Mac Mini 2011 wont stay online

Mac Mini 2011 wont stay online via ethernet nor wireless, all other apple products are connecting fine

Take each of the following steps that you haven't already tried, until the problem is resolved.
Step 1
Restart the router. Many problems are solved that way.
Step 2
Change the name of the wireless network, if applicable, to eliminate any characters other than letters and digits. You do that on your router via its web page, if it's not an Apple device, or via AirPort Utility, if it is an Apple device.
Step 3
Run the Network Diagnostics assistant.
Step 4
Back up all data.
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Enter the name of your wireless network in the search box. You should have one or more "AirPort network password" items with that name. Make a note of the name and password, then delete all the items. Quit Keychain Access. Turn Wi-Fi off and then back on. Reconnect to the network.
Step 5
You may need to change other settings on the router. See the guidelines linked below:
Recommended settings for Wi-Fi routers and access points
Potential sources of interference
Step 6
Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
Step 7
Reset the System Management Controller (SMC).

Unable to Troubleshoot Power Issues on Mac mini 2011

I have been having odd and intermittent power issues with my Mac mini 2011 and could really use some help before I resign myself to taking it into an Apple Store. It's under warranty, but I now live in another country so I hope I don't need to ship it should it come down to that.
However, I have searched this topic a lot, and not only have I tried troubleshooting it, I haven't seen any power issues with other owners of this model. That leads me to think that the power supply itself is probably OK.
First of all, I live in China and the building I live in seems to have a questionable power supply. The air conditioner for example simply would not work and the repairman spent two hours messing around with wires inside the outlet and in the breakers. That did the trick, so I wonder if I'm simply not getting enough juice?
Main symptoms:
- My monitor recognizes an analog signal but will not light up (black monitor). Unplugging and replugging adaptor doesn't do anything.
- Startup Keyboard Commands (e.g. Cmmd-R) may work, but I can't tell because the monitor won't light up. Letting the computer boot up though I can hear keyboard volume keys and such making the standard sounds. I can usually restart using the keyboard too.
- My 2T external HD more often than not dismounts as well.
- I can't hear any computer activity after the chime (hard drive, etc.).
- Since I can hear the chime and there is audio feedback through the keyboard, I think that eliminates hardware problems such as logic board failure or bad RAM.
- I can't boot even if I unplug all USB peripherals.
- Holding down the power button (I have it set to make the computer sleep as well as shut down) often won't shut down the computer, but it seems to stay in sleep no matter how long I hold it. Unplugging the computer finally shuts it down, obviously.
- Unplugging and waiting 5 minutes or so and powering up again doesn't seem to make any difference, nor does switching sockets, plugging directly into the wall, etc.
Problems began about two weeks ago, got better, and then worse again. Now I'm just keeping the computer and monitor on (never sleep 24/7).
Miraculously, after much frustration and countless restarts, suddenly the screen will turn on to reveal a fully booted system that was running all along in the background. No startup screen- the monitor just magically comes on again. Often I find that my external has unmounted, but it's no big deal to get to remount. At this stage, the Mac is still very quiet and for a while the system is sluggish, though it hops back into action in 5 or 10 minutes.
At first I thought it was just my monitor, and though that's possible I suppose, it seems I'm just not getting enough juice. Once the monitor is on though, everything is fine: I can power it off and on with no problems. But I can't just leave my computer on forever though.
Any help appreciated.

Well, with the other monitor (which did not work with the mini either but worked fine on a laptop), I was able to narrow the trouble spot down to either a faulty Mini Display to VGA adaptor or a damaged port. I could determine that all the other ports (incld. the USB drive, programs, internet, etc., were all working fine behind the big black GUI all through sound feedback, so I seriously doubted it could be a supply problem or a residential electric problem.
I took my mini and adaptor to a "Mac Shop" (reseller) here in China, and found it quite professional, just like a Mac Store. They tested my machine, and although they didn't have VGA monitors, they said I could return the new $30 USD adaptor if it didn't work. But as I'm writing this on the monitor now, the new adaptor did the trick.
The long and short of all this is that I've read a lot about display problems with the mini and I suspect that most of these problems are adaptor related. I myself tried to save some bucks by buying a third party plug and lived and learned. I hope the Apple adaptor works like a champ, and if it doesn't, I'll know the first thing to eliiminate next time.

