Possibility to use new Mac mini with an USB-DAC?

Anybody knowing anything about the possibility to use the new Mac mini with an USB-DAC. My reason for the question is that I've heard that USB3 doesn't handle sound. I'm thinking about to buy a mac mini and use it as an HTPC and signalsource together with NAIM DAC-V1.
// Rode orm

What I have heard that there are a few USB2 audio devices that
have had some issues with USB3, but USB3 itself is supposedly
backward compatible to USB2.
I would check with the makers of the DAC to see if there are any
USB3 issues.

ITunes on new Mac mini not recognizing my 1st gen iPod

I just got a new Mac mini. It has iTunes v6.0.4. My 1st generation iPod is v1.5. When I buy a song and attempt to transfer it from the 'Purchased' folder to my iPod, I'm getting an error message that says, 'Some of the songs in the iTunes music Library were not copied to the iPod because you are not authorized to play them on this computer.' Do I need to plug my iPod into the computer I was using before and click on 'Deauthorize Computer' before I try to use this one?

Mac Mini not recognizing USB optical drive - when Windows 7 in the drive

This is a really strange situation. I purchased a DVD writer in order to install Windows 7 on my Mac Mini (the SuperDrive stopped functioning some time ago). I've been able to boot from this optical drive to install Snow Leopard, but the Win7 disk isn't recognized when I try to boot from it (just get the folder with the "?"). Holding down "Alt" just shows me the Macintosh HD. I've tried multiple DVDs, including a genuine MSFT printed one with no success. I've attached this same drive to my Lenovo laptop and it booted to Windows 7 setup without a problem.
So, to sum up:
The Samsung DVD writer:
* boots up Snow Leopard on the Mac Mini
* boots up Windows 7 on the Lenovo laptop
* fails to boot Windows 7 on the Mac Mini
The Samsung model is Super WriteMaster Slim External DVD Writer, SE-S084
Any help would of course be greatly appreciated. Chocolate is possible for a really good answer.

Hello hoppingboy,
Just an FYI for you.
It is always best to check with the software manufacturer FIRST. They will tell you if they have tested the product and the version, as well as whether or not it will work with Windows 7.
Check out the Windows 7 Compatibility site: (There you will find out about hardware and software compatibility.)
http://www.microsoft.com/windows/compatibility/en-us/default.aspx
There is a pulldown from which you can choose "hardware" and "software".
There are also some great articles, instructional videos and such to help with your Windows 7 at our Springboard site:
http://technet.microsoft.com/en-us/windows/default.aspx
In any event a lot of the times, Vista drivers will work in lieu of Windows 7 drivers, however, it's not 100%!
As stated previously, it's best to have the Windows 7 certified drivers installed.
Thanks again,
John M.

Mac mini not recognizing USB mouse and keyboard upon boot

hey guys, i have a 2.4GHz mid-2010 mac mini with 2GB of ram, running 10.6.8 with all software up to date. this computer was purchased about two months ago. when i boot the computer, it does not recognize the USB keyboard or mouse though each is powered by the USB ports. oddly enough, after waiting for about 5-10 minutes, the keyboard and mouse magically begin to work normally and anything i did while they were both "frozen" happens all at once.
any ideas? i've done an SMC reset to no avail, tried other USB keyboards/mice, and i am unable to reset the PRAM because the keyboard doesn't work while the computer is booting. thanks in advance.

yeah, i did all of that; former tech here. i might just nuke it and start over, i wanted to post and see if anyone had the same issue. bizarre thing is that it actually DOES recognise the peripherals and they start to work after about 5-10 minutes, 'remembering' everything i did while it was semi-frozen. i.e. the mouse starts clicking everything i clicked, the keyboard logs all keys pressed, and everything happens all at once as it 'wakes up'. haha. one of my co-workers told me that the girl before me who was using this mini wasn't too bright and had that whole macdefender thing happen so it might be some residual leftover from that.
it also takes a pretty long time to boot so i'm suspecting it may or may not be something hardware-related.
thanks for your response!

HP P1102w and new Mac Mini not talking...

