MacBook Pro won't upload files to Internet

Just got a MacBook Pro. It hasn't been able to upload pics, attachments to any website. Facebook, Gmail, Google+, ect. It was like this out of the box. I have tried Mountain Lion, Mavericks & Yosemite Beta 2 and then Internet Recovery back to Mountain Lion & currently on Mavericks. Same on all OS versions. Also the same on Chrome, Firefox & Opera. Tried 2 different routers..same results. No other device on my network has this issue. In a Facebook message it will send stickers but not photos or files. The photo & attachment progress bars on Facebook, Gmail, ect get stuck at about 50% after hitting send and then fail. The firewall is off. Downloads are perfect.

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

My MacBook Pro won't connect to the Internet, but my phone and PC will.

My MacBook Pro won't connect to the Internet. My iPhone has no problem doing so, and neither does my PC. I think it's something to do with my DNS, but I'm not sure. My network connections say that both my Ethernet or FireWire are failed. What's wrong with my MacBook? Is there a simple way to fix this?

Hello Rattisate,
Sorry to hear you are not able to connect to Wi-Fi on your MacBook Pro. I would be concerned about this too. You can find information on how to troubleshoot this in the following article:

Macbook Pro won't connect to the Internet anymore.

I am posting on behalf of a friend.
She has a MacBook Pro 13" Early 2011 model. She can connect to Wifi and Ethernet cables fine, But when it comes to using the internet it won't work.
She tried Safari, Firefox and Chrome, and other software that uses internet connectivity doesn't work.
We used different internet connections, restarting the Laptop but it wouldn't work.
She upgraded to Mac OS X Yosemite, see it would fix the problem but again, nothing.
The Odd thing about it is that she has two account in the MacBook Pro, The Other account being her sisters, does get internet connectivity and browses the internet with no problem.
We made a new account and see if that would do the trick but still does the same thing. No internet connection.
Any suggestions how to fix this?

I tried re-installing Mountain Lion 10.8.3 but it didn´t help.
Assuming your can access email ok ?
First, install the OS X Mountain Lion Update v10.8.4 (Combo)
Then restart your Mac. That will reinstall any missing system files.
Then try Safari.

MacBook Pro Won't Connect to the Internet

Hi hi. Okay, I've noticed this unusual behavior in my MacBook Pro (Intel Core Duo, 2.4 GhZ, 15-inch, probabl 2 months old now) just last night. It connects to the wireless network but will not load any webpages. If I type in www.google.com or so, it says Contacting "www.google.com" and it stays on it and the page remains blank. I'm writing this from my MacBook which seems to connect fine to this wireless network. The problem persists in the MacBook Pro when I'm on XP (boot camp) and when I'm on Leopard. I've restarted the machine and everything but it still occurs. Prior to me discovering the problem, I think the MacBook Pro was asleep for 2 days (in XP).
I've opened Network Diagnostics in Leopard and it detects the wireless network and everything but then it says it needs a WEP password. But the MacBook can join this same network without a password. I access the university network (from a dorm) so while you don't have to have a password to connect to the internet, you only log in when you open an internet browser and then sign in with the student ID (but its not the WEP password, if that makes sense). Basically, I can't acess the internet if I don't log into the internet and of course even the university login page won't show up. Can anyone please help me? It's driving me nuts. Thanks!
P.S.- I've been hearing other MBP users having this problem but I don't know if I installed the Airport Update, and restarting doesn't help either.

GStreakT:
Your OS is shown as 10.4.7, but most people who are having problems similar to yours have later versions of Tiger or Leopard. If you're running a later version than 10.4.7, please update your settings for this.
Some people, including me, have found that setting the router to "G-only" mode solves the problem (at least until Apple fixes the problem in a software release.) Please post a reply or email me as to whether this works for you.
TIA

