Q: Apple Remote Desktop not working

Hi

I have had the same problem. I can confirm that the described fix also works on a desktop computer with dual monitors. I have to have the Remote Desktop window on Monitor 1 to be able to connect to client computers.

Interestingly, my workaround to the scaling error was to use the Screensharing app located in CoreServices before I knew of this fix. It was not affected at all.

Also if the computer was restarted, the first time Remote Desktop was used with the window in the second monitor, you could connect to a client but if you disconnectled and tried to connect again to the same client or another client, the scaling error would appear.

Thanks for finding the workaround fix!

Kind regards

Michael

Has any one figured out how to script the disable "remote management" in system preferences > sharing and then re-enable it?  I have many machines this needs done on.

This has solved my El Capitan upgrades but i have to have the end user with admin rights be able to do this before I can connect again.

This is definitely an issue Apple should help with since it broke because of the upgrade.

Unfortunately Logmein is not an option and neither is teamviewer at this customer's location.

Still looking to automate without end user interaction, APPLE.  You broke it, you need to fix it!

I have too had so many problems with El Capitan, l lost count.  One of them is the same ARD issue listed here.  I'm not sure if it's worth the time to troubleshoot.  There are so many bugs in El Capitan that even their support team is completely lost (I wasted 7 hours on the phone). My guess is that fixing ARD bugs is at the bottom of the list.

On a side note, I had to do clean install of El Capitan on my MacBook Air just to get my system preferences to work (It hung every time I launched).  Unfortunately, the clean install didn't fix my ARD issue.  I still can't connect to my MacMin running El Capitan.  Only my Yosemite Macs will connect. 

I'm now using TeamViewer.  It doesn't contain all the functionality, but it's rock solid when it comes to reliability. 

#El Capitan is worse than Windows Vista.

Extremely frustrated. Stopped rolling El Capitan because of this remote desktop issue. Disable/enable in sharing doesn't work. Using on a primary monitor doesn't work. This is not enterprise grade.

Just upgraded my Mac Pro to El Cap. today. I waited and waited, expecting all the initial problems to have been patched by now. Well... Immediately hit the 'Remote Desktop just says "Connecting..."' issue.

Moved the Remote Desktop computer list window to my main monitor and it started working.

Unbelievable... How does someone even write an app that doesn't work on a non-primary monitor?

I guess this would also result if there was no display connected to a [headless] Mac Pro ... and OSX does that 'I cant know what display I have' thing it likes to do occasionally?

Hello Everyone,         

     I have scoured the internet for a solution that I can not seem to locate. I have about 500 iMacs in my school. 95 percent are wired on the ethernet and some are wireless. I have 10.9 clients and 10.11 clients. I can administer 10.9 clients without a problem. My 10.11 clients whenever I try to remote into them I get a error that states Screen sharing is not enabled... I can not enable screen sharing when Remote Management is enabled. It is becoming a real nuisance not having ARD on all of my computer given the fact I can not install 10.9 on the newer iMacs. I've tired various things. Any help at this point is greatly appreciated. Thank you.

Sorry for replying to this old thread but maybe someone is searching exacly THIS like me :-)

You should think about a unix shell tool like csshX (install via brew or MacPorts) which enables you to do this on many machines at the same time!

## Disable ARD

sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -deactivate -configure -access -off

## Enable ARD for admin

sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -activate -configure -access -on -users admin -privs -all -restart -agent -menu

By the way: That didn't help my with my problem: I'm able to connect via ARD from 10.8.5 to 10.11 but I can NOT send a unix command ("Remote desktop client is not active") :-P      No idea about that... :-(

Best regards...

I've noticed a similar issue after upgrading a couple of our MacBooks to 10.11. This is why I prefer to re-image rather than perform a direct upgrade. The only way to permanently fix it, in my findings, is to re-image. I could not get the the solutions below to work.

As a temporary workaround, disabling then re-enabling Apple Remote Desktop Management in System Preferences -> Sharing on the client machine, resolves the issue. You can invoke a disable/re-enable by issuing the following command via ARD:

#!/bin/sh

sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -deactivate

sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -activate

we've found after updating to El Cap, remote management needs toggling on all clients. We use this command line to sort it

kick="/System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resour ces/kickstart";$kick -deactivate; $kick -activate
