Mac Mini 2009 not recognizing second display

I have a Mac Mini (late 2009) and I have connected two monitors via a VGA splitter. Both screens are working and displaying the image of the screen, but I want an extended desktop and when I try to change the display preferences it says "the arrangements pane has been hidden because you only have one monitor connected". Detect displays does not work, and neither does restarting the computer/turning screens on and off. Help!

Hi, a spitter won't work for this, it simply "splits" a single signal out to monitors for mirroring, the splitter look like one monitor to the computer.
Which port do you have it/them connected to now?

Mac Mini does not detect DVI display on startup

Okay, I have a Pre 2009 Mac Mini 2Ghz Core 2 Duo. My monitor is a Westinghouse Digital LCM-22w3. The display is hooked up through DVI. When I start or restart the mac, it seems that it does not detect the display is plugged in. I have to wait for OS X to finish booting to either put the mac to sleep and bring it out of sleep or unplug the DVI cable and plug it back in to get the display on. If I hook the display via VGA using the VGA to DVI converter there is no problem. I have tried resetting the NVRAM but that does not fix the problem. I would like to get this fixed so I don't have to switch cables to be able to boot my boot camp windows install. Any help is appreciated. Thanks!

Following some investigations the problem appears to be with the power saving features of the monitor.
The MAC mini knows that the monitor is connected but the monitor puts itself to sleep.
The problem appears only when you use a single link DVI-D cable.
These are the ones with two blocks of nine pins with one large blade.
If you use a Dual link DVI-D cable (twenty four pins and one blade) the problem resolves itself and the display is active from power on.
It looks like the mini or the monitor is using one of the pins from the middle block of six for some reason.
Anyway, good look with this, I had a couple of spare DVI cables from when I was trying to get my original G4 mini working with my TV.

Mac Mini will not keep mirror displays on after computer sleeps or shuts down.

Hello. I work in a school district that has a few Mac Mini computers set up with its own moniter and also plugged in HDMI to a projector. Last year we had them set up with OSX 10.6 and decided to upgrade them to 10.8 After the upgrade, Display Mirroring will not stay on. If the computer is reset or falls asleep it is set back to extended desktop. How can I get it to stay without having them constantly turning it back on? (The teachers are using network accounts. I doubt it has anything to do with it because it worked fine last year on 10.6. But I thought I would mention it.)

Does it only do it for network accounts?
Is there an admin account on the Mini to test with?

New Mac Mini/OSX not recognizing Apple extended keyboard

I recently purchased a new Mac Mini. I also purchased a Apple (extended) Keyboard (usb cable connected with 10 key pad and full F keys).
When I initially plugged in the keyboard the OS setup screen indicated that it didn't recognize the keyboard. I tried setting it up several times, it doesn't seem to "see" the correct keys as I try to set it up. When prompted to "press the key to the right of the SHIFT key, when I do so I get a sound, no other response and the setup goes no further.) Some keys do not function properly (for example the sound up and sound down keys do not work). The general input for the keys work (I am typing this text with it), but it seems weird that an Apple device does not recognize another Apple device.
Is there something I need to do to complete setting up the keyboard? Are there any articles about this particular problem? I wasn't able to find any in the forum or help files.
Thank you,
Tim Kern

Thank you for the reply SilverSkyRat,
I checked the settings and USB ports for the keyboard connection. Still no-go with the "configure your keyboard" recognizing keys on the keyboard. I have also been trying to use the sound up and sound down keys and they do not function either. I will try another keyboard later today.
Thank you again for your reply.
Cheers,
Tim

Can you mirror a Mac Mini to an AppleTV 3 when the mac mini is not connected to a display?

Hello, I have an AppleTV 3 connected to my television and a late 2012 Mac Mini that is not connected to a display/monitor/tv, but I use it as my iTunes server to stream media to the appletv . However, I was hoping I could mirror the Mac Mini to the AppleTV in order to see Safari and regular Hulu on the television, but when I try, the picture is scrambled and crashes the mac mini. I turn on airplay mirroring using the Rowmote application on my iphone since I cannot see what the mac mini is displaying.
Additionally, I tried connecting the mac mini to a 2nd hdmi port in the television, while the appletv is connected to the 1st hdmi port, but the image was also scrambled with mirroring turned on. My television also has a VGA port that can connect to the Mac Mini, but I figure the same problem will occur and have not bought the DVI to VGA cords.
Is there a way to mirror a mac mini to an appletv without the mac mini connected to a separate display and if so, what am I doing wrong?
Thank you for the responses, I appreciate any help.

