My Macbook Pro will no longer connect to my tv via HDMI

Well basically it is in the title, my Macbook Pro will no longer connect to my tv via HDMI.
I have been using this cable for a long time and works perfectly.
earlier today i used it to connect my mac up to my parents 4k tv, it worked fine, did what i wanted to do.
but now when I've come to connect it up to my tv it recognises there is something connected but it won't display anything
it just says no signal on my tv
im not sure whether my mac has changed some settings on its own to run on 4k but now to high to run on my 1080p tv
pretty annoying so any ideas id be very grateful.
I've already tried
restarting my mac
turning tv on and off
different hdmi ports
thank you

After I installed Lion, my MacBook Pro can no longer detect my external hard drives or my USB flash drives. What should I do?

MacBook Pro will no longer access the internet

We have two macs: A MacBook Pro (2.53 GHz Intel Core Due) and a MacBook (2.4 GHz Intel Core 2 Duo). Both are running Snow Leopard 10.6.8.
Problem: the MacBook Pro will no longer connect to the internet. Network Diagnostics thinks that it is connected. I can use Network Utilitities to ping a site. But Apple Mail, iCal, Safari, Firefox, Chrome, Skype, Software Update, etc., cannot access the internet.
The MacBook Pro is set up with a single user account.
Our internet is provided through a mobile phone provider. If I set up our smart phone to serve as a wireless hotspot, the MacBook, iPod Touch, iPad will all connect. The MacBook Pro will not. If I put the SIM card in a USB modem and connect the modem to the MacBook Pro, the modem software will connect to the internet. If I turn on Internet Sharing on the MacBook Pro, the MacBook, etc., will connect through the MacBook Pro, but the MacBook Pro itself will not.
So to sum up: the modem software connects to the internet, Internet Sharing works as it should, Network Diagnostics and Network Utilities can't see a problem, and yet none of the apps that NEED to access the internet are able to.

I have tried going to System Preferences / Network and deleting Airport and then adding it back. I've tried disabling the Firewall. And the same with reboots after each.
We're from the States but currently our work has us in Africa. To keep from inadvertantly passing on windows viruses to others (viruses are rampant in Africa), I'm running the Intego anti-virus software on both machines (VirusBarrier X6). I mention this because the problem started after rebooting after an update for that software. (The MacBook Pro has had the update, the MacBook has not.) But I also used Time Machine in an attempt to roll back VirusBarrier X6 to its pre-update status. That didn't solve the problem either, which makes be think that the Intego problem didn't cause the problem. But I mention it to be thorough.
There is an Apple-certified service centre in country, but it's a long drive away that I'd rather not have to make. As it would for any of you in this day and age, this is really hampering my work. Any and all help is much appreciated.

THE FIX
After hours (days actually) troubleshoorting, involving 4 people and Apple Support folks, I'll save you time. If you have VirusBarrier-follow the Manual to uninstall. use Intego's uninstall and deauthorize Virusbarrier before you trash it. If you have Net Nanny, trash it.
None of the above-it is Foxcomm's Airport/Bluetooth (661-5867) card. Faulty, non existent, blown a transistor, are all comments from Techn Support reps (the Genuis blue shirt reps)
Take it into an Apple Store, have them check the Airport card (and only the airport card) using " a different operating system". Sorry that is a black hole, as the machine disappeared to the back of the store for"testing. Don't re-install the OS, delete plist files or applications, reconf and spend hours wasting your time.
Virusbarrier, net nanny or a faulty Airport card. In warranty it is covered; out of warranty:70.55 plus $39 to have Apple officially loosen the screws.I have a late 2011 MacBook Pro, can't speak for older models.
Hope this helps the community.

Macbook pro will no longer boot from main sata bay after Yosemite

Hi!
I am really stuck as to why my macbook pro will no boot from the main Sata bay.
I have the macbook pro late 2011 - a few months ago I installed a samsung 840 evo, and moved the 500gb hdd into the optical bay and all has been working perfectly until last night.
I installed yosemite two days ago and it worked perfectly to begin with... then when I re opened my laptop everything was frozen. I restarted it and it wouldnt get past the grey screen. Then I managed to get it to the internet recovery stage....however it would not recognise the SSD, so I had to install Lion on the HDD.
After I logged on it gave me the message saying that the disc is not readable and on disk utility I can only see the "samsung ssd" but no details about it.
I thought that the SSD may have gone, but when i removed it and plugged it in via USB I was able to boot from it with no issues.
Does anyone know if this has anything to do with the new OS? or whether it is the Sata cable?
Thanks for any help!!!