Mac Mini 2011 screen blacks out during heavy screen activity

I have a Mac Mini 2011 i5 2.3Ghz with Intel HD video. It's connected to a 30" LCD 2560x1600 (Dell WFP3008) via mini-DP to DP cable and a 22" LCD 1920x1080 (Samsung LCD TV) via HDMI to HDMI cable.
For the first few weeks I had it connected to the 30" only and it was fine. Then I hooked up the Samsung as a second display and the problems started.
The problem is that the Dell blacks out briefly, then comes back. It is not "drawing" the screen black, the signal to the Dell gets disrupted momentarily so the monitor has no signal so it goes black. Then it resyncs with the signal and the display is back. This only happens to the Dell, during the disruption, the Samsung image stays put. I know it is a signal disruption because the Dell shows a displayport icon showing that it has just resynced to that input.
The problem happens more frequently when more things are going on; like if I have a window or multiple windows playing video, then the disruption happens more. If I disconnect the Samsung, it happens less. It could even happen if a web browser window taking up a large portion of the 30" screen does a full page update, it will disrupt. If I am running Adobe Lightroom, it seems to happen more also.
When it happens it seems like messages like this appear in the console, although i can't say they are directly correlated:
6/1/12 8:28:46.000 PM kernel: IOSurface: buffer allocation size is zero
I'm thinking perhaps the mini is running low on memory since the 2560x1600 is pretty high res and then add the 1080p screen and stuff being updated, perhaps it runs out of memory and disrupts the signal while it garbage collects? Pure speculation.
Has anybody else seen this and have any clues on how to resolve it? Thanks.

I should clarify that when I say perhaps the mini is running low on memory, I mean low on shared video memory, since the computer has 16GB installed. I'm not sure how to view or test shared video memory allocation.

Opinions about if Mac Mini 2011 works ok with VGA monitors

Hi Community,
I have a old HP PC, I want to buy my first Mac Mini and used the keyboard, mouse and VGA monitor (Mod. HP Pavillion mx50) that I have.
Before I purchase the new Mac Mini 2011 and Mini DisplayPort to VGA Adapter, I would like to know if it works ok with my old components, specially with the VGA monitor? I've read on this Community there some persons have monitors problems.
I don't want spend my money and then have problems with the Mac Mini.
Thanks in advance,

MiniDisplayPort-VGA adapters. Available in the online store, at Apple stores, or at BestBuy/MicroCenter/Fry's. Plugs into the Thunderbolt port.
Usually works without issue. But then I use monitors made by LG and Samsung. Others use lesser known brands or models know to have quirks and encounter issues.
Some things to watch for:
Soem adapters have too much plastic coveing the "connection plate", and the cable cannot seat fully. If you just look at one that has too much plastic, you will know what I am talking about.
VGA signals from Macmini are not strong enough to get through mutliple adpaters. If you want a VGA signal, buy 1 VGA adapter. If you want a DVI signal, buy only 1 DVI adapter. Do not get a DVI adaper, than add a mid-line converted to change the DVI adapter to a VGA port.
If you plan to run Windows under BootCamp, the Windows driver for the Tunderbolt port does NOT output snalog (VGA), just digital (DVI, HDMI). So if you plan to use VGA to display Windows output, run Windws under "VM software" (Parallels or VM Fusion) so that OSX can make the VGA signal for you.

Mac Mini 2011 and EFI

Hi, does anyone know if the New Mac Mini 2011 being sent out if purchased from the online store has the EFI firmware ready installed?
I guess only someone who has received one in the past week would know
I am about to buy one to update from early 2009 model and wonder if I should hold back for a bit.
Thanks

Thanks for the information, just ordered, so I know what to check for when it arrives in the next week or so.

