Can't get MAC MINI HDMI to consistently display on TV monitor
My new MAC mini is connected to a new HD Samsung TV. Initially had problem showing HD movies because I had Mini connected via VGA. Purchased appropriate connection for HDMI and HD movies show great, for a while. Appears that sometimes zhen the mini sleeps, monitor doesn't see mini with HDMI connection. When I switch back to VGA, the monitor once again sees the mini. Recently HDMI was working great until I downloaded updated software, and now once again monitor doesn't see HDMI, only sees moni when I reconnect via VGA. I've checked all connections many times and can't find the issue. Looking for any assistance.
THANKS
Update: Got the HDMI working again. Since I couldn't see mini mac with HDMI, hooked up VGA and restarted. While mac mini was restarting, changed connection to HDMI and low and behold, the monitor saw the mini in HDMI. Don't know if that's the optimum way.... but it worked.

How can I get Mac Mini to accept bootable installers for Mountain Lion ? They work fine on MB-Pro
I've had a Mac Mini (late 2012) for the past week and need to do a complete reinstall to get rid of very mucked up Server.app settings that I can't get rid of even though I uninstalled Server.app and what I thought were all of its Library files. I need to get the Mac Mini back to pristine, factory default to start over. Then I'll be able to put Server.app into a VM so I can trash it if need be without mucking up the rest of my system.
I have both a bootable recovery partition on an external hard drive (My Book firewire) and a USB bootable installer with a fresh edition of Mountain Lion. I know the USB installer works just fine because I used it to do a clean install of my MacBook-Pro just last night. Went like a charm.
When I start up the Mac Mini with the option key held down, everything seems fine -- I see both the USB drive and the My Book's 2 volumes (1 for data, 1 for the Recovery partition). But when I select either the USB drive or the My Book Recovery partition as the start-up drive, I get a screen with a circle with a line across (the no-entry traffic sign), with no way to go back or forward. So the computer has to be rebooted.
Any suggestions as to how to get the Mac Mini to recognize bootable installers that MacBooks are able to see?Late 2012 Mac mini uses a special Mountain Lion version that it's only compatible with this Mac and you can only get on Internet Recovery because it's not available in the App Store. If you want to reinstall Mountain Lion, press Command, Option and R keys while your computer is starting

Mac Mini 2009 won't display on Acer Monitor P166HQL
I'm currently living in Brazil and due to continuing problems with my 2006 MBP running 10.6.8, I've just bought a 2009 Mac Mini which apparently is running Mavericks. The display works fine with the MBP using a DVI-Serial connector [the monitor only has serial]. When i connect the monitor to the Mac Mini I need to add a mini DVI to DVI connector into the equation. so the chain is...