Welcome to the Apple Community.
AirPlay Mirroring requires a second-generation Apple TV or later, OS X 10.8 or better and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer).
On the basis of the specifications you have given for your set up, mirroring should work.

3 displays on Mac Mini (2009)

I know this has been discussed and there is stuff out there on this, but I need clarification.
I have a Mac Mini (2009) and currently have separate 24" dell monitors attached for the dual display. I want to add a third monitor, also 24" with same resolution (1900x1200).
what is the best way to do this to extend the desktop across the 3 monitors, rather than having a mirror on one? Will a DVI splitter only give me mirrored images on 2 of the 3 monitors? Is there a special adapter or cable I can use to get two out of one of the ports on the Mini and one on the other to come up with the 3 displays and extended desktop?
Thank you in advance for any help you can provide on this.

If you don't need high performance on the third monitor, then a usb adapter might be an economical way to go:
http://eshop.macsales.com/item/Newer%20Technology/VIDU2DVIA/
This would give you 3 displays and an extended desktop, AFAIK.
The specs (Supports up to 2048 x 1152) suggest you'd come up just shy of 1920x1200. I suggest contacting macsales (Other World Computing) as they have good tech support.
A splitter would only mirror the displays shared on the splitter.

Can not get Samsung 22" LED TV to work with Mac Mini (2009), 'No Signal' message. any suggestions?

I've just purchased a Samsung 5000series 22" LED TV to use with my Mac Mini (2009). I'm connecting using VGA with VGA adapter to MacMini. The TV is reading an error message saying there's no signal. Already tried with a 32" LG and it worked, as well as with a Dell moniter but can't seem to get this Samsung to work... PLEASE HELP!!

That is not totally true. Instead of using an analog VGA connection, try using a Mini DisplayPort to HDMI Adapter and HDMI cable with that Samsung Monitor.

Mac-mini 2009 airdrop not compatible in Lion??

Airdrop doesn´t work in Lion with Mac mini 2009 model.
Anyone thiks ther will be a firmware update or anything similar to fix this problem??

From the little bit of research I have done on this subject, AirDrop compatibility comes down to specific versions of the wifi chipset (Atheros / Broadcom) in the computer needing to support simultaneous networking via infrastructure mode (most common) and ad-hoc.
On those that do not support it, as it is a chipset hardware limitation, there will be no firmware update fix.
Without some type of a software fall back in AirDrop (think Bonjour sharing on the local network) a substantial number of recent systems are missing out on AirDrop.
I am still puzzled why Apple would use the compatible chipsets in some of their notebook systems as far back as 2008 and leave them out for another 2 generations on other systems like the mac mini and macbook air (mid-late 2010). It must have been some engineering and space limitation.
Copied from Apple here, for discussion clarity for other readers:
AirDrop supports the following Mac models:
    MacBook Pro (Late 2008 or newer)
    MacBook Air (Late 2010 or newer)
    MacBook (Late 2008 or newer)
    iMac (Early 2009 or newer)
    Mac mini (Mid 2010 or newer)
    Mac Pro (Early 2009 with AirPort Extreme card, or Mid 2010)
It does not look like my spring 2010 Mac mini is supported.

Mbp not recognizing external display

I have a 2010 MBP 2.8 and I'm trying to connect to a 24" Samsung LCD display to use as a 2nd monitor.   I'm using the mini display to DVI. And plugging a DVI to HDMI cord to that.
When I plug it into the tv and computer. The screen on computer flashes blue a couple times then nothing happens.   The computer is not recognizing the display.    I'm running Mountian Lion obviously and theres no option in "Displays" in preferences.
Am I doing something wrong? I had a old Powerbook G4 that I did this with all the time with Leopard OS.    Whats changed?

