RealVNC with Quad Core Mac Mini "Refresh Issues"

Upgraded my Mac Mini server from a dual core to Quad Core machine.  Headless machine, hence used RealVNC to administrator it.  So when I utilised RealVNC, connecting via an ipad and the quad core machine had "Refresh Issues"!!  Went back to the Dual Core machine and you can view everything in real-time!  Can't explain it and the RealVNC people can't understand it either, yet!!!???

It has a wired ethernet connection, the wireless is on but more for "location" services.  And no USB 2.0 or 3.0 devices attached, in fact it's headless, and only the power and ethernet connection attached.  But interesting to learn of the wireless issues on the new mini's.  Thanks!

  • Jagged wavy lines edge of CRT display with Dual Core Mac mini

    My friend recently bought a Dual Core Intel Mac mini and when hooking it up to a 19 inch MAG monitor there are often wavy lines on the edges of the screen. They go up and down both sides, are jagged, and also are not static but moving quickly. Sometimes it seems to behave normally while other times if it doesn't show up on the boot screen it will show up after a little bit of use.
    At first it seems that the more stuff I opened the worse it got, so I thought it could be the shared video RAM as he did not upgrade from the original 512 , but that should only slow the computer down anyway. Now I think rather than the RAM I think it could be related to the Apple DVI to VGA adapter, resloution/refresh rate, or just bad video hardware. I can't rule out that it just won't play nice with the majority of CRT monitors out there either. Sometimes changing the resolution/refresh rate helps and other time it doesn't. From what I heard my friend experienced wavy lines somewhat on his own monitor but I don't think it did it when using a DVI to HDMI cable to his Sony 50 LCD (and I didn't see it when hooking it up to mine either).
    If anyone has any idea what could be going on I would greatly appreciate it. The reason it is so important is that my friend decided that the Mac mini was kind of an impulse buy and didn't need his iBook and another computer for his TV so he is going to sell it to my brother who is in need of a computer. So I don't want him to get into something that will give him problems right away.
    Thanks in advance,
    Robert

    So is the MAG monitor your brother's monitor? That wasn't clear.
    What you are seeing will most likely be limited to the MAG monitor. The MAG is experiencing some kind of noise coupling in to horizontal sync, likely from it's own power supply. You are correct that this will be related to the sync rate. Changing the vertical refresh to something higher, like 85 Hz or higher if available, might help to mask the noise. Also, power supply loading will affect how the noise manifests, so you weren't imagining when you thought that opening more applications made it worse. It didn't have anything to do with the mini but rather the different average picture level on the screen was changing the monitor's power supply loading and hence changing the beat frequency between hsync and the power supply's switching frequency.
    I think it is safe to say most of what you see is bound to the monitor and not the mini. Furthermore, if you are stuck with this monitor, you can probably lessen the appearance of the noise by mucking with the refresh rate out of the mini.

  • X320 with Quad Core / IPS (no screen issues / throttling this time)

    Make it happen Lenovo.
    Shut up and take my money.

    the one RED light that stays on is on the top of the 4 LED lights inside above the power button on the left . It stays on constantly even after I shut down the computer . now in order to shut down I have to do a manual shut down every time and at start up it will not recognize the optical drive and I believe the fans only run at a very low rate and the LED on the processor tray stays light while the computer is on and running or atleast what appears to be a state of running with absolutle no picture at all now .is it the motherboard or the processor can anyone tell me which way to go .

    I think there might be information there on how to reset Time Machine to do a full backup. I think you basically have to reset it and start over.

  • Mac mini having issues with system preferences retaining settings

    Mac mini having issues with system preferences retaining settings; this was present with Mavericks and now Yosemite after installation.  Did try removing com.apple.systemprefs.plist file (library/preferences folder) to trash, but couldn't find it in trash in order to empty it.  Upon reboot the file is still missing.  Please don't suggest reloading Yosemite, have very slow internet connection, Yosemite took 7-8 hours to D/L.
    Any troubleshooting suggestions out there?  thanks

  • HDTV acting up with late '09 Mac Mini - display prefs at issue

    I used my 46" Sharp Aquos successfully with my 2006 Mac Mini before I gave it to my brother last December and got a new Mac Mini. They were connected with an HDMI-DVI cable from one of the TV's HDMI ports via an HDMI-DVI cable to the mini-DVI port through the adapter.
    Three times this morning within 20 minutes of turning on the TV the TV has turned itself off (the audible click that occurs when the TV is turned on or off and the two green lights go off). The TV turns itself off in a few seconds.
    I contacted a Sharp Aquos person online who gave me a case # and told me to call Sharp on the phone so they could walk me through a factory reset.
    When I got Sharp on the phone they asked me what preferences from the manual's chart I had chosen. I told them that it was my understanding that Macs do this automatically. I checked my display prefs and they're "1080p" (the manual's chart has only vertical and horizontal resolutions) and the profile is set to "SHARP HDMI". Are these prefs OK and thus the Mac Mini not at fault in all this?