Mac Mini HDMI Output Problem w/ LG L246WP
NOTE: This appears to be unrelated to the "screen flickering" that has been noted previously.
I'm using a fresh new Mac Mini 2012 with an LG L246WP LCD monitor. The monitor has HDMI, VGA and Component video inputs.
When I attach the monitor to the Mini DisplayPort output, using a Mini DisplayPort to DVI adapter connected to a DVI to HDMI cable, the display functions properly at all resolutions - including the native 1920 x 1200 resolution that I use it at normally. All resolutions are clearly displayed in the "Displays" System Preferences pane. The display looks perfect, functions properly.
When I attach the monitor to the HDMI port using an HDMI cable, the display does not fucntion properly. The display is shifted about 80-100 pixels to the left and about 20 pixels up, creating black bars on the bottom and right sides. Because of this, a large portion of the display is not visible including the menu bar and most of the left side. Additionally, the settings are reduced to "Best for Display" or "Scaled", with resolution options under "Scaled".
This is not acceptable. I had planned on simply using the Mini DisplayPort output as a workaround, since I already have the DVI adapter from an old setup, but I need to use Thunderbolt to access external hard drives for rapid data transfer. One of my Thunderbolt accessories does not have two ports, so I can't simply add the Mini DisplayPort adapter to a chain. The HDMI port needs to function properly with my monitor.
It's important to note that this monitor has functioned properly with many other comptuers running OS X, Windows and various Linux flavors and it hasn't ever done this before. I've tried several different HDMI cables, ruling that out as a problem. I've tried the HDMI to DVI adapter that ships with the Mac Mini 2012 along with two different DVI to HDMI adapters, ruling that out as a problem. I tried attaching several HDMI devices (game consoles, DVD players, etc) and they all function properly, ruling out an HDMI issue as a problem. The monitor functions properly when attached through the Mini DisplayPort to DVI adapter, so it's not a problem with the monitor. I've reset the PRAM already and the installation of OS X 10.8.1 is stock with no modifications or migrated data. I've tried the suggestions on the HDMI FAQ (although there's no "underscan" option available in Displays)
I tried to call AppleCare and after describing the problem I got disconnected with no callback. I started another ticket, described the problem, discussed the previous disconnection, was assured that I'd be called back if disconnected, and haven't heard back in two hours. So I started to dig into the problem in earnest.
This gets pretty technical.
After substantial research, it appears that this issue is related to the EDID that the monitor sends to the computer and, crucially, the way that the driver responds to it. For some reason, the HDMI port is recognizing the monitor as a CEA device instead of a monitor. As a result, it's restricting the monitor's available resolution to the native resolution that the CEA 681 Series Extension describes ("Best for Display") and all other resolutions (including 1920 x 1200) are only available as "scaled". For some reason that I can't discern, all resolutions (even the 1080i and 1080p options) have similar deformities.
I've attempted to fix this by placing an appropriate override file in /System/Library/Displays/Overrides with an edied EDID removing the CEA-enable flag from byte 127 but, even after a reboot, the OS still insists that it's a CEA device and it won't allow me to force it to recognize the monitor as a 1920 x 1200 LCD Monitor.
How did I come to this conclusion and develop the fix? A nearly identical problem description showed up on the following website, with details on how this user fixed the issue:
http://byuu.org/articles/computing/edid
They used a convoluted process that involved dismantling the monitor and flashing the EDID on the monitor itself. It fixed their problem. I'd prefer not to go through that process just because one computer has a problem with it. Frankly, I'd prefer if the new Mac Mini performed properly in the first place.
TL;DR: The Mac Mini 2012 doesn't work right with the LG L246WP through the HDMI output. Everything else works fine with it. This is very uncool. It's most likely to be an issue with the driver for the Intel HD Graphics 4000 GPU that are bundled with OS X 10.8.1. The Mac Mini 2012 won't update to 10.8.2 (yet), so I can't test it.
Anyone have any other ideas? Anyone else using a Mac Mini 2012 (or 2011) with an LG L246WP monitor? Anything simple I've missed?Problem Resolved. But it was complicated. And a huge pain in the rear.
TL;DR: I flashed the EDID as described here. This is not recommended for the weary. Ideally, Apple should release an update OS X that will include the updated Intel HD Graphics 4000 drivers that utilize the CEA flag properly.
Here's the detailed version. As mentioned above, this isn't recommended for the weary. An improper (or interrupted) EDID flash can have seriously unpredictable effects on a monitor's performance.
Step 1: Get a Windows PC set up with a floppy drive and find a floppy disk. Use this system to format the floppy as a MS-DOS Boot Disk and copy over the "ddcw" program described at the aformentioned link.
This took awhile, but I was able to cobble together a temporary frankensystem with parts I had laying around. In installed XP and formatted the disk with XP's format tool.
Step 2: Grab EDID data from the monitor, modify it to disable CEA mode at bit 127 and make sure bit 128, the checksum, is appropriate.
This also took awhile. Several graphics cards I tried could not read or write EDID data. I ended up swapping AGP cards in my frankenstein box until I found one that worked - a generic GeForce4 4200.
Once the EDID data was written to the floppy, I edited the text file containing the EDID data to change the last two hex octets from "01 33" to "00 34" (00, to disable bit 127, and 34 is 33 + 1, which satisfies the checksum) and formatted the text file to match the sample included in the EDID_Write.zip file. Your mileage may vary - make sure the checks.
Step 3: Write EDID data to the monitor.
The link above mentioned three options: Easy (monitor's EDID is unprotected - write away!), Hard (monitor's EDID is protected - use service mode to attempt a fix), and Very Hard (monitor's EDID is protected, hardware modification is required).
Luckily my LG246WP simply needed to be put into service mode as described at the link above (menu + power) and once started up in service mode, I simply enabled "Aging Mode" (whatever that means) and attempted a DDCW write of the updated data.
Step 4: Profit!
After doing this, I powered off the monitor and powered it back on with the Mac Mini attached. The display functions PERFECTLY with HDMI out, just as it does using the Mini DisplayPort to DVI adapter. -
2011 Mac Mini HDMI only 2Ch Stereo
Wow is this frustrating. I've had my Mac Mini for about a week, and for the life of me, cannot get surround sound working via HDMI. I've read so many posts about people with this problem but I can't find a definitive answer for a fix. All I want is for the Mac Mini to passthrough the audio so that my Pioneer Receiver can handle all of the Dolby stuff.