Hey all, did a software update on my partner's mbp yesterday (10.5.8, security update 2009-006) and had the same thing happen where our external viewsonic display was no longer being detected. Plugging the cable in and out of the mini display port had the same effect already mentioned here where the mbp screen flashed blue like it was about to recognise the external display, but then nothing. Selecting detect displays from display preferences also had no effect. Tried resetting the PRAM and also the PMU, still nothing. So I shut down the mbp; disconnected the mini display cable; then turned off the viewsonic monitor at the power outlet and left it off for 10-20 seconds. Then I turned the viewsonic's power outlet back on, started up the mbp, turned the monitor on and plugged the mini display port cable in and the external display was back and working properly. Have shut down/restarted numerous times since then and it's all still working normally. Not quite sure how/why this busted in the first place, or why turning the viewsonic off at the power outlet seems to have fixed it, but it might be worth a shot for those experiencing similar problems... and it sure beats having to install/reinstall a different os version (which was going to be my next option)!

Audio output from Mac mini 2009

I have a 2009 Mac mini with mini dvi and mini display port outputs. Just bought an hdmi tv to use as the display. I understand audio is not supported out of the mini DVI, but what about the mini display port? I was thinking of using a mini display port to hdmi cable. Trying to avoid an additional cable for audio.

There are two 2009 Mac mini models, Early 2009 and Late 2009. I can tell you for sure that the Early '09 Mac mini does not have integrated audio from the mini-DIsplayPort. It was my understanding that the Late '09 Mac minis built in 2009 also did not have integrated audio, but those made in early 2010 did. The only way to know for sure would be to test it. Apple reports that some m-DP adapters are not adhering to the VESA standard and even Macs with integrated audio in the m-DP do not with these poorly made adapters. Apple is only recommending the Moshi and Griffin adapters.

If your mini does not have integrated audio you can get a cool adapter that will solve that issue from Monoprice;

Mac Mini 2009 vs Leopard Server

Hi all...
I am hoping to get to the bottom of this asap, as I am looking forward to just getting on with things.
The issue is installation of Mac OS X Leopard Server 10.4 on a Mac Mini (Early 2009)
First of all.... Yes I have read the *Article HT3479* http://support.apple.com/kb/HT3479 and yes it allows you too boot your mini, however....
When you go through the installation process and are entering your information, there are several key steps missing from the interview[Server Assistant]. The main question missing is, "What type of installation" Standard, workgroup or advanced.
Another key set of questions missing is Network Setup.
So suffice to say the HT3479 does not address the issue i am experiencing.
Here are the methods I have attempted to use to install Server on this mini...
HT3479. {The result is that I can not run Server Preferences... Apparently the computer is in advanced mode and can not be reverted to standard}
The above method has been tried in the following examples...
* Install Mac OS X Client (10.5.6 from client disk)
+ Apply updates (at the time it was pre 10.5.7 so up to and including all updates to that time10.5.6)
+ Run Server installation from 10.5.4 Server Disk
+ Apply patches before rebooting
+ Run through shorted setup questions (See above)
+ check for updates before launching anything
* Install Mac OS X Client (10.5.6 from client disk)
+ Don't apply updates
+ Run Server installation from 10.5.4 Server Disk
+ Apply patches before rebooting
+ Run through shorted setup questions (See above)
+ check for updates before launching anything
I tried the above methods several times having no success
I contacted Apple support where I was asked to just try it again! and was told that nobody else was having these issues.
Great... 60Gb download capped reached so I had to wait for this month to continue.
10.5.7 update was released recently, so i thought I may be in luck.
So this month I have tried the above methods several times with the same outcomes.
In desperation I tried the following method...
Boot the Mac Mini in Target Disk Mode and running installation from an iMac targeting the disk in the mac mini. {The result is that during Boot up and Shut down verbose mode is invoked and there are numerous error messages in the log files, secondly I am experiencing several issues with DNS names etc.... won't accept SERVERNAME.local}
Anyway, this method gave me the most joy but still far from ideal.
Seemingly unfair it let me glimpse what leopard server can do, and yes i like what i see, but I really need to be able to install leopard server normally and have no issues.
*Hardware Configuration*.
Mac Mini (Early 2009) A1283 (2.0\1X1G\120\SD\AP\BT)
Upgraded RAM from 1GB to 4 GB (yes it works fine, full hardware test performed)
Upgraded HDD from 120GB to 320GB 7200 rpm (Caviar Black)
Samsung 22" monitor
Apple Keyboard (Aluminium with keypad) A1243
Apple Mightymouse A1152
Network
ADSL modem PPPOE
Apple Airport Extreme
Wired direct from rear of AEBS to Mac Mini
AEBS setup in DHCP, but reserved IP address for Mac Mini's Mac Address
Software
Mac OS X Server Version 10.5.4 [0Z691-6214-A] (Full retail version)
Mac OS X 10.5.6 Disk version 1.0 [2Z691-6344-A]
I am sure that others are experiencing the same issue, as many have listed similar issues to the above, however many are open ended with no resolution. I hope that if a solution is found or it is determined that there is an issue that news can be posted by apple so others are better informed before investing money in both products hoping to achieve a working network server.

