MacBook Pro Retina says connected to ethernet, but will not connect

I have a MacBook Pro 13" Retina. It will not connect to my office's network no matter what I do. I've tried different cables, different ports, toggling wifi on and off, inspecting the ports to see if they will recognize other thunderbolt connections and they will. I was able to connect to a Thunderbolt monitor without any issues. It may be the adapter, but there are all kinds of funky-ness going on when I try to assess the network. The thunderbolt heading under System Information claims nothing is connected - even when communicating with the Thunderbolt display. The ethernet connection claims to be working, but will not connect to the internet. It also can't seem to find our router. I've tried to manually enter all the information in using the assistant, but it still can't find it. This is especially frustrating since this computer is under a year old. I can't take it to the Genius Bar because it is owned by my company and contains proprietary info. Any help would be greatly appreciated.

Hello NotAppleSavy,
Thanks for the question. After reviewing your post, it sounds like the computer wont connect to networks. I see you have used network diagnostic. I would recommend that you read this article, there are a lot of other things you can do in this article that may be able to help you resolve or isolate the issue.

IPhone 5 says it has 3G, but will not connect to the internet unless connected to wifi

iPhone will not connect to any apps connected to Internet or send IMessages. I can still call and text. I have tried resetting network settings, starting from factory settings, and a hard reset. Other info: I have straight talk. I recently updated my phone. Apps work when connected to internet.

Having 3G doesn't mean you can connect to the Internet.
You must have Cellular Data properly provision by your carrier.
Also check iPhone Settings > Mobile/Cellular > Mobile/Cellular Data: ON

HP Officejet Pro 8500A Plus Printer will connect to apps but will not connect to EPrint

OS MAC 10.6.8 Snow Leopard. I am using a wireless connection, no USB, and everything worked fine at one time. Recently, all remote printing, including Airprint stopped connecting. I am unable to access anything on the HP website via the printer except for the Apps. My network is working fine and I have done all the troubleshooting steps recommended throughout the Help system with the exception of returning the printer to factory defaults. Unfortunately, I removed the printer from my ePrint account and have now lost access to my printer e-mail/claiming code. Thus, I can do no troubleshooting via the HP website. I have tried using the original code the printer came with and the e-mail I changed the printer to after installing it and neither works. I have a bad feeling I will not be able to use the ePrint features any longer with this printer and with my warrantee expired, I will be thoroughly po'ed about this.

Hello lynnmilicevic,
First I want to reassure you by letting you know that the web services support has no expiration. Next I want to address the issue with ePrint. You will not have to take the printer completely back to factory settings, but you will have to disable and re-enable the printer's web services. You can remove the web services by going to the setup menu, select the web services setup, select restore factory defaults ( note, this only restores web services to the factory defaults, everything else, i.e. wireless, fax, ect., will still have the settings that you have created), and select yes. You will get a message saying that the web services have been reset. Now go back to the setup menu, select web services, and follow the prompts to re-enable web services. Once you have the web services enabled again, you will have to go the eprintcenter.com, log in, and add the printer to the account again. A very unfortionate part of this is that you will not be able to get the same custom e-mail for your printer. The original custom e-mail will be locked for about 6 months. If this does not help, let me know and I will see what can be done.

Mid-2009 MacBook Pro sees internal SATA hard drive, but will not boot from or format

I inherited a Mid-2009 MacBook Pro (15-inch, 2.53 GHz model) with a very strange issue.
It first presented itself as not being able to boot from the internal SATA hard drive that came with the computer. Nothing I tried could get it to boot, so I assumed the file system was corrupted beyond repair and booted from a CD to try to format the drive. Disk Utility on the CD would not format the drive, giving me strange error messages like "Unable to write to the last block of the device".
At this point I figured the drive itself must be toast, so I pulled it out and put another known-good SATA hard drive in, booted from CD, and attempted to format. Again, same error messages and an unsuccesful format.
So I had the bright idea of formatting one of the drives in an external enclosure and then putting it in the MBP to see if OS X would even install. No dice. Get a cryptic error message before installation even begins.
So I installed OS X on the drive in the external enclosure and put it in the MBP, and it attempts to boot, but never goes anywhere.
So to sum up, the symptoms I'm seeing:
MacBook Pro CAN see internal SATA hard drives.
MacBook Pro WILL NOT boot from any internal SATA hard drive and cannot format or install OS X to any internal SATA hard drive.
MacBook Pro WILL boot from any CD or external device and seems to work properly otherwise.
At this point I'm thinking it's one of two things: the hard drive ribbon cable or the SATA controller on the logic board.
Since the MacBook Pro seems to work completely fine other than this one issue, and will boot properly from both external devices and the CD (also a SATA device), I'm thinking and hoping that it's just the hard drive ribbon cable. From my searches online, I've heard that this batch of MacBook Pros is known to have issues with the hard drive ribbon cable, but it seems in most cases this manifests itself by the Mac not being able to see a drive at all.
I've done quite a bit of troubleshooting to get to this point, but right now I'm just looking for any feedback at all. Specifically I'd love to know a way I can easily test to see whether it's the logic board or the cable.

UPDATE: An interesting development!
I just tried a third known-good SATA hard drive, one which I believe supports SATA I only (but I'm not sure), and unlike the other drives that the Mac sees but cannot properly interact with, the Mac can't even see this one when I put it inside.
Frustrating as this may be, I believe I'm actually getting closer to a solution since my symptoms now appear to be closely aligned with people having SATA ribbon cable issues.
Onward!

