Mac mini and optical output problems

I have just purchased a new Apple Mac Mini connected it to my Tv via HDMI and now am having problems getting the sound working.
I have connected via optical output and the cable itself works and I can see red lights at either end.
When plugged into the Mac the 'optical output' is greyed out(it does change when plugged in)
When the volume control comes up it has a circle with a cross through it.I have tried what i consider most 'normal' things to try. Currently doing a update of the Mac software. Please Help, PLEASE!

So you have connected via a Mini-Jack -> Toslink cable from the Mac Mini to your receiver? You haven't specified what cables you are trying to use. My guess from the red circle with a X through your digital output is it may not like the cable you are trying to use.
I have the above described setup but I am able to select Digital Output in Sound Preferences. The volume control is greyed out for some reason but does not have a circle with the cross through it so I just control the volume via the receiver itself. iTunes still allows me control of volume, as do other video/audio controls in the web browser etc, it's just the main OS X volume control that is inaccessible.
Strange, but liveable.

Windows XP on Mac Mini and some graphics problems

I used BootCamp 1.4 to run a Windows Xp on my mac mini. Everything seemed fine, I installed the Bootcamp Window drivers. There is some problem, however, when I launch games. Screen Resolution is set on 1680x1050 pixels (Apple Display 20"), but when I open a game the screen is shrinked to a small box with resolution no more then 640x480 pixels. Graphics on games is OK, high details, fine rendering, but I can't understand why is the screen so small.
I've downloaded the latest Intel graphics video driver for 945 chipset, but still the problem resist.
Thanks to everybody in advance.

Hi Alex. When started a game, it should open at fullscreen, no matter what the resolution is. The problem with my games is that this box I am talking is the whole screen!
I tried to uninstall the video driver and rebooted. Without graphic drivers Windows loaded in the same small box (screen). Than I installed the drivers again and restarted. On the next start the video resolution was ok (1680x050) and it was fullscreen. I'm pointing out this because I think that problem is not only about the games, but it is something connected with the drivers, the hardware or the video card..
That's why I am asking for help.
Thank you.

Mac Mini and Bluetooth Recent Problems (Mighty Mouse, Wireless Keyboard)

Hello there,
I have an issue with my Mac Mini.
We had a storm here recently, so I switched my Mac off. After that, I turned it on, but to my surprise my Wireless Mighty Mouse and Wireless Keybord do not function any more. The green dot under the mouse nad keyboard flashes for a few seconds and turns off. I tried to plug my regular mouse and keyboard but it seems the do not work too. Any solutions?

i dont know if you have another mac around but have you tried repairing the disk by putting it into Target disk mode and hooking up another mac to it? if nothing else, try putting the install CD/DVD and boot from there by holding down "c" as it boots. if that works then it may just be a bad BT card. if it doesnt work then you may have bad usb ports. i hope you have applecare!
a tip for bluetooth HIDs, spread them apart. you will experience problems on occasion where their signals get crossed and they fail to sync right.
by the way, if you went the extra mile to turn off your mac because you were concerned about it, then why didnt you just unplug it from the outlet?

Mac Mini and MuVo V200 problem

I have Mac Mini .83 a few months now. Yesterday, I've, for the first time, tried to connect my MuVo V200 via USB. The problem is that Mac simply can't see MuVo at all!!! With other devices I have no problem. What I suppose to do?
Thanks anyone who can help?

Did you have the Mac before you bought the Muvo V 200? You should have read the box and listed requirements,if you bought this yourself. Below are the minumum requirements for the Muvo V 00 or 200.

Mac Mini and Gigabit Ethernet problems

My iMac will start to run on the gig network talking fine to my new Intel SS4000-E NAS, then after about an hour of inactivity the ethernet port will lose its DHCP address and drop to a 169 number.
If you open the network tool, you can not get a renewed address. The only way to get the interface back and running is to reboot.
I was working tuning Jumbo Frames to get the most out of the network, and I thought maybe it was the jumbo frames, so I moved it back to the default, but found that not to matter.
it seems to be the GIG port speeds that do this, if I run at 100Mb the port does not show this to happen.
Any comments Apple?
I have a Netgear GS116 switch, Intel NAS and several PC's, all with Gig cards, non of the PC's exibit this issue.
Anyone see this show up in their units?

We are not Apple, so we can't help you with that.
The machine isn't going to sleep is it?
Did you try a different port on the switch? Checking the cabling is an excellent idea. Sometimes they cheat and do not wire things to true Cat5 or 6 specs.