I recently purchased a Mac Mini 320 GB model and OS X Server (Leopard). Before I purchased them I asked a couple of the Genius guys if I could run OS X Server normally on one of the new 320GB Minis? And the concensus among several Apple Store employees, was that yes, there should be no problem whatsoever...
So I bought the pair, and went through the install process numerous times, and was never able to get the standard installation until I resorted to dire measures which I have outlined below.
I tried to boot from OS X Server 10.5.4 on several machines at the Apple Store, and it does not boot any of the new machines (as of 2009.06.02). The normal install (use the os x server disk to boot) works perfect on an iMac 2.4GHz machine, and on a G4 Mirrored Drive machine, and on both of these machines the process is simple. Pop in the os x server disk, go get a sandwich, come back, answer a few questions, you are up and running, and life is great. It doesn't get any better...
The problem with the newer machines is that you must install the standard os x, get all the updates, insert os x server disk, and install os x server. The unfortunate part is that by the time you install OS X Server several items have already been set, OS X Server senses this and skips about 17 screens that allow for {"standard", "workgroup", "enterprise"} setup, and goes right into the "enterprise" mode.
One of the big conveniences with the standard setup is that quite a few things are created for you. Once you use the "standard" setup you can promote the installation to the "enterprise" mode by opening it with "Server Admin" which provides infinitely more control, but using "standard" setup to start with simplifies life considerably.
If you figure out how to do the "standard" install bear in mind that when it asks you for your administrative user account info it really wants :
name : Directory Admin
shortname : diradmin
password : astrongpassword
This will allow you to go from LOCAL to LDAPv3/127.0.0.1 when using Workgroup Manager
When it asks if you want add more users you can add one user, the "Local Admin" :
name : Local Admin
shortname : localadmin
password : astrongpassword (you will have to reset this password after you login as diradmin)
You can reset the "Local Admin" password via "System Preferences ---> Accounts"
and you can create the other users via the Workgroup Manager ---> LDAPv3/127.0.0.1 domain once you get DNS and Open Directory working.
if you use "standard" or "enterprise" the first thing to setup is DNS, everything else depends on DNS being configured correctly. "standard" really shines here because it won't let you screw up DNS.
You will need private DNS even if you have a provider handle public DNS for you.
If you are using standard you will be asked for, and can enter something like the following :
domain : crystal-palace.mac.private
machine : crystal-palace
if you are doing the "enterprise" mode you will also have to enter crystal-palace.mac.private in one more field,
Each machine will have a fixed PRIVATE IP address in the form of "192.168.1.n" and a "Computer Name" that was unique within the ZONE (the group of machines) via "System Preferences ---> Sharing".
Once you switch to the "enterprise" mode you can add more machines (using the "Computer Name" above) with their respective private ip addresses.
If you are using the "enterprise" mode, You want to setup Open Directory initially as "standalone", once that is working promote it to "Directory Master" via the "Settings" Tab. If you are using the "standard" mode, the Open Directory is setup automatically as "Directory Master" but there doesn't seem to be any way to add to the DNS, I think you have to use "Directory Utility" to do this. But if you've gotten this far it is easier to promote the setup mode to "enterprise" with "Server Admin".
I have a 1TB drive partitioned into 8 logical drives , the first seven standard partitions are named BUP_1 through BUP_7 and are provide 93 GB each. They are setup as test drives. The last partition is named TM_1 which is used for Time Machine backups and it provides close to 280 GB of backup storage.
