"No signal" on screen with new mac mini

Hi
I have just bought my first Mac Computer. When everything ist properly connected and I start the Mini, the monitor shows "no signal". The Mini ist switsched on and starts (light goes on). The Monitor is a 4 year old TFT with Analog port (white adapter neccesary to connect it to the MAc Mini). I tryed with another Monitor (6-year old Phillips) and the Screen still stays black.
Help would be highly appreciated.
Thanks

The fact you are getting the same symptoms with two displays suggests the mini or the DVI/VGA adaptor may be at fault.
I would suggest you follow the suggestions in http://docs.info.apple.com/article.html?artnum=300583 and if that doesn't help, since this is a new mini, call Apple without any further delay.
Note that in the above document it refers to resetting the PMU. This is something related to the earlier minis. For your Intel model instead of resetting the PMU, you need to try an 'SMC reset which is done as follows:
-Switch the system off
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.

The HDMI adapter that came with New mac mini, would fit on the connection coming from my old mini. My monitor has receptor same as the end of the adapter.

I found out that I have 2 female ends, my question is where can I find the adapter with 2 male connectors? and what about power supply to monitor?

Can I use an old Apple Cinema Display with new Mac Mini?

Currently I have an early PowerMac G5 that I bought used recently. It came with an Apple Cinema Display (20", I think - resolution is 1680x1050). The Cinema Display does not have a separate power cord so it must be powered from the PowerMac. My question is this - would I be able to use this monitor with a new Mac Mini - would it be able to power it the same as the PowerMac is currently.
Thanks in advance for your help. This is the first Mac I have owned since a "Fat Mac" many years ago (one of those with the 9" black and white screen).

Are you sure you have a 20" CINEMA display? I have 2x 20" CINEMA displays and both have their own power cord (and power brick). Maybe yours is a STUDIO display??? IDK if STUDIO displays worked that way or not, I've never owned one. Anyways, I have a 20" CINEMA display connected to my new Mac mini (early 2009) via the MiniDVI>DVI adapter and it works fine but is powered through the power cord though. I too have a PowerMac G5 (quad) but my PowerMac cannot power the displays without them being plugged in via their power cords. I am thinking you must have a STUDIO display or maybe there was an earlier version of the CINEMA display that could work that way.... idk. Mine were purchased at the end of 2005 along with the PowerMac G5 (quad).

Wireless Keyboard don't connect with new mac mini

Hi,
I just received my new Mac mini server 2011 and bought an Apple wireless keyboard (already have a magic mouse). At first start up of my Mac mini picks up my magic mouse and I can use it but does not pick up my wireless keyboard? Is this normal? Am I missing a trick with the keyboard? Do I first need to use a normal USB keyboard to configure my Mac mini and then when Lion is setup it will install the driver for the wireless keyboard?
Regards,

I just bought new Mac mini w/ wireless keyboard and track pad. During initial setup it would not pair to keyboard but it di see trackpad. I could not complete setup, I have no control. Brought home USB keyboard from work and resumed setup. I'm stuck again. In setup it's asking for a trackpad click to continue. The trackpad will scroll, but will not click. The whole system is two days old and nothing works I tried to contact support through the lengthy online screening process and apple ultimately say the new system doesn't qualify for free support.
Totally ******. I'm back to using my old pc.. What to do with this expensive boat anchor from apple?
Really could use some help here
Thanks

Quality issues with new Mac Mini 09?

I've been itching to hit the 'buy' button -- but in reading the many postings about the new Mac Mini, I'm seeing lots of issues with the bluetooth ... *wireless signal* ...
Is there anyone who's not experiencing any problems?
Sounds like it may be a hardware issue with connections... the last thing I want.
My other choice is the 2008 Mac Pro which seems trouble free.
What do you think?
Thanks.