Brand new Macbook Pro won't connect to wireless internet

Hi all, I'm relatively new to the whole mac thing, but I have a problem. I got a macbook pro for college last week, and have been struggling to connect to the internet ever since. I notice other's are having issues too.
So here's what's going on:
When I set my pro to using DHCP, I get no IP address, or sometimes get the self assigned address 169.etc. Yet when I put in a static address, subnet mask and router info I've found for my network, It says connected but when i click on safari no internet. I've run diagnostic in safari and all the lights go green (under manual ip etc) except internet and server (which are yellow). What's going on here? It can't be the airport card, because my pro connects seamlessly to my college's wifi, my ethernet cable and rogers internet stick. So is it my modem/router combo (using a siemens SE567), or is it because I'm running 10.6.4?
Please help, I have to use the internet for uploading videos and other heavy internet usages that my internet stick can't do (unless I want a $100 bill each month), and being tethered to my ethernet is kind of a bother.
*I should also note I have a pc laptop that runs fine off the network (siemens se567), though setting it up also gave me issues.*
Thanks

I'd suggest you repost over in MacBook Pro forum, and in Using OS X Networking.

My one-month old MacBook Pro won't connect to the internet?

I called the service provider, it is neither our modem nor our internet. The PCs in the house work fine, but a couple housemates and myself own Macbooks, and although they find the network, they do not connect. I've heard it's just some problem that randomly occurs for Macbook users and has no actual solution other than luck. I was wondering if this is a false rumour, and how to go about fixing it? I've reset the modem, router, and computer multiple times to no avail. If this is true, I will be the first one in line to sell my Macbook Pro back.

My macbook pro won't connect to the internet. Tried everything? Please help ...

Although both Airport and ethermet connection seem to be fine (green indication in network diagmostics) and all other computers in the house will connect to the net just fine, my macbook pro will not. I have reset the router several times, restarted the macbook, tried to remove airport, I have run all diagnositics, created new networks etc etc.
What happens is that during network diagmostics, airport and wifi settings appear green, while network turns yellow and stays yellow.
When i go into the advanced network settings menu under tcp/ip, there is an ipv4 address as well as a subnet mask address, but nothing after router:
All other macs in the house (e.g. my girlfriend's nearly identical kmacbook pro) show up the router as 192.168.1.1
My settings are in Norwegian, so I am translating what i read on the screen - please bear with me ...
Thank you for all your help!!!

My Macbook Pro won´t connect to the Internet

I've been ytring to log on to the Internet for several hours via wireless with no luck. It connects to Wi-Fi with no problem, but it simply refuses to connect to Internet. In the diagnostic, on the left side there are several red/green lights for status. Wi-Fi, Adust Wi-Fi, and Internet Provider are all green. Network Adjust is in yellow, and Internet and Server both have red lights with an ´error´ notation below them.
When I try to go through the steps of the diagnostic, it asks me what sort of Configuration I'd like to use, and I select Wi-Fi. It then asks me if I am using a cable or ethernet, and I click no, at which point a box opens up saying my problem is impossible to fix, and Network Adjustment and Internet Provider lights both become red.
I came to this discussion board for help, and one posting said to remove AirPort and then put it back. I removed it, and I can't even find it now.
In Ecuador these laptops cost $1500, and I am very frustrated because this is a ton of money for me. I bought what I assumed to be the top of the line, but now I am very much regretting this decision. If anyone know

Let's try the simple approach first. Restart your router. Any change?

Macbook Pro won't receive files via bluetooth

Strangely, I can browse devices, and send to them, but never receive from anyone's phone including my own. It seems one way.
I have deleted all relevant preferences. Phones, etc. are paired, and the Macbook is discoverable, but a phone always says "send error", and the bluetooth activity sign appears on the Mac menubar, and then reverts to normal immediately.
Any thoughts as to the best troubleshooting pathway for this over what I have done already?
Many thanks.

MacBook Pro won't play .mov or .wmv files.

