No signal error with mac mini to acer monitor

I bought an Acer monitor and a Mac mini back 11/11 and it has worked fine. I recently moved the computer to a new room and when I set everything up I got a no signal error with the monitor and went to sleep mode. I have tried another monitor (viewsonic) and a new VGA cable and a new VGA to dvi converter to no avail.......any suggestiins....frustrating thing is both monitor and computer are working.

"See administrator" error with Mac mini airport card

Help, please. My Mac mini has an airport card installed. I got a new cable modem with a wireless N router (combo cable modem plus wireless N router) and I went to wirelessly connect my Mac mini's airport card to it.
I guess I typed the wireless router's password in wrong too many times or something, because suddenly I received the following airport error message on my Mac when trying to join the network (during the "The network so-and-so requires a WPA password" phase):
"See administrator."
It will not let me connect to my wireless network, even though my Macbook, my iPad, and my Roku player are connected to this wireless router/combination cable modem just fine. The Mac mini is connected to it through Ethernet.
Also, with my previous set-up, a wireless router (a Belkin N router) combined with a cable modem from my ISP, the Mac mini was connected at the same time both wired (Ethernet) and wirelessly (airport).
So I cannot figure out what is wrong and I cannot figure out how to clear this message.
I have already tried a solution that I found here which is indirectly related:
http://hints.macworld.com/article.php?story=20060318124936642
because yesterday I was also getting a System keychain error but I can't seem to reproduce that at the moment. I must have cleared that one, but I still can't access my wireless network through the Mac mini.
I am locked out of my wireless network on my Mac mini even though I have full administrative rights on my Mac mini.
Can anyone help me figure out this conundrum? Thank you.

I did find some keychain system files in Library/Keychain.
But in trying to access items in my Keychain Access, I get a message from Keychain Access stating, "Keychain Access wants to use your confidential information stored in "(name of wireless network)" in your keychain. To allow this, entre the "login" keychain password."
I then enter every password known to mankind and it doesn't accept any of them. This is me trying to access an Airport password that is stored in the "login" area in my Keychain Access. I do not know what the mysterious "login" Keychain password is.
Anyway, to go back to the main issue, I am locked out of my wireless network and get the mysterious "see administrator" error. That is the main error message to focus on. Thank you.

I can't use my Philips monitor with Mac mini

I can't use my Philips monitor with Mac mini, I am using a HDMI to VGA cable to connect them. But no signal on my Philips monitor.
My Mac mini is in a good condition, it can connect with my HDTV, the BENQ monitor at my office, but I can't make it connect with my Philips monitor.
I dun know what happen.
Please help!
Thanks!

The two are incompatible, HDMI is a digital signal and VGA is an analog signal. You need a monitor with a HDMI port or a DVI-I port, these are both digital signals. DVI-I gives the best output.

Can you use hdmi to rgb composite cable with Mac mini

I am thinkining of getting a mac mini .vI have a older jvc 2004 wit rgb composite conection .Can you use hdmi to rgb composite cable with Mac mini or do yo have to use a hdmi to composite converter to hook up to the tv wit Mac mini

12. Can I output via Mini DisplayPort to an RCA or S-Video connection?
No. The Mini DIsplayPort connector allows output to Mini DisplayPort, DisplayPort, VGA, DVI, and HDMI connections when using the proper cables and adapters. However, output to RCA, Component, or S-Video connections is not supported.
- The current Mini as one HDMI out. The Min somes with a HDMI to DVI adopter. Howver, the HDMI output only outputs digital signal and thus yo will need a converter to convert that digital signal to analogue composite
- The Min also comes with a Thunderbolt port which accepts the min display connector. However. based on 12 above it does not seem to support composite. The 12 is from

Audio input/output problems with Mac Mini

at first, my sound just stopped working all together and for some reason the monitor was getting no signal from the mac mini. i unplugged everything for a minute and plugged it back in and the monitor was working again, but still nothing with the sound. no sound coming out from even the internal speaker, and the audio in jack (which i use frequently) stopped working as well.
this is the really strange part: after tinkering around trying to fix the problem i realized the only sound that comes out it is from the internal speaker, but it only comes out when i have something connected to the headphones jack.
has anyone ever had a problem like this? i'm just trying to figure out if it is something i can take care of myself, or if i might need some repairs done.

OK, then two things to do.
First reset parameter RAM - it's an area of non-volatile memory used for system settings and hardware configuration. It it gets corrupted, it can cause odd problems.
Reset PRAM
-Shut down the computer.
-Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in the next step but one.
-Turn on the computer.
-Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
-Hold the keys down until the computer restarts and you hear the startup sound for the second time.
-Release the keys.
Next, perform an SMC reset. The SMC is the device which controls system hardware and devices, so if there is a problem with hardware components not functioning, it could be that.
To reset the SMC on an Intel mini:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns 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.

