Double monitors Mac Mini issues

Recently I performed a clean installation of 10.11.6 on my Mac Mini end of 2012, and now all of a sudden when I restart in normal mode with two monitors Hung (one bolt of lightning, the other HDMI) he logo apple, loads, then everything goes black. If it is plugged in, it loads the main office very well. If I load in safe mode, I can start with two monitors very well. Also, if I boot boot with a plugged in, wait for loading, then plug the second, it works fine.

Before the installation of the OS, these two monitors worked fine without having to do that, running the same hardware and OS. Super boring... I'd appreciate any help or advice! Thank you in advance.

  • iMessage on iPhone, iPad and Mac Mini issues

    So, here's a nice.

    Mac Mini, iPad Mini, iPhone5. All are on the latest versions of the OS. Connected to the identical services iCloud and iTunes on all three devices. The iPhone 5 is delivered to US, the others are the European Union (NL) issued.

    When I send an iMessage on the phone, the message sent is not the Mac Mini or Mini iPad. sent iMessages to iPad or Mac appear on both devices, but not on the phone.

    Incoming messages only appear on the phone, not on the other two aircraft.

    People receiving my messages of either the Mac Mini - combo of the iPad and the iPhone5, have two separate conversations in their messages, but an entry from me in their list of contacts.

    In iCloud online, all devices can be considered to be connected with the same account. All have been disconnected from iCloud, password has been changed and reconnected. All devices were restarted. All to nothing does not.

    Other services such as calendar function without any problem at all, an appointment has been made on what devices instantly extends to the two other devices. New contacts are shared between all the devices too. If the problem is limited to the iMessage.

    In short, I suspect there is a difference between EU and devices of the American unit, preventing them to be treated equally. Does anyone else have this problem or something similar?

    Hello mackert,.

    Thank you for using communities Support from Apple. I know that Messages does not properly or sync with your devices is not what you expect. Based on what you said, it seems that you encounter some problems of synchronization with connected devices to your Apple for message ID. Good news is I had this problem myself and I solved this problem by following these steps:

    1. Firstly, you disconnect from your Apple ID for iMessage on all your devices. On your iOS devices, go to settings > Messages > Send and receive and sign for your Apple ID. Then go to settings > Messages and turn off of iMessage.

    2. on your Mac Mini, open messages, then go to the Messages menu > Preferences > accounts. Click your iMessage account in the left sidebar, and then click Sign Out and then sign out again.

    3. restart your devices as closing down and starting process is important to keep the software works correctly:

    Restart your iPhone, iPad or iPod touch

    How to turn on or off your Mac

    4. now sign in iMessage on your iPhone first. Go to settings > Messages, turn on iMessage and connect you to your Apple ID in settings > Messages > Send and receive. Make sure that you are successfully connected, iMessage is activated, and you see your phone number and e-mail available for both "you are reachable by iMessage to ' and"Start new conversations." That's because iMessage uses your iPhone SMS to activate iMessage on your Apple ID.

    If you get an error when you try to activate FaceTime or iMessage

    5. Once your iPhone has configuration iMessage, then sign into your other accounts and check the synchronization of Messages. You can also turn on "Text Message Forwarding" under settings > Messages on your iPhone to better ensure that all devices have the same messages.

  • Mac Mini issues

    We have 6 iMac in an Ethernet network. We are looking to replace with a MacMini. I have some questions:

    1. Is there a new MacMini since end of 2014 or is it the last? Apple intends to continue offering the MacMini?
    2. A connectable MacMini to an older iMac for its display?  Alternatively, a single view option would be necessary - another monitor?
    3. It does not resemble the willing MacMini to an Ethernet port?  Is there a model that makes?  Otherwise, what is a solution to integrate a Mini in an Ethernet network?
    4. MacMini is a good option to use as a server for enterprise applications we are using an accounting program Explorer, office and some Adobe products as a server.

    I think that's all... Any suggestions, warnings, knowledge, experience in the answers is welcomed.

    Thank you.

    1 October 2014 is the current version. No reason to think they will stop him offering.  But no way to know what Apple plans would be for her in the future.

  • Use two monitors on Mac Mini end of 2012

    Hello

    I am currently using only a single monitor (A Dell S2340M 23 "") with my Mac Mini end of 2012 (with these ports: Mac mini (end of 2012): external ports and connectors - Apple Support), and I am interested in adding a second monitor, something around the same size as my current. How to connect two monitors on my Mac? Thanks in advance.

    The support for the Mac Mini shows article (end of 2012) and details which ports can do.

    So you would probably need to get an adapter Thunderbolt using a second screen, seems.

    See the items listed to connect to the Thunderbolt port in the link you posted. I have the same

    link to my favorites for more than a year...

    I have an i7 Mac Mini end of 2012, using only a screen Apple Cinema (aluminium).

    Another option would also buy a bolt of lightning multiple port dock. Some allow others

    products and ports in double. (Upward to 12 points, USB3.0, Thundebolt, etc) not cheap. A

    A few screens can allow a Garland; Note looks like a bolt of lightning MiniDisplay port but can

    not act like one. Adapters can allow minidisplay run Thunderbolt. See supported

    Article and then see the page of the Apple store in graphics cards.

    OWC has also an external optical drive with several ports integrated (with additional HARD disk).

  • I have an old Mac Mini with a DVI Port that came with a VGA DVI-adapter.  Tonight, my monitor went down.  Brand new monitor works with that?  Can I use an adapter?  If yes should which adapter I?

