Macbook Pro cursor disappears when connected to TV

I have a Macbook Pro, the cursor is going out and turning into a weird flashing slashed/dotted black line on my screen everytime I connect my Macbook to my TV with the mini display port adapter connected to a VGA cable. I use it to watch movies on my TV through my mac. I haven't had any problems at all with it, I was actually watching something today before it stopped working.
I've already made sure cables are plugged in properly, and displays are mirrored. The cursor is usable-- it can still click on things...I just can't see it.
Specs:
[] Macbook Pro 13" (2012)
[] Running Maverick
[] OS X 10.9.2 (13C64)
[] 2.9 GHz Intel Core i7
[] 8 GB 1600 MHz DDR3
Anyone have any ideas on what's going on?

Update OS X. Version 10.9.3 was released a month ago. Launch the App Store and install any Apple recommended updates.
Graphics support was a key part of that update, though not specifically for your model Mac.

I have a 16GB iPhone 3GS. Tried synching my phone through iTunes (11.0.1 I think... on a 2009 Macbook Pro). Now when I connect to iTunes, it says it does not recognise the content on my phone. Is this because my phone (and laptop) are too old?

I have a 16GB iPhone 3GS. Tried synching my phone through iTunes (11.0.1 I think... on a 2009 Macbook Pro). Now when I connect to iTunes, it says it does not recognise the content on my phone. Is this because my phone (and laptop) are too old?
Also, when I tried to Restore the settings, an Error Message pops up that says " The iPhone software update server could not be contacted. The requested resource was not found.
I'm trying to free up space on my phone by removing [literally] thousands of old photos which were originally synched to the phone, because I had forgotten to uncheck the photos button when I synched it ages ago.
I have also tried synching it on my 24" iMac (running OSX Snow Leopard). But again, when I try restoring the phone through itunes, it says the file is corrupted. It sggests unplugging the device, and then plugging it in again. I have done this numerous times with no success.
I'm guessing it must be because my phone (and versions of iTunes, and OSX) are all too old.
Please can anybody help.

How come my macbook Pro doesn't automatically connect to my wifi when it is saved under known networks?

How come my macbook Pro doesn't automatically connect to my wifi when it is saved under known networks and i have the box checked under network settings?

Random35,
does your wi-fi router filter access by MAC address? If it does, then have you added your MacBook Pro’s MAC address to your router’s whitelist of acceptable MAC addresses?

After many days of frustration, I try a stupid thing.... Put the SD card in the Lock Position and... Voilá!
The way I find to access the content is put the SD card in the Lock position..

Windows laptops can't connect to Macbook Pro shared internet when WEP security is on

As the title states, my Windows laptops can't connect to Macbook Pro shared internet when WEP security is on. My iPhone has no problem asking for the password when I try to access the shared internet my MacBook Pro on Mountain Lion is sending, but my Samsung Slate on Windows 8 sees the network and only succeeds in connecting when no password is required. When security is on, it just tries for a moment and says it can't connect to the network without ever prompting me for the password. The same thing occurs on my Asus Netbook running Windows XP. Since all the reviews about OS X's internet sharing mentions "any wifi device" can access it, I haven't assumed it's only compatible with Apple products. I want my MacBook Pro to save me from needing an external router.

I would post a new question, outline the specific problem you are having and skip all the extra. Outline any steps you have taken already to try and solve the problem. Post the question in the forum most likely to have followers who can answer your question. Give your topic a good title such as: My MacBook Pro cannot connect to my WEP-enabled PC.
Provide any hardware information that may be relevant such as the make and model of your router and method of connection - wired or wireless.
I'm no authority, but have you tried using WPA2/Personal on your PCs? This method is most compatible with Macs.
If the WEP password is a hexadecimal password then on the Mac you need to preceed the number with a $ sign or the hex digits, 0x.

Hi John. Thanks for that input. At Step 6, after clicking "Next" I get a window telling me my OS version is unsupported and the installation may not complete. I am prompted to go to Canon's web site to "Check Latest Info".
I've had this window on previous attempts and from Canon's web site I downloaded two drivers as follows
- ICA Driver V4.0.0
- Canon IJ Network Tool V4.5.0
I'm not sure if these are the correct / complete drivers I need for this install or not.
I continue to follow all the steps. At step 9 I click "Wireless Set Up using USB" amd get a License Agreement (a little different than instructions)
I click "Agree" and it goes to a Setup window with two progress bars showing the installation. I've not been prompted to connect the USB?
After the Setup window is done, I am then prompted to connect the printer via USB. I connect the printer and click on "Redetect". It is not detected.
I then try following the Canon on screen instructions for connecting to the wireless LAN amd enter the password. It searches and indicates "Connecting" on the window, but it never connects and the blue light just blinks
So, at this point I am stuck??
Thanks
Stephen

My MacBook Pro shuts down when i connect a USB cable.

