Screen Sharing on Yosemite

I tried to get Screen Sharing to work without success today. While on FaceTime with a friend – running also the release build of 10.10 – I tried to establish sharing via iMessage -> Friend Contact-> Details ...

Sometimes a loading bar appeared and vanished again without any dialog.

One time I got an error message:

I then went to my Sharing settings and enabled Screen Sharing.

My questions are:

Do I have to enable "Allow access for: (x) All users" to make Screen Sharing work via the Internet?

Wouldn't that pose a potential security threat?

Same boat!

I'm totally in the same boat here. Ever since upgrading most of my machines (fresh install on one of them), BTMM has been stupendously horrid. I have two machines sitting next to each other on the same network, and they won't show each other, even after doing all the "usual" (toggling the service off and on, deleting BTMM keys in Keychain, etc).

I have six Macs (2 rMBP, 3 Mac Mini, 1 Mac Pro) that I normally need to get to throughout the day, and now I have NO access at all. Even if the machines show up in the Finder window, the connection fails.
 
Back to My Mac/ Screen Sharing is broken for me with Yosemite, where it worked just fine with Mavericks. I am lucky if my remote computer shows up at all in the Sharing list in Finder.

I used to remote desktop from work to my home Mac Mini on a regular basis using my MacBook Pro, both running Mavericks. Since upgrading them both to Yosemite, Screen Sharing is broken. Sometimes I can screen share when I am connected to my home network internally.

My two office machines (iMacs) won't screen share at all since upgrading them but I could log into one of them from home machine (Mac Mini); the office machines don't see the hMac Mini at all, and now none of them will screen share with any other.
 
Yosemite broke BMM on my machines too. :confused: I've done everything to troubleshoot, and still nothing works.
 
Same here hasn't worked sine Yosemite. Tried fresh installs and that did nothing. I have a Time Capsule and Back to my Mac is enabled and shows a green light. I can connect to the Time Capsule from work but can't see half my Macs and when I can, can't connect to them. Same error as the guy above posted.
 
I have 2 headless Mini's at my clinics, one Mavs and one ML and ScreenSharing to either one of those works great now, I connect to them from my Yosemite machine.
A majority of my lag was from settings on my office routers. Changed those and all the employee's immediately noticed quicker all around VPN and internet access.

When I say quicker it was like milliseconds to maybe 1 second quicker but when you use it daily over and over you'll notice a change.
 
Changing the wifi channel fixed it for me...

I changed my wireless routers channel (Time Capsule) (with airport utility) and screen sharing started working on Yosemite -> Yosemite!

That makes little sense to me since BTMM is not a Wifi specific service. In fact, Wifi is turned off on my Mac Mini.

have you tried screen sharing from another network? That is where the service fails to work. I can screen share between computers on my home network all day long, but once I try connecting remotely (e.g. from my office) my Mac Mini at home doesn't even show up.
 
Hi,
I found a way to have a working shortcut in the dock to remote control my mac mini (on yosemite) from my macbook air (on yosemite).

First I had the same issue, when placing the screen sharing application (while connected to the remote imac) , this shortcut was not working.

The solution that worked for me is :

1) Launch Screen sharing application from its original location :
Hard Drive > System > Library > CoreServices > Applications

2) Enter the name of the mac you want to connect to

3) enter the credentials (username and password defined on the remote machine) and SAVE them in the Keychain access .

4) Right clic on the Screen sharing application in the dock (while it is running) then clic on "keep in the dock"

5) Then you'll be able to tun the shortcut in the dock by right clicking on the screen sharing application in the doc then clicking on the remote machine in the list.

Note : when you connect the first time (after a reboot or a session opening for example) you need to hit enter to validate popup box with your credentials, then if you quit and relaunch the screen sharing, the password won't be asked.

Note 2 : when scrolling the display of the remote comxputer (in safari for example) it's very slow , due to adaptative quality selected, if you select full quality, it's ok

Also broken is "Wake On Network" or Wake on Demand services. Clean installs, does not fix it. Sometimes it works on its own and suddenly it stops. Reset AX, changed network channels, change radio channels change names it eventually stops working. It's a shame Apple can't get this straightened out. You can't let the Mac sleep, so it has to run constantly and waste electricity. Here we have Apple touting environmental responsibility yet can't even get this working for millions of Macs. :confused:

How did you resolve it? Are you on 2 or 5 ghz and what radio channel are you using?

I didn't do anything to resolve it. I updated to 10.10.3. What my Wifi freq and channel are is irrelevant, since it varies depending on where I am and what wifi network I attach to.