Hi, I have been having the exact same problem with a late 2011 MBP 15 inch. I replaced the hard drive with a samsung SSD 1.5 years ago, along with a samsung SSD in the optical drive. It worked great until the Yosemite upgrade. The MBP seemed to work reasonably well for a few days after the upgrade, but then it started stalling on various programs (spinning beach ball on Mail, Safari, etc). Start-ups were also longer and had a loading bar each time, which was new since the upgrade. I left the MBP to sleep last night and when opening it, it crashed and tried to restart. On restart it loads to the login screen, then after I enter the password it partially loads (based on the loading bar), then shuts off. I removed the SSD and plugged it in with a USG, but that didn't change anything. Here is a picture after using CMD-V before it shuts off.

MacBook Pro will no longer recognize new SSD via USB

I just received a brand-new 512 GB Samsung 840 Pro SSD from Newegg this morning.
I own a 15-inch MacBook Pro (Mid-2012) with 16 GB of RAM and a 2.3 GHz Core i7 running Mavericks (10.9.1).
Earlier today, I plugged in the SSD via a third-party USB-to-SATA adapter that I also purchased from Newegg at about the same time. The machine recognized the new drive, and I opened up Disk Utility to format the drive as Mac OS Extended (Journaled).
Once that finished, I used Carbon Copy Cloner to clone my existing HDD to the SSD. Before it began, the program asked me to create the Recovery HD, so I enabled that option. The rest of the process proceeded smoothly. I quit CCC, ejected the drive, and put it away for the rest of the workday.
When I arrived home tonight, I plugged the SSD back into the Mac in hopes of test-booting it externally. Unfortunately, the machine will no longer recognize that anything is plugged into the Mac. I find it highly unlikely that the USB adapter could be malfunctioning; I unboxed it this morning and it's been mere hours since the successful clone attempt. I also find it hard to believe that the SSD could be broken, either.
I tried to disable rEFIt and manually invoke the boot selection screen, but even when that happens, the drive fails to mount. For the same reason, I can't erase the drive to start over, either. I've tried both USB ports, as well as rebooting with the SSD connected and unconnected.
My research tells me that people often have problems trying to get SSDs to boot when they've been installed in the drive bay, but nothing I've seen suggests anyone's had a problem booting from the external SSD after a successful clone attempt. What am I missing?

I'd start by resetting the SMC. Follow the method for "a battery you should not remove yourself."
http://support.apple.com/kb/ht3964
I have no experience with Samsung SSD's, but I've read a number of posts here of people having problems with some of them. That could be a possibility.
The other thing you could try at this point is to swap the drives. If it's cloned already and the drive is good, it should boot. That would indicate the enclosure failed after the copy.

10.6.4 Macbook Pro will no longer connect to Apple bluetooth keyboard/mouse

I installed the 10.6.4 update and my MacBook Pro 17" froze after a while. I rebooted and now the bluetooth will not connect or my Apple wireless keyboard or Mighty Mouse. I can also no longer turn the bluetooth off.
Anyone else having problems?

Same thing happened to me. I had the same problem updating from 10.6.2 to 10.6.3 also.
I was able to fix it again (in the update from 10.6.3 to 10.6.4) using the same approach:
Look in both /Library/Preferences (the library folder at the root level of your hard drive) and ~/Library/Preferences (the library folder inside your user folder). Delete the file com.apple.Bluetooth.plist from both locations then shut down the computer fully before restarting.
It is important to click shut down (and not just restart). I don't know why, but it won't work if you just click restart.

My one year old macbook pro will no longer play DVD's.. why?

After a year, without any problems playing DVD's, my macbook pro has suddenly decided that it no longer wishes to have anything to do with DVD's and spits them out at the first opportunity. Can anyone out there help to rebuild this once loving relationship.

SuperDrives can fail and you don't have many options in replacing them. You can get Apple to replace it or travel over to OWC - here - and look at the options for replacing the SuperDrive yourself.
Before doing anything, however, I'd take your computer into your local Apple Store and have them diagnose the problem. That won't cost you a thing. If you're still under AppleCare warranty, they should replace the drive for nothing. If you're not under warranty go in knowledgeable, at least, at what it would cost you to replace your SuperDrive yourself - and then find out what Apple would charge.
Good luck - it just sounds as if you SuperDrive has bitten the dust...

My MacBook pro will no longer connect to a wireless network that I've been connecting to automatically for months and I'm not given the opportunity to re-enter the password.

I am trying to connect to a wireless network that I have connect to automatically for over a year. When I try to connect I simply get the following message: "the wifi network xxxx could not be joined". I have moved closer to the router as suggested and I have attempted to run diagnostics without luck, I have rebooted, I have toggled the wifi on and off. I'm at a loss now...
My MacBook Pro system is running OSX 10.9.5, 2.9 GHz Intel Core 17 processor, 8GB 16000MHz DDR3 memory.

My old Macbook Pro will no longer turn on (black screen)....