My MacBook Pro shuts down when i connect a USB cable, only when its a 30 pin apple cable. Well one USB shuts it down and the other one doesn't work at all.
it only happens when i use an apple cable. It has no problem with my external drive nor with other things.
Ps. i did use different apple cables and they all shut it down.

What are you connecting? iPad, iPhone, what?
When you say a 30-pin Apple cable do you mean a Lightening to USB cable?
Little more info needed...

MacBook Pro drops Wi-Fi connection after upgrading to 10.6.5. Fixed!

MacBook Pro drops Wi-Fi connection after upgrading to 10.6.5. Airport says no IP is detected then suddenly reconnects?
This has been a problem I’ve been troubleshooting for the last month. I’m new to the Mac family and have loved my experience up until this point. I was under the impression that mac’s are supposed to be so user friendly that even your grandmother could use one with out having any technical knowledge. I mean I shouldn’t have to be deleting drivers or reformat my mac because of an OS update glitch? (That’s what the guy at the Genius Bar told me to do.) What I refused to succumb to was that I’m really good with computers. I get at least a phone call every other week from someone asking me for tech support. So I’d like to think that nothing I’ve done to the system would have caused this anomaly.
After numerous attempts of troubleshooting and researching forms I believe I’ve discovered a solutions that seems to be working for me.
Here are the steps I took to create a consistent connection to my Wi-Fi. I believe it was a combination of all these steps to create success.
1.) Changed my router to use G Wireless Only. (I’m assuming this removed any unnecessary frequencies to allow G to broadcast stronger?)
2.) Did a scan on the other networks in my area to find out what channel everyone else was broadcasting on. Copy and past the text below into a terminal window.
sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resourc es/airport /usr/sbin/airport
This will allow you to simply type “airport” in the terminal window to execute the command.
Type airport –s
This will display all the networks in your area and what channel they are broadcasting on.
3.) Changed my router to use a channel that no one in my area was using. (This helped to make my network stronger and free of interference.)
The last steps will help your home network improve but these next steps I believe helped fix any install errors caused maybe by the 10.6.5 update on my mac.
4.) Boot your Mac into safe mode by holding down the shift key while booting.
5.) Open System Preferences and Click on Network.
6.) Click the drop down menu from Locations at the top of the screen. Click edit locations..
7.) Create a new location by clicking the + and give it a new name.
8.) Delete the old location by clicking on the old locations name and click the – to remove.
9.) Reboot
10.) Open System Preference and click on Network.
11.) Click on the settings sprocket next to the + and – and click on Set Service Order…
12.) Drag Airport to the top of the list of devices then click Ok.
Now this last step is what seemed to eliminate the issue. I hardcoded my IP address to my network. This way my computer will always use the same IP and not have to search.
13.) Click on Advanced under Network.
14.) Click on TCP/IP. Click on the drop down for Configure IPv4 and change it to Manually.
15.) Fill out the fields with your IPv4 Address: 192.168.1.1xx (x=whatever number) Subnet Mask: 255.255.255.0 Router: 192.168.1.1 (All of these settings are pretty standard for most home networks.)
16.) Click on the drop down for Configure IPv6 and change it to Off.
17.) Next click on the DNS tab at the top.
18.) Click the + to add a DNS Record.
To find your DNS Server open a Terminal window by launching Applications --> Utilities --> Terminal
Then Type cat /etc/resolv.conf
(There is a space between cat and /. Without it you’ll get no such file or directory.)
This should return two addresses. Your ISP’s DNS Servers.
19.) Add both records to the DNS and click Ok.
20.) Click Ok then under Network Click Ok.
21.) Reboot router then Mac
22.) Fixed my connection issue
The symptoms I experienced eluded me to believe that something with the DHCP is going into an idle then disconnecting. Before when DHCP was set to automatically assign the network signal would time out then searchers for a new IP resulting in Airport displaying No IP is detected. By setting my IP to a fixed address I still notice a slight drop in bandwidth at moments but because of the assigned IP I never loose connection. I can now stream video, play games, chat all without getting disconnected.
I believe this fix will work for my home network but I also noticed this issue at work so for each location that I connect for the time being I’ll create each there own location and hardcode the IP address to that network. I’ve been reading that 10.6.6 is coming soon so maybe this will be resolved for good in the next update.
Let me know if this helps or if you have any questions.
Best of luck.

