Macbook pro wont connect to internet using cable, but connects using wifi fine
My macbook pro wont connect to the internet using a cable, but connects using wifi fine. I use wifi at home but sometimes need to use my laptop at work and connect using a cable but it says i'm not connected to the internet?
Can you open a terminal and invoke the following commands:
ping -c 10 localhost
and
ping -c 10 google.com
You should normally get something like:

Is there are a way to use my imac as a display for my macbook pro? I have a thunderbolt cable but it doesnt seem to do anything
Hello eassic,
Thanks for the question, and welcome to Apple Support Communities.
It sounds like Target Display Mode may be what you are looking for:
Target Display Mode lets you use a Mac as the external display for another “primary” Mac. In some cases, you can also play the sound from your primary Mac on the speakers of the external Mac. For example, a MacBook Pro could use a 27-inch iMac as the display and play its audio on the iMac as well.
OS X Mountain Lion: Use another Mac as a display
http://support.apple.com/kb/PH11302
Use an iMac with Thunderbolt as a display
If you have an iMac with Thunderbolt, any other Mac with Thunderbolt can use it as a display. The iMac will play both the video and audio from the other Mac.
1. Connect the Thunderbolt cable to the Thunderbolt ports on each computer.
2. Make sure both Mac computers are turned on and awake.
3. Press Command (⌘)-F2 on the keyboard of the external display Mac.
4. If you want the external display Mac to play audio as well as video from the primary Mac, choose Apple menu > System Preferences, click Sound, and then click Output. Select the external display Mac from the list of devices.
Thanks,

Can't connect to internet with itunes but am using Internet on machine
itunes is telling me that i have to check my internet connectivity however im on the internet just fine. Please help. i tried to upgrade itunes, uninstall itunes, and still nothing.
Hello okiska. Welcome to the Apple Discussions!
under system preferences is says "airport is connected to the network", and Airport utility says "your apple wireless device does not have a valid IP address".
What these are telling you is that your MacBook Pro is connecting to the AirPort Extreme Base Station (AEBS), but the AEBS is not "communicating" with the modem.
I suggest a complete power recycle of your network components to get things working again.
Try the following, in order, checking for Internet access after each step, until resolved:
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
Modem/Router Power Recycling - Quick
o Power-off the modem, AEBS, & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the modem, AEBS, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the modem; Wait at least 15 minutes.
o Power-on the AEBS; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset." -
My 4month old Macbook pro wont turn on unless plugged in, but remains on after unplugged.
I got a brand new macbook pro 4months old. What happens is it does not turn un unless it is plugged in when I unplug it though it is fine and will run till it dies, BUT if I were to close it and put it to sleep it will not turn back on. I would have to plug it back in and turn it on then I can unplug it and it will be fine till it falls back asleep.
Once I do turn it back on, a pop up says that I need to re adjust the clock and another trying to search for the internet, even if I was already connected with is 5 min ago. Even apps like tweetdeck and facbook would reset and I would have to enter all my information again, where as before it would just remain there.
I have NO idea why it is like this and I am not really familiar with a Mac and its OS but any information would be greatly appreciate!
Thanks!
YoshiBring it to an Apple store or AASP. You are under warranty.