..... but I finnally got an external harddrive to transfer my music and photos to my new Macbook Pro yesterday. Great timing. Is there a way to transfer files to the external harddrive even though my computer wont start?

here's what you can do,
you can take out the hard drive in your old mb and put it in your external enclosure.
once that's done, you can transfer all the files you need from your old hard drive.

ICal on MacBook Pro will not receive dates from iPhone, but iPhone will receive dates from iCal on MacBook

I recently got a MacBook Pro after having an iPhone and iPad since last year. I have iCloud set up on all devices to share calendar dates. However, when I input an event on iCal on the MacBook everything is fine and the event shows up on my iPhone and iPad calendars, but when I input an appointment on my iPhone, it will not update to the iCal on MacBook.
Help please?

First check that all your settings are correct, that calendar syncing is checked on all devices (system preferences > iCloud on a mac and settings > iCloud on a iPhone, iPad or iPod).
Make sure the calendars you are using are in your 'iCloud' account and not an 'On My Mac', 'On My Phone' or other non iCloud account (you can do this by clicking/tapping the calendar button in the top left corner of the application ), non iCloud calendars will not sync.
If you are sure that everything is set up correctly and your calendars are in the iCloud account, you might try unchecking calendar syncing in the iCloud settings, restarting your device and then re-enabling calendar syncing settings.

My 13in Macbook Pro can't see a wireless network but my friends Macbook Pro can

Me and my friend both have identical 13 in Macbook Pro's except he has 250 gb and I have 350gb. Everything else is the same even the wireless card. The problem is, he can see and connect to a unsecured wireless network but i can't. Why is this ?
Our computers can see the same networks on the list but my Macbook does not see one network, the unsecured network !!!

I never said there wasn't an issue, just that blame could not be assigned based on what we know now and that there are many more people not having problems with Leopard and WiFi than those that are.
In my circle of associates I know of literally hundreds of Mac owners, of which approximately three are having WiFi issues.
I know how frustrating it is to be one of those afflicted - my stories of constant WiFi drops for the first six months I owned my MBP have been recounted in several threads.
But it's just as frustrating to read how Leopard is just plain broken when in fact I've not seen a single WiFi drop in Tiger or Leopard since February 2007.
This is also why I've continually urged people experiencing the problem to open an AppleCare case - it's only then that Apple Engineering can find the commonalities in cases where WiFi is failing and either fix their driver or notify the router manufacturer of their bug.
Are there bugs with AirPort in Leopard? Of course, and I even know of one that affects me on occasion that's known, and that's a failure to reassociate with a known network when waking from sleep. The workaround is simple - toggle AirPort off and back on - but it's a known issue nevertheless.
But each of these threads addresses an individual problem, and among the numbers of people experiencing difficulties, few report that their Mac sees no wireless networks, and that's what the advice I've given in this thread is geared towards.

Macbook Pro will no longer connect to my network automatically

My network used to connect automatically and now I have to manually connect. In Network Connections it doesn't show to be set up any longer so I set it up again but it will not save it after I shut down. Any ideas? Thanks!

Try loging into your router settings and just change the name of your network. That usually works for me.

My Macbook Pro will no longer recognize my iPod mini...

My iPod mini has worked well for over two years now. I haven't connected it since I downloaded the latest iTunes (7.6.2). I also just dropped it on a relatively hard floor (thin carpet, with tile underneath it). When I picked it up and plugged it in, it showed a folder icon with an exclamation point. It does not seem to be charging and it is not recognized by my computer at all. I tried the the first 4 of the 5 R's and nothing happened. I cannot restore my iPod because my computer won't recognize it, whether in Finder, iTunes or in the iPod updater program. Does anyone know of a way to fix this, or is my iPod broken?

Hi there joe.l,
If I understand correctly your computers DVD/CD drive isn't seeing your install disc to boot from. If it is also not recognized in the OS when you boot, I would recommend the following section of this article to help you out here:
Get help with the slot-loading SuperDrive on your Mac computer
Accepts discs but they don't mount or are automatically ejected
Make sure the drive is not placed upside down. The aluminum enclosure should be facing up as shown in section 1.
Check the disc's surface for scratches and dirt, since these things can prevent the disc from appearing on the desktop.
Connect the MacBook Air SuperDrive directly to the computer's USB port instead a USB hub.
Reset the System Management Controller (SMC).
Ensure your drive can read the specific type of disc being used. The System Profiler or System Information may provide additional information regarding what media your computer supports.
OS X Snow Leopard v10.6 or earlier: Open Apple System Profiler by choosing "About this Mac" from the Apple () menu. Then, click More Info.
OS X Lion v10.7 and later: Click the Apple () menu and then hold down the Option key. Choose System Information from the menu.
If the disc continues to not be recognized, contact Apple or an Apple Authorized Service Provider, or make an appointment with an Apple Retail Store.
Thank you for using Apple Support Communities.
Regards,
Sterling