Toshiba 32C120U "no video signal" from my Mac Mini using HDMI to HDMI.

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 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

I solved my issue . . . returned the Toshiba for an Insignia . . works great.

Your advice did not help me. I also installed 10.7.4 combo but the situation is the same.
my internet connection is ok, mail is ok, but app store after 3 resets does not recognize my ID and it says "connection is not possible". Why? I have the same problem in both my mac mini late 2009 and mac book air 2010? Is it a problem of 10.7.4 update? I have to solve this problem and how can i return to 10.7.3 if my last backup was not with 10.7.3???thank you for your kind collaboration...

Dual Displays with Mac Mini

Hi,
I have 2 identical BENQ G2420HDB (24") displays, and am looking at getting a new desktop computer. My thought was to go with the Mac Mini but I need to ensure compatibility.
Currently one is plugged into my Mac Book Pro 2.33 (one of the first Duo Core 2) and it reports a natural resolution of 1920x1080 (Normal HD), and wish to use both displays with the new computer. Will a Mac Mini support both monitors as extended desktop in this resolution? If so what adapters (if any) do I need to buy with the Mac Mini? The inputs on the monitors are: DVI, VGA. Is there an minimum model of Mac Mini that I would need to get?
Thanks,
Michelle

Welcome to the Apple Discussions!
The Mac mini has two video ports; mini-DVI and mini-DisplayPort. The mini ships with an Apple mini-DVI to DVI-D adapter. You could also purchase a mini-DisplayPort to DVI-D adapter and then use DVI-D cables to connect the adapters to your displays' DVI-D ports. This setup can support up to 1920 x 1200 pixels, and can be configured in extended desktop mode.

The best audio interface with Mac Mini using new & existing equipment?

Hi,
I got my existing set-up back in 2003. I'm now about to update it.
I've talked to Apple Technical Support re which computer is best for me.
Some important questions remain in terms of the audio interface or sound bridge I should use.
I've detailed below my existing set-up, my existing configuration, my desired set-up (as recommended by Apple expert) and questions I have.
Existing set-up:
Hardware...
1. ViewSonic HDMI 1080p Full HD LED monitor
2. PowerMac G4 (PowerPC processor) computer
3. PCI-424 soundcard within computer (works in conjunction with MOTU 2408 mk3 unit)
4. MOTU 2408 mk3
5. Quested monitors
6. Focusrite Session Pack ff ISA220 compressor
7. MOTU micro lite (midi-usb interface)
8. Keyboard (yet to choose - I'll explain later)
9. ADK Tube Condenser Commemorative Edition microphone
10. ADK Tube Condenser Commemorative Edition microphone power box (supplies both power and phantom power)
Software...
11. Tiger 10.4.11 operating system
12. Logic Studio 8 music program
Desired set-up:
1. ViewSonic HDMI 1080p Full HD LED monitor
2. Mac Mini full spec = £999.00
3. _______________________________________
4. _______________________________________
5. Quested monitors
6. _______________________________________
7. _______________________________________
8. _______________________________________
9. ADK Tube Condenser Commemorative Edition microphone
10. ADK Tube Condenser Commemorative Edition microphone power box (supplies both power and phantom power)
Software...
11. Top-end operating system = Comes with Mac Mini
12. Logic Pro X music program = £139.99
Existing configuration:
ViewSonic HDMI 1080p Full HD LED monitor goes into PowerMac G4 (PowerPC processor) computer
PCI-424 soundcard within computer (works in conjunction with MOTU 2408 mk3 unit)
MOTU 2408 mk3 used as my audio interface for sound in and sound out. This means that the sound comes out of computer via the MOTU 2408 and out of my Quested monitors (they are active so self-powered) which are attached to the MOTU's outputs.
When I record vocals I sing into my ADK microphone (this microphone sources its own power from its own box which also feeds it Phantom Power) which is connected by a mic to jack cable to the Focusrite compressor which is connected by jack to jack cable to the MOTU 2408 which then goes into my computer via a firewire cable.
When I play keyboards or use my keyboard as a midi controller it connects to my computer via the MOTU micro lite (midi-usb interface).
I don't currently have a keyboard. I used to use my basic Yamaha PSR-540 keyboard as a midi controller but as it's not weighted and faulty I needed to get a new one. We got a new one via Thomann which was the M-Audio Pro Keys 88 keyboard but this quickly became faulty. We returned it and have since been considering other weighted keyboards. I am simply wanting a keyboard with Aftertouch, either 76 or 88 keys, weighted keys and very importantly, hammer action where the action is fast. I don't care for other controllers on the keyboard, on-board sounds, iPad compatibility or whatever.
My Questions:
Q1) Can you recommend any keyboards meeting my specifications?
Q2) I can't imagine any of the Blue or other USB mics competing with my ADK and I'm quite happy with it. For vocals and when I've wanted to play the keyboard in as audio (not as a midi controller) I've used the Focusrite compressor to boost the sound. I'm not using many functions/presets on the compressor as I know it's best to record the sound of vocals mostly raw, is this correct, and if so is it worth me continuing to use this compressor or sell it?
Q3) Do I need to have the MOTU micro lite (midi to usb) unit? Don't most keyboards these days connect direct usb to usb on the computer?
Q4) I'm happy and used to the sound out from my Quested monitors. I'm happy and used to the sound in using my ADK microphone. What do I need for these to work best with the Mac Mini? Is my MOTU 2408 good for this, or is another MOTU product needed, or another product altogether?
Q5) Depending on (Q4) do I need a soundcard installed in the Mac Mini as I read on a forum that these days the audio interface acts like the soundcard?
Q6) I have such a bad connection to the internet it's like I have Dial-up!!! I use Airport Wireless which is connected to a router downstairs, which is 02 Broadband. Internet's not an issue downstairs on my girlfriend's intel PC which also uses a wireless connection but not Airport. Is this a problem because of my Airport, or do I need to get a router for upstairs, or should I connect it directy to the router downstairs by ethernet cable?
Many thanks!