On the first partition, I installed OS X 10.5.7 along with some basic applications that I normally use. I then created a dmg installer that I saved to TM_1 using disk utility and used that to install the image on the remaining six partitions (BUP_2 ... BUP_7).
The seven standard partitions then have OS X 10.5.7, which I basically use as test drives. It is here that I attempted different things trying to get this to be a simple deal. If one attempt didn't work I moved on to the next partition...
The BUP_n already have USERNAME setup as localadmin, not admin CHECK step ( 4 ) below. Also note that the dscl commands all have a dot following them.
Steps that worked for me, that allowed me to select the setup mode for os x server.
( 1 ) Boot mac into single user mode by holding down (CMD-S) during startup until you see text scrolling on the screen.
if the text on the screen stops, and you don't get the "root # " cursor, you may have to hit return once in order to get it. Once you get the root cursor you will need to enter the following commands very carefully. On the paths you can type part of the path and hit tab for auto completion. Everything is case sensitive...
NOTICE that USERNAME needs to be substituted with the correct shortname from step ( 4 ) in steps ( 6 ), ( 7 ) and ( 8 )
( 2 ) $ mount -uw /
( 3 ) $ /bin/launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist &
( 4 ) $ dscl . -list /Users
( 5 ) $ rm -R /Library/Preferences/
( 6 ) $ rm -R /Users/USERNAME/
( 7 ) $ dscl . -delete /Users/USERNAME
( 8 ) $ dscl . -delete /Groups/admin GroupMembership USERNAME
( 9 ) $ rm /var/db/.AppleSetupDone
( 10 ) $ rm -R /var/db/dslocal
( 11 ) $ mkdir -p /var/db/dslocal/nodes
( 12 ) $ cp -Rp /System/Library/DirectoryServices/DefaultLocalDB/Default /var/db/dslocal/nodes/
( 13 ) $ cp -Rp /System/Library/DirectoryServices/DefaultLocalDB/dsmappings /var/db/dslocal/
( 14 ) $ passwd
( 15 A) $ shutdown -h now (if you want to reboot outside of single user mode)
OR
( 15 B) $ exit (if you want to continue booting in single user mode)
I think that to make this an easy install, there should be a small script from Apple that you can run once OS X, and OS X Server are installed, and updated, that reset everything to pristine, so that after running the script everything that needs to be removed, or reset is done so that you can go through the normal 17 screens that allow for simple setup of OS X Server, just like if you had been able to boot from the OS X Server disk.
The answer I got from Apple Support is that when new machines come out it takes a while to get the correct drivers and release an installer disk for OS X Server. The unfortunate part is that there is no simple way to allow the installer to select which mode they need for the particular installation. They are forced to take the "enterprise" mode...
I am not SURE whether the steps I have outlined above cover everything, that is why I am suggesting that if would be far more accurate if Apple provided an installer script when they have NON_BOOTABLE versions of OS X Server Installer.
After three weeks and about 150 hours worth of work, I finally gave up and took the Mac Mini and OS X Server back and bought another iMac 24. Whenever a newer version OS X Server that is bootable on the newer machines comes out, I will get it another shot...
The guy I dealt with at the Apple Store kept saying, it works, you're just not installing it correctly. He also said "I've installed OS X Server on a Mini". But everytime I asked him, "Was it a new new Mini?" and he would respond, "Well, NO!". I also asked him "Were you able to boot the Mini from the the disk ?", he responded "YES!"
I ran into some other issues, for example one night I shutdown the server, and the next morning none of the passwords would work, not even the root password. So I came up with the following, hope this helps.
PROBLEM :
This morning for some reason the Mac Mini would not allow me to log in, neither as the Local Admin, nor as the System Admin. The database containing the login info must have become corrupted.
FIRST LEVEL REPAIR ATTEMPT
I started the machine using the Apple Install DVD, holding the "C" key to force the CD to boot
Once the installer screen came up, hit return and select :