I have been having the same issue for the last two weeks. No real indication as to why it ever began other than I had turned off my router and Airport Extreme Base Station off for a weekend while I was away from my place.
iPad, iPhone, iPod Touch, all have no issues at all with my Airport Extreme Base Station. Can stay connected throughout my living room, bathroom, bedroom, no issues whatsoever.
My 5 month old MacBook Pro 2.66 GHz Core i7 Airport is sometimes perfect, able to connect, DHCP, and browse without issue. Then, for no reason, I won't be able to join my wireless network, or when I can join, I can't pick up an IP address. And then it will connect, pick up and IP, and then it won't browse. No real rhyme or reason to when this will happen, or when it works.
I thought that it was an issue with my MacBook Pro, but then my sister visited with her brand new MacBook Pro 2.26 Intel Core 2 Duo, and while a month ago she was able to connect, DHCP, and browse without issue, this weekend she had all of the same issues I was having.
My XBOX 360 and MacBook Pro have absolutely no issues with the wired connection. Only my WAN seems to have this issue.
Did you ever find anything more to this?

How do I stop my MacBook Pro from trying to connect to a home Server?

My Macbook Pro keeps trying to connection to an external harddrive server that I run at home when I am not home. I get an error that the server is not available. I checked the console and it gives an error of AFP_GetServerInfo - can not connect 64. I have removed from my favourite servers connections, I have deleted all programs that start automatically but nothing seems to fix the issue. Anyone have any ideas?
I'm running a 2014 13" Macbook Pro with Yosemite 10.10.3.
Cheers,

There are many possible causes for this issue, and it may be very hard to resolve. Please take whichever of the following steps is applicable that you haven't already tried. Back up all data before making any changes.
If you get the alert in the login screen before you log in, stop here and ask for instructions.
Step 1
If you get the alert as soon as you log in, it's probably caused by one of your login items or by software that otherwise loads at startup or login. Ask if you need help identifying it. Known offenders are "1Password" and "Adobe Resource Synchronizer."
Step 2
If there's an icon representing the server in the sidebar of a Finder window, hold down the command key and drag it out.
Step 3
You may have created aliases to files or folders on the server. If you don't know whether you did that, you can find all aliases as follows.
Triple-click anywhere in the line of text below on this page to select it:
kMDItemContentType=com.apple.alias-file
Copy the selected text to the Clipboard by pressing the key combination command-C.
In the Finder, press command-F to open a search window, or select
          File ▹ Find
from the menu bar. In the search window, select
          Search: This Mac
from the row of tokens below the toolbar. Below that is a popup menu of search criteria, initially showing Kind. From that menu, select
          Other...
A sheet will drop down. In that sheet, select
          Raw Query
as the criterion, then click OK or press return.
Now there will be a text box to the right of the menu of search criteria. That's where you enter the raw search query. Click in that box and paste the text you copied earlier by pressing command-V.
The search window will now show all aliases on mounted volumes. You can see the target of each alias by selecting it and opening the Info window. Delete any that refer to the server.
Step 4
Open the Printers & Scanners pane in System Preferences and delete any network devices you no longer use. If in doubt, delete them all and add back the ones you want.
Step 5
Copy the line below to the Clipboard as in Step 3:
~/Library/PDF Services
In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens. You won't see what you pasted because a line break is included. Press return. A folder may open. If it does, move the contents to the Desktop, or to a new folder on the Desktop. Log out and log back in. Test. If there's no change, put the items you moved back where they were and continue.
Step 6
Open the folder
~/Library/Preferences
as in Step 5 and move the file named "loginwindow.plist" items in that folder to the Trash, if it exists (it may not.)
Log out and back in again, and test.
Step 7
Other possible causes are references in the iPhoto, iTunes, or iMovie library pointing to the server, bookmarks in the Preview application, and PDF files created by Adobe Acrobat with embedded scripts.
Try rebuilding the iPhoto library, if applicable.
If you get the alert when connecting an iOS device with iTunes, re-create your iTunes library and playlists. See also this discussion.
Step 8
Resources such as images or sounds stored on the server may have been added to various applications. Examples would be pictures added to Contacts and custom sounds added to Mail. The range of possibilites here is practically infinite, so I can't be more specific. You might get a hint by launching the Console application and looking for error messages that appear at the same time as the alerts.
Step 9
Disconnect all wired peripherals except those needed to start up. Start up in safe mode. Test. After testing, restart as usual (not in safe mode) and verify that you still have the problem.
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 Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Step 10
Launch the Directory Utility application. Depending on what version of OS X you have, you may be able to do that by entering the first few letters of its name in a Spotlight search. If that doesn't work, triple-click anywhere in the line of text below on this page to select it:
/System/Library/CoreServices
Right-click or control-click the selected text and select
          Services ▹ Open
from the contextual menu.* A folder named "CoreServices" will open. The Directory Utility application is in that folder, or in a subfolder named "Applications".
In the Directory Utility window, select the Directory Editor tool in the toolbar. Select Mounts from the Viewing menu in the toolbar, and /Local/Default from the node menu, if not already selected. On the right is a list of names and values. By default, the list is empty. If it's not empty, post a screenshot of the window and stop here.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). Open a TextEdit window and paste into it (command-V). Select the line you just pasted and continue as above.
Step 11
Open the following file as you did in the last step:
/etc/auto_master
It will open in a TextEdit window. The contents should be exactly this:
# Automounter master map
+auto_master          # Use directory service
/net               -hosts          -nobrowse,hidefromfinder,nosuid
/home               auto_home     -nobrowse,hidefromfinder
/Network/Servers     -fstab
/-               -static
If there are any other lines in the window, post them. Otherwise, close the window.

