My Macbook pro 13" won't connect to my samsung monitor?

After updating my mid 2012 13" macbook pro to OSX 10.9.4 it is no longer recognized by monitors. I have tried using both a thunderbolt to hdmi and thunderbolt to VGA and tried used cables which I know work. Any help would be extremely helpful.

Nevermind, I just fixed it by disconnecting the modem, router and airport for several minutes, and then plugging them back in, modem first, then router, then airport. Seems something needed to be reset.

My new macbook pro retina won't connect to my iPhone 4s via bluetooth

Just bought macbook pro retina. have had iPhone 4s for two years and use it to tether my iPad to regularly no problem. however the macbook pro won't connect to the iPhone via bluetooth. it recognises it's there and a connection code is displayed, but when I enter the code it won't connect and the phone insists that I agree to 'forget this device'. how do I enable tethering so I can use the 3g signal to browse on my laptop whilst travelling please?

Only thing I could suggest would be to "Reset Network Settings" on the phone (Settings> General> Reset>) . Of course, this will forget and delete any saved Wi-Fi or network configurations, but if that's not a problem for you then, maybe worth a shot.
Although saying that, I think iCloud remembers old settings (if you are connected and sharing network configurations), so may not be a total loss.

MacBook Pro Bluetooth won't connect with iPhone4s

I am trying to connect my iPhone 4s bluetooth with my Macbook pro, but it won't let me connect . Sometimes it would say "Andrew's Mac Book is not a supported device" or "Make sure 'Andrew's Mac Book Pro' is turned on and in range" (My macbook is right next to my phone and its on. Why won't it connect?

You can't connect to your Mac to transfer data via Bluetooth. You can connect your Mac using the Hotspot feature to access the Internet via the iPhone.

Macbook Pro/iTunes won't connect to Airplay ATV

Hey guys,
I have a bit of a weird problem here and can't figure out what the issue can be. I have an Apple TV (2nd Generation) and a Macbook Pro (Early 2008) that won't connect through Airplay. I can see the ATV in my Airplay/speakers options but when I select it it just gives a prompt that says "Connecting to Apple TV" for about 2 minutes. After that the message disappears and I find my iTunes is still not connected to ATV.
Now here's the odd part... ATV can play my library through Home Sharing just fine. My iPhone 4, as well as my wife's Macbook (white 2008) both connect fine through Airplay too.
The only thing that has recently changed in my setup is a new router (Sitecom WLR-4000). I've tried rebooting that, also tried turning off IPv6 on my MBP but both didn't change a thing.
Anybody have a possible solution??

It seems like I have located the issue. I went on the Macbook and checked the IPv6 settings (in Lion) and for some reason these said 'off', an option that Lion typically doesn't give. After turning IPv6 on, the Airplay didn't connect on this computer either. Upon trying to turn it off, the 'off' option had disappeared.
Then I found a discussion elsewhere on this forum detailing how to manually turn off IPv6 completely within Lion and it did the trick. Both for the Macbook Pro and Macbook.
Hopefully that was it. It's still odd as I'm still wondering what exactly in the router is blocking it from working, so if someone on here has an idea that's more than welcome.
Here's the explanation to turning off IPv6 for whoever needs it:

My new macBook Pro Retina won't connect to my wifi. Password IS CORRECT.

I just got a new-in-box retina MacBook Pro. It sees my wifi network--signal is max--but the base station will not accept the 100% correct password. Other devices have no trouble connecting.
I'm setting it up for a PC switcher. What an embarrassment!
We're trying to connect to a Time Capsule base station which I added to my system last week. No other devices have trouble connecting.
Suggestions?

Macbook Pro Airport Won't Connect When Macbook Pro Bootcamp Will

I have a Macbook Pro 2.16GHz Core Duo that has had problems with Airport connectivity since I got it. I can never get anyone to help me with it because it will never show the problem at the Apple Store.
One place that I have to work at has been very, very frustrating.
They have a number of access points called Wireless #1, Wireless #2, and so on. Every access point is a Linksys-Cisco WAP54GP. All of them are on channel 6. They are using a WEP 40-bit hex key with the same key on every AP. They don't understand the obvious flaws in their system, they will not change it nor help me...at all, so there's no point in suggesting things along that route.
I know that their network and their key works, though, because if I reboot into Windows on the SAME machine it works fine and the connection is great. Mac OS, however, will not connect and will not tell me why. All it will say is "There was an error joining the network." I have read suggestions saying that you have to put a $ or "0x" in front of the key to signify that it is a hex key (which I don't have to use on other WEP hex key networks), but when I try to type that in, the password dialog will not allow the characters $ or "x" and it beeps at me.
Does anyone have any help for me?

It will connect to other networks with and without
WEP. It will connect to other networks that use
WPA.
There are many networks, though, that give me the
"There was an error joining the network.", and I
don't know why.
I cannot enter a $. As I stated previously, the Join
Network dialog will not allow me to enter that
character when it is set to WEP 40/128 bit hex.
Also, as I have already said, I cannot change the
network to WPA. I understand the benefits of WPA
over WEP, but I am not the network administrator.
They will NOT change their settings. I know the
network works with Windows on my computer. What is
it about Mac OS that is preventing this?
Prior to the last Security Update, I believe 2007-02, broke access to 2wire Routers. It was very frustrating to me as well. The fault or problem, I believe, may lie in a firmware update to these routers. I performed one for my 2wire router and I am now able to connect.
My theory...

