I cannot connect my MacBook to LG Smart TV

I cannot connect my MacBook (13-inch Late 2007) to LG Smart TV (47LB730V) via "mini-DVI to HDMI" cable.
TV says that something is connected to HDMI input and then show "No Signal" message.
But when I connect my Mac with the same cable and settings to another display (to DVI or HDMI input) everything works fine.
I think I should place something to "system\libraries\displays\overrides" folder, but do not know what

HT1338 cannot connect my MacBook Air to a projector -does not detect and 2nd monitor. I have a new Mini port to VGA cable made by apple. When I read online I see that many people have the same problem - Is this an Apple defect??????????????????

I cannot connect my MacBook Air to a projector - It will not detect a 2nd monitor or display. I am using an Apple made Mini Display port to VGA adapter. As I read online I see that many other peple are having the same problem. Is this an Apple defect!!???? If so it just burst the bubble about how great macs are. I never had a problem with that on a PC. I hope I am wrong. What can you tell me?

Hi There,
I have had the exact same issue but with a projector.
The issue lies with Mountian Lion 10.8.2.
I tried many a combination with no luck to get HDMI working.
Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
Bought my macbook home and voila, now displaying through my projector.
There is a small graphics update after 10.8.1 which seems to be the cause.
Hope this helps.
Thanks.

Cannot connect 2 macbooks to the internet through AEBS?

Hi,
I have 2 Macbooks, Airport Extreme Base Station & a 320T D-link router. My ISP is plusnet who uses PPPoA settings on the d-link router. So i have set the router up and when i connect it to the Macbooks directly via ethernet i can access the internet. But once i connect the d-link router to my AEBS i cannot connect to the internet? Both Macbooks can see the base station but they cannot access the basestation. If i put the base station in bridge mode the light will go green and one can connect to the internet but obviously i want both to connect! I am unable to put the d-link router in bridge mode as my ISP does not support this as the router will only work on the PPPoA settings to retrieve the IP's etc from Plusnet. I have spent countless hours on the phone to apple and changing settings but to no success. I have spent more money to buy the d-link router as i had a netgear D111MP router previously but i read that it was a poor product to go with the AEBS. So the issue does not lie with the router?
If anyone can help i would appreciate it so much as this has become so frustrating!
Many thanks!!

Thanks Duanne, problem is that i have bought the netgear DM111P and the d-link 320T and found out that they cannot work for some reason. So i have spent £70 on both modems/routers plus the £119 on the AEBS. It's just a bit annoying when i have spent a lot of time and money on something which i was hoping would be as simple to set up as all the other apple products.
By the way i'm not having a go even though it sounds like it! The main thing on my mind is to get my AEBS working. Would it be possible to advise me on a router that will work well with my AEBS to solve this issue i am having? Also one that can use the PPPoA settings from my ISP? This would be greatly appreciated as i don't want to go out and buy another router and find out it doesn't work.
Also if i get a router that can do this what would be the setup of my AEBS?
Thank you for your time on this!

HT1349 Why bluetooth cannot connect between MacBook Pro and iPhone 3? If I need how?

I'm trying to connect ipnone 3 and MACBook Pro through bluetooth for photo transfer...but unable to recongnise, please advise?

"I tried enabling Bluetooth on my MacBook Pro and iPhone, thinking I could file transfer some photographs."
This is not a feature of iphone. Never has been.
Other than tethering for internet, where provided by the carrier, you cannot connect to a computer/device/phone and do anything.
Bluetooth is for handsfree telephone devices/headsets, stereo speakers/headsets, some keyboards, some peer to peer apps from the app store and tethering where provided by the carrier.

HT204291 Cannot connect my MacBook Pro to Airplay.

Trying to connect my MacBook Pro to Airplay. I get the icon and menu for selecting Airplay but it is grayed out and cannot be selected. I have IOS 10.8.2. Anyone experience this?

Remove the security and see if you can connect. It may be the type of security (WPA, WEP, etc.) that your Mac isn't liking.

Cannot Connect My Macbook 2011 to TV with Thunderbolt

I am trying to connect my Macbook Pro to my TV through my thunderbolt. For some reason it says that my thunderbolt is inactive and I keep receiving this message, "None of the member interfaces are connected. Click Advanced for details." I then go to my advanced details and see that my Thunderbolt 1 is Inactive. What do I do?

