Brand new iMac, no internet

I got my new 2012 iMac 27" yesterday, and from the very start (the initial WiFi setup), it hasn't been able to get any internet. My other Macs and iDevices are fine with the same wireless router, and I've tried the new iMac with a second wireless router, and it's still not working. It connects to the wireless networks, but cannot send or receive data. I've tried Network Diagnostics several times with no luck. Any suggestions? Thanks for the help.

I would try checking the routers setup if it's set to use MAC address filtering (MAC is not releated to Mac as in the computer it just happen to be the same term)
if it does then you need to
1. add the MAC address of your wifi card on the imac to the list of allowed devices
or
2. disable MAC address filtering
if that didn't pay off then I would just to be sure
go to the router makers site to check if there were a newer firmware for the router
they fix bugs often and put out better working firmware
if that didn't pay off then I would try to brign the imac to a friend or family who have wifi too and test if it works there to see if the imacs wifi card was defect as in the antenna inside could have broken or something

Brand new IMac can't connect to Internet while using Vista Ultimate

The subject is pretty much it, but basically. We just bought a brand new IMac and I happened to have an old copy of Windows Vista Ultimate lying around and wanted to partition some hard drive space for gaming. During the installation a message popped up that said Lion only supports Windows 7. I went through with the installation and after Windows started I loaded in my old Snow Leopard CD. I installed the drivers and went through the set up. Everything seemed fine, but I am unable to connect to the Internet. I plugged my desktop in via Ethernet to my router but still no Internet. In my device manager there are many devices, including network controller, that have yellow exclamations next to them but I don't know how to update them or where to get the drivers. Any help would be greatly appreciated, and I would be happy to take any steps to relay more information. Thank you!

New motherboard. So unless you can find, and want to mess around, which is why the pdf guide and all the faqs tell you what and how to install, and that only 7 is supported.
Vista SP1 is no longer supported even by MS.
You have Sandy Bridge based system with Thunderbolt, hence it needed new device drivers.
Windows 7 64-bit SP1 Home Premium System Builder is $95

I have a brand new iMac (late 2012) that keeps losing its internet connection

I have a brand new iMac (late 2012) that keeps losing its internet connection - like every five minutes. I have had it for three weeks. During the first two weeks, it worked flawlessly. However, just as the refund period ended - it became desktop dead weight. Suggestions?

did u ever get a solution to this? I have the same 2012 mines 27". It drops after sleep sometimes and can't find anything. Wifi. Connection to the Internet. I pull up network assistant it just gives me blank stares and restart everything. It doesn't even see the time machines and they are still there. I have it right now in full error and my iphones allowing me to see everything as connected and I'm posting here in the forum while my iMac cannot. Doesn't happen all the time. Not sure why it happens or what's goinng on with It. Works great and then sudden wifi failure to recognize.

USB Dongle internet - brand new imac

When I try to use my usb internet dongle on my brand new imac it says I need java runtime which I can't just download beause it won't access the iternet. When I try to install it from a download on another computer it doesn't work. Can someone please direct me to te correct java runtime link or tell me if there is another way Ic an get it to use my usb dongle to access the internet.
It is an optus dongle. Thanks!

If you're iMac is new it has wireless (Wi-Fi) connectiivy built in.
You could try gping to system preferences, network and then trying to see if you're Wi_fi is turned off.
You should not need to use a USB dongle unless the dongle is a 3G dongle for connecting to a phone provider e.g. Orange, O2, Vodaphone etc.... if it is then I suggest you look a the providers website to see if they have a help page for getting the dongle working with an iMac.

How do I uninstall Mavericks and recover Lion? I have a brand new iMac and web pages stall or freeze since I installed Mavericks. I can't get it to download software for my printer when I connect it.

I have a brand new iMac. It was working fine until I downloaded Mavericks. Now I have web pages that freeze while trying to load. The blue in the address bar stalls and freezes. If I try to load from page 1 to a later page, or reverse that, I also have the same problem. I tried to connect my printer for the first time, and again, the blue progress bar froze. Then I got the yellow triangle telling me there was a connection problem. My internet connection is via an Air Card as that is my only option where I live. I packed up the whole new iMac and took it to my Air Card provider, where they also have very fast Wifi, and they had the same problem with Wifi. I use my Air Card with my MacBook and it works JUST GREAT! I really want to return to Lion. HELP.

The only way to retutn to Lion is to format your drive (erase, lose all) and either:
1. clone back the clone copy i hoep you have, or
2. first backup your files, then format and install Lion again
But really, mavericks works great. You have a problem. Find out why. First, what unusual software do oyu have installed that may be conflicting with it? Virus, system modifiers, etc? Second what OLD software do you have that might be the problem. finally, you might need to do a re-install if something errored during install.