( 1 ) Menu Utilities -> Disk Utility -> Select the Drive -> Repair Permissions
( 2 ) Menu Utilities -> Disk Utility -> Select the Drive -> Repair Disk
( 3 ) Quit out of Disk Utility...
( 4 ) Menu Utilities -> Reset Password
( a ) Reset the password for the root user
( b ) Reset the password for the local admin user.
( 5 ) Quit out of Reset Password...
( 2 ) Menu Utilities -> Startup Disk
( 6 ) Select the correct disk to use for re-start.
( 7 ) Re-Start
( 8 ) I tried this several times, but could never get the new passwords to work after re-booting.
There must have still been some corruption in the database.
SECOND LEVEL REPAIR ATTEMPT
( 10 ) reboot and to hold the CMD-S to boot into the single user mode.
At the root prompt, type in the following commands. I might have to hit return, if there is a white cursor that appears to be hung up waiting for input, just hit return, then you should see the root prompt.
First try :
( 11 ) root # fsck -f
( 12 ) root # mount -uw
( 13 ) root # passwd
( 14 ) root # exit
( 15 ) when the login dialog appears try to login as root
( 16 ) if you can login, go to :
( a ) System Preferences -> Accounts and reset the password for the Local User in question.
ELSE
( b ) Go to step ( 20 ) below
THIRD LEVEL REPAIR ATTEMPT
This is the command set to reset the local DB on the server
20. $ reboot and to hold the CMD-S to boot into the single user mode.
21. $ mount -uw /
22. $ mv /var/db/dslocal /var/db/dslocal.old
23. $ mkdir -p /var/db/dslocal/nodes
24. $ cp -Rp /System/Library/DirectoryServices/DefaultLocalDB/Default /var/db/dslocal/nodes/
25. $ cp -Rp /System/Library/DirectoryServices/DefaultLocalDB/dsmappings /var/db/dslocal/
26. $ passwd
FOURTH LEVEL REPAIR ATTEMPT
( 31 ) Shutdown the machine with the problem( we will call it the pm for problem machine)
( 32 ) attach a firewire cable to the pm on one end
( 33 ) attach the other end of the firewire cable to a good machine (call it gm)
In my case the gm uses firewire 400, and the pm uses firewire 800, so I had to get a cable that had firewire 400 on one end, and firewire 800 on the other,
( 34 ) start up the pm while holding down the "T" key until you see a large image floating around the pm screen. This put the pm into the "TARGET" mode, now it will behave like a drive, and you should see the drive on your gm desktop.
( 35 ) You can now copy anything you need from the pm to the gm.
( 36 ) Make sure you BACKUP anything and everything you want from the pm to the gm
( 37 ) IF YOU ARE WORKING ON A MACHINE CONTAINING OS X SERVER :
At this point, if nothing else has worked you will have to erase the drive and
( a ) re-install OS X, and
( b ) re-install OS X Server on the pm
( 38 ) IF YOU ARE WORKING ON A MACHINE CONTAINING OS X :
At this point, if nothing else has worked, from the Install DVD you can
( a ) Archive and re-install OS X on the pm
Another interesting thing that has happened several times now, is that I always install standard OS X on the first partition of the disk, and OS X Server on a different partition, and after installing OS X Server the machine would no longer boot from the standard OS X partition. This has happened like four different times, not sure what could be causing this problem. Booting from the install disk and running Disk Utilities to repair the disk (which comes back OK), and repair permissions always comes back with an internal error,and cannot be completed.
I have no clue what could be happening. I always had to reformat the drive and instal OS X all over again.
I have no clue what could be causing this to happen ?

How can I boot and run my Mac Mini on my 12" PwrBk display using firewire?

Welcome to Apple Discussions.
No reason why you should not be able to do it using Firewire Target Disk Mode. Here's what you do:
1. With both computers shut down connect both via firewire.
2. Startup the Mini and hold down "T" key immediately after chime.
3. Startup the PB and immediately after chime hold down Option key.
4. Select second HDD icon on the screen and click on the right pointing arrow.
5. Computer will boot from Mini's HDD.
Be sure to shut down PB completely before shutting down Mini.
Please do post back with an update or with further questions or comments.