Hi All,
This is a similar issue to all the other threads involving the P1102w and Lion. It is a little different in that the printer is already on the network and running successfully with 2 other minis, 2 iphone 4s, and 2 ipad2s... it just wont work with the new mini.
I have read over many threads and seen lots of different answers and solutions but I didnt want to just jump in and start messing things up when there is (maybe) a simpler fix.
I know that the printer firmware is up to date, at least to a month ago when I installed it the first time. I do have a windows laptop if the solution is to do the HTML config I saw in another thread.
So, if anyone can point to the solution to this isue I would be forever greatful.
Thank you for your time in this matter.
Cheers,
Alex

New Mac Mini, Not so new LCD HDTV Monitor, no mac support

I have been attempting to set up a Mac Mini with a Maxent LCD 26" HD TV I can't get either the RGB or DVI-D input to accept signal. I have purchased DisplayConfigX and SwitchResX_X. Maybe they could work, but I can't get a signal to stay on long enough to change the settings as listed in other posts. I have tried booting in safe mode as DisplayConfigX instructions suggest. But still only am able to see the screen until gear starts spinning with apple logo, resolution changes spontaneously to one that I suppose is unsupported and I get the unsupported display and a beautiful blank blue screen. I tried manually inputting the resolutions the monitor manual lists, while connected with an lcd pc monitor. But I can't get the Maxent LCD TV monitor to stay on. It appears that if I could get the Mac Mini to send this resolution signal to the Maxent I would be able to delete any unneeded settings and that would be it.
Perhaps Tom Fussy can help me.I have been at this for over two weeks now. So I have become super frustrated. Of course Maxentusa.com offers no Mac support. But state that if Mac mini is supposed to work with PC that it should work with my Mac Mini. My LCD TV is about 6 months old I could still return it for maybe a Sharp Aquos, if that $300 dollar more TV would work. I am happy with the Maxent otherwise. Keeping it, and having it work with Mac Mini Is my choice. Of course Apple offers no support for the Maxent monitor and directed me here. This is my first discussion group post. School me if I have not followed the rules completely.

I was able to get the settings for Maxent using Gregory's software to force 640x480. Here are my settings

New Mac Mini not seeing my Apple TV

I just got a new Mini and used the migration assistant to migrate my accounts and files from my old Mac to the new one.
However, when I launch iTunes, my AppleTV is not showing in the left-bar or the Preferences. It used to show and sync just fine with my old Mac (G4 MDD Dual 1.25GHz).
I have the latest update running on the AppleTV (3.0.1) and am running the latest Mac OS (10.6.2) and iTunes (9.0.2). My library is still named the same, since I migrated my old account settings.
Is there anything I need to reset/change for iTunes to see the AppleTV?
P.S. I have "Look for Apple TVs" checked in the iTunes Preferences.
Thanks

Go to your TV menu and reset the synch for the new computer. I had the same problem when I got a new Mini. Not sure if it is due to the new computer or Snow Leopard. Even though the library & network names are the same, seems the TV knows the computer itself is different. Kill the current synch & set up a new one just like you did when the TV was new. You can use the same names. You will get a new pass-code to enter on iTunes when you do. The big negative is everything on the TV is dumped and has to be re-synched. If your library is very large, do it overnight.

IPad mini not recognized by itunes 10.6.1 (7)?

Why is new ipad mini not recognized by iTunes 10.6.1 (7)? Running OSX 10.5.8 software on the Mac. Software updates both report: "up to date"

Sorry, but you need iTunes 11 which requires OS 10.6 or higher and a Mac with an Intel processor. In other words, you need a newer Mac.

Can the new Mac Mini run OSX 10.7.5?

I have the new 1.4GHz Mac Mini w/4GB Ram. I bought a Mediasonic external 4 bay drive. It's connected by USB 3.0. One of the drives in the enclosure is my old HD with Mac OSX 10.7.5 installed. I've tried booting up from that drive through the USB 3 connection with no luck. Is it an external drive issue or does the new Mac Mini not support that old of an OS? Any thoughts are appreciated. Thanks!

