Why is Remote Management and screen sharing now very slow between two MacBook Pros running Yosemite?

Thumbs up to macminicolo also! This fixed my issue between iMac and Mac Mini. The mini was hooked to wall displays through HDMI and DVI-HDMI converter, but when the screens are off its slow as the devil. Turning on the screen works too.

The same happens to me when remotely managing a Mac Mini Yosemite from my Mavericks iMac 27".

Take in consideration, please, that "remotely" means 20 feet on a perfectly working WiFi network

The same on Ethernet cable 😟

BTW speed was at the top, when Mac Mini was running Mavericks 😟 😟

No other Macs on hands in order to perform comparative tests!

Any thoughts?

Systems Configuration

==================

• iMac 27"

OSX 10.9.5

Screen Sharing Prefs:

- Display: Show Full Size

- Quality: Adapt to network conditions

• Mac Mini

OSX 10.10

Please add me to te list guys.

Both my Mac Pro 2008 and Mac Mini 2014 are connected on GB Ethernet. The screen sharing is slower than a snail (not speaking about all visual/drawing bugs on the monitored screen). I've tested with a MacBook Pro too, same deal.

That's really suck.

My solution is to use the chrome remote sharing application but boy do I miss simple screen share.

Bump!

And, add me to the strangely small list of folks having this problem. I have a small island of Macs to support in a sea of PC's. VNC remote is the only way I have to manage them without having to jog my 250 lb butt all the way across the company campus. (not that the exercise wouldn't do me good)

Try changing: View: from "Adaptive Quality" to "Full Quality."

That doesn't make one bit of difference. For me the screen sharing works for about five or ten minutes without problems, then gets laggy and unusable. Only solution I have found so far is to close the screen sharing window, then open it up again from the Finder. PITA but that's the only thing that works so far, for five or ten minutes... Hoping that Apple will fix this soon.

Running 10.10.1 on both machines. One is a mid 2011 27" iMac and the other a late 2013 MacBook Pro 15".

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Feedback

Thanks Eric, that's what I just did. Good to have a feedback page for future reference!

I also just submitted feedback for this bug. I hope it gets addressed soon. Extremely slow screen sharing performance here since upgrading to Yosemite.

And another one....

Under Mavericks and below using the built-in Screen Sharing app (hidden the the System/Library/Core Services/Applications folder for some unknown reason), I could almost instantly connect to other Macs on my network AND across the internet with know IP addresses. It worked PERFECTLY.

As soon as I upgraded to Yosemite, remote connections take up to a minute or more to connect (if at all). Though once connected, it still works pretty well.

It just takes way too long to connect, and fails about half the time.

Closing the screen sharing and opening again was the only solution that worked so far. I also submitted the feedback for this bug.

Add me to the list of people experiencing this issue in Yosemite. (Leopard and Snow Leopard worked just fine.) Hope this gets addressed soon. Getting tired of issues such as these. And it seems like with each new OS they take more away than they add. Or introduce bugs (like this one) that were never there before.
