Mac Mini, No USB or HDMI

I set up my new Mac Mini server last night, keyboard and mouse worked a treat, monitor worked too. Today it starts up with no chime, LED is on, I can hear the drive spinning but nothing on the monitor (via HDMI to DVI cable) no keyboard input nor mouse input. AppleCare guy says tomreset the PRAM but no can do without keyboard input. I'm stumped.

If the monitor is not working, the keyboard and mouse
might be working, you just can't see it. Starting up
without the chime is a little disturbing though.
Without a startup chime, you won't be able to tell
when to press the keys for the PRAM reset.
Another idea, hold down the option key or
"command + r" when you turn the Mini on.
With the option key, it should startup and show
a choice of bootable volumes. The "command + r"
should boot into the Lion recovery partition.
Try both, then can go from there.

How can I share external devices connected to my Mac mini via USB on a wired network.

Own a Mac mini with Mountain Lion. Purchased the server app. The Mac mini is connected to a wired network with Mac’s and Windows machines. I have an external hard drive and 2 printers connected to the MAC mini via USB. I would like to share these devices with other computers on the wired network. Although I have attached similar devices with an airport extreme in the past, I am unable to use a wireless router in this case. Any suggestions on making this work with my current setup?

You don't really even need server app to do this. Simply go to System Preferences | Sharing and turn on both File & Printer sharing. Then, for example, the printer (not relevant what connection it has but obviously USB is fine) will be available to everyone on the wired network.
That's all there is to it - unless I missed/misunderstood something re: your setup which seems very straightforward.

Install Windows 7 on a Mid 2010 Mac mini using USB or SD media?

Is is possible to install Windows 7 on a Mid 2010 Mac mini using USB or SD media? I have not figured this out. Here's what I have observed:
I can install OS X Lion using USB or SD media. Both are detected in the boot menu, and will boot.
An SD card with Windows 7 installation files formatted MBR/FAT32 using diskpart appears (with an SD card icon) in the boot menu but when selected as a boot device, the boot fails and the existing OS X instance on the Macintosh HD starts. A USB stick formatted as described does not appear in th boot menu at all.
An SD card or a USB stick formatted as described will boot on a Mid 2011 MacBook Air, and can be used to install Windows 7.
Is this due to EFI differences between a Mid 2010 Mac mini and a Mid 2011 MacBook Air?
Thanks.

The Mac Mini Mid 2010 has a DVD player built in, you can startup and install from a Windows 7 DVD. The Mac Mini Mid 2011 does not have a DVD player built in. I am happy that in new computers I can make use of an USB-stick to install Windows 7. Windows 7 uses MBR and Mac OS X uses EFI and that is why it was not possible on a Mac Mini Mid 2010. I think the EFI on a Mac Mini Mid 2011 is different.
I should like a firmware update on my Mac Mini Mid 2010 if possible. In that case I could choose between DVD or USB stick if I want to install Windows 7.
I also have a FireWire CF Card Reader. I think it is not possible to install Windows 7 via FireWire too.
I do have an external USB HD with 2 partitions: Mac OS X 10.6.8 and Windows 7, but is is not possible to start up Windows 7 from the external HD. It is possible to start up Mac OS X 10.6.8 from the external HD on a Mac Mini Mid 2010.

Mac Mini and USB 2.0 hubs (hubs stop working within a month)

I have an aluminum Mini running OSX 10.6.6 (Snow Leopard). With only 4 USB ports, I have need of a USB hub to accommodate my external drives and other peripherals: keyboard/mouse, camera and iPhone have to use the existing ports in the Mini (difficult access to ports due to space limitations), leaving one port for up to 4 external drives (older drives 40-60gb used for backup and extra storage).
I have problems using powered USB 2.0 hubs with this computer; I have 'burned out' 2 hubs since buying the Mini in February. They just flat out stop working, though they still show power (the power indicator light on the hubs); no peripheral is recognized when plugged into the hub (which worked fine for about a month). I can unplug the 'must use Mini ports' (camera, iPhone, charger, etc) and the peripheral drives are recognized and work normally when plugged directly into the Mini ports.
One hub was a Belkin 4-port hub (about 1 year old) and the other was a GE 3-port hub with several flash card readers (19-in-1 card reader), also about a year old. Is there any reasonable explanation why powered hubs would suddenly stop working, related to use with the Mac Mini 2010 aluminum version?
I had worse problems with the USB ports in an old (~2006) Mac Mini (out of warranty), where the USB ports in the Mini stopped working, which is partly why I bought the new mini. In light of this tidbit, (be honest, please) are there known issues with Mac Minis and USB?