    I have an old Mac Mini with a DVI Port that came with a VGA DVI-adapter.  Tonight, my monitor went down.  Brand new monitor works with that? Any recommendations? Can I use an adapter?  If yes should which adapter I?

    You can use any DVI monitor DVI port directly or have any VGA monitor with the power that you adapter. A HDMI monitor might work with an adapter DVI to HDMI in a pinch, but HDMI tends to be more fickle.

  • My Mac Mini (end of 2012) will support a MHL HDMI 4 k monitor?

    Hi all..

    I'm a little confused about two things.  I'm in the market for a new monitor and thought getting a screen of 4K, but I came across 2 questions...

    1 - is my Mac Mini w / 1.5 GB HD4000 support a MHL HDMI monitor? (I know that my current monitor is connected via HDMI and it works fine but "MHL" in the face of the HDMI throws me for some confusion.  My HD4000 graphics card is able to use the display 4K?

    2. If this type of connector would I need to do 4 K monitor work?  A standard HDMI cable would make the case, or do I me some sort of DVI (or something) connection cable?

    All information of someone a little more familiar with it, so I'm would be great because it's what makes my decision to purchase between a nice 144 mhz Full HD 27 "monitor of game and an Ultra 4K 28" monitor.  I'm more concerned about the view regarding the use of photoshop and dreamweaver even more than games, but a combination of the two would be a nice touch.  I know that the first works, but something is lure me in get the screen 4K of supreme graphics in applications like Photoshop.

    Thanks in advance!

    1. the 2012 Mac Mini is not capable of producing at 4 K resolution, unfortunately. It is limited to a maximum of 2560 x 1600 on the Thunderbolt Port / Mini Display Port.

    This means however not she can use the 4 k display, it can, just that it will be at the lower resolution, the mini can produce.  The 4K display can always make things a bit pretty but.

    2. you must use a Mini Display Port to DVI (assuming that the 4 k display has a DVI port) to get the highest possible resolution of her. 2560 x 1600

    Note that HDMI port is limited to 1920 x 1200 pixels

  • Can the iPad will be the single monitor to a Mac Mini?

    For the most part, everything we do on the computer can be done with the iPad. However, there are some applications for which we need a computer that is running something other than iOS. What we have is for each family member to have an iPad, that would work for 95% of what we do and then have a Mac Mini that anyone can use for applications that do not work on an iPad. We really don't want children using a MacBook, because they are too fragile, and we do not want a monitor constantly sitting around the House. I saw a software that will transform the iPad into a monitor for the Mac Mini. Can this work as the single monitor? I consider the MacMini sitting quietly somewhere in the House, so that each of us could 'plug in' (either wireless or wired, not sure how it works) to him with an iPad when it takes more computing power. The MacMini would never be used with anything other than an iPad as a monitor. Is this possible? Thank you!

    There are apps like the Team Viewer free (for non-commercial use) and the paid LogMeIn and the GoToMyPC that allows an iPad control/use a computer...

  • HP w2207h monitor: HP monitor crashes if connected to the Mac Mini

    My w2207h monitor works fine connected to 2 computers. A Dell laptop connected with a cable HDMI and a Fujitsu PC connected with VGA cable. I spend between the 2 with the menu key of monitors and the function 'change the video input '. However, I just buy a Mac Mini and connected via HDMI but now, pass the VGA to HDMI causes the monitor to crash/power down. Even the light around the power button goes off and nothing works. To relight the monior screen, the only way is to disconnect the cable from power for a few minutes. The monitor works with an another old laptop connected via HDMI as doeas the Mac Mini connected to an old television set. I thought HDMI HDMI was, but this monior dislikes my Mac. Any ideas?

    Thanks for the information Dunidar. A long session, running tests with Apple confirmed that this monitor does not work with Mac Mini. The only solution was to buy a new monitor :-(

  • You can use old iMac as a monitor for mini Mac

    You can use 2008 iMac as a monitor for mini Mac?

    No, because the iMac of 2008 not display entered or supported to do so.

    See > use your iMac as a display with the target - Apple Support Display Mode

    You can use a connection network and something like ScreenRecycler

    See > https://www.screenrecycler.com/ScreenRecycler.html

    However, the best bet is to use a regular external monitor with the Mac Mini.

  • Anyone WHO is running 2 monitors from lightning on a Mac Mini (Windows 7)?

    Did someone drive actually two screens Thunderbolt out of a Mac Mini (late 2014, complete the form below) in bootcamp with Windows 7?  Apple says you can do (see below), I couldn't, and I'm pretty technically competent.  Windows 7 in Bootcamp runs absolutely perfectly, I used all the latest drivers and drivers from Bootcamp OK/set of tools for my machine (Apple publishes sets of specific tools for each machine).  Windows just absolutely does not see the second monitor Thunderbolt, I went through each option of control panel in Windows 7.  To do this, of course, works very well under OS X.  I am currently using Parallels to work around the problem, but the decline in performance is much too tight, and I need to run Windows directly in the training camp with two monitors.  Help, please.

    I understand that the image quality for your HP monitor is poor when connected to your Mac Mini, and I'd be happy to help you in this case!

    According to this document on the use of Monitors HP on a Mac:

    "The HP monitors are not supported in a Mac environment. However, recent Macs use graphics with VESA modes and can display most of the HP LCD monitors. To do this, connect the monitor to the Mac, while the Mac is turned off and then turn on Mac. The monitor must operate at 60 Hz. The INF and software for the HP monitor are for Microsoft Windows and cannot be run in a standard MAC OS environment. »