Are you using HDMI or an Apple Airplay Module to go to the TV Speakers?
If you are using an HDMI it's straight through output. The internal speakers are disabled.
If you are using an Airplay Module:
- Go on iTunes
- Locate the Airplay icon that has a TV with an up arrow icon much like your iPhone has for Bluetooth
- Click on that and Airplay to ModuleName

I have a mac mini and just purchased a moshi hdmi connector for my LED TV. The problem is, I wanted to be able to take my mouse from one screen to another, not just as a mirror image! Is it possible to do this some how?

Problem with Mac Mini and Panasonic PT-AE700 projector

I just bought a brand new Mac Mini and intended to connect it through hdmi to my Panasonic PT-AE700 projector (with a 10 m hdmi-hdmi cable and a dvi-hdmi adapter). However there is no signal recognized by the projector.
Any suggestions? I have tried with two different dvi-hdmi adapters between the Mini and the cable. Both work fine with my MacBook Pro, but with the Mini there is no signal.
Mac Mini Mac OS X (10.4.7)

Thanks again BSteely for your answer.
Unfortunately I still haven't been able to get anything out from the projector through HDMI.
However, I've found someone with a similar problem. It seems the problem is the lenght of the HDMI cable (which in fact is closer to 15 m than 10 m). HDMI is designed to handle at least those 10-15 m runs, but the problem seems to be DVI, which is only capable of something around 5 m. Since I'm converting from DVI to HDMI, I'm subject to DVI's limitations. And the MBP seems to have better capability of handling the weaked signal than the Mini.

Gefen should have an amplifier (HDMI Super Booster) that could solve the problem. I just ordered it to see if it could help in strenghtening the signal and solve the problem for me.

I just got a new Mac Mini, and now when I try to import photos into Lightroom, iPhoto try to load them first, then Lightroom can't find the files. Big problem. What to do?

I just got a new Mac Mini, and now when I try to import photos into Lightroom, iPhoto ties to load them first, then Lightroom can't find the files. Big problem. What to do?

Simple:
File -> Export to get your photos out of the iPhoto Library. In the Export dialogue you can set the kind to Original and you'll get back exactly what you put in.
Apps like iPhoto2Disk or PhotoShare will help you export to a Folder tree matching your Events.
Once exported, you can then trash the iPhoto Library - just drag it from the Pictures Folder to the trash and empty it.
After that, if you're entirely neurotic about it, just put the iPhoto app in the trash and empty it.

Airport Express problems with new MAC MINI and DLINK router SOLVED

Hi just thought I would post this as it may well help others experiencing similar frustrations with new core duo mac mini and wireless connection or quality problems across the network / internet etc
I have a 3 week old, new mac mini core duo 1.8ghz 2gig ram, 120gb disk - First Mac, connecting to my exisiting wireless network via DLINK ADSL Router 2MB Broadband also one windows laptop and pc also wireless on the network and two airport express potins to stream itunes to
Problem was briefly
Mac worked fine, but the network connection just far too slow, laptop and pc, 1800+ kbps downstream mac mini 90 - 150kbps (http://www.adslguide.org/tools/speedtest.asp)
also if i ping the router directly from terminal (ping -c 20 192.168.1.1) average response 12+ ms with 20% packet loss, yet laptop and pc avg 2ms no losses
Spent 2 evenings on frustrating calls of more than 1 hour each (due to being cut off , then ring back and closed etc etc) and carrying out a the helpdesk troubleshooting (I am an IT consultant I think I am above this level), eventually an archive and install of the os as well
last night I call for the third time, insisting I dont wish to carry out any further troubleshooting, and want it replaced and resolved or my money back
I receive a call back from product specialist (not sure if thats mac mini specialist or airport) but we resolved the issue (his knowledge far superior to the help desk do this do this attitude)
between us we carried out the folowing and resolved the problem and I am now very happy
mac now downstreaming also in excess of 1800kbps (as expected for 2mb broadband)and no packet loss
This problem was resolved by switching off the turbo option hidden away in the routers settings, under wireless configuration
Supposed to improve performance, but its rubbish and will make hardly any difference under mac os to the speed but will certainly affect your mac mini performance(you may have a similar setting switched on in your routers and mac os dont like it)
We stumbled across this by first disconnecting one of the airport express devices from my dlink network, and using it on its own default apple wireless settings, effectively making it a standalone wireless network, and not via the dlink router
we then carried out the same ping with the ip address of this device (from airport admin utility default 10.0.1.1) and the results were fantastic 2ms avg no package loss
this established it was something with the router, and how we then interrogated the routers settings and found the turbo on option within wireless configuration
you may not be able to replicate this if you dont have an additional network you could join (such as airport express), but probably worth checking your own router settings for something similar
Hope that may be of assistance to others, sorry that its a bit long winded and garbled, but I'm just so excited to finally get my new mac working as i would expect it to
Also perhaps insist on speaking to a product specialist immediately that the helpdesk are unable to help you