Mac Mini (2011) can't boot, no screen display.

Hi, my mac mini (2011) finally won't startup today.
It was since two weeks ago, the mini goes freeze very frequently, I discovered that the fan speed was always below 2000rpm, meantime, the CPU temp was around 80-90 degree, it is around 25 degree in the room, last Friday I installed a software named smcfancontrol, which can manually speed up the fan, and it seems better, and the computer runs faster, I think the CPU is running in full speed.
Today, I opened a video to watch, after about ten minutes, the computer goes freeze again, and of course I force powered it down by pressing the power button on the back, then the tragic came:
- when I try to boot up the machine, the front light turns on, then off with a "ka" sounds like the hard drive shutting down(force powering it down)
- after around two seconds, the light goes on again, and the fan smoothly goes to full speed, there is nothing shows up on screen, as well as no apple boot up sound.
- I tried to reset smc (power down, unplug power cable, wait 15 seconds, plug in power cable, wait 5 seconds, power on), no luck.
- I tried to reset pmu (at least internet says it's pmu, it seems apple website did not mention how to reset pmu on mac mini, power down, hold power button for five seconds, power on), no luck
- I also tried to unplug the memory, try with every single one to boot, no luck
- last Friday, when I can still boot up the computer, I thought there might too much dust, I removed the fan and cleaned it up, it looks a small piece of plastic on the fan plug were damaged, but the smcfancontrol app still can control its speed, therefore I think the fan is OK.
- during many retry, there was one time, the fan goes full speed at startup, with no front light off,(my current status is fan goes to full speed gently).
- the computer is connected with an AV amplifier, then output to a plasma TV, when the computer is powered off, the TV displays a background of amp, when I startup the computer, although no video output from computer, the TV goes to a "No Signal" status, I dont's think this is related to my problem.
the computer is out of warrentee, but bought only for less than two years... I really want it back to work, can someone help me? many thanks!
wish you all have a good day.

Hard to troubleshoot when you can't turn on the computer on any more. One option is to bring it to an Apple store to have them look at it. They will tell you what is wrong and how much it will cost to fix. I have never heard of them charging for a diagnostic and an estimate.
If your CPU was running hot all the time and your fan had small plastic pieaces, in my opinion, something got fried. The mini is so compact, that the excessive heat may have also over heated your hard drive causing thd "ka" sound.
If you decide to continue in to use a Mac Mini as a media server, may I would suggest using iStat to monitor it. I use iStat on my 2011 Mac Mini Media Server to monitor CPU usage, all sensors, and internet incoming and outcoming.

Hello, I am interested in buying this week of a mac mini 2011 with intel graphics HD3000 but I'm not sure it looks good with my Samsung SyncMaster933HD monitor. How would it look better with the hdmi-dvi connection or a built-in display adapter port-vga

Hello, I am interested in buying this week of a mac mini 2011 withintel graphics HD3000 but I'm not sure it looks good with my Samsung SyncMaster 933HD monitor. How would it look better.... with the hdmi-dvi connection built in, buying a HDMI 1.3 cable and HDMI-making or buying an adapter hdmi display port - vga and connected through the port thunderbolt
Thanks

I originally set up my mini with the included HDMI -> DVI adaptor to connect to a Sycmaster monitor. The graphics were very good.

When I connect my Mac Mini 2011 with Lion to a TV via HDMI and an earphone cable is plugged in, it´s not possible to choose sound out via hdmi, as opposed to connection via minidisplay port. Anybody knows how to fix this?

Was just on the phone with Apple about this.
The solution was as follows for me anyway...
Go to your Finder
Choose the Go Menu
Choose Computer
Choose your Macintosh Hard Drive
Choose your "Library" Folder
Choose the "Preferences" Folder
There should be a folder called "Audio"
Move that whole folder to the trash
Empty the Trash
Restart from the Apple Menu
When you are back up and running;
     Choose System Preferences from the Apple Menu
     Choose Sound
      In the output tab you should now be able to make the HDMI "Sticky"
      Enjoy your sound over HDMI and no more dirty knees or broken backs unplugging the desktop speakers!