MacBook Pro can't actually connect to Wi-Fi with Self-Assigned IP

Hi there
I have a 15 inch MacBook Pro and it can connect to Wi-Fi but have no actual data coming in. And it says self-assigned IP.
This only happens to my home Wi-Fi, however, I can connect and use Wi-fi at school or anywhere else perfectly. In the mean time, my Android phone and my flatmates' Windows have no problem using the Wi-Fi. The problem has been going on and off for a month, sometimes it works again and sometimes it goes wrong like this again.
During this time I mostly use my other MacBook Pro 13 inch Retina. Until today, this problem happens on my 13 Retina mac for the first time, and the 15 Pro again as well. A few days ago, my 15 Pro started working again, and today they just gone wrong together at the same time.
I just found out that my 15 pro can still work if connected to ethernet, but I can't just work in the living room, where the router is. And as you know Retina doesn't support Ethernet.
I've check on the Internet and found many people have the same problem as I do. I also tried lots of ways to fix it with the information I found online. And nothing works. I even suspect that it's actually my flatmate blocks me out with some setting on the router (Is it possible?)
Anyways, can someone please help me fix it thoroughly... Please and thanks.

Each country regulates wireless networking differently. Wi-Fi devices are restricted to certain frequencies and power levels. The client devices try to find out where they are and configure themselves accordingly. Since a wireless access point (WAP) usually does not move across national boundaries, the Wi-Fi regulatory domain (country code) is set by querying the first one to respond when the client initializes itself. You don't have any direct control over it on the client. If your device is picking up the wrong country code, and is therefore locked out of using some Wi-Fi channels or operating at full power, the only lasting solution is to fix or remove the misconfigured WAP.
To find out which WAP's are broadcasting a wrong country code, do as follows.
Triple-click anywhere in the line below on this page to select it:
/S*/*/P*/*/*/*/*/airport -s | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in 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.
Paste into the Terminal window by pressing command-V.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign ($) to appear.
A TextEdit window will open with the output of the command. The first line should look like this:
SSID BSSID RSSI CHANNEL HT CC SECURITY (auth/unicast/group)
Each line below that one represents a WAP within range. Compare the two-letter code in the column headed "CC" with the ISO code for your country. The code "X0" means that the country couldn't be determined. If a WAP with a wrong code is not under your control, try restarting the computer as close as possible to your own router.

Macbook Pro suddenly will not connect to the internet via ethernet cable.

I know this is a long shot... but I figured I would give it a try.
My macbook pro suddenly does not connect to the internet via ethernet cable. Please bear with me, as I am not very tech-savvy - I will try my best to describe the symptoms!
I connect to the internet via ethernet (we don't have wifi). It was working before I went to work, and when I came home I suddenly couldn't get anything to work (I know everyone says this, but I truly didn't mess with anything). Internet browsers just think for awhile and then turn up the 'You are not connected to the internet' error.
I went into my network preferences and curiously, the 'Ethernet' shows a green dot and says 'connected'. However it says 'Authentication server is not responding' underneath the last part that says '802.1X: WPA: eduroam' (I think that is my user profile).
When I go into my 'security' settings I can see that my firewall is off, so that shouldn't be causing any problems.
I've tried restarting the router and computer itself many times. Diagnostics just gets to a certain point and reports back 'Network Diagnostics cannot fix the current networking problems.' I've also tried switching to a different ethernet cable, and I tried both cables out on a PC laptop and it connected without issue. Additionally, I brought my macbook along to a friend's house and it connected to his wifi just fine, so the problem appears to just be with ethernet connections.
I know it's hard to troubleshoot this kind of thing without being there and having a look at the computer yourself, but any tips wouild be greatly appreciated.

As I mentioned above, I am not very tech savvy so I have no idea why a wireless protocol would be showing up there, I'm just listing everything I see in hopes that someone might know something I can try. This is why I am asking for help here - I'm not sure what has happened that has made me unable to connect, especially since it seemingly occured while nobody was using the computer.
I guess I should clarify that I'm not a total hillbilly- normally my firewall is set to 'on', but I set it to 'off' to try and troubleshoot the issues here as I was told that sometimes it can interfere with the computer's ability to connect to the internet. If this is not the case and firewall does not affect anything, I will turn it back on while I try to fix this.
I have tried the method you mentioned above a few times - I actually contacted my ISP earlier this week and they recommended resetting the router like that. They didn't mention any known network issues.
