ARD unable to connect

Something you may have already tried but my usual fix for this - not great I know but, over the years, it's the one that reliably works, generally - is to remove the client from the All Computers list and then re-add it. Call it a 'feature' of the application.

Jaydisc,

Thanks for that great suggestion!

I have a client that was having the same issue, saw the similar log entries repeating over and over once 'remote management' check box was ticked ON :

{ com.apple.xpc.launchd[1]: (com.apple.screensharing.agent) Service only ran for 0 seconds. Pushing respawn out by 1 seconds. }

So, amongst other things, I did some internet searching, found your suggestion, and sure enough, reinstalling the ARD Client 3.9.3 did the trick, now it's working all fine again. Quick & Easy & Excellent solution!

I have the same and removing and reinstalling ARD with Kickstart has made no difference.

Maybe there is a better means?

I am not a CLI expert so working out how to use it through ssh means I am very likely missing things others would know about.

I will post more when I fix it, assuming I can find a method.

Having examined the system.log and install.log on the remote Mac - it was clear that the issue commenced right after the OS X Update was completed. From that point on the ARD service is trying to commence but failing to start.... i.e

error message:

Jun 6 12:42:00 DSL-HYB-SVR-001 com.apple.xpc.launchd[1] (com.apple.screensharing.agent): Service only ran for 0 seconds. Pushing respawn out by 1 seconds.

what we did:

download the current version ARD (remotedesktopclient3.9.3.dmg) client software on the local mac ( the so called client software is actually the service, for remote installation)

extract .pkg file from the .dmg file, on a local mac

scp the .pkg file to the remote mac:

$ scp RemoteDesktopClient.pkg 193.234.232.212:

then install the file on the remote machine:

sudo installer -package ./RemoteDesktopClient.pkg -target /Volumes/Macintosh\ HD

then restart the services on the remote machine:

/System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/ki ckstart -deactivate

/System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/ki ckstart -activate

The first thing we learned doing this was that the remote mac can install a package but not a dmg disc image and we did't know how to open the dmg to make the package available remotely.

However, extracting the package locally and then uploading it to the remote mac enabled the installer on the remote mac to run as expected. Yes, ok obvious when you realise this of course.

Secondly remembering that OS X terminal commands are apparently case sensitive.

Many thanks to Tom Yates of http://gatekeeper.ltd.uk/ whose command of the linux command line and general brilliance enabled him to successfully climb into the Apple Garden and get a result for us - so our remote box is now back on vnc.

Cheers, Nick

I am experiencing the same issue. I was unable to install the ARD 3.9.3 client:

"installer: A newer version of this package is already installed."

The client and server are both running High Sierra 10.13.5. I'm running the latest ARD server 3.9 locally.

Only a full reboot of the client seems to get things working again.

I just had the same problem on a cleanly installed 10.11.6 client. Just updated the Client to 3.9.3 and it started working right away.