Each of the external drives has its own power supply; I generally only use one drive at any one time, but on rare occasions I have powered up more than one to confirm or transfer files. I don't leave any of those drives on when not in use, and when everything is working I properly eject/unmount them before turning them off.
There have been times when I powered up a drive connected to a powered hub and both the hub and the drive indicated activity but the drive didn't mount. On those occasions the drives sometimes would not appear in Disk Utility, and other times would appear, but would not be "mountable". I didn't know what the best way to deal with that was, so I would just turn the drive off, hoping the lack of mounting on the desktop meant no real drive activity was occurring and I wouldn't risk data loss or drive damage. So far all the drives seem to work fine when plugged directly into the back of the mini.
The main external hard drive I was using when the Belkin hub failed (iomega 40g) is USB 2.0 only (no firewire). I have another drive that is only firewire (la cie 60g)... so it wasn't a factor. Two other external drives are ACOM, one 40g one 120g, and then there's my old iMac G5 disk (display fizzled and everything but the disk recycled through Apple's recycling program) which is mounted in an external enclosure and is part of the USB contingent, but is not being used for anything but backup (all three both USB 2 and FW400 capable). (I know, too many toys... but why throw them out?)
The USB hubs both had their own power supplies, too, and I never used them without power (though I tried it as part of troubleshooting, before reading the Apple article on USB and power requirements). Other USB devices that only work when plugged into the mac directly are my Epson Stylus CX4800 all-in-one, and my Radio Shark.
So, whaddya think? Should I risk buying another powered USB hub or just live with plugging in peripherals to one available USB port (through a short USB 2.0 extension) and only use one at a time? That would be a bit of a pain, but if there are no issues you've heard of with Mac USB ports (several unanswered questions in the Mini Support forums here involving USB and peripherals, I noticed), what else would explain the seemingly short lives of USB hubs?
Oh, here's something I just remembered: the last time the Belkin hub was working (last night), I had my Radtech BT mouse charger cable plugged in (not charging, mouse not attached) along with two of the external hard drives, and my Fuji camera USB cable. I got an error message onscreen (on the Mini) that a drive had been improperly ejected (or put away?), yet the hard drive in question was still mounted on the desktop. I looked at the hub, and the loose ends of the charger and the camera USB cable were touching. Could that have caused the error (and maybe the hub to fail)? (Edit: the camera cable I think was plugged into the mini's one available port; 3 external drives and the mouse charger were plugged into the hub, _but only one drive powered up and in use (3rd edit)_. The camera end of its USB cable contacted the mini-plug end of the mouse charger... could that have short-circuited the hub? +That wouldn't explain the failure of the GE hub a couple weeks before... but I don't know if any of this is connected, so to speak--2nd edit.+)

Can't reach network video server on Mac Mini's USB Ethernet Adapter.

I am trying to connect an IP video server to my Mac Mini's USB>Ethernet adapter. The server works fine on the built in Ethernet "en(0)", but is unreachable on the USB>Ethernet adapter network"en(3)".
Is this a subnet issue? I don't know much about networking obviously, but I think I just need to find a way to designate the proper port to look on, because the Mac is looking on the built in Ethernet only when I specify http://192.168.0.90:80/
The en(3) is configured for DCHP.
I could just hook the server up to the built in Ethernet, but then I'll have to run new and very long cat 5 cable.
I'd love to hear any ideas on how to get this working.

