My mac mini (2013) dose not show me wifi connection.

my wifi sign on my mac mini 2013 OS X 10.8.5 (12F37).
it started before my last update and hasnt been resolved after getting OS X 10.8.5
it shows on the WIFI sign WI FI: NO HARDWARE INSTALLED.
can you help me?

Test after taking each of the following steps that you haven't already taken. Back up all data before making any changes.
1. If you can connect to the Internet via Ethernet, Bluetooth, or a USB network device, make sure all available OS X updates are installed. If Wi-Fi is your only means of network access, skip this step.
2. Reset the NVRAM.
3. Reset the System Management Controller.
4. Boot into Recovery. In the menu bar of the OS X Utilities screen, there's a Wi-Fi menu. If it works, select Install OS X. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
5. Take the machine to an authorized service center for testing.

I have mid 2009 Mac Book Pro running 10.9.1. The hdmi mini port no longer supports sound on the Sony TV. This is apparently a change. It no longer shows as an option in system preferences/sound.Any ideas?

The 2009's didn't support sound on HDMI. That came in 2010. Are you sure it ever worked?

No sound on HDMI with Windows 7 om Mac Mini 2010

Hi,
i've installed bootcamp (windows 7 64 bit) on a new mac mini. When I turn on power an boot windows there's no sound over HDMI. The windows device manager says that everything is working properly.
Then I boot mac os and HDMI sound works fine in mac os. Then booting windows again HDMI sound is working in windows too. But when I turn of the mac and turn it on again booting windows sound is missing again.
Any suggestions? I updated to the latest nvidia hdmi audio driver without success.

Found a workaround: The problem is not the NVidia HDMI audio driver but the Microsoft HD audio driver / device. If you have no sound over HDMI with your Mac Mini you have to
1) Find out the hardware ID of the Microsoft HD Audio Device:
* windows device manager -> system devices -> High definition audio controller
* right mouseclick -> device properties -> Details -> select HardwareID
2) Use the devcon command line utility to disable and enable the device:
devcon disable "HardwareID"
devcon enable "HardwareID"
And you will have HDMI sound again.

No Sound through HDMI - Mac Mini

Hello Forum, New user to this forum, I have a problem, I have bought Mac Mini ( August,2010) for home use and recently bought LG -32LD450 - 32". I have connected my TV directly to Mac Mini using a 1.3X HDMI cable. I have video/ display - however no sound. All i can hear is sound from the Mac Mini's internal speaker. I tried to change the setting through - System preference/sound/output. It displays - LG / HDMI - however i cannot select, the setting is active with internal speakers only. Please advise how i can obtain audio from the TV.
I forgot to mention the message seen in System Preference/Sound/Output - LG TV HDMI - Settings for the Selected Device : The Selected Device has no output controls.
In addition to the above, i have tried to check the output controls through Utilities/Audio Midi Setup. Here too i am not in a position to alter HDMI Settings.
Help in this regards is highly appreciated...thanks
Please help

Krusdublin: I am experiencing similar issues with no real solution yet:
I have a Mac Mini 2010 connected to a Sony Bravia HD TV via an HDMI cable
sound output via TV speakers was not working when I first connected the two (about 4 mos ago)
couldn't figure it out- and just used an headphone cable to connect the mac mini to a stereo
somewhere between then and a month ago I disconnected all incl. power, and reconnected as I had to re-setup my tv (all reconnected in the same outlets via HDMI) (also got rid of the stereo at this point)
then about a month ago I was back in the Sound preferences and found that I was able to get audio output via the TV speakers.
about a week or so ago I disconnected all incl. power, and reconnected as I had to re-setup my tv (all reconnected in the same outlets via HDMI)
however, about 3 days ago, sound output via TV was no longer an option
when I say it is not an option, I have two lines under name and types as follows:
"Internal Speakers" > "Built-In Output"
"SONY TV" > "HDMI"
when I switch from internal speakers to HDMI, I notice that the sound volume bar at the bottom of the screen goes faint, and I can't adjust the volume using the sound keys on my keyboard (bluetooth)
the speaker icon in the top right of the screen is also greyed-out and not changeable...
I notice that when I switch input on my TV aerial to the MacMini (HDMI 1) I get a little yellow triangle with exclamation mark in it, and the text: "AUDIO only" at the bottom right of the tv screen. (In not sure if I had this before or not - dont completely remember seeing it, but vaguely do...)
I've also updated my macmini whenever an update is released (within a few days)...
I've spoken with an Apple tech over the phone and went through a number of reboot (while holding down certain keys, etc.) to no avail. She then recommended that I go into the Apple store and have the mini checked out....
At the apple store, the apple tech took the machine to the back, out of sight, and returned about 20 mins later to say that it was working fine. I asked to have it hooked up to one on display - so I could see for myself. We hooked it up to an HDTV via HDMI and booted up. Went to System Preferences > Sound and selected: "Panasonic TV" as the output device. I still could not adjust the volume bar (it went greyed out) - but I could crank up the tv volume directly and get sound. Great! Sort of... While now I could get sound - it was not the same as before where I could control the sound through the mac - only directly through the TV. The Apple guy said that he didn't know what I was talking about - and said that they way the machine was now working was the proper way. He unhooked my mac mini, and gave it to me, and walked away.
Frustrated, I walked down to the Sony Store to try out the mac mini there. Same result as in the Apple store. I could control sound directly via the TV, but not through the mac mini controls.
Took the mac mini home, reconnected everything and now get sound through the TV - but I cant control it with the mac mini on-screen controls, nor the volume buttons on the mac blue tooth keyboard.
Today, I was watching a movie via itunes, hit pause, and went to do something for a few minutes. When I returned, the TV indicated 'no signal' via the HDMI (I assume because the mini went to sleep.) Tried to wake the mini - but couldn't. Had to resort to pressing the button at the back. When the mini came back, I had no sound at all coming through the TV speakers, even though the sound preferences settings were still the same. I had to resort to shutting down the mac mini, and then unplugging the power on the mini for a few minutes. Powering back up, sound was again able to comefromt eh mac through the TV speakers - but still could not control sound using the mac mini controls.......
Thats where Im at so far....
Aarrgh.
THOUGHTS?
Thanks in advance,
MAJM

