I am running a Mac Mini from my iMac using remote desktop which works fine but for the fact that the remote desktop screen refreshes very slowly, sometimes not at al if there is a graphic. Have I overlooked some setting or such? How can I improve the situation?

iMac, OS X Mountain Lion (10.8.4), printer, scanner, ATVs, external hard drives, USB DAC

    Have you tried leaving the display adapter that was included with the computer plugged into the mac mini?

    and or,  do you have the issue when you have a display plugged into the mac mini?



    also how are physically connected to the mac mini? (both computer plugged into ethernet to the same router OR like wifi is some how involved?)

    so if I understand, it's mac mini plugged into router, accessing the mac mini from the ipad or power book from wifi?


    have you tried accessing the mini from the powerbook over ethernet with wifi off on the powerbook?  if so dose it help with your issue?


    I woud suggest try plugging in the display adapter, even if it's not plugged into a dispaly. It can some times tick the mac mini into thinking it has a display plugged in. I've had servers act strange when no display is plugged in, so tricking it to think there is a display plugged in could possible resolve some remoting into issues.

    I have the same problem with the delayed screen. The picture I get just refreshes if I move something (the mouse, a window, etc).

    I have a Mac mini server connected via Ethernet to a router. My remote Mac is also connected via Ethernet to the router.

    All software is the most recent (mountain lion server, mountain lion, Apple Remote Desktop, Apple Remote Desktop client).

    If I connect via Internet to the server, it's the same...

    Has anyone an idea for how I could solve this problem?

    I have the same problem remotely connecting to my MacMini Server. The screen comes up with a big yellow block in the middle of it and I have to move the mouse to reveal the actual screen. I can also go to preferences and changes the scaling of the display to another setting, then changung back to the original setting. Any ideas?

    Same problem.


    ARD 3.6.2 client (running on iMac 27 / i7 / OSX 10.8.4) controls 2 mac-mini's via Internet.


    Controlling Mac Mini i5 with OSX 10.7.5 works fine.


    Controlling Mac Mini i7 with OSX 10.8.4 starts with black screen, the screen freezes up, only refreshed if i move mouse, slow response on keyboard.


    Both Mac Mini's are in the same network. Only 1 mac mini is controlled at the same time.

    1080p screen is plugged in via HDMI.


    Tips, tricks, solution are welcome.


    Note: After purchase of ARD there is a 90 days technical support for free. Problem also reported to Apple, keep you informed.