Is there a reason you don't want to use your current Tascam?

Apple TV mirroring issues even with Mac mini,airport extreme bought at the end of last year,and an iPad 2

Apple TV mirroring issues even with Mac mini,airport extreme bought at the end of last year,and an iPad 2

I have the same issue with ATV3 and iPhone 4S. Everything works properly, no buffering issues when watching netflix, vimeo, youtube BUT when I try mirroring even a small 15sec iPhone movie it stutters and buffers and results to a choppy playback..same with larger mp4 files such as 1-1.5GB, buffers forever and never plays, I just re-encoded the same movie to 700MB and plays perfectly..
Why Apple, why?..so close..I can accept the bigger movie files issue, but not being able to playback properly an iPhone movie is funny..I recorded a movie with lower bitrate through Filmic Pro (Economy mode, up to 16Mbps)
and plays properly.
Is there an upcoming software update going to solve the problem or is it hardware related and therefore not fixable.
Please don't reply with a network related answer, by 2012 we know how to set up our networks and everything else runs flawlessly.
I'll apreciate a fast answer, we love Apple, but if it can't play an iphone movie (or a high quality movie from iTunes) it's just not up to my standards.
Thanks again.

IPad Mini Won't Sync With Mac Mini (ios 8.1 OSX 10.6.8)

Problem : IPad Mini connects to iTunes OK, can be seen in iTunes and I can select which movies to sync to it etc. When I hit the "apply" button after making a change (ie deleting or adding a movie) the sync lasts just a second then the "sync" button remains greyed out, and I can't make them sync.

How do I sync new i phone with mac mini????

Open up iTunes, then go ahead and plug in your phone to the USB port on the back of the Mini using the USB cable that came with the phone.

Can I still use Appleworks 6.2.9 with Mac Mini 2012?

Can I still use Appleworks 6.2.9 with Mac Mini 2012?

Yes, MlchaelLAX, the KVM switch allow one to use one monitor, one keyboard, and one mouse between two computers. It has been so long that I'm not sure how to find the MODELS to the G4 and G5. Unless you mean what makes the Mac tick. The G5 is a dual 2GHz PowerPC, with 2 GB DDR SDRAM. The G4 is a bit slower, will look tomorrow.
I want/need a newer Mac model because unlike the days before OS X, all software was included as the newer OS were added, not so today. I'm still using Tiger because I still use a couple programs from the old days. When I eventually purchase a new model, I will have to buy all new software. That's find if one has plenty of money and wants to learn everything from scratch, but I'm hanging on as long as I can.
I tried TenFourFox, but it didn't allow video, of course since I tried Michael's suggestion, the video might not be an issue. So far, every thing works the way it should.
I have a lot of faith in Mac users, their loyalties to Apple is what kept Apple floating when many thought it would sink. These folks are survivors; I only wish the apple people on the top appreciated that loyalty today, but I guess things are too good.
Thanks to all for you kindness. Tomorrow I will show my husband how to remove his yellow threat on his G4. If anyone can answer any other questions, please know I will keep viewing this post.
