No internet connection MBP Retina

All to often I get the message No internet connection on my MacBook Pro Retina (13").
It's connected to the local network but won't reach the internet. (I do get an IP address etc, but the AirPort logo just shows an !
I can reach the internet on other computer, iPhone or iPads so this is just a problem with the MBP.
If re starting the computer a couple of time this sometimes solve the problem when occurred. Today nothing would fix it.
Anyone knows if there's a fix for this?
Thank you.

So the iPad and iPhone is connecting via the same wifi and going online with no trouble, but the MacBook Pro is not.
Usually when this occurs one resets the modem/router and it establishes a new lease with the ISP, so try this first and reboot the Mac.
Have you tried another browser, user account and different browsers in that account?
Have you tried using a Ethernet cable to the router or modem (power on/off) to see if it's a Wifi issue or not?
Some ISP's are testing iPV6, Mac's have it turned on and if the ISP is testing it this can cause issues, turn it off in your Network preferences and reboot.
If your Mac got compromised by malware it might have been blacklisted, but this is rare but it occurs on Mac's, but it can happen more often if one is running Windows.

Connect MBP Retina to Pioneer Receiver no HDMI Audio

I'm connecting my MBP Retina using the HDMI cable to my Pioneer SC-68 receiver. The video works fine and displays great on the TV, but I don't get the option as to selecting the HDMI as an audio sound output. My only two options are Internal Speakers and SC-68 Airplay, which I figure the two linked up over the network by themselves.
I can use Airplay mode, but then I get no video on the screen.
Any ideas? Is Apply blocking the audio on the HDMI or choosing not to support it in favor of their Apple TV?

I'm also having this problem. I briefly saw the SC-LX86 (EU version of the SC68, lovely Receiver btw) option in my Sound preferences today after installing an SMC update, but my rMBP froze shortly after requiring a hard reset and the option had gone on reboot. Very frustrating.

My MBP keeps dropping the internet connection

Since yesterday, my MBP (Late 2011) keeps dropping the internet connection from my Airport Express. I'm still connected to the network, it just loses the internet connection on the MBP. I restart the computer, and it works for a few minutes. I turn off router, and it works for a few mimutes...but no matter what I do, after 2-3 minutes, I get the exclamation mark in the wifi indicator saying there is no internet connection.
And this is only happening on that single MBP. All of the other devices in the house, another MBP (mid 2012), an iPad (retina with lightning connector) and 2 iPhones (one 4 and one 5), can all connect. And the router we have is an airport express.
Why is this happeneing only on the one computer, and how can I fix this?
Thanks.

First, changing your DNS settings could not possibly have any effect on this problem.
When you see an exclamation point in the Wi-Fi menu, from the menu bar, select
 ▹ System Preferences... ▹ Network
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.

MBP retina slow Safari when connected to Buffalo

Hi.
I am new to Mac world. I recenlty purchased MBP retina. As soon as I brought to home I connected to WIFI (broadcasted by Buffalo WZR-HP-G450H) and noticed very slow Safari despite uncompromized internet connection. It is always written Sending request at bottom left corner of the Chrome window (same in Safari).
I checked on Windows machine, ipad and and experienced instantanous page loading. I switched back to old TP-Link and got very fast page loading in Safari and Chrome as well. It is very frustrating because I need Buffalo for transfering HD videos wireleslly to my TV and cant use the old TP-link router.
So, could you tell me what is the problem that MBP retina' is very slow downloading pages on Buffalo but quick on old router? Am I destined to have slow brosing speed on Retina?
Thanks for your help.

This isn't customer support - this is a user-to-user forum. You can contact Apple's customer support by calling the AppleCare phone number: find your country here - http://support.apple.com/kb/HE57.
I don't know anything about Buffalo routers - but it sounds as if the router is the problem, since your 'old' router works well.
Sorry,

MBP retina + Yosemite + MAGSAFE CONNECTED = freeze and spinning ball!!

I'm really losing my mind...
Friday I finally installed Yosemite 10.10 on my mbp retina. At the beginning everything was perfect, then new updates like iphoto and imovie started to pop up so I decided to download them. At some point of the download the spinning ball appeared but didn't want to go away, even after 5 minutes. I couldn't use my macbook so I decided to force shut down.
After restarting I could log in, but as soon as I moved the cursor to the dock and clicked on the apps I needed to open (Mail and Chorme) everything froze and the spinning ball appeared again.
Force shut down again.
The magsafe was connected at all time.
Then I decided to go to the Apple Store to solve the problem. Once I explained the problem to the guy and turned on the macbook in front of him, everything started to work again perfectly.
I looked like a freaking idiot.
He had no explanation, he just told me to use time machine to backup my data and bring the macbook there in case the issue would appear again.
Yes I tried all the possible procedures pressing the keys when the macbook is turned on. (I kept for last the pram reset and smc reset)
Nothing.
Then this morning I realized the freezing at startup would occur only if the magsafe was connected!!! This is also why at the Apple store there was no problem at startup....no magsafe connected. I tried a few times to use the macbook normally with the battery (even now that I'm writing), and it's working perfectly!! But as soon as I connect the magsafe, go to the dock to open apps or simply click on the google chrome tabs to type in a website, everything starts to freeze again and the spinning ball stays there indefinitely.
I also tried the utility disc (in normal and safe mode). It says everything is ok.
I even tried to delete completely iphoto, imovie and caffeine and to reinstall Yosemite.
I don't want to go to the Apple Store now because it's full of people (iphone 6 just got released here in China).
Could someone help me understand what is the problem??
Thank you for all the help you can provide