There is a general issue/trend with the new Mini. There are plenty of reports in these forums and the news has begun to hit the wider press; I guess this is more important to a company with only 2-3% desktop share than posts to these forums. I went to the Genius Bar on Saturday and they have now lodged an official bug report with Apple. It looks like the Mini cannot pair with more than one HCI device. So if you pair with the mouse first the keyboard won't work and vice-versa. They don't think the Mini hardware is broken but that we will just have to wait for Apple to fix the firmware.
Where I do agree is that some issues are OS-X 10.5 related and can therefore affect all Macs. The WiFi has issues where it randomly drops, it doesn't seem able to re-connect at all to channels above 13 and only manually to channels below 12. The system resume function is unreliable. All these started when we moved from 10.4 to 10.5 and so far they have not been addressed. One issue is that there does not appear to be a way for users to log bug reports, except when software crashes. However, the bluetooth issues on the Mac do appear real and are either firmware or hardware related.

Atleast one freeze a day with new Mac Mini

Greetings all,
I'm a new Mac Mini owner, and am wondering if I should take it back, or is there some fix for this.
Everyday usually while surfing the net but I think I can be doing anything. The mac mini freezes, I can't move the mouse or anything and I think the clock even stops moving. Different times of the day. I press the power button once..and then press it again, and its not rebooting. But it comes back on with everything on the screen and the mouse moving. (so I'm pretty sure its not rebooting)
Is anyone else experiencing this problem? Should I take it back? Its a random occurrence when it freezes. So theres no way I could show it to apple.
Are there any tools to use to check this sort of thing out?
I really need your help!!

It does not reboot when I press the power button the screen just goes off, and looks like the wireless is disconnected (or my ichat just reconnects)..but it comes back to the same screen here. I just did it while I'm typing this note.
I wait about a minute to press the power button..I've waited enough for the clock to have changed and it does not. (but I'll make sure)
I'm using the wireless keyboard and mouse...which I assume connects over bluetooth. (I can eliminate this being the problem if I let it sit long enough and don't see the time change on the clock?)
Nothing else is connected, I am however using the same monitor to connect both my mac mini and my Windows Vista pc. Using mac mini (DVID) and VGA for my PC.
Thanks for your help on this

Got Lion with new Mac mini and want to install on imac

Hi,
I just bought a new mac mini with lion. and now i want to install Lion on my imac.
Is there a way to register my purchase of lion on appstore so i can download it from there?

You'll have to pay for the App Store version of Lion needed for the iMac. The license for Lion that you get with a new computer is different from the App Store license, and doesn't provide for multiple installations.

Can I use Dual Displays with New Mac Mini (HDMI Thunderbolt)

Hello Everyone,
This question may have been asked before... but I just purchased a beautiful new Mac mini and it has an HDMI port in the back and a Thunderbolt port. I am using a new DELL 23" HDMI monitor that also accepts DVI. I think I could run another monitor on the Mac Mini, but I don't know which is the best way to go... I purchased a mini-display port to DVI adapter because I heard thunderbolt could accept the mini-display cable.
1. Should I purchase the other identical Dell monitor and then run it on Thunderbolt 2 DVI and run it DVI
2. Or is there a HDMI splitter that splits the signal into two cables and go that way?
Any advice would be greatly appreciated Thanks!

I just got the mini server and run a 24" LCD off the HDMI port and a 19" off the displayport (adapter to DVI) and it works a treat there's no need for any splitter.

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)

Using ASD with new Mac mini

Can I use my 17" Apple Studio Display (LCD purchased in 2004)with a new Mac Mini?
Does HDMI port on a 2010 Mac Mini support the ASD LCD with a male 35 pin connector?
If so, I need an adapter with a female end for the LCD connector and a male end for the female Mac Mini HDMI port. Can't find an adapter with that configuration.
Thanks.

You would need a DVI to ADC converter. Apple used to make one (the Apple M8661LL/B DVI to ADC Display Adapter), but have discontinued it so they're getting hard to find. Gefen still makes a DVI to ADC adapter, I believe. You would then need either a mini-DisplayPort to DVI adapter, or an HDMI to DVI adapter.
A new DVI 17" monitor would probably be not much more expensive than the DVI to ADC converter, which run upwards of $100.
Regards.