The Network Settings for the USB>Ethernet port are:
IPv4: Using DHCP
IP Address 169.254.33.152
Subnet Mask: 255.255.0.0
Router: (none)

Mac Mini KVM USB problem prevents boot when using certain USB ports

Hi,
Just purchased a brand new Mac Mini 2.4 Quad Core to use as a server.
This morning we removed from the box & connected it to our NTI Unimux 16-port KVM. The KVM already has 10 Mac Mini's connected (various vintages, no problems).
We connected the Mini to the KVM using HDMI for video and a USB connector.
The Mini initially refused to boot past the initial white/gray screen. It never got to the Apple or the cog.
However, we found that if the USB cable from the KVM is disconnected, the Mac Mini booted immediately.
Further, the Mini will also boot with an Apple keyboard connected.
So... you may assume that the KVM cable is bad or that there is some firmware compatability issue between the KVM and this new Mac Mini.
EXCEPT...
This Mini has 4 USB ports.
We found that the Mac Mini can boot with the KVM USB cable connected if the USB cable is connected to USB ports 2 or 4 on the Mac Mini.
If the KVM USB is connected to ports 1 or 3 on the Mini, the Mini will not boot.
The Mac Mini will boot with an Apple USB keyboard installed on any port.
Is there any logical reason for this behavior?
Thanks,
b

G4 mac mini via dvi to hdmi problems

I am trying to get my g4mac mini to work via a dvi to hdmi cable to a new sony lcd screen kld-46x2000. I can connect ok via the vga/pc input but the max resolution the lcd will support with the pc input is 1360x768. It is supposed to be one of the new true1080p screens that will support 1920x1080@60hz via the hdmi input. All I get when I try is a black screen and a message saying unsupported signal. Any ideas on how I can get this to work?

Assuming you actually have a KDL-46X2000, the manual clearly states that PCs should be connected to the PC input, so it sounds like Sony doesn't support what you are trying to do. And Apple of course doesn't claim the mini will work with all DVI displays, just most of them.
The G4 Mac minis are notorious for having issues with DVI-connected displays. You might try a third party application like SwitchResX to try and get the video settings to agree with your Sony.

Mac Mini to Toshiba 32C120U (HDMI to HDMI) problem

My Toshiba 32" 32C120U is not getting video signal from my Mac Mini. I bought the Mini for my son and this is his TV. I have hooked up the Mini to my older 22" Toshiba and my 56" Samsung with the same HDMI cable and it works great on both. What the heck is wrong with my son's 32" Toshiba? I have called Toshiba customer support and they won't help with my question without a $35 charge because I'm just out of the year warranty . . some customer support that is !!! I really don't know what they would be able to tell me other than thanks for your $35 and sorry we can't help you. I did update the firmware on the TV and the Mac Mini has been completely updated as well.
I have also tried both HDMI 1 and HDMI 2 ports with his Xbox with success, so both ports work. I have also tried both ports with the Mac Mini and there is "no video signal" on both ports. I noticed that when I hooked up the Mini to the other TVs it automatically selects the best video setting, so there is obviously some communication that happens between the Mini and TV, but that is not happening with my son's TV.
Any suggestions would be greatly appreciated.
Thanks in advance,
John

Mac mini, macbook + DVI to HDMI + projector = No soup for you!

This is driving me nuts!!! I have tried 3 different macs, 4 completely different cables/adapters and they all do exactly the same thing.
1. I connect the mac to the DVI to HDMI cable and/or adapter combo, then connect to the projector
2. I get 2-30 seconds of wonderful projector screen usage (it works, picture looks crystal clear)
3. Then POOF! No projector signal, though it appears mac recognizes the projector.
I can repeat from 1 using a different adapter and/or cable and I get exactly the same results, but if I re-use the same cable I used previously, I get no signal at all.
What the $%@! is going on here??? Is Apple black-listing my cables or something??? I'm using everything from cheap-o cables to $$$ cables with exactly the same result.I run this projector with absolutely no problem from a dell desktop via DVI to HDMI.
For what it's worth, I'm connecting to a LG HS201 projector.
using Core-2-duo macs either with pure DVI or mini-DVI