Yesterday it started to do the same even with the battery! So it was impossible for me to use it. I went to the apple store...they didn't know what to tell me since the system just got released.
They ran a few tests on my macbook and it showed that it wasn't an hardware issue, it was the software. So they wanted to do a backup of my data (from one of their macbooks) but couldn't because somehow there was a password for Firevault. I never put it!! And it's not the same I always choose for my system.
Result? They had to erase everything (I'm angry because I lost a lot of my work files) and now I'm back to Mavericks 10.9.5 and I have no idea when I'll decide to update again to Yosemite.
Since Steve Jobs passed away Apple is not the same.
My girlfriend has an iphone 5, she installed IOS 8 and everything is slow as ****. Seriously.
It's really disappointing and I (we) don't trust Apple anymore.

What is the best way to connect MBP 13" - (non retina) to HDMI TV input

What is the best way to connect MBP 13" late 2012 - (non retina) to HDMI TV input
...To get Video and Audio? With one cable ...
I'm seeing that the "rocketfish" adapter is not handling the job (from these forums).
I enjoy watching youtube videos, hulu, etc on the big screen through my laptop. The other Windows laptops I'ved had from Sony, HP, Dell, all had HDMI and was easy peasy.
I don't have the patience to buy and return 10 different types of adaters (nor would Best Buy appreciate that)
Thank you!

Look for something like this:

Suddenly, my MBP Won't get an internet connection through my routers

I've had my MBP 15" 2.4 for about three months now, and I've never had a problem connecting to the internet. This morning I booted it up, but when I went to get on a wireless connection it would connect, but still say I had no internet. I have two routers in my house - the main one on one side, and my old iMac in my room (my room is too far from the main router to get signal), and the MBP won't get internet from either. However, as you can see by me posting this topic, I'm getting clear internet through the ethernet cable. An error message in connecting to the wireless signal has also appeared a few times. Lastly, my MBP is running very slowly this morning, and there's lots of lag for the track pad.
At first, I thought it was the main router's problem. But since the iMac's Airport isn't providing internet connection either, it leads me to believe it's something with the MBP. I'm not sure what to do, and I'd greatly appreciate any help I could get.

Sorry to hear about the signal dropping. I don't have a solution but would like hear if anyone has an idea what's going on.
My situation is similar. I have an Airport Extreme (n) and the MBP would drop its connection to it randomly. I've gone to pains to change my phone from using any close freq to the wireless.

13" MBP internet connection gets disconnected when too many wifi connection's available

I just notice this a couple of nights ago... Im using a 13" MBP I bought last June 9. At night, when there are plenty of wifi connections being broadcast in our condominium bldg, my internet connection is very slow. Also, the signal strength is reduced to half. Sometimes I even get disconnected and the MBP wifi has difficulty reconnecting my wifi. But when morning comes, signal strength is at full. I ask my friend who also connects to the same wifi if ever he has difficulty connecting at night, but unfortunately its just me. He is using windows, by the way. I'm wondering if this is a known issue and have a fix already? or it's just me?
Please help... Thanks.

I use my 15" MBP this way with no problems at all and I have Mountain Lion installed. So we need to look elsewhere for the problem, it's not possible to link this to the OS without further investigation (but it could be a system setting).
I know that other folks are complaining that Mountain Lion broke WIFI. But if that were the case we would all have problems. I, along with many others, have no problems at all. I think there is something else going on.
What is the signal strength with the lid open vs. closed?
When you say that Safari does not work, are you getting a timeout message or a message like "You are not connected to the Internet."? Of course this is the English version of the message, yours will be different.

I have a MBP Retina and in the office I use it with a Monitor Sony LMD-2450W connected through AMD Port to VGA. After installing 10.9.2 the resolution in the monitor has been downsized to 4:3 (and 1280x960) instead of its 16:9 display. Anyone know how to

I have a MBP Retina LCD (resolution 2880x1800) and in the office I use it with a Monitor Sony LMD-2450W connected by VGA. After installing 10.9.2 the resolution in the monitor has been downsized to 4:3 (and 1280x960) instead of its 16:9 display. Anyone know how can I change the resolution manually?
Display shows only 3 different resolution if I choose "scaled" but none use the full area of the monitor.
Thank you

This has been an ongoing problem with external monitors that predates 10.9.2. I wrote various tips on different methods here, though the best is probably the hot corner one:

I have a MBP retina and I am having problem when my bluetooth and wifi are both active. My wifi is totally unusable when I am connected to via bluetooth speaker.