Boot Camp bug with new Mac Mini?

OK, so I have used Boot Camp now for years, on a variety of Mac platforms, and I have always been able to set it up and run Windows, including Windows 7 64 bit. That is, until I purchased my new Mac Mini i7 (non server version) with the WD 750GB internal, with 8GB ram. As the new models no longer offer a built in SuperDrive, I purchased a Pioneer external Blu-ray drive and have it connected via FireWire 800.
I have a brand new retail Windows 7 64 bit installation disc and have downloaded and burned the Windows 7 drivers to a CD.
I followed the instructions implicitly, but always hang on the reboot that should go into Boot Camp and begin the Window 7 install. Instead, I get the dreaded "Boot disc not found. Please insert a bootable disc and press any key" error, from which there appears to be no return.
Anyone have any ideas or is this just a known bug?

This same message was displayed in my MacBook Pro yesterday when I partitioned the HDD, however in my case I hit the "Quit & Install Later" Option as I planned to install win 7 later. When I rebooted my Mac to my surprise it had defaulted to my DVD drive and could not find the disc (obviously, since I wasn't planning to install it). I remember that in SL this issue was not present. Ultimately, I had to hit the option key to boot back into OSX Lion and reset my Macintosh HD as my start up disk via system prefs.
As for your case I would suggest hitting the "option" key during start up and see if your Mac can recognize your Windows 7 disc. If it recognized select it with the keyboard arrow keys and when it is selected hit the "return" key. Then the Win 7 DVD should boot and then follow the instructions of the Windows 7 Installer.
My suggestion is to fill a bug report to Apple via their feedback section:
http://www.apple.com/feedback/macosx.html
As far as I know Bootcamp 4.0 is extremely buggy, yet I do think that OSX Lion overall is a very stable and snappy OS, I noticed that my system performance has not been that much impacted by it very much. My boot times went up by 3-4 seconds longer than SL and shutdown times went up by 1 sec only, as for app launch time they have remained the same. Hopefully further updates to OSX lion will address these and other issues.
Good Luck!

Sleeping issue with new mac mini

i have a new c2d 2.0 mac mini all software is up to date. the first night i was able to put it to sleep without any problems but since then when i try to put it to sleep by eithre the apple menu or hitting (eject,apple,option) the dvd drive clicks and the mini wakes up all in 5 seconds.
another sleep problem is with both mac mini's (the c2d and g4 1.42) neither will go to sleep with an external harddrive connected (mounted or not and still powered on) I have looked for an answer to this problem for a while and have found nothing. i thought i saw a thread on this very subject but have yet to find it again
thanks for help
Nick

Hello,
It's nothing to really start worrying about, it's most likely down to a communication error between your hardware and your software. The simple solution is:
1) Unplug all cables from the computer, including the power cord.
2) Wait 15-20 seconds.
3) Press and hold the power button on the back of the computer
4) Whilst holding the power button, plug the power cord back into the machine
5) Release the power button
6) Press the power button once more to start up your Mac mini.
Everything should be sorted! (if not, call back here)
Good luck

Unable to backup to external hard drive with new Mac Mini

I have been using a 1TB iOmega MiniMax external hard drive to backup my Mac Mini that was running on OS X 10.6.8. I recently replaced the Mac Mini with a newer model running on OS X 10.9.5. I successfully recovered all my files from the backup hard drive onto the new Mac Mini. However, since then I am not able to do either an automatic Time Machine backup or a manual backup. I'm wondering if I need to update the iOmega MiniMax driver to be compatible with the newer OS X. So far I have not been able to locate any updated drivers. The new Mac Mini is able to recognize the old data that were previously backed up, but will not complete a new backup. Any suggestions are appreciated.

Thanks for the help. When I got the new Mac Mini, I was able to restore all my files from the iOmega HD backup. But since then each time I try a TM backup I see the in work wheel spinning (in Finder) but no backup is made. No error messages are given. I will try the trouble shooting list you sent. Thanks again.