Hi s,
I don't think a basic adapter is going to do it, I think you need a transcoder such as something like this: http://www.digitalconnection.com/products/video/9a60.asp

IPad cannot connect to MacBook Pro

I have recently updated to Yosemite on my MacBook Pro and my iPad is running iOS 8.1.
If I plug the iPad into the MacBook (usb) then the charge symbol on the iPad flashes rapidly and repeatedly between charging and not charging. When I open Itunes I get an error message saying "iTunes could not connect to this iPhone. This device is no longer connected." which I then can't get out of - i.e. I click OK on the error message and it returns straight away.
Anyone got any ideas as I now cannot sync or backup my iPad?
MacBook Pro (Retina, 13-inch, Mid 2014)
2.8 GHz Intel Core i5
8 GB 1600 MHz DDR3
iPad Model MC705B/A
16GB

Sorted - kind of - not my cable but it is the socket on the iPad itself. OK if just plugged into a charger, but when connecting to a Mac, it's obviously doggy as it works if I apply pressure to one side of the plug. As soon as I release the pressure it starts flickering on the power indicator again and the error pops back up.
So physical problem, not Yosemite or iOS8

HT3669 Where did you get the driver information for the HP 4MV. I cannot connect to MacBook Pro on 10.6.8 and believe you have information that might help. Please advise ASAP.

Apple published a report - http://support.apple.com/kb/ht3669#HP - that states system 10.6.8 supports the HP LaserJet 4MV. If this is accurate information, I would like to know where the drivers are located. I have spent more than three hours with your technical support and no one has a clue how to make this combination work. Please help ASAP. Thanks!

Welcome to Apple Support Communities.
We are all users here. There is no one from Apple responding on these user forums.
You did not mention which interface you are trying to use, or what steps Apple support had you try already, so I'll start with basics.
Your mid-2009 MacBook Pro would have shipped with OS X 10.5 'Leopard', and OS X 10.5 and prior versions supported the AppleTalk network connection and protocols, as well as others.
OS X 10.6, 'Snow Leopard' dropped support for AppleTalk.
So, Snow Leopard 10.6.8 likely does contain the correct DRIVER for your printer, BUT if your printer was originally connected via AppleTalk, AppleTalk will not work with Snow Leopard. Period.
There is at least one recently-published workaround to connect your printer via Ethernet, provided that you have the OPTIONAL HP Ethernet MIO interface card installed in your HP LaserJet 4MV printer.
If your printer DOES have the optional Ethernet interface, you can reconfigure your printer to use Ethernet instead of Appletalk. No, it's not 'plug and play' like AppleTalk was, but patiently following detailed step-by-step instructions it can be made to work.
The HP forums contains brief instructions on how to configure MIO Ethernet, and once configured, how to select the 4MV driver within this thread:
http://h30434.www3.hp.com/t5/Mac-Printing-and-Scanning/Laserjet-4mv/td-p/1176843
This Macrumors forum thread contains a post by TrumpSAJ with more detailed configuration instructions:
http://forums.macrumors.com/showthread.php?p=8748935#post8748935
Other World Computing has an older guide linked here:
http://blog.macsales.com/1897-appletalk-not-available-in-snow-leopard
And a thread on Gigaom discussing some other alternatives to Ethernet (for a variety of printers):
http://gigaom.com/apple/how-to-resurrect-your-appletalk-printer-in-snow-leopard/
In my opinion, if you don't already have an HP Ethernet MIO card installed in your circa 1995 printer, then it's time to buy a new printer. Spending more money to 'upgrade' something that old doesn't seem like a good investment.

Cannot connect my Macbook air to my Airport Express

Unable to get my new Macbook Air to connect tmy existing wifi that uses Airport Express. It just timesout after about 5 seconds. My mew iphone connected straight away.

connect is in the eye of the beholder
connect can be the appletv being able to access the shared itunes lib of the macbook air if the macbook air's firewall is set to allow it and if itunes on the macbook air is set to share the itunes lib at all
connect can be the macbook air being able to use airplay to play music out of the appletv's speakers as one would an airplay express
or airplay mirror which mean displaying the macbook air's screen on the tv using appletv
if the device is supported in that way you can read here

Imac cannot connect with macbook pro

I'm using an Airport express as my router and I cannot get access to files on the other computer. When the Apple Extreme worked, this was not a problem. I have files sharing checked in the Sharing Preferences and Wireless is the number 1 in the networking screen. I can print wirelessly. Please help.

We did that, but it just doesn't seem to be able to connect. So basically we tried to connect to our network and insert the password, but afterwards it does nothing. Weird thing is also that the network symbol (top right of the screen) says that it has been connected, but when I go look at the system preferences --> network, it states that it has not been connected

Cannot connect my MacBook but every other device will

my MacBook pro, iPhones, iPad, iPod all connect but it says I have the wrong password which is not possible since all the others are connecting now.
Any ideas? I have restarted both devices twice. It all started after I connected a ATT Microcell.

When it tells you that you have the wrong password, do you at least get prompted anywhere to type it in manually?
Try to delete it from the keychain.

Re: I cannot connect my PC to my Smart TV

Hi,
I currently have a problem connecting my Medion PC to my Toshiba TV.
My PC doesnt have a HDMI Cable but does have a VGA Cable, and my TV doesnt have a VGA Cable.
Which cables would I need to have to enable me to be able to connect my PC to my TV,
With thanks,
Chris

Have both devices S-Video port? I dont know which PC do you have exactly but check which ports have both devices. It must work somehow.
