My MacBook pro will not connect to the Internet through wifi yet all other devices do

My MacBook pro will not connect to the Internet through wifi. I have several other wifi enabled devices and they are all connected to the Internet just fine... What could/would cause this?

Disable your AirPort and enable in a second. Or check, maybe you need to type in correct digits in; Settings/Network/Advanced/Configure...

My Macbook Pro will not connect to the internet or bring up Safari!

For the past couple of weeks my Macbook Pro has been having issues connecting to the internet and when it is connected it won't bring up Safari "You are not connected to the internet"
I use the correct password for my wireless internet and it still won't connect. I deleted the airport in system preferences and then made a new one. It connected for a few minutes but then disconnected and just shows an explanation point over the airport sign at the top of my status bar.
PLEASE HELP ME.
I run a business and not having access to the internet on my Macbook is very very stressful.
I brought the Macbook into the Apple store but of course it works perfectly when I bring it in there... HELP

I also just realized it's also saying under the Airport status in System Preferences that the "AirPort has the self-assigned IP address ###.###.##.### and will not be able to connect to the internet."

Why is my MacBook Pro safari not connecting to the internet?

The past week I have been trying to use Safari on my MacBook Pro but it keeps saying Safari can't verify the identity of the website. I am not sure how to get rid of the popup, so I can continue to use the website. What do I need to do to resolve this?

Which website? Is it one in particular, or dose it appear on every website?
When you open Safari, does it always open with this site?

I even tried downloading google chrome from my girlfriends mac book and moved to my computer via flash drive but still no go on the internet. Please help me.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal 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 Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
Copy (command-C) the selected text to the Clipboard. Then click anywhere in the Terminal window and paste (command-V). Post the lines of output (if any) that appear below what you just entered. You can do that by copy-and-paste as well. Omit the final line ending in “$”. No typing is involved in this step.
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}'
This time you'll be prompted for your login password, which you do have to type. It won't be displayed when you type it. Type it carefully and then press return. You may get a one-time warning not to screw up. You don't need to post the warning. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}'
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

My MacBook pro will not connect to the internet, be it via the airport or ethernet at any location.

I have been on the phone with tech support, and have been to the Apple Store 3 times already. Each time I have brought the computer to the store, the internet will work. The workers say the store is 'magic.' However upon leaving the Apple store, the internet will not work be it at Starbucks or home. On my last visit to the store, they backed up everything on Time Machine, cleared the computer, and reinstalled OS, but I still cannot connect.
I'm at my wit's end and could use any help available. Thanks!

Turn off your Firewall, to eliminate that as a problem. System Preferences > Security > Firewall
Check to see if the router you are plugging into doesn't have MAC filtering activated.
Make sure your IP is not the same as another computer or router on your network.
If you have manually put those details in, see if you can set it to "Using DHCP"
System Preferences > Network
Are you using a Proxy? Make sure that is turned off in Advanced.
Is firefox / Safari in the Preferences under Advanced & Network - set up correctly?

My Macbook Pro will not connect to the internet.

Randomly, my Mac stopped connecting to my wifi network 2 days ago and now it will also no longer open safari or other internet based apps.
My network icon is always 'searching'. I can find my network occasionally and the status will be connected, but the icon remains searching and no internet is let through on to my mac.
I've tried the usual diagnostics but it replies my password or network name is wrong although it is correct. When I look in 'airport', nothing is found. No addresses are in my TCP/IP information, nothing in my DNS tab, no proxies boxes selected.
I have powered down my mac and routed numerous times and turned wifi on and off no end. All other apple hardware connects well.

When you see an exclamation point in the Wi-Fi menu, from the menu bar, select

Click the Assist me button and select Assistant. Follow the prompts. You may get a warning that Wi-Fi is not available, that you're too far from the base station, or that you're using the wrong password.
Assuming that you've ruled out those possibilities, click the lock icon in the lower left corner of the preference pane and authenticate, if necessary. From the Location menu at the top of the window, 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.

My macbook pro will not connect to the internet, help pleaaaase?

I have literally been to countless forums and nothing has worked. I restarted the router for the internet, but every other computer in my house is connecting to the internet just fine. I don't know what to do, and this is incredibly frustrating. Can anybody help me?

Is your computer still authorized in the Store menu in iTunes?

When I changed to my new MacBookPro I had to authorize it although I used TimeMachine to transfer my settings and data.

iCloud is only available in Lion, 10.7. You will have to upgrade to Lion in order to get into iCloud. If you transfered a .mac or .me address to iCloud through mobile me, or you have another device iCloud enabled, then you can log into the iCloud.com website.