Mac mini no surround sound via HDMI to TV

I have a MacMINI 2011 which is connected via HDMI cable directly to my Samsung UA55HU8590 TV.
The problem is that the MAC is not delivering a surround sound. If I e.g. watch a movie via iTunes I can only listen in stereo not in DTS or any other dolby sound.
I see in the midi audio setup at the HDMI entry that all my 5.1 settings are greyed out.
I have the latest Yosemite installed.
How can I transfer surround sound via HDMI to my TV?

Try:
Force 5.1 out over HDMI

I want to use a video projector with powerpoint can I use my mac to drive it- and what about sound?

Hi Scott,
You should be able to. If the projector has a speaker with acceptable sound, that's one option, otherwise powered speakers or a surround system.
What connections does the projector have?
Exactly which MBP do you have?

I have my mac air hooked to the tv using thunderbolt and HDMI

I have my mac air hooked to the tv using thunderbolt and HDMI the background screen and screen saver are the only things that will appear, but no icon's and cursor what I'm i missing?

That's called the "extended desktop mode". Your screen is logically extended to the right (by default). Drag an application off the right side of your MBair screen and it'll appear on the TV.
You can also toggle between extended desktop and mirror mode by pressing CMD F1.
Visit all the settings in System Preferences > Displays > Arrangement tab.

My bootcamped Mac Pro version 10.6.8 has sound in the windows 7 side but no sound in the Mac side. Any suggestions?

Hi there, @James.
You should check the audio output from the settings.
1) Open the System Preferences.
2) Click the "Sound" icon.
3) Follow the steps.
I had this problem and that's how I solved it.

My latest problem is that the Apple site will not recognize my equipment by it's serial number. I know the mini is old, but I like what it did for me and don't necessarily want to "upgrade".

This is the iPad in the Enterprise forum. You'll be more likely to get help with your issue if you ask in the appropriate iPod forum.

Mac Mini 2013 stuck on apple logo

My Mac Mini is stuck on the apple logo with the spinner underneath it. I was running a program and put the computer to sleep. When I started it back up, the program was stuck. I couldn't get to the command options and shut it down. When it started back up, I typed in my password, but it continuously got stuck on all my account logins. I tried to safe boot it, but it just loads the progress bar and goes back to the logo and spinner, even if I leave it alone for half an hour. I tried to use the option button, but none of the options work. I tried unplugging everything but the monitor and turned off my Apple Bluetooth mouse. Still didn't work. It is a 2013 model, so it has no CD drive. PLEASE HELP! I need this working soon. If it is possible to migrate another Mac to fix it or migrate one onto the disk after I erase it, please let me know. If not, give me some advise. I need help ASAP. Thanks for your help!

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
     a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

USB3 Speeds mac mini 2013 and Hitachi Tuoro 4TB

I am new to USB3 and have always used FW800 before , I just got a new Mac Mini and an Hitachi Tuoro 4TB I am finding the read/Write Speed with Backmagic Disk Speed Test are really slow.! my old FW800 drive is faster .
anyone have any idea on this?
Write 64 Read 64 Hitachi Tuoro 4TB
Write 81 Read 83 Iomega 1TB FW800 (bus powered)

FireWire is more efficient than USB so even though USB3 is theoretically much faster than FireWire 800 a lot of that advantage is lost. However I would not have expected the results you see.
I would also normally have expected a 4TB drive to be faster than a 1TB drive being that a 4TB is likely to use newer faster technology.
You could check the formatting of the 4TB drive, for use on a Mac it should be partitioned using GUID and formatted using HFS+ Journalled. If it is MBR and FAT32 this will not help.
Also, if you have USB2 devices plugged in as well and this could include the mouse and keyboard they maybe slowing down the USB3 device. If you connect them to different sockets on the Mac mini then this should prevent this.
