Sur 11.0.1 (20B29) with Xcode 12.2 (12B45b) after I loaded rpmuxd as described here.

The path to rpmuxd's launchd plist may differ from the path in that article. I used this command to load it:

Code Block 
sudo launchctl load -w /Library/Apple/System/Library/LaunchDaemons/com.apple.rpmuxd.plist

Pb still present ...
Using MacOS beta 11.1 (20C5048k) with iphone X11 pro iOS 14.3 (18C5054c)
rpmuxd is loaded and outputs the same expected message on the mac console each time I run rvictl -l :
com.apple.rpmuxd:rpmuxdgetcurrent_devices:847 No devices currently available

However, when running rvictl -s UDID, nothing happens : I get the prompt back a few seconds later, there is no error nor success message.
And nothing obvious in the console ...

Can anybody help ?

PS : I tried UDID lowercase and uppercase, same issue

so sad about it.
No action when it run with the -s flag, and with -l it reply with Could not get list of devices

I was having the issue with rvictl refer responding, but now I am getting the FAILED error. Updated to latest Xcode 12.3 (12C33) and macOS 11.1 (20C69) and iOS 14.3 (18C66):
Code Block language
# sudo rvictl -s 00008101-<REDACTED>
Starting device 00008101-<REDACTED> [FAILED]

Same happens with and without sudo...

Same here on iOS 14.4, macOS 11.1 and Xcode 12.4

When the UDID is copy pasted with all caps I get 
Code Block 
Starting device <My UDID> [FAILED]


For a laugh I tried changing the letters to lower-case and get no stdout, also tried -l and -L after each and "Could not get list of devices"

I'm just starting out on Apple development so I might've missed something though...

Edit: I've tried with and without sudo

Any news about it? It's not working and I can't find a solution yet.

Folks, I solved doing this:

as root:

installer -pkg /Applications/Xcode.app/Contents/Resources/Packages/MobileDeviceDevelopment.pkg -target /

After that in uppercase:

rvictl -s UUID (it will open to you change the preferences of your systems and reboot)

After restart, everything fine over here.

Hope that help you folks

Seems to work after running sudo launchctl load -w /Library/Apple/System/Library/LaunchDaemons/com.apple.rpmuxd.plist, although the response to this command was:

/Library/Apple/System/Library/LaunchDaemons/com.apple.rpmuxd.plist: service already loaded

The next time I ran rvictl -s UUID:

Starting device UUID [SUCCEEDED] with interface rvi0

I have tried all of the solutions in this thread, but I am still getting a failure when I try to start a device with rvictl on an M1 Mac mini running Big Sur 11.2.3 and Xcode 12.4. Any help would be appreciated!

By the way, if anyone is trying this on a Mac M1 (apple silicon) and rvictl says FAILED, its because you need to enable mac system extensions - https://support.apple.com/guide/mac-help/change-startup-disk-security-settings-a-mac-mchl768f7291/mac - basically say "reduced security" and check all the freaking boxes that say enable kernel extensions and all that. And after you bootup, you have to again go to system--->security&preferences and there will be an "allow" button you have to click there which will again make you reboot.

I wasted freaking a day on this crap and finally after lot of browsing I figured thats the reason. I enabled system extensions and its working fine

basically say "reduced security"

Correct.

check all the freaking boxes that say enable kernel extensions

Not quite. Of the two checkboxes, you only need to check “Allow user management of kernel extensions from identified developers”.

And yes, I agree, this is seriously suboptimal. I had a chat with the RVI folks about this situation and I’m sad to report that this is the only way to get RVI working on Apple silicon. We have a bug on file about this (r. 78015664) but, as per usual, I can’t comment as to when we’ll see any improvements.

Share and Enjoy

And yes, I agree, this is seriously suboptimal. 

@eskimo, my frustration was not about having to enable the kernel extension - that took me < 5 mins and thats perfectly acceptable to me. My frustration was that rvictl FAILEd as a google search did not lead to any help page or anything, what it led to was this thread with potpourri of random suggestions. I am not kidding when I said I wasted a WHOLE DAY (at least) on this - I even thought that its probably that my ipad (attached to my mac mini) is too old and hence I drove one hour up and down to an apple store and got a new one, only to see that had the same issue. Then I kept at google searches till some kind soul somewhere had hinted about having to enable kernel extensions.

So my point was that along with rvictl FAILEd, if there was one more line of message that said "please enable kernel extensions", that would have made my experience with apple development far more smoother

I have enabled kernel extensions and reduce security ,but rvictl still failed

Same problem here. Running on M1, Xcode 12.5, iOS 12.0 Beta (21A5248p).

Now I don't know if it has to do with me being on the new beta build of iOS or not.

The error I get in /var/log/system.log

Jun 18 11:47:39 Nickis-MBP rpmuxd[12518]: com.apple.rpmuxd:rpmuxd_start_kernelctl:234 Child process /sbin/kextload[12519] exited with status 29

I tried everything that is mentioned up till now, but sadly with no good result.

Another issue is that

rvictl -L   or rvictl -l

returns

Could not get list of devices

Fortunately: ifconfig -l gives a list but rvictl fails to connect.

Doesn't work for me either. Always receiving

Starting device 00008030-<redacted> [FAILED]

macOS 11.4

Xcode 12.5, also tried with the rvictl bundled in Xcode 13 beta 2

MacBook Pro 15-inch 2018

Restarting the MacBook / iPhone didn't help. Would be great if rvictl could give a hint why it is failing. Wasted hours on this topic.