DVI to HMDI is not supported on the Core 2 Duo Mac Mini.
You need to connect via DVI or VGA to your projector.
I have had Core2Duo Mac minis working with Sony LCD TVs and a Toshiba Plasma via DVI to HDMI cables with no problems. Obviously audio has to be run separately. There have been many reports from others that this works. It should do since both DVI and HDMI support HDCP and both are digital video connections, this after all is why a simple DVI to HDMI cable works.
What can be an issue is if your trying to do things like 3D or YCbCr colour encoding. However standard video works fine. Another common issue is if your are switching inputs to the TV perhaps via an AV Receiver or if the TV is allowed to sleep or be turned off, in these cases the Mac can see the handshake signal disappear. It is for this sort of situation Gefen makes the DVI Detective+ and the HDMI Detective+.
Since in your case the common factor is your projector and not the computer or cables it might be it at fault. Early HDMI products did have HDCP handshaking problems.
People have been using Mac minis as media center computer with HDMI for ages since the Mac mini is small and quiet, this probably goes back as far as G4 models let alone Core2Duo models.

IDVD 7.04 on Mac Mini (Late 2009) Connected HDMI to 46 Toshiba LCD

I suspect that there is a video setting that is wrong, but has anyone been able to get iDVD to not crash with the hardware connection in the subject? iDVD keeps crashing right when I am ready to add videos to my project.

sounds like an awesome setup. Unfortunately, only one of my two monitors has an HDMI input. Also, even when hooking up just the one with HDMI to my Mac mini, it still displays "no signal" and I have two different converters I've tried. Perhaps it's just not meant to be. I will have to settle with DVI connections for both monitors...not the end of the world. I shouldn't complain.
Thanks for the quick answer and advise.

Mac Mini Audio Intermittent over HDMI, Cuts out with Assertion in kernel.log

Hello. I've been having trouble with a mac mini (Mid 2011) that I bought on Thursday. It's running OSX 10.7. The Mac Mini is the $599 unit.
I've got it hooked up to my Sony BRAVIA HDTV (also this year's model) via HDMI, with audio configured to be delivered via HDMI to the TV alongside video. Initially the audio will play through my TV, but after an hour or two of watching something, it will cut out, and there will be no more sound coming out of the TV from the mac. Ultimately, the only way I can fix it is to reboot the Mac Mini. I've also observed that at about the same time sound cuts out, the following error message appears in kernel.log:
Aug 12 19:21:40 joshs-Mac-mini kernel[0]: Sound assertion "0 != result" failed in AppleHDAWidget at line 3957 goto handler
Aug 12 19:22:10 --- last message repeated 5 times
As far as I know, assertions failures usually mean software problems (bugs). I suspect I may be encountering a kernel-level bug in Lion, as this error message is showing in kernel.log.
The following is a list of diagnostic steps I've taken:
- I've double-checked the sound output device in preferences. It didn't spontaneously change from SONY TV (HDMI) after sound cut out.
- I've tried changing output to the internal speakers. It plays sound from the mac mini (as expected). When I change it back to HDMI, still no sound from the TV.
- I've tried turning off and back on the tv. No effect.
- I've tried unplugging and replugging the HDMI cable. No effect.
- I've tried replacing the HDMI cable with two other alternates. No effect.
- I've tried other HDMI inputs for my TV with HDMI attached. No effect.
- Note: I've got a ps3 and xbox360 on the TV that has successfully used the HDMI inputs and cables tested on. They've never had this type of problem, so I don't think there's a problem with the TV.
- I've tried rebooting the mac and resetting the "PRAM" (Command-Option-P-R before the grey screen on bootup). Sound still cuts out after a while.
- All updates are applied.
Does anybody else have any ideas about what I could try to fix this? This problem is pretty much a deal breaker, as rebooting the mac mini mid-movie kind of destroys the movie-watching experience.
Thanks

I'd just like to jump in on this thread to report exactly the same problem.
2011 Mac Mini (the 2.5GHz i5 model) running Lion, Sony Bravia TV, HDMI sounds cuts out after a while with the console error "Aug 15 18:30:25 Mini kernel[0]: Sound assertion "0 != result" failed in AppleHDAWidget at line 3957 goto handler".
Interestingly, after the error occurs, I can still get 5.1 sound through Plex, but not through Quicktime. 2.0 sound and system sounds all fail until I reboot the system.
Any help would be appreciated. I would prefer not to have to return the Mini.
Thanks.