I have a MBP retina and I am having problem when my bluetooth and wifi are both active. My wifi is totally unusable when I am connected to via bluetooth speaker.

Chances are you mis-typed a character in the Wifi password and the devices saved that information. Now whenever you try to connect the device refers to the wrong password and the Jetpack does not accept your connection. Tell your devices to forget the wireless connection and start over.
Once you enter the proper WiFi credentials the Jetpack will allow you to connect.

Why the super slow internet connection on my MBP?

This falls into the category of FYI, or FWIW. I'm going to answer my question for the good of the community,
I suddenly noticed a significant reduction in my internet connection at home on my MacBookPro. According to speakeasy.net/speedtest I was getting over 11 Mbps down and 1.5 up before then suddenly I was down to 1 Mbps downloads and .25 uploads. I tried 3 browsers and an scp transfer via the terminal from my web server and all with the same results.
However, the mystery deepened when I tested other computers in the house and they were getting the original 11 Mbps. So, I took my computer downstairs next to the router and also got the original 11 Mbps. So, I went back upstairs, but instead of plugging in my old 23" Cinema display, I tested without. You know what happened, right? Yup, 11 Mbps. Plugged in the Cinema display and back down to 1 Mbps.
I have no idea what is going on, other something in the Cinema display is interferring with my wireless connection.

AirPort and Bluetooth: Potential sources of wireless interference

I am using a GLOBE prepaid microsim for my new ipad with retina. i was registered with supersurf 999, and i was able to enjoy my internet connection until i updated my ios with 6.1... every time i go online,it says i am not registered with mobile intrnet?

i am using a GLOBE prepaid microsim for my new ipad with retina. i was registered with supersurf 999, and i was able to enjoy my internet connection until i updated my ios with 6.1... since then, every time i go online,it says i am not registered with mobile internet... however, when i insert the microsim on my broadband, i can actually go online... what to do??? my apn setting in internet.globe.com.ph which is for prepaid users...

PS - I just sent this to a few of my friends in the big hardware review sites, as well as a few apple execs:
Whats up guys? Its your old buddy dom "battleship mtron author , 9 ssd drives in raid 0" years ago. lol
I wanted to fill you in on a HUGE problem with the new ios 6 update.
My iphone 4 updated without a hitch.
My ipad 3 on the other hand has a HUGE PROBLEM. It is essentially a brick without wifi (since the device relies on wifi for just about every task).
There are currently hundreds of a users within the last 2 hours reporting the same error on the apple discussions site.
https://discussions.apple.com/message/19626235#19626235
What happens is simple:
1. Download and install the update on Ipad 3.
2. Try and connect to your normal wifi connection.
3. It will connect for a few seconds and than fail stating "no internet connection available"
4. It is no a brick without wifi accessibility. (unless we revert to ios 5)
I have tried resetting my router. Resetting settings on the ipad. Renewing the ip address both LOCALLY and through the WAN at the cable modem and rebooting all of my networking equipment (ie: router), I even tried doing a complete wipe and re-install of ios 6 fresh. You guys know I am a tech geek from my background and I have tried everything so I just wanted to fill you in on this potential problem for apple.

My internet connection is intermittent with my MBP but it's fine with my iPad. What's up with that?

Back up all data before making any changes.
Step 1
Take all the applicable steps in this support article.
Step 2
If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
If the application called "Bluetooth Setup Assistant" is running, quit it.
Step 4
This step will erase all your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 5
Reset the System Management Controller.
Step 6
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.

MBP 13" 2.53 Ghz: with FW800 drive connected the Wi-Fi Internet connection

I have a brand new MBP 13" (2.53 Ghz) connected via Wi-Fi to Internet.
If I connect a 320 GB Lacie external Hard drive to the FW800 port, the Internet connection is lost.
I use a 800-to-400 cable and i have no problem on another MBP 15,4" and on my MacPro latest generation.

Ok I made the test and followed your instructions. Unfortunately I did not found the files I marked strikethrough. Conclusion: it didn't help. Sorry. My router lose the connection and restart itself when I load big file.

Since upgrading to Lion my iMac (Intel Core 2 Duo 2,4 GHz) frequently looses connection to the internet. Wi-Fi signal is still displayed as very strong but there is no data transmission.
As you are upgraded from 10.6.8 to Lion, that may help:
Switch off wifi on the machine.
Then go on and delete the bold printed files mentioned below. As you are using Lion, the Library is hidden. You have to use "go to" - "go to folder" on finder (menu bar) to access them.
You will find the files on your system drive (not your home folder) as follow:
/library/preferences/com.apple.preferences.accounts.plist
/library/preferences/com.apple.preferences.sharing.plist
/library/preferences/SstemConfiguration/preferences.plist
/library/preferences/SstemConfiguration/com.apple.airport.preferences.plist
If there are files in this folders with the same name but additional .orig at the end, delete them too.
On the wireless section of the system settings uncheck "Ask to join new networks"
Reboot the machine.
Join your wireless again.