Setup is simple -
Mac Mini ------> HDMI -------> Pioneer VSX-1020 Receiver --------> Samsung 55" LED
Inside of the Midi Audio options, it shows my receiver as the audio device, and I have all of the options for 2ch, 8ch, etc. I also selected Dolby 5.1. I can only get PCM or Stereo to display on my receiver while ticking through these channel options, while I would expect Dolby to display if it is receiving a Dolby signal. Also, when I do the test tones in the Configure Speakers area, I get the correct test tones from all channels. BUT.........
No matter what I play whether it be iTunes, VLC, etc, I am only getting 2 channel sound and my subwoofer.
Can anybody help?? This seems like such a simple task yet it has me pulling my hair out.ive had my 1021 for about 2 months and i think its great. Do you like yours?
i have 5.1 using optical cable to one of the optical in ports on the 1021. But you will need an optical-to-miniOptical adapter tip to use in the mini.
then make sure that any app through which you want 5.1 has that specified in its prefs. (like VLC)
VLC always has the option ' out through system', and if the system is optical out, then 5.1 will pass. -
Hello,
I have a CD stuck in my new Mac Mini HDMI.
* It does not appear in the Finder as a CD.
* Disk Utility shows the CD drive itself, but all options for eject, format, etc are all greyed out.
* Booting with the mouse button down does not work (I have a bluetooth keyboard; however, I selected to stop using it and connected a wired keyboard)
* Booting with C down does not work
* Booting with Option down until getting to the firmware boot disk selection menu, then pressing / holding the eject button does not work
* I used the Terminal command "drutil eject", the drive makes the eject noise, but nothing comes out
* Tried System/Library/CoreServices/Menu Extras/ double clicking Eject.menu - the menu only has a greyed out drive listed
I think that's everything I've tried. Please let me know if there's anything else I can try.
Thanks for all your help!I figured out the 'problem'
Let me pre-face it by saying, my wife originally emailed me at work talking about this disc she couldn't get out.
Flash forward to now. I was fishing around with my work badge (thin hard plastic) and I couldn't feel anything that felt like the edge of a disc. So, after getting up the nerve I took a blank DVD, and slowly let the drive catch it and pull it in. Loaded up just fine.
I guess the "Stuck CD" must have evaporated
Good new is, I now know every single way to get the disc out should this happen to me for real (short of completely disassembling the Mac Mini). For now, all I can do is laugh (quietly so my wife doesn't hear).
Thanks for helping out Boece! -
Hello. I have a mac-mini (mid 2010) and with bootcamp, was successfully running XP.
I then decided to upgraded to Windows 7 had lots of trouble installing it on my existing bootcamp partition.
I finally was able to install Windows 7, by just booting off the CD and letting it install that way.
But reading more on it, I think I was supposed to use Bootcamp to do it for me...
I had thought the Bootcamp Assistant was for only fresh installs of a Windows O.S. where no partitiion existed previously.
I had a partition so thought Bootcamp wasn't required for my needs.
But now, inside Windows 7, I have 0 drivers installed. I have an AirPort Express, so on the Mac side, I downloaded
and installed the Windows version of AirPort Utility and copied it to my USB stick. Then
I exported my settings to a text file on a USB Stick, then on Windows was able to successfully install AirPort Utility and import the settings.
But it still doesn't find my network. I am pretty sure I'm broadcasting my SSID...
So I need to know the following:
1) How to know I'm broadcasting my SSID - where do I find this in settings?
2) How I can install my mac-mini drivers on Windows 7 so I can use my existing wireless network, now that I've gone through the installation without using Bootcamp?
3) Do I need to set up network adapters and all that stuff in Windows 7 first? If so, how and what drivers do I need?
One other thing I tried was downloading Bootccamp 4.x and installing that on Windows 7 to see if it gives me the drivers that were supposed to be written to my USB stick if I had installed Windows 7 using Bootcamp in the first place... However I think the message it said was that it couldn't install as it was the wrong version. So I'm still stuck without drivers and therefore no internet.
And that is my main task - getting the Internet up and running in Windows 7.
Other Info:
I'm running Mac OS X 10.6.8 with 2 GB of memory.
I installed the 32-bit version of Windows 7 and I don't know what version of Bootcamp I'm running...
I can tell you that BootCamp Assistant is v3.0.4, but don't know if that means Bootcamp is also 3.0.4.
Hope you can help.
Thanks.I tried something that worked for me...
Knowing that after my install of Windows 7 wasn't the correct method (didn't go through bootcamp), and the BootCamp 4.x package wouldn't install under windows 7, I tried reinstalling Bootcamp 4.x in Windows 7 to see what the exact message was it gave me. The message said it couldn't install because of a 32-bit O.S. vs a 64-bit version of the package.
So that got me thinging - my XP version was 32-bit, and so is my Windows 7 installation. So I tried installing the bootcamp that came with my Mac OS X installation CD. This is bootcamp version 3.1.
Not only did it install, but it practically took care of everything driver-wise for me. I was then able to see my wireless network, enter my password and I was connected. The only thing else I had to do to get on the Internet was bring IE8 online (guess it ships offline by default). Firewall and Antivirus are now installed, just a few more things to go.
That's one thing that's just not clear that I'll be sure to note for next time... The Bootcamp packages you download are actually driver packages for Windows. That is where the Windows drivers exists that are necessary to make your Windows 7 PC work on a bootcamp partition!
I didn't need the AirPoirt Utility at all (at least, I never went into it).
Thanks VikingOSX for your post. I will not need to follow the steps you provided, but they may help someone else as all of these bootcamp issues I've been reading seem to be very unique per installation.
Hopefully my solution helps others. -
Problem switcing Mac Mini HDMI via an Onkyo 606 Receiver
I'm having problems when attempting to switch my Mac Mini HDMI via my Onkyo Receiver. Connecting via a DVI to HDMI converter. Works fine when connected directly to the TV.
When connected via the Onkyo, I get the Apple logo at the begining of the boot-up process, but when the screen would ordinarily switch to my desktop background, the screen goes blank.
Any suggestions?
John.Do you have a second computer at your disposal? In cases like this, the best debugging method is to use a second computer and create a screen sharing setup under OS X Leopard, or a VNC set up if the second computer is not a Mac running Leopard. That way you will be able to see exactly what the mini is doing, even though the TV is blank.
Probably, in the end, you are going to need something like Gefen's DVI Detective to get HDMI switching to work the way you want it to. -