How do I downgrade mountain lion back to my mac mini 2011 lion server

Hi,
Previously, my mac mini mid 2011 was installed with mac os lion server then I have purchase and upgrade to mountain lion via iTunes.
Somehow I decided to downgrade back to lion server due to use of my mac as server, unfortunately I have no idea how to downgrade with the following reasons:
1. I don't create any time machine backup before so can't use that option.
2. I have enable vault function so now the startup has hide the recovery HD icon
3. In the Recovery mode (command + R), I only see an option to download and reinstall a fresh Mountain Lion only.
4. I can't download and install Lion server from iTunes because this os was bundle with purchase of mac mini 2011 mid version.
Any comments and helps here are appreciated. Thanks.

Well, did you save a Carbon Copy Clone (http://www.bombich.com) of the Lion installation by chance? That would be the easiest to go back to and use / update. Outside of that, or having saved the original Lion installer, I know of no way to get the OS that you are after. For future referece, on a mac mini with two harddrives, I have always made a backup partition on the second drive using CCC, and schedule clone updates to that. You can't rely on TM, inmo, so something like CCC or SuperDuper is essential. Cheers,

Having problem installing Win7 using Bootcamp on Mac Mini 2011

I'm trying to install Win7 using bootcamp on my new Mac Mini 2011. I first partitionned the disc using Bootcamp assistant. Then during Win7 installation I select Partition 4 BOOTCAMP, format it to NTFS, then when I try to select the drive, it says that the drive is not compatible for the installation.
Is there anything I missed???
Thanks

I had a similar problem when I selected upgrade instead of complete install. I want to make sure your aware that you should click the complete option instead of upgrade when you reach that portion of the win7 install. Then you need to select part ion 4 like you have stated and format it to ntfs.
But it seems that you've already done all of that. My advice would be to go back to the Mac side, restore the partition using bootcamp and again partition it. You need at least 25gb of space for 64 bit. I would recommend using at least 40gb. Just trying to help. I apologize if I misunderstood your problems. But make sure you click on the opposite choice of upgrade, I did my mini last night lol but I can't remember the exact name of the option I think it's complete, then select part 4 and click format....

WiFi slow when running Windows 7 on Mac Mini (2011)

Hi,
I have just bought a Mac Mini (2011) and used Boot Camp for installing Windows 7 as well. However I am experiencing some problems with the WiFi when running Windows. The speed is less than 10% of what it should be. I have tried connecting a network cable and then everything is running fine. When booting into OS X Lion there are no problems with running WiFi. I have tried to rightclick on the network adapter and select update drivers but it says that the driver installed is up to date.
Any ideas?

Apparently it was a router issue. When I connected my old Cisco router as an extended access point both the Mac OS and Windows session connected as supposed to. I made a factory reset of the router provided by my ISP, configured it again and the problem apparently seemed to be solved.
However overnight the problem occured again - I swithed the router off and on again and was able to connect. I noticed in the DHCP log that when running Mac OS the computername "My-Mac-Mini" is sent to the router with the MAC address of the network card - when running Windows it is the machine name I entered during the Windows installation. Not sure if that is confusing the router from my ISP but after I changed the computername in Mac OS the connection seems stable.

On the mac mini 2011 how can I run windows 7 without the optical drive, On the mac mini 2011 how can I run windows 7 without the optical drive

On the mac mini 2011 how can I run windows 7pm bootcamp without an optical drive. I watch lots of football on sop cast and other such windows based programmes but can't work out how to do it.

Actually Windows can be installed and booted from an external drive if the drive is connected eSATA (external SATA), since the drive is treated as if it's an internal HDD. I used the same method previously to dual-boot from 2 different HDD instead of partitioning.
Most PC motherboards come with them as standard so it's pretty much plug and play but I don't recall seeing a recent Mac with eSATA connectivity though, so that might not be an option for you.