Does anyone know how to set up a macbook pro so that other computers can join me and use my internet connection?
Have you set up any security on the Mac Connection Sharing?
Sorry but I don't use that so I'm not familiar with the settings.
But if you haven't setup and security the iPhone might not mind but I know most Windows computers do not like to connect to Open WiFi. and make sure it is WPA or WPA2.
Then again it may be a setting in the connection sharing like some type of MAC filtering or it may simply be that Mac OS X connection sharing only allows one connection at a time. Try disconnecting your phone and then connect the PC.
As to Linc's response about Windows.
Windows basically does care about connecting to open, unsecured, WiFi. But it will normally pop up a windows asking "Are myou sure you want to connect to this open network". And a simple click on yes will get you connected and an IP address.
So this is clearly a Mac OS X problem. -
I use two MacBook pro, two iPads and two iPhones. Upon connection and attempt to synchronize photos I receive a message that my authorization limit is exceeded. I read that iOS devices do not count against the authorization limit. One iPhone and one iPad show in the authorization list. iTunes wants to delete my purchased programs and books from the iPad to continue synchronization. What can I do?
Ok, now I do wish I could edit....
I forgot to APPLY the network settings for the USB cable to work. Connected thru USB I can tether.
So, I kept playing, and playing some more...
I had previously unpaired everything, and gone as far as removing network devices HOWEVER...
I didn't remove the Ethernet, Firewire or Airport Network devices.
Now, I have done so. I REMOVED EVERYTHING
No pairing, no network devices.
Bluetooth was already turned off, and I rebooted.
I turned off tethering and rebooted the iphone.
I turned on bluetooth (on the MBP), I turned on tethering. I browsed for the iphone. It said I was already paired???? Ok, repair AGAIN, and THE IPHONE SHOWED MY BLUETOOTH TETHERING BLUE BAR at the top of the screen!
I opened a web page, no go... d4mn, I was close...
Opened network preferences and the created a new bluetooth PAN and voila! Internet back on the MBP. I am about to reinstall the ethernet and airport (I can live without firewire for now) and see what happens.
Basically, the link I posted two posts ago, I had already done that, but I NEEDED to remove ethernet, firewire and airport as well...
So MAYBE it's fixed, we'll see for how long. I'm not going to mark this as answered for now, because basically, it has failed for no reason, and I want to know why...
Hopefully someone can come up with something, but having to delete and reinstall all pairings and network devices (to me) is not really a solution, it's a workaround (at best). -
Every time my MacBook Pro is put to sleep, it will not connect to the internet upon reopening unless I perform diagnostic assistant.
Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved. Make sure the box marked
Remember networks this computer has joined
is checked.
2. Follow the instructions in this support article under the heading
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
3. Reset the PRAM.
4. 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.
5. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
6. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
7. Repair permissions on the startup volume.
8. Turn off Bluetooth and test.
9. Reset the System Management Controller.
10. Reinstall OS X. -
Having problems connecting a late 2011 Macbook Pro 2.2ghz i7 to a Sony KDL-32L5000 using a display miniport to DVI adapter (DVI to VGA cord). The TV is not detecting the macbook. Anyone have this problem?
You really have to mess with the resoluton, espescially the refresh rate, as it varies from projector to projector, monitor to monitor. Even within the same brand! Because so many manufacturers are trying so many different things to become the next cool kid on the block, and the way the formats are being configured that's now part of the game.
That's why so many professionally produced corporate shows hire a dedicated projectionist for the video presentations. Too many bugs in the honey.
Refresh & sesolution are the first things to look at.
Just so you know that colors in PowerPoint PC, and PowerPoint Mac, don't exactly match... go figure.
I forgot to mention another thing, sometimes it's the projector that needs to be tweaked. -
Macbook Pro (Lion) won't recognize Ethernet cable
Hi
I'm using a Macbook Pro (15 inch, Early 2011, Built-in OS X Lion 10.7.5)
Normally I connect over Wi-Fi and I have no problem. I used to connect via Ethernet (Cat6 cable) sometimes when I was at work and I had no problem back then ( I didn't have to change any settings).
Recently I had to connect via Ethernet in a facility that used old networking systems and I had to adjust all the proxies and IP settings manually. I had serious problems connecting with LAN eventhough all the settings and proxies were set correctly and other computers on windows were able to connect easily. I even tried to connect by restarting to Windowns 7 in bootcamp but it didn't help. The cable was a cat4 I think and after a while I noticed that in System Preferences>Network>Ethernet the cable in continuously getting connected and disconnected ( Green & Red). The IT-man there couldn't give me any advice beyond that my Network adaptor has problems or cat4 is responsible. After a while I found out if I set the configuration to Manually and set the speed in Ethernet>Advanced>Hardware>Speed to 10baseT/UTP I'll get rid of the disconnecting problem and the connection works without problem.
When I got back from that center to my original workplace I set all the settings to the original automatic setting and connected the Ethernet cable (Cat6) and at first the cable was detected (Green) but the IP address was wrong and I couldn't connect to internet. I disconnected/connected the cable 2 or 3 times and after that the Ethernet was not even connecting or detecting the cable and I had the message "Cable Unplugged". The IT team at the center couldn't help me either and the problem remained even in Windows 7 over Bootcamp.
I came to home and tried to connect with a 5e Ethernet cable to my Linksys router ( that I normally connect via Wi-Fi). But the same problem: Cable unplugged. While my brother was able to connect with the same cable with a Windows 7 based VAIO.
I tried to connect with the Ethernet cable to my brother's laptop and it gets connected and obtains an IP Address.
I tried to change the speed and duplex setting to 1000base, 100base, 10base and half and full but neither of these helped and still I get the message "Cable Unplugged" when trying to connect to router.
In system information I don't see a problem with Ethernet card and the information is as follows:
Name: ethernet
Type: Ethernet Controller
Bus: PCI
Vendor ID: 0x14e4
Device ID: 0x16b4
Subsystem Vendor ID: 0x14e4
Subsystem ID: 0x16b4
Revision ID: 0x0010
Link Width: x1
BSD name: en0
Kext name: AppleBCM5701Ethernet.kext
Firmware version: 57765-v1.37, 0x7287af41
Location: /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleB CM5701Ethernet.kext
mDNS offload capable: 3c:07:54:07:d0:d4
Version: 3.2.4b8
So I'm having the problem in different settings, with different routers and in both Mac and Winsows. I have done restarts, shutsowns, PRAM SMC resets and none helped ( neither for the ethernet problem and nor for volume and sleep problems I'm experiencing) so I'm considering reinstalling my OS X Lion. But I'm afraid it is a hardware issue because power fluctuations or something.
I appreciate any suggestion.
PS:
1.My MBP has experienced a falling down but I had no specific problem that I can relate to the strike. Also I had no problems with Ethernet after that.
2.I have a faulty Magsafe adaptor that has a corroded cable but it keeps charging and I'm waiting for my new Magsafe adaptor.
3.Newly I have a weak maximum volume on my Mac and volume fluctuations, also some weird sleep behaviours and delays in sleep...Step by Step to fix your Mac

