Screen Sharing Failure from Admin 3.72 to Yosemite Clients 3.8

My Yosemite classroom Macs have ARD Version 3.8. My Admin version is 3.72. I can do everything with the clients except share my screen, which I use every day for teaching and demonstrating. I discovered I can still share my screen with the remaining clients using ARD 3.71 or earlier. So, is there a solution, an Admin upgrade or a downgrade available for my clients back to 3.7.1.

I have talked to two of the specialist in the Apple Service Center and they didn't even know this was an issue.

I wanted him to do exactly same environment that I am having in my iMac lab. This guy was keep saying that it is me who is having a network problem. So he was telling me to install Yosemite again. And it did not solve my problem of sharing screen.

The other guy that I talked to was patient enough to do as I have explained. If the Admin was upgraded to Yosemite and clients are still in Mavericks then screen sharing is working just fine. But if you upgrade client computers to Yosemite, then screen sharing is not working as it should be.

It has been already a month now that I told him what I am experiencing, and it is not still solved yet. He told me he was gonna report it to the relevant department. I really need to get things ready before March, otherwise my class will have to go back to the stone age again....... watching on projector screen.....

I'm sure they are aware of the situation, but they do not operate on the schedule of its user base. They try to prefect their products until they perform the way they want and then release it when they are ready to.

I'd recommend that in the mean time you guys find alternative options, like reflector*. It only shares to one screen at a time, but might help one of you.

You could also try something like streaming from the popular tube of you*, sharing your monitor to a live channel that students could connect to and view from multiple computers.

I'm just saying you shouldn't wait up for apple engineering... don't call them, they'll call you...*=not allowed to post third party company names or products

Ok I got a workaround working on my test machine. Unfortunately you'll need access to a mac running ARD client 3.7.1 (OS X 10.9.5).


Simply swap the RemoteManagment folder containing the ARDAgent 3.7.1 from your Mavericks Mac (/System/Library/CoreServices/RemoteManagment) to the same location on the Yosemite Mac. I went ahead and renamed the Yosemite RemoteManagement folder to RemoteManagement38 just to keep the 3.8 version around.


I'm only able to share my admin screen to one test mac. I won't be able to try it out in my larger lab (17 macs) until this weekend. But for those of you who are in my boat. It's worth a shot.


Good luck.

You are truly a genius Tonicism. This worked in my lab with 32 computers. I agree with the other comments posted here. I called apple many times regarding this issue and they could never solve it, telling me a fix will come on the next update. 3 months later and I'm still waiting. Thanks to you however, this has finally been fixed and I can now upgrade all my machines to Yosemite.


I know this is not the topic on this forum, but does anyone know how to work on mac server running yosemite. Everything is working fine, except that users are not getting a prompt to change their passwords after I check the option for them to change it on first login.