Mid-2009 Macbook Pro will not turn on

Hi Folks,
so my mid-2009 15in Macbook Pro will not turn on. I updated the OS to Mavericks in December 2013. I'm from California, but I recently moved to the Guam/Marianas area where it is more humid and generally around 87 degrees F all day. For the past month my computer has worked fine, albeit I did notice the fan was running a little more than usual. I usually would just put it into sleep mode when I would finish using it (apparently a bad idea based off of reading other posts concerning humidity and, more importantly, heat). One day I finished using it, closed it and the next day went to open it; I could hear the fans start to work, but then it stopped. It hasn't turned on since. You press the power button and nothing happens. I tried all the troubleshooting stuff.
So, my question is this: what do you think is the problem? Moreover, how much do you think it could cost to repair it? My experience with computers suggests to me that it's probably a dead motherboard. I'm wondering if it's worth trying to salvage this thing or if it would be prohibitively expensive. There are no Apple stores in the area to take it in to get advice unfortunately.
Now, I just want to vent a little frustration. I have many apple products, and I've even switched my mother over to an apple computer, but now that I need some very basic support, apple doesn't provide a contact e-mail or a free chat? I think charging someone $19 for 'one time assistance' is ludicrous. I bet if I brought this into an apple store I could at least get some advice, and thus get some idea how I want to proceed with repairs or not. I suppose I'm also rather frustrated that my macbook, which I have been most happy with all these years, breaks because I go somewhere a little more humid and generally warmer? It would appear that the hardware failure is connected to the climate. This makes me skeptical about purchasing another mac if it can't handle a little humidity. (I have not spilled liquids on it, nor have used this computer while transitioning from an air-conditioned/humid location which could potentially cause condensation). I do not think I'm being unreasonable (yes I do think a $2500 computer should not fail after less than 5 years), but if you think I am unreasonable, please enlighten me.
Thanks for any help. I really appreciate it.
Ken

Ken,
the “Important Handling Information” in the little white manual that came in the box with your MacBook Pro states that its operating temperature range is from 50 °F to 95 °F (10 °C to 35 °C), and that its operating range of relative humidity is 5% to 90% (non-condensing). If your corner of the Pacific is outside of these ranges, the manual states that “Failure to follow these handling instructions could result in damage to your MacBook Pro”.
I have no idea what problem your MacBook Pro has; since you’ve tried all of the troubleshooting stuff, you’ll need to somehow get your MacBook Pro to a qualified service facility to diagnose the problem. If the logic board does need to be replaced, it would probably cost hundreds of dollars for a replacement, and you might find that purchasing a replacement used MacBook Pro of the same model to be price-competitive with just replacing your MacBook Pro’s logic board.
If you find Apple’s out-of-warranty policies unacceptable, then your only alternative to venting would be to purchase your next computer from a different company which has out-of-warranty policies more to your taste.

Mid 2010 Macbook Pro will not stay off or asleep

Hi,
I have a mid 2010 MacBook Pro will not stay turned off when I tell it to shut down. It will shut down just fine, but a few seconds later it will boot up again. This also happens when I try to close the lid (or just put it to sleep), it will work fine, screen/Apple logo on the back will turn off and the status LED will slowly pulse. However a few seconds later, the LED stops pulsing and the Apple logo will illuminate. If I open the lid I will be greeted with the log in page with zero delay (i.e. its been displaying for a while).
This has become problematic because the computer always be running. If I put it in my laptop bag the computer will get hot as ****. The only way to get it to really turn off is to let the battery die or remove the battery. But this computer does not have the externally removable battery so that is not a trivial process.
The symptoms exist in both Mac OS (Mountain Lion and Maveriks) and Windows 8/8.1. This makes me believe its something in the hardware (or at least a setting in the hardware), not software (I know Apple doesn't care what Windows does, but it is exibiting identical behavior).
I have reset the NVRAM and the SMC with no luck. When I reset the SMC I didn't get a good indication that anything happened though, and was wondering if that is normal. Resetting the NVRAM results in another restart, while its hard to tell if you actually reset the SMC. I reset the SMC by turning the computer off, then holding the power button when it tries to restart (this usually gives me a few minutes where the computer will actually stay off), then pressing shift, control, option and power at the same time and releasing them at the same time. This is how the Apple documentation said to do it. They did not mention how long the must be held though so I presume that doesn't matter.
Anyone experience this/have any ideas?
Thanks,
Jim

My Mid 2010 MacBook Pro will not boot

My Mid 2010 MacBook Pro will not boot regularly, in safe mode, in recovery mode or from original OS DVD. Is this the logic board?
I've tried resetting the SMC and pram numerous times and even tried switching out hdd's to try and do a clean install on a new hdd.
If I attempt to boot regularly or from recovery drive the grey apple logo appears for a period before the screen goes black and the power LED operates as though in 'sleep' mode. I'm unable to wake it from this state and the same applies to booting in safe mode.
When attempting to boot from the OS DVD that was originally packed with the computer it just freezes on the language select option, this occurs with the other hdd's I have attempted to use.
Any other suggestions to get it working? I fear the logic board has gone and that the repair won't be worth the money.
Thank you in advance.

Hi JRC8.8,
It sounds like you have been on the right track in trying to troubleshoot this issue. You may want to see if your MacBook Pro will boot directly to the Apple Hardware Test, as outlined in the following article:

The sound on my macbook pro is not working

The sound on my macbook pro is not working. When I increase the sound, the icon appears as if everything is working, but no sound comes from the speakers. Earphones don't work either. I have tried a PRAM reset but at times, this doesn't even work. It's really frustrating having to restart my computer every time I want the sound to work, and even when I do that, theres a 50 50 chance of it working again. It generally happens after my laptop goes to sleep and I wake it up. Has anyone else had this problem and fixed it or even know what caused it?
There are a lot of discussions around the earphone jack but I have checked that. I've tried a PRAM reset which hasn't worked, and my sound output is set to Internal speakers.
HELP!!

Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers / Headphones
    Make sure Mute is not enabled.
2. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
3. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
4. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.