Not outside of a product such as VirtualBox, Parallels Desktop, or VMware Fusion; Mac OS X 10.7.5 doesn't contain the drivers needed to boot that Mac model.

New MAC Mini w/OSX Lion - will not boot from USB or external optical drive when attempting to use BootCamp to install Windows 7?

The University recently purchased 6 brand new MAC minis for deployment in classrooms I support. I am attempting to create a dualk--boot environment comparable to our existing computer systems, only these machines wil be running MAC OS X Lion and Windows 7. After following the procedures outlined in the BootCamp on-screen prompts, and attempting a few techniques I found in the tech support user-base, I am still unable to get the MAC mini to boot up from the USB flash drive, or from an external optical drive, so that I can complete the installation of Windows 7. When using the Boot option key at start-up, all devices are displayed suggesting that they are being properly recognized, however the computer boots to a black screen with an error message indicating that "No bootable devices are found - press any key to continue." I am able to boot into the computer's internal drive, but not from any external devices. I fully expected that the semi-automated BootCamp procedure properly prepares the USB device for booting, and for installing the Windows 7 OS.

Meh, with the price they take for a drive in Denmark, I don't think it's worth it... They take around 160 $ for the drive (that's the cheapest MacBook drive I could find), and I am not even sure that's the one I need.

I just bought a mac mini over the weekend. I saved items from my old G4 to an external hard drive. I go to plug in the external hard drive and the new computer is not recognizing it. Help.

I just bought a mac mini over the weekend. I saved items from my old G4 to an external hard drive. I go to plug in the external hard drive and the new computer is not recognizing it. Help.
Here is the information I have. The external hard drive is a 120GB Acomdata. It has both USB and Firewire. When I go to plug in to the mac mini through USB, it is not being recognized. When I switch to Firewire on the old computer I can see it, however when I go to USB it is not being recognized (even on the old computer).
I'm at a loss as to what to do. Any advice would be helpful.

Have you ever tried the FW 400 to 800 adapter?
I have used them on multiple occasions and they work just fine.
Try this (maybe you already have):
-Boot Mini with drive disconnected.
-Do not connect drive but turn it on
-wait a few seconds for drive to spin up
-plug cable into the Mini then into drive.
This is an old drive and may have some timing
issues.
I had an Acomdata drive a long time ago. It
worked fine with FW but USB was flakey.

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

My new mac mini does not see usb drives, but in hardware info the usb is visible

my new mac mini does not see usb drives, but in hardware info the usb is visible
i'tried several usb flash drives even brand new ones, they are visible onder hardware info but they are not on the desktop nor in the finder.
what is wrong and doe anyone has a solution ?

It does not show up in disk utility, its only visible through systeminformation.
When you plug in the USB flash drive and then refresh systeminformation it becomes visible.
To remove it I shut down the computer because I cannot eject the USB device anywhere.
After starting up again when I have removed the flash drive it has gone from the systeminfo USB list.
By the way my USB mouse and keyboard are working fine, I also changed ports of these and they still keep on working so I don't think the USB ports are defect.
I guess it some kind software problem, and because I'm new to Apple I do not know much about it how to solve this.

New mac mini system will not recognize wireless keyboard and trackpad.

My brand new mac mini system will not initialize properly. The return on the track pad are not being recognized, although scrolling is. Any others find this? Support could not figure this out on the phone. They sent me out to get new batteries and now they are closed. Batteries have been changed and still nothing.

My Mac MINI gave me one heck of a time trying to get it to recognize my Bluetooth mouse and keyboard. both Apple brand.
I finally had to connect an old USB mouse and keyboard to get the silly thing to connect.
Don't forget to repair permissions.
I also had to shut the computer down and start it back up a couple of times before it would connect. I think it has to do with the new Bluetooth 4.0 wireless technology.
I also turned off my Bluetooth devices and turned them on again, then I pulled the batteries out a couple of times and tried again and again.
I also put in new battries even thiough the ones I replaced were about a week old.
Finally, the MINI recognised the mouse and keyboard.
I wish I could tell you which thing did the trick.