Hello macfar14. Welcome to the Apple Discussions!
For just streaming iTunes and/or for sharing a USB printer, the AirPort Express Base Station (AX) just needs to be configured as a wireless client ... which you already attempted to do.
Just to be sure nothing was missed, here are the basic steps to do this:
Either connect to the AX's wireless network or connect directly, using an Ethernet cable, to the Ethernet port of the AX, and then using the AirPort Utility in "Manual Setup" mode, make the following changes:
AirPort > Wireless
o Wireless Mode: Join a wireless network
o Network Name: <existing wireless network's Network Name or SSID>
o Wireless Security: <select the encryption type of the existing wireless network>
o Wireless Password: <enter the existing wireless network password>
o Verify Password: <re-enter the existing wireless network password>
Music
o Enable AirTunes (checked)
o iTunes Speaker Name: <enter desired speaker name>
o iTunes Speaker Password: (optional)
o Verify Password: (optional)
o Click Update to write the new settings to the AX
In iTunes:
iTunes > Preferences... > Advanced > General
o Look for remote speakers connected with AirTunes (checked)

Hello, I just bought a 2013 Mac mini and I cannot get the sound to output to my Dell U2713HM monitor. I went to sound output but even though my Dell shows up there when I select it there is no sound output to it. I am using a mini DP to DP cable...

Hi Alxx911, and John Hammer1. After reading John's reply - " You can plug something into it's headphone jack. though" . I thought i'd try out of curiosity. I plugged in some headphones. I didn't expect anything to happen and nothing happened. The audio jack is for the Dell soundbar which is optional.
Here's a direct copy and paste from the users manual: Section About Your Monitor.
Attaching the Soundbar AX510 / AX510PA (Optional) CAUTION: Do not use with any device other than the Dell Soundbar. NOTE: The Soundbar power connector (+12 V DC output) is for the optional Dell Soundbar AX510/AX510PAonly. To attach the Soundbar: 1. Working from the back of the monitor, attach the Soundbar by aligning the two slots with the two tabs along the bottom of the monitor. 2. Slide the Soundbar to the left until it snaps into place. 3. Connectthe Soundbar with the DC power connector. 4. Insert the mini stereo plug from the back of the Soundbar into the computerís audio output jack. For HDMI/DP, you can insert the mini stereo plug into the monitorís audio output port. If there is no sound, check your PC if the Audio output is configured to HDMI/DP output.
This monitor has no speakers. (Like John Hammer1 mentioned). The no speakers feature was one of the reasons I chose this monitor.
Good Luck !

I have the Numbers-applications on both Mac mini and Macbook Air. My problem is that they don't sync so when I create a Numbers-file on the MacBook while travelling, it will not be on my Mac mini when I get home :(((

Hey iWeb plubishing problems,
I would first check to make sure that you meet the system requirements for OS X to support Documents in the Cloud. For that your Mac’s needs to be running at least OS X Lion 10.7.5 or later to make sure that everything syncs. Take a look at the article below for more information.

Problem with Mac mini and HP w2207h

I have a new Mac mini and a HP w2207h screen. I have a problem with the resolution. The screen wants to be on 1680x1050, but when i turn that mode on, the screen is just blinking and you can't see anything. so i have to use the 1080p modus. But it's kind of blury. Can anyone help? Does apple has some kind of support mail??

Don't waste your time or money on the adaptors. I have a hp 2207h and I tried th dvi to hdmi and the dvi to vga, neither work, I still don't have a working monitor. Waited on the phone for tech support for 30 minutes. Then got a total line of crap.
This monitor works flawlessly with my comcast motorola hd cable box, with my sony dvd player, with my toshiba laptop, with my hp computer. But will not work with a mac mini... The only logical reason given the wide varity of equipment it will work on, is that apple does not support HDMI standards, if they did, it would work.
The apple does work on my 40 in tv. But thats not where I want it. So, this is useless to me. And after the line of crap I got from tech support, I'm thinking about quiting apple all together.
This ***, I was really excited about my first apple computer. Now after 4 hours, and nothing but frustration and no support at all from apple, I'm thinking about giving up and sticking with PC's from here on out. Worst experiance ever.
I may even switch to android and chuck my 4...