MacBook Pro is slow on internet
I have three PCs and one MacBook Pro.
All are wireless, and I have a wireless DLink router.
I have all systems networked so I can share files and printer, and internet.
Of all my computers, the MacBook Pro is the slowest on the internet. It takes forever to download videos from the web, or even surfing is slow.
My other PCs, all wirelesslesly networked, are much faster
on the internet.
Anybody can guess why the MacBook Pro is slowest?Wireless networking is still a bit of a black art, unfortunately. I've got a MacBook Pro, a Sony Vaio TX650P and a G4 Powerbook. I have a wireless home network using a Linksys router.
Each machine has its own issues with networking. The MacBook Pro is the fastest of the three, but occasionally bogs down for no reason. The Powerbook loses connectivity frequently, even though it finds the base-station again immediately when I manually reconnect. The Vaio will work for weeks without problems, then refuse to connect for days at a time, no matter what I do, only to pick up the network and work again as if nothing had happened.
I used the MPB and the Vaio in various hotels over the past nine months, and my experience was certainly varied. Some places, both worked fine. In others, one or the other machine wouldn't connect at all, while the other one had no problems. In yet others, both would connect, but download speeds would vary widely, with no obvious cause.
On my home network, the Pro is quickest, the Vaio second and the Powerbook slowest. There's no real reason for this, as far as I can see, since each machine's WiFi speed is higher than the 4mbps cable Internet connection I use. The bottleneck should be the Net connection, therefore, not the WiFi.
I'm sorry I can't offer more concrete suggestions for a fix, but I hope my experience gives you some idea about how flaky the whole WiFi thing still is. -
My macbook pro wont do anything and it is just blowing air out the back
my macbook pro wont do anything it is using its fan rapidly
Try Reseting the PRAM, It should fix the Problem.
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

New Macbook Pro Wont turn after discharge
Hello everyone,
I just purchased my 3rd mac in the past 2 years, yeah that's how hooked I am, now windows free 99% and love it...
My brand new macbook pro has a very annoying issue.. if I use it on battery power and it discharges completely I have to wait up to 15 minutes after connecting it to power to be able to turn it back on again. this is so frustrating as I am sometimes doing some work and have to get away from the computer for a few minutes.. If it discharges within that time and I come back to continue my work guess what.. I need to wait all this time even after connecting it to power to resume my work...
Does anyone has the same problem? is this normal? I've searched google and haven't found the same problem on anyone else unless they are OK with that and just don't report it... I've never had this problem with any other laptop I own and is extremely annoying, my wife's macbook doesn't do that, if it discharges and goes to sleep you can just connect the magsafe adapter and it will come right back up.
your comments will be greatly appreciated.My MBP has always come back immediately. So has my old iBook. I rarely discharge my battery completely, but will do so on occasion to calibrate it. But I have never had the problem you describe. My personal opinion is that the long delay is definitely not normal.
Out of curiosity, next time your Mac shuts down like this, remove the battery and see if it will start up immediately. If it does, you could possibly have a faulty battery. If it still takes a lot of time to start up with the battery removed, there is something else wrong. I have never heard of anything quite like this. Since you didn't mention excessive heat, that wouldn't be a factor.
Be sure you can reproduce the condition for the Apple genius. They have to see it to be able to do anything. Go in a bit early with a low battery and run it out in the store, so you can show them exactly what it is doing.
Good luck! -
New macbook pro wont accept password
I moved everything over from my i5 MBP to a new i7 via utilities migration assistant. However the new macbook pro wont accept my password, nor will it recognise the other user account passwords. Works fine on the i5.
In Disc Utilities, change password asks me to select an image, but does not light up "change" when I select user.
Any ideas?Is you new MBP the 2010 model or is it a newer model running Mountain Lion?
If it's a newer model running ML, you can simply boot into your Recovery partition (hold down the Command and R keys whilst booting) and when you get to the Recovery window, select Terminal from the Utilities menu. In Terminal, type
resetpassword
and hit Return. A small app will open that will allow you to change the password for the user that you select. Then just reboot and use the new password.
If, indeed, you're running 10.6.4, you'll need the installation disc to use the Reset password utility.
Good luck,

Hi there,
I have a macbook pro mid 2012 non retina display and i tried using an external display for it. I hooked it up and the screen blacked out and turned back on like normal and the computer itself was reading that the display was there. The only problem is that on the display itself there is no image of the macbook being displayed. im using a thunderbolt to vga connector and all the connection check out the only problem is the display. the display works on my other macbook that i have just fine i dont understand why it wouldnt work on this new one. Keep in mind i have had this computer for only 5 days.
Thanks in AdvanceHi, cubingcouple.
Thank you for visiting Apple Support Communities.
I understand that your MacBook is not working with your external display. display shows a blank screen. Here is the best troubleshooting resource to go through when experiencing these symptoms.