Vmware fusion 5.0.2 cannot connect to network on my brand new iMac '27 late 2012

Dear friends,
I have tried to install Windows 8 (x64bit) Pro., Windows XP, and CentOS 6.0 using vmware fusion 5.0.2 over my brand new iMac '27 late 2012. However, neither one can connect to the Internet. There was no problem with the same installation on my iMac 2011.
The network board recognized by Windows 8 is Intel(R) 82574L Gigabit Network Connection.
In the folder of vmware fusion's setting files on Mac OS, I found a file called Windows 8 x64.vmx, and
there is a line as follows.
ethernet0.virtualDev ="e1000e"
Any friend has the same problem or can give me some hints?
Thanks a lot!

Brand New IMAC 27 overheats

Greetings to all from Chicago!
Just purchased a brand new IMAC (27 inch, 2.93GHZ QUAD-CORE INTELCORE I7, 8GB 1333MHZ DDR3 SDRAM - 2X4GB, ATI RADEON HD 5750 1GB GDDR5).
Previously had 24 Inch MAC (plastic on the back which is the point of my comparison. It still stand right next to the new one so I can compare.
The new Machine gets so hot that you can burn your hand. I am only running Logic Pro and Internet (same as on the old Machine). Measured via ISTAT PRO, the machine boots at at 25-28 Celsius (CPU temperature), then quickly warms up to 45-50 Celsius. It maxes out at 65-70 Celsius and stays there, NO MATTER which programs are ran. At that point, you can't even touch the top of the computer.
By contrast, my old IMAC 24 inch, stays cool, noiseless and never goes beyond 40-45 Celsius, when the same apps (Logic + intenet) run.
What should I do? Are all new IMACS like this? Is this because of the aluminum back? Shall I return it and wait for next year's model? Exchange? Repair? ( I have Apple Care). Here is how Apple advertised the new IMACS:
Cool, quiet components
"The widescreen iMac display allows more room to separate the two hottest components, the CPU and the GPU. This keeps things cool inside the iMac enclosure. Apple engineers also implemented an intelligent control system that monitors temperatures and delivers just the right amount of airflow to critical components. And the three fans inside iMac have been tuned to be ultraquiet. The result of all this tinkering with heat and sound? A system that operates at 18 decibels when idle — so quiet, you hardly know it’s on.*
Well, the reality is that it is a lot nosier and heats up a lot more than the predecessor, unless I have a defected unit.
Thanks in advance for all the input and recommendations
Cheers,

the components of the imac ARE cool & quiet, compared to other components. but don't make the mistake to think this means the imac is cool: it's an all-in-one-design, which just means it will get pretty hot, that's only natural. still, compared to normal computer components, the imac hardware is pretty cool, but that doesn't mean the case has to be cool. mine can get pretty hot too. I don't burn my hands, but it's painful to keep the hand on it.
as for the temperatures: 40-50 degrees celsius are normal for the CPU temp, everything above seems unnormal to me when your computer is idleling. what you didn't mention was your air temperature. are you dealing with hot weather currently?
anyway, also make sure in activity monitor no process is running wild and uses CPU. remember that the i7 has 8 cores, so 12% CPU usage actually means that one core runs at full speed!
besides that, if you have normal weather and no process runs wild and your CPU temp still goes over 50 degrees, I would call apple and they will likely exchange your imac

Brand new iMac: super slow web browsing

Brand new iMac is super slow while browsing the web.
We have cable internet, and the iMac is connected via ethernet cable to an Airport Extreme router. We have a Windows machine connected to the same router.
The Windows machine loads web pages extremely quickly, the iMac takes 20 seconds to a minute to load anything.
Clearly there is a settings problem on the iMac. No idea what.
It isn't the router.
It isn't the broadband connection.
It isn't the DNS server.
Please help!

I'm not sure if you understood my original post, however, I will re-iterate it here.
I have several machines connected to the same network.
MacBook Pro
Windows machine
iMac.
Only the iMac exhibits any problems.
Clearly, the ISP is not the issue. The iMac is connected via Ethernet to the same router as the PC.
Clearly the Mac is the problem.
Changing DNS server has no effect.

Brand new iMac kills home network

I have a home wi-fi network with a BT Voyager 2100 router and several PCs and laptops. All works fine. So today - I power up my brand new iMac and the home network stops. IE and Firefox on the PCs give "unable to find xxxx" error messages. I have tried the iMac with both wireless and ethernet connections to my router - same result. Safari on the iMac simply does nothing, blank screen. To get my internet back I have to power off the iMac and then re-start the router several times. Eventually all is well again. How do I get my iMac to work with a BT Voyager 2100 router?

update to my post - an old iMac G4 works just fine. So I guess that basic connectivity between iMac technology and my router is OK... so why does a brand new iMac give problems ?

No https on brand new iMac

Brand new iMac and I can't access https sites. I'm using the default administrator account so no parental controls are configured. The only thing I've done so far is connected to the internet, changed some personal preferences (desktop picture, dock behavior), and downloaded some updates.
Also, for being brand new with nothing installed/running, it seems to be running slow. Safari responds slowly, launching items from the dock takes minutes not seconds.
Any ideas for either of these issues is appreciated.