    Correction: I meant to write :The TV turns itself BACK ON in a few seconds

  • Will a external Apple iSight work with the latest Mac Mini?

    with a firewire 400-800 if it will what software do i need to take pictures and videos.
    Many Thanks

    Will a external apple isight work with the latest mac mini.
    Yes (if the external iSight works.)
    External iSights are great webcams, but they are getting old (as consumer electronics go) and some have had pretty rough treatment. You can test yours using the suggestions from this page:
      http://www.ralphjohns.co.uk/EZJim/EZJimpage4.html
    I suggest you disconnect other Firewire devices until you get your external iSight working with your mini.
    If you do not already have an external iSight and are considering buying one now,
    a new webcam (with warranty) may be a better choice.
    Many available alternatives are listed here: http://www.mac-compatible-web-cam.com/

    Use one of the following ways to connect your FW400 external iSight to a FW800 Mac port:
    • To use the FW400 6pin-6pin cable that comes with iSight, you can use a 6pin-9pin adapter
      like one of these:

    • Some report that this low-priced alternative cable works:
      http://www.newegg.com/Product/Product.aspx?Item=N82E16812189097
    I suggest you disconnect other Firewire devices until you get external iSight working with your mini. Once iSight works when it is the only FW connected device, you can try connecting other Firewire devices to determine whehter you can use any of them without conflict.
    ... if it will what software do i need to take pictures and videos.
    With your 10.6.3 mini, you can use QuickTime X, iChat, Photo Booth, iMovie, and some of the other apps that are installed with OS X. Your Mac's Help for each of these apps can tell you how to use them with iSight (or other connected cameras.)
    Some more apps you can use are shown in this list:

    The web links for each app gives details on what functions is offers with your webcam.

  • Using An ASD LCD display with a new Mac Mini

    I want to utilize a 17" Apple Studio Display with my new Mac Mini.
    Does HDMI support the 35-pin Apple Display Connector (ADC)?
    It would require an adapter with female 35-pin on one side and a male HDMI (DVI) on the other. The Apple DVI to ADC adapter doesn't work with the Mac Mini HDMI port.
    If two adapters are needed they must have the correct gender connections.
    Thanks.

    Your correct, you would need an Apple DVI to ADC adapter, And ether mini display port to DVI OR HDMI to DVI adapter. (just a question of witch port you want to use)
    Apple DVI to ADC adapter when they were first released cost about 120; now they're kind of rare and harder to find. Online they can go for 200 dollars. so 120 to 200 dollars to make your display work; and displays don't last for ever they have parts that will break down. Older displays have a light bulb inside them; witch burn out just like all the other light bulbs in your house.
    Also DVI to ADC adapters can some times give you blurry images and or text.
    For 120 dollars you can buy a generic brand 19" LCD. That 19" LCD would have better contrast ratio, brightness, and refresh rate then the old 17" monitor. (and it would have a warranty) Or for 200 dollars you could buy 23" monitor.

  • Can you help with a TV / Mac mini configuration?

    So.... the plan is to buy a new 32-40 inch TV for the bedroom upstairs. All of my TV cables and Internet stuff are at the basement. I am not planning to bring any cables upstairs (TV or Ethernet) so this is what I am thinking:
    - HDTV 32-40 inch
    - Powerline to bring network connectivity upstairs
    - Slingbox PRO-HD
    - Mac mini to use SlingPlayer, Hulu, iTunes, DVD Player etc. etc.
    - One of those Air Mice
    These are the questions I have:
    1) The HDMI on the new Mac mini transfers sound as well as video. Correct? No need for extra adaptor?
    2) Can some suggest a good Air Mouse that works well with the new Mac mini?
    3) Anything I need to make sure the TV is capable in order to work well with the Mac mini (except of course for the HDMI port)? Resolution? Other ports? Options?
    4) Anyone with a similar configuration? Any issues that you might see with this configuration?
    Thanks

    I cannot answer any of your other questions, but, yes, the Mid 2010 Mac mini carries both a digital audio and video signal from the HDMI port.
    Sorry, what is an air mouse?

  • Mac Mini boot issue after reinstalling original RAM

    Hi,
    So i am having issues with my 2012 Mac Mini i5 with 4gb of RAM(2x2Gb).  I wanted to upgrade my RAM and unfortunately i keep getting stuck at the Apple logo screen with the progress/loading bar.  The bar gets up to around 40-50% and then my mini just shuts down. So one fix action i took was to reinstall the original RAM, nope that didn't do it.  Next i reset the PRAM and same issue, I am stuck now and have no idea what to do next short of tossing this thing off the building.  as you can see its a bit frustrating, so any and all help would be very much appreciated. Thank you

  • Using External Boot Drive with New Intel Mac Mini

    I have a 1st Gen MacMini and use an external 7200 RPM Lacie drive as the system boot drive along with all the applications.
    If I were to purchase a new Intel Mac Mini, is it possible to use the current external drive as the system drive or is there some conversion steps that would be necessary ?
    Thank you.

    You can use the hardware, but will have to repartition and reinstall the OS from the disk shipped with the new Mac Mini.
    http://docs.info.apple.com/article.html?artnum=303220
    If you create a disk image of the Lacie on your Mini, you can later use setup assistant to restore users and applications from that image.