Macbook will connect to wifi but will not connect to internet

Lately I've been experiencing an issue with my internet, my computer will connect to wifi, but the internet will not work. I have tried multiple wifi networks, and sometimes the internet works but it is slow, or sometimes it won't work at all. For whatever reason apple.com is the only one working at the moment.. how convienent.. I have rebooted my laptop, the router and my operating system is up to date. Please help!! I'm a college student and internet is crucial for one of my classes!

Wireless connection is there but will not connect

Hi I have a 2 year old Macbook and I have been using Windows XP SP2 via Boot Camp for a couple months now. The internet connection has been fine up until tonight. Nothing was changed, except now I cannot connect to the internet. The internet works on my OS X partition, but when I come onto Windows, it will not. When I see the available wireless networks, it comes up, with 5/5 bars, as if it were a great connection. When I click it to connect, it just keeps connecting, without even prompting me for my WEP password. I don't know what could have changed!
I have tried installing the drivers from the Leopard disc again, as well as downloading the Airport utility on it, however to no avail.
Any ideas out there?
Thanks a lot!

Same problems. Sp2 via bootcamp. Legit copies. My wireless was working fine, and then one day it just stopped receiving packets. Says it's connected and good but I is functionally uselesss when I try and load anything. Really need help with this, I feel like I've tried anythign except a reformat. I also spent a good while looking throguh these forums for an answer and nothing has worked so far. Thank you!!

My Macbook Pro suddenly, and for no apparent reason, will not connect to the internet?

About a week ago I went to go online and my computer said I had no internet connection. Around that same time I noticed that my background on my desk top was back to the factory set background it came with, but I did not change it. That is the only thing I noticed out of sorts. I asked the other members of my family if their computers had internet and they DO. So does my iPod. I knew it was not my internet service, but my computer.
There is a "!" on the internet signal icon (top right). When I click on it I get a message in the drop down menu that says "Alert: No Internet Connection...." When I click on that, I get "Network Diagnostics" pane asking me to select location. I choose 'automatic', 'continue', then 'Wi-Fi' and 'continue'. Then it asks me to select Wi-Fi network. I highlight my network then continue. At this point, the words on the left are Wi-Fi- with a green dot, Wi-Fi settings with a green dot, Network settings with a yellow dot, ISP with a green dot, and Interenet and Server both with red dots. Then it comes up * "Network Change Detected - your network configuration has changed. Click OK to proceed to the next step". When I click OK, it asks me for wireless security info. I choose WEP password and then put my password in, and check the box next to "remember password in keychain", then continue. Goes right back to the "Network Change Detected" message at the * above and all the dots to the left accept the Wi-Fi one are now RED. I just keep going in circles from there, continually coming back to this message no matter what I do! I have no idea what happened or what to do?!
Does anyone have any ideas? Please help! I am a student and don't have any money to take it to a professional. I am the only one in my house that has a Mac (everyone else has PC's) so no one can really help me troubleshoot. I'm not a techy at all, but can follow directions if anyone can give me specific steps to try. Thank you so much in advance!!!!!!!!!!!!!!!!!!

Iphone 5c is connected to Wifi but will not connect to internet

Have had my Iphone for a year now and have never had this issue before. The device shows I am connected to the wifi but tells me it cannot connect
to the internet. Any ideas?

I know having wifi connection is important to your data usage amlaco. I'm sorry you're not able to use the internet . Have you tried to disable your wifi connection and renable it? Are you connected to your home wifi? Have you contacted your internet provider that is connected to your wifi?

Isaaura - what printer model do you use?
While opening Safari click the Bookmarks icon and select Bonjour.. can you see the printer listed there?
(If Bonjour is not listed click Safari > Preferences > Bookmarks and check Bonjour within the Collections section)
Can you access the printer by typing its IP from Safari?
If the printer not available only thoguh Bonjour but an be reached by its IP, what router brand and model are you using?
Templeton Peck - correct me if I'm wrong, the different OS X forums have a dedicated forum for printing and scanning.. as Apple no longer produce printers about the last 2 decades I would assume those forums meant to deal with other manufactures over OS X..
john galt - Am I spelling OS X correctly?

downloaded acrobat reader 11 onto my Mac Book Pro, it can open the file but will not print. Get a message that says PDF cannot be printed, however, I forwarded it to someone else and they could print it, no problem. I called HP and spent an 1hour with them and then called Apple support and worked with them for 3 hours. No one can figure it out. Is there something wrong with this version? the pdf was created in 2004. Do I have to pay to get Acrobat?

Let me give you a slightly different perspective than everyone else here. You are using an unsecured wireless network, which means that all your network traffic is easily available for viewing by anyone else using that network. That's bad. Very bad, for you, unless you absolutely trust everyone who lives within range of this network. So stop doing it.
As to the Mac not connecting, wireless networking is simply too complex for any reasonable answer without more information. There are many possible error points, and as often as not it's the Mac that can connect and the Windows PC that cannot. Since you can't give us any information about the configuration of the neighbor's network, and can't make any changes to it, we can't do much to help you troubleshoot it.

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet".How can I change ip address?

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet". If this is the root of the problem,how can I change ip address?
Ipad will connect no problem to other networks.

First thing you need I think is to get your iMac connected to the Internet.
Shut down your iMac and you iPad. Then power off your router. Wait 30 seconds and power up the router.
After the router indicates that it is connected to the Internet then start up your iMac and see if it connects. If the iMac connects to the Internet then your iPad should too.
If this power up sequence doesn't work you'll have to dig into the router setup to make sure it is working properly.

I've transferred my itunes library from PC to Macbook pro running latest itunes and now it will not recognize my iPods (nano 4 and 5th Gen an Ipod touch). All music is there and playable but will not recognize any devices. Help please

The ipod is not a backup/storage device.
You need to copy everything from your old computer to your new one.
The Apple store will do this for you, you can call apple support and they will help you, you can use google.