Editting PDF documents that were created by a MAC doesn't work because of font incompatability. How can we get MAC fonts and load in our Adobe Acrobat Pro 9?
If it's a Mac font and you're on Windows, you can't. If you are also on a Mac, you'll need to purchase the fonts (fonts are generally non-transferable, like software. One of the reasons pdf exists), install them and try your edits.
But it's best to edit the original document and create a new pdf when finished. -

Can mac mini use macbook's display?
Can mac mini use macbook's display? ie can it be added to Macbook as another drive?
No, it can't use the drive, but it can use the drive. You need a FireWire cable, plug them in to the same port on each device, and hold down the "t" key on the MacBook. The Mac mini should then see it as a hard drive. If you want to share the disc drive, on the MacBook open System Preferences, sharing, Remote Disk. In Finder, the Mac mini should see the MacBooks drive under "Remote Disc".

The new Thunderbolt technology in Mac mini is phenomenally fast. It features two 10-Gbps channels for data transfer. That’s up to 12 times faster than FireWire 800 and up to 20 times faster than USB 2.0. But beyond speed, Thunderbolt technology gives you unprecedented expansion capabilities. You can daisy-chain as many as six Thunderbolt peripherals, including the new Apple Thunderbolt Display. And since Thunderbolt is based on DisplayPort technology, your Mini DisplayPort devices plug right in, too.

How can I get Mac mail to open winmail.dat attachments on lion 10.7.3
How can I get Mac mail to open letter attachments winmail.dat?? (Lion 10.7.3) Any help appreciated...
Sorry peterskine,
it's true in part. There's more then one article on the subject "Recipients receive a winmail.dat attachment":
http://office.microsoft.com/en-gb/outlook-help/recipients-receive-a-winmail-dat- attachment-HA010153018.aspx?CTT=1
The odd thing is that my colleague and me use the same release mountain lion and we received the same email from someone on Outlook2007. He received the mail with the attachment, whilst I saw a "Winmail.dat". It already happened to me on snow-leopard, some month ago. Up til today I don't know what the difference between our machines is.
But it is interesting: the same OS, the same mail-clients (Apple Mail) and still different results.
Note: on my machine it used to work properly. It just suddenly happened that I started to receive winmail.dat files in stead of proper attachments.
When I have more time on hand, I cant try to find out why this happens.