Since "upgrading" to Lion my MacBook Pro won't play .mov or .wmv files, all I get is a black screen and the audio. It's so frustrating!!
I've read many other posts all along the same lines and wherever possible I've tried to follow the advice which has been given but nothing works.    I've updated all the drivers I can and I've even reinstalled Lion, nothing makes a difference.
I'm not really looking for any more advice, all I want is someone from Apple to read these posts, realise there is problem and get working on a fix or update.
I had no problems when running Snow Leopard and it would seem, looking at everyone else's problems, that the common issue is Lion.   Seriously, this is one area where Lion is a backwards step.   It should just work (like most things from Apple), but it doesn't.
Personally I believe there is a problem with Lion but from what I've found out from speaking to friends with other Apple kit, this might be a random issue only affecting some people as some have said they've had no problems while others have had the same issues as me.    One guy reinstalled Lion and it resolved the issue for him, I've not been as lucky.
As I say, I'm not really looking for more advice, simply some sort of update from Apple to fix it.   PLEASE!!!

This is a peer-to-peer user forum. Perhaps you would see more action if you and others would file a formal "Bug" report with Apple QuickTime technical people rather than repeatedly reporting a possible problematic problem which may or may not affect others on a random basis. QUICKTIME PRODUCT FEEDBACK
Since you aren't seeking further advice here is what I have observed. Not being a regular WMV file user, I had to create my own sample file to test—a WMV 9 file containing WMV3 compressed video and WMA2 compressed audio. Since I normally use QT 7 as my primary media player, I also stored the WMV data in its partially decompressed form in an MOV file container to avoid pre-playback delays in "classic" player routines and also provide a secondary playback test of MOV wrapped content. These files play as follows using the Flip4Mac component/player support and uncoded URL uploads:
QT 7.6.6 "Open File" - both files play correctly.
QT 7.6.6 "Open URL" - both files play correctly.
QT X.1 "Open File" - WMV file plays correctly. MOV file plays video without audio.
QT X.1 "Open Location" - WMV file appears to open but plays with "black" screen and no audio. MOV file plays video without audio.
VLC "Open File" - WMV plays correctly. MOV file doesn't open,
VLC "Open URL" - WMV file plays correctly. MOV file appears to open but nothing plays.
MPEG Streamclip "Open File" - both files play correctly.
MPEG Streamclip "Open URL" - both files play correctly.
GarageBand - WMV file will not import but MOV file does.
iTunes - WMV file will not import. MOV file container is accepted but as soon as iTuness sees the compression formats, it aborts import.
Safari - WMV file URL auto-downloads and playes in the QT X.1 Player. The MOV file URL opens and plays in Safari.
As you can see from these results the files do play but are subject to many different constrints based on old/new video technology support, independent QT subsets and/or container trapping constraints. In short, individual user results will depend on presence/absence of component support, actual compression formats, file container, application being used, and how the application is being used. Unfortunately, most users here can't or won't provide the prerequisite information or a sample file for independent examination. This makes it next to impossible to give advice in these matters or categorize the specific nature of the problem.

My MacBook Pro won't go beyond a white screen, after I pushed the restart button. How can I get it to a login? I have routinely backed it up, but don't know how to bring that up, nor if I have a boot file on that external disk. Help!

My MacBook Pro won't go beyond a white screen, after I pushed the restart button. How can I get it to a login? I have routinely backed it up, but don't know how to bring that up, nor if I have a boot file on that external disk. Help!

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Install or Reinstall Yosemite, Mavericks, Mountain Lion, or Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
How to Clean Install OS X Yosemite
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

My MacBook Pro won't load any websites on Safari (except this site, Facebook and Google), Opera, or Mozilla Firefox. I already did the "Reset Safari", restarted the computer half a dozen times, and I can't find this alleged "caches.db" file to delete.

My MacBook Pro won't load any websites on Safari (except this site, Facebook and Google). Opera and Mozilla Firefox won't load any sites whatsoever. I already did the "Reset Safari" several times, restarted the computer half a dozen times, and I can't find this alleged "caches.db" file to delete. I virus scanned the computer with Sophos, Avast, and iAntiVirus and it looks clean.

Is iAntiVirus the best virus protection to use for a MacBook?
The best anti-virus protection is your own common sense, and what you already bought and paid for with your Mac. Third party products such as "iAntiVirus" convey no additional benefit, and as you already determined are very capable of causing trouble.
OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Java can be disabled in System Preferences.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.