MacBook Pro 10.8.2 stopped detecting external Samsung monitor

Hello,
My MacBook Pro stopped recognizing my extenal monitor that I use as an extended desktop. I plugged the same monitor into my old machine and it worked fine so I know it's not the monitor. I reset the PRAM and ran disk utilities to repair disk permissions and that didn't help. I have tried every combination of plugging and unplugging the devices I can think of. I am pretty sure the cause if this is a system software update and not the hardware.
Any suggestions?
Thank you!

Crap, same thing here, I used to be able to connect my MBP Late 2008 to Philips hdtv with no problem using Snow Leopard, but as soon as I upgraded to Lion it wouldn't work. I was waiting for Mountain Lion to come out and upgraded hoping for the feature to work again but no success. Money spent on cables are being wasted. Any fix soon to sort it out?

I have a 2009 MacBook Pro that won't connect to the Internet at my university while everyone is able to. How do I fix this?

My roommate has the same laptop as me and she connected perfect fine. I also was here last semester and I could connect with no problems at all. I came back to school this semester and suddenly I keep getting the exclamation mark saying I'm not connected. I'm also connected to the Internet on my iPad right now so I know it works. How do I fix this? Please help!

Try the basics first:
Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

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?

My HP OfficeJet Pro 8600 won't connect to my wireless router

This is bizarre. I have had my HP OfficeJet Pro 8600 for about 6 months. It has generally worked fine, and we have used it wirelessly only. But now it refuses to connect to the router. It can FIND the router, and it can find other networks in the area, but it won't connect to the router. I ran the Wireless Network Test, and the results say:
Wireless On - Pass // Wireless Working - Pass //
Network Name (SSID) found - Pass // Wireless Networks Detected - 9
Printer Settings Consistent with Wireless Router Settings - Pass / No Filtering - FAIL //
So it recommends solution as follows: "1 If MAC Address filtering is enabled, and you would like to keep it enabled, you must add the Mac address of your printer to the list of permitted devices for your router before continuing."
Except, guess what, I don't have MAC Address filtering enabled. I wouldn't know how to do that, much less check for it.
Also, before today, this was never a problem. HELP!
Thanks....
If you are interested, here's more detail and background.
Before today, the only problem we have had is that frequently our Apple laptop (OS X 10.6) has trouble connecting to the printer. This has been odd because the printer is connected to the network, and so is the laptop, but the laptop can't find the printer - it thinks the printer is "offline" (even though it's not). Usually, if I wait a while, it will find the printer, and it will resolve itself work fine. If not, we sometimes have found that it can fix itself if you restart the laptop -- restarting the printer does not make a difference. In fact, I did exactly that today, and it resolved itself. And I printed. Fine, right?
But then I wanted to do more printing, and the problem of the laptop not finding the printer came up again, so I decided to really "get to the bottom of this." I don't remember exactly what I did, but somehow I was persuaded by the online help, that the correct solution would be to go into my System Preferences / Print and Fax, and click on the "-", which de-installs the printer, with the idea of re-installing the printer. But then when I tried to re-install the printer, it could not find the printer. Ugh! Wierdly, it found an 8600 Scanner, but not an 8600 printers. After installing and de-installing the 8600 scanner a few times, I eventually deinstalled everything, and I decided to start from scratch. I got my HP disk, and installed all the software again from the beginning (even though it was already there), and then it looked for my printer, but couldn't find it. So then I got a USB cord, and plugged that in.
So, now I have a situation where I do have a working printer via the USB cord, but no wireless connection at all. In particular, since the Office Jet Pro 8600 won't connect to the router, I don't know what else to do. My Apple MacBook pro is 2 feet away from the printer, and it is connected to the router just fine (as is my blackberry), and I have never before had a problem connecting to the wireless router by the printer.
Any suggestions?

There are two things that can trip the mac filtering test to fail: actual MAC address filtering setup (sounds like this is not the case) and using wireless channel 6 or automatic for wireless channel in the wireless network settings (in the router). Since it does show failed for MAC filtering and you do not use this option, try changing the wireless channel in the router to 1 or 11. Those two channels provide the best compatibility with printers due to less interference. Almost everything defaults to auto or 6 for the channel and this causes a lot of interference. This change should not affect anything at all. To do this, you may need to contact the router manufacturer as the process differs from router to router.
What brand and model is the router?
Has anything in the network settings changed at all?
What version is the Mac OS X? There may be additional steps to take as it sounds like there are two separate issues involved and this could be revisited later.

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.

My MacBook Pro 13" won't turn on 90% of the time I try to get it running, and when it does turn on, even on a charger, it shuts down if I stop using it for 2 seconds and it won't turn back on. Should I replace the battery?

My MacBook Pro 13" won't turn on 90% of the time I try to get it running, and when it does turn on, even on a charger, it shuts down if I stop using it for 2+ seconds and it won't turn back on. Should I replace the battery? It doesn't hold a charge either...

EmadJamal,
the battery won’t melt because of long connection to the AC charger, although that has the potential of reducing the battery’s life.
Do you have access to a second 60 W AC charger to test with your MacBook Pro, or access to a second 13-inch MacBook Pro against which your AC charger could be tested?