Mac Mini does not display HDMI 1080i in full screen on TVs

I have a 1.66 GHz Intel Core Duo Mac Mini that I am having problems getting video to display 1920 x 1080 @60hz in full screen on my Sony XBR 1080p HDTV. The Mac is connected to the TV via a DVI to HDMI cable. The Mac recognizes the display as a "Sony TV"
When the Mac first starts up the entire TV screen is filled with the grey Apple startup screen, but when the Mac fully boots and gets to the desktop, the screen has shrunk so that it is slightly off the screen on the left, and has about 80% of the screen filled horizontally and about 90% vertically. I have tried all combinations of the overscan selection on the Mac and on the TV, but they make the image about 120% of the size of the screen so the top, bottom and sides are cut off.
I have tried 2 different 1080p HDTVs with the Mac Mini and get the same results for both TVs.
Now here is the thing that makes me believe that there is something funky with the Mac Mini. If I take my 2.16 GHz Macbook Pro 15" Intel Core 2 Duo and plug its DVI display port into the Same DVI to HDMI cable that is connected to the same Sony TV, it displays full screen with no problems.
What can I do to make my Mac Mini display properly?

Thanks for the ideas.
I did as you suggested, but the only 1920x1080 selection shown was one for "NTSC" which I would think is interlaced. This was after a reboot. All of available resolutions are labeled with "NTSC". When I look at the screen resolutions on my MacBook Pro when it is connected to the TV, they are labeled as "Interlaced". On both computers there are no progressive scan selections.
As an interesting note, regardless of what display resolution I select, the display area on the TV screen remains the same which is about 80% of the screen offset to the left. When "overscan" is selected, this mode enlarges to image to about 120% of the screen and cuts off the menu bar etc. However the MacBook fills about 98% of the screen in "normal" mode.
If there was a less aggressive Overscan mode or more aggressive normal mode, that would fix the issue.
Any other ideas on how to adjust this?

Strange mac mini sound issue with HDMI cable

I connected my mac mini to my Panasonic 44 inch HDTV with a DVI to HDMI adapter. I didin't get sound through the cable like i expected. Then I connected a 3mm to RCA jacks adapter to the analog HDMI port on the TV and still no sound. Strangely, when i switched resolutions from 1920 X 1080 to 1200 X 720 the sound started working through the audio ports. It works on every resolution except 1920 X 1080. Any ideas why this is so? Or how to fix it?

First off, the DVI standard makes no provision for carrying sound. That is why you didn't hear any sound when making a DVI-to-HDMI connection from your mini to your TV through the adapter. I am assuming there must be a setting on your TV that is snuffing the sound input from the mini rather than the mini not outputing sound at 1920x1080. This would be easy to prove. Just pull the audio minijack connector from the mini's sound out and I'm guessing you will hear sound coming from the mini's speaker.
Is it possible that, on your TV set, you have associated 1920x1080 with an expectation of HDMI input? Maybe the TV is expecting to find digital audio over the HDMI input and somehow that association is only with that one resolution. Then when you drop resolutions it is looking for sound over the analog port instead of over the HDMI port. I'm just guessing here, but it's something you can check.

Connecting mac mini to USB monitor didn't work!!

I connected new Mac mini(2007 model) with the latest HP USB monitor. Nothing got displayed on the monitor. Then I need to connect mac-mini to another VGA connector monitor. But still want to know to connect USB monitor with mac-mini as this is my target setup.

Thank you.
I used Tiger OS specific drivers from the following link.
www.displaylink.com/support/mac_downloads.php
Now it's working but not 100%. Upon starting of the mac-mini monitor works fine. But later when I switch off and switch on the monitor, then it doesn't work. Looks like monitor off -on trigger is not handled in the driver.
I will check with the driver like you have suggest and then acknowledge.