New 2012 Mac mini having screen resolution problem when I connect to either 27" LG or 22" Hannspree monitor. Tried mini display port to VGA/HDMI and HDMI to DVI-D cables... all same isse

New 2012 Mac mini having issues in connecting to third party Monitors. Connected my mac mini to a 27" LG monitor. Text looks blurred. Tried connecting to the monitor using 3 options. 1) mini port to HDMI, then HDMI cable to LG monitor. 2) Mini port to VGA, then VGA cable to monitor 3) HDMI port on mini mac to DVI-D cable then DVI to DVI cable... In all cases text is not clear. Anyone has similar issues with latest mini mac. The monitor works fine when I connect to a windows 7 Samsung laptop. Any input is highly appreciated. Thanks in Advance

Why do you use always 2 cables? There's a lot that can go wrong.
1.) Hardware:
- Use only one cable, best an HDMI->HDMI cable. It doesn't need to be an expensive one, they've proven to be no worse than those "esoteric", expensive ones.
- Set the monitor to the HDMI input.
- The modes you are listing are only "picture modes" changing color/brightness/contrast settings, not resolution or the likes, so pick the one you like best later, or enter your own settings under Custom.
2.) OS X:
- Usually the Mac detects the screen itself and chooses the best settings, so by default you need to do nothing than make a proper hardware connection to get a decent image.
- However, there have been issues with new Mac Minis and particularly their HDMI ports. But reportedly they have been fixed with a software update. So, launch the App Store and check under Updates if there is one for you to install. If so, do it; otherwise you should be good to go.
- If you require, go to System Preferences -> Displays. In the Dispaly tab, by default, "Best for display" should be selected, and that is typically true. If you want, select "Scaled" and 1920x1080, plus a frequency from the list (where higher is usually better, but just pick the one that works best for you). If you can't see a change to the better, you best go back to "Best for display".
- If you are not happy with the colors on your screen, you'll find eventually more than one choice in the Color tab, though your particular screen should be in the list and its Display Profile should get you the best result. (Double-check picture modes on your display: if you're far off there, you won't make it much better with the Mac's settings).

Mac Mini and thunderbolt/vga to LCD TV

Hi All,
Here is an interesting one......
I have just taken delivery of 5 new Mac Minis which have the thunderbolt port on them. The Mac Minis each connect using displayport tb/vga adapter to a switch then on to 5 LCD TVs.
The HDMI/DVI is not used.
In this config, if I start a Mac Mini the display will not route through the Thunderbolt/vga adapter to any of the TVs (even though I have selected them on the switch). The display seems to want to go through the default HDMI port.
If I connect a standard PC monitor to the tb/vga adapter and reboot, the screen shows correctly on the monitor. If I then change cables without a reboot, the LCD TVs show correctly!
I can add the PC monitor as a second monitor using HDMI/DVI and ensure that the outputs are mirrored AND that the VGA display is the primary. However, on reboot it's as if the details are all forgotten!
Searching around it seems that there are issues with Mac Minis and VGA connections to LCD TVs. That said, I wanted to put my environment out there and see if anyone had an ideas.
Interestingly enough, with older Mac Minis (without the tb/vga) it works perfectly well, indicating a problem with the new Mac Minis.
Thanks for ANY ideas!!!!

Hey Spost!
You have explained exactly what happened to me last night. I was afraid it was part of the 10.8.3 update or the latest ATV software update that hit this week. I tried from my macbook pro and the airplay from 10.8.3 and the atv software worked fine.
Previously my mac mini was connected to a monitor in my basement but last night i made it "headless" and moved it to my "server closet" airplaying prior to the move worked great ... then last night 4:3 Green Screen.
My guess is the computer needs to be connected to a external display in order for airplay resolution to figure itself out. Via Logmein i could see that the Mirror mode wanted to use the resolution that fit the mac and not what was best for the Apple TV ... Even forcing the change made the setting go right back to this mac.
Looks to be a bug in a plist file that apple would need to fix as many people run headless mac mini's and now wish to AirPlay to their Apple TV's without the need for a external cable run.