Not sure if this is relevent to gaining access to https sites, but have you installed the latest Java update from Apple?
Java for OS X Lion Update 1
It's been a while since I set up my new Mac but I think it came without Java installed and I had to downloaded it. If your Mac is new and has never had Java installed you won't be offered the update. You should have an app in your Utilities folder called Java Preferences. If it's there, launch it and see if it tells you anything.

Can't install photoshop cs6 on brand new iMac - "Media db error: 18"

At my company we recently hired a web designer – given his insistence on using the Adobe software, we decided to give Photoshop a try.
We downloaded a trial version and tried to install it on the brand new iMac (no previous installations of adobe stuff) we just bought for the new desigher, but... it's not even installing!
The installation process halts at around 2% and an error screen appears which gives generic instructions ("restart your computer and retry") and points to a log file where one can read "Media db error: 18".
Of course we tried restarting the computer, cleaning up ~/Library, re-downloading the installer... no good – we then downloaded and run an adobe cleanup utility... still no good.
Some people on the internet report they have the same problem... we found several questions on the matter, but no answer (besides "restart your computer" and other generic stuff that we tried and does not work).
We then called Adobe support (Italian support) and they told us they don't give support for trial versions, like we should sight unseen buy a (pricey!) software we can't even install! .
Can anyone here help?

Thanks for your help!
No, no beta or previous installations of any Adobe products – we are trying to install to a brand new iMac (just bought last week from the store): it has the latest version of everything (Os: Lion 10.7.4)
Is there any debug switch I can turn on on the installer to get further information on what's going wrong? ("media db error" is a somewhat laconic error message)

Mavericks on brand new iMac is very slow

I have a brand new iMac with the basic configuration and the latest version of Mavericks. I use iLife, iWork, Photoshop, Office, Dropbox and Mailplane as the main programs but it is very slow. I did not restore from a Time Machine backup and installed all programs and files separately but I often get the beachball and the computer is often very slow, it also takes a while to start up. Is there any way to see what is slowing everything down?
When I look at the activity monitor there are hundreds of processes but kernel_task always seems to be using 700mb+.
Any ideas would be hugely appreciated.

Hi, thanks for helping. Here are the results from your program.
In response to the other poster's question the beachball happens with iMOvie, iPhoto, Mailplane and photoshop.

Why does it take a really, really, really long time to download updates on my brand new iMac?

Brand new iMac.

It depends on our internet connection...

If at some point you need to repair the startup disk, or reinstall OS X, Apple recommends a broadband high speed internet connection for accessing About OS X Recovery
Macs no longer come with install discs so it's important to have a high speed connection to access OS X Recovery.

HT201250 I use Time Machine to back up my entire computer with my external hard drive. I am getting a brand new iMac this month and was wondering what is the process of using this back up to restore my new computer exactly how my old computer was?

I use Time Machine to back up my entire computer with my external hard drive. I am getting a brand new iMac this month and was wondering what is the process of using this back up to restore my new computer exactly how my old computer was? I want to make sure I will still have various important files on my new computer, like my songs in iTunes, my photos in iPhoto, etc, etc. Thanks so much in advance!

Welcome to the Apple Support Communities
When you turn on the new iMac for the first time, Setup Assistant will ask you to restore a backup, so connect the external disk and follow steps to restore all your files to your new iMac. Your new Mac will have the same settings and programs as your old computer.
In other cases, I would recommend to restore the whole backup without using Migration Assistant or Setup Assistant, but a Late 2012 iMac uses a special OS X build, so the OS X version that you're using on your old Mac won't work on the new one.

New iMac wireless internet crashes repeatedly -- why?

Just set up the following wireless LAN: Netgear WGT624v3 wireless router as access point between a broadband cable modem, a new 27" iMac, a PowerBook G4, and a Canon wireless printer. Everything works great except for one thing: whenever I'm trying to use the internet on the new iMac, my internet connection crashes and I have to manually reset the modem and router. This happens when downloading a file even as small as 2 Mb. As you can imagine, this has become incredibly irritating, as none of us can get anything done on our new computer without me having to come over and flip a switch on the power strip to repeatedly reset the internet connection.
The Netgear router is about as old as the PowerBook (3+ years)--I see it's listed "EOL" (end-of-life) on the Netgear website, and I'm wondering if it may not be powerful enough to handle the new iMac? That's the only thing I can think of, since using the internet with the PowerBook causes no problems at all. I don't understand the subtleties of Airport v. Airport Extreme, 802.11b, g, n or whatever, to figure this out on my own.
Anyone had a similar problem and/or can confirm that the router is the culprit before I needlessly spend money on a new one?

Some things you can try, if you haven't already:
-Make sure you don't have any cordless phone base stations operating near your router.
-Are any other electrical appliances (like microwave ovens or fluorescent bulbs) operating when your wireless connection fails?
-Power down the router and the iMac, then restart each.
-Change the channel your router uses to broadcast its signal. You should be able to do this from the web browser interface most routers support.
-Check Netgear's support website for firmware updates. Some routers can be commanded to check this from the web browser interface.
