Apple Macbook Pro Retina with display issue Samsung LED

Once I have plugged the HDMI cable from Macbook Pro to Samsung 24" LED Monitor, the display remains black. Doesn't seemed like the samsung monitor recognised the Apple Macbook Pro at all. I have reset the PRAM and troubleshoot it with Apple and meanwhile still waiting for answer from Apple. They have acknowledged of the problem but there is no solution. I erally need the second extended monitor for my design work. Bit ridiculus that the most powerful Apple system cannot even do the simplest thing. I am stuck now. Please help.

Just letting everyone in the forum know that I have been a loyal user of apple for the past 20 years and this is quite embarassing to know that HDMI cannot work with a samsung LED monitor. In addition, I have been a Apple Tech and Sales.
Also, there are a lot of users out there who are having the same propblem,. This is certainly not good enough.
I still find it wayyyyy too early to blame Apple so generally. This other "lot of users" has a lot of home-made problems, such as incompatible displays, adapters, etc.
BTW, mind telling the exact display model number?
And thanks for the response further above.

My apple macbook pro retina 15'' ME664 has problems with sound.Either there will be no sound at all or at startup there il be very scary and broken sound and afterwards still there would be no sound.Secondly , it does not start in one shot.atleast 2 to 3 times pressing power button for longer time starts it up and afterwards still there will be no sound. Please help

This morning i was not able to hear sound on my recently purchased macbookpro retina 15 inch model.My attempts to resolve this issue by going to system preferences and removing the mute box that was ticked as active. i had downloaded much earlier a mac version of logmein app and noticed that in the sound box noted above that there was a bar indicating that the default was now to logmein. i had never used this app. Why it started today, i have no idea. I moved the logmein application to trash and deleted the app , however it did not remove the default option which still blocked the sound.
Going to a macforum gave the tha anser that to remove the logmein app, it first had to be reinstalled a nd them use the uninstaller option ftrom the dropdown menu. for now that has resolved the failure to allow sound oputput.

Macbook pro retina with ghost image problem

Can i claim my retina display that have ghost image problem?

Hi there, I had the same problem with my Macbook Pro 15`` Retina. And here is how you can find out if you have ghost image problem. There are two retina display manufacturers for Macbook Pro Retina`s LG and Samsung. And if you are luck you will have the Samsung Retina Display on your mac. Here is how you can find the manufacturer for you Macbook.
Go to your Applications folder and launch Terminal. Paste in the following and hit return:
ioreg -lw0 | grep "EDID" | sed "/[^<]*</s///" | xxd -p -r | strings -6
Look at the beginning of the second line to see which manufacturer made your display. If it starts with LP then you have an LG display. Samsung displays start with LSN.
If your display shows LP you might have this problem for sure. So here is how you can test your screen.
A simple test to check your Retina MacBook Pro display for image retention also reported as "ghosting"
http://www.mitchmalone.name/retina-test/
Run the test for 10 Min. and you will find out if you have this problem.
And if you have it, and if you are still under waranty the Apple will replace the display with Samsung for free of charge. I hope this information helps.

FaceTime on macbook pro retina with Mavericks

I have just bought a 15" macbook pro retina with Mavericks and FaceTime has never worked. My account works fine on my iPad and iPhone but macbook version just won't connect and says 'FaceTime call failed. Can anyone help?

Hello there, alparkinsonpm.
The following Knowledge Base article offers up a few good steps for troubleshooting FaceTime on your Mac:

MacBook Pro Retina with a 500gb hard drive - 400gb storage space?

I have a MacBook Pro Retina with a 500gb hard drive. I recently deleted a windows 8 partition, and now my macbook says its total storage capacity is 399.42gb. Is this normal? Or am I missing 100gb storage space?
When I deleted the partition through boot camp, there was an error, but the boot camp partition seemed to have been deleted completely. I ran disk utility repair and single user mode command prompt /sbin/fsck -fy to make sure my disk was properly partitioned, but it still shows 399.42gb total storage in my "About This Mac".

You did not remove your Windows partition correctly. You need to remove it using Boot Camp Assistant. If you cannot then you will need to repartition the entire drive back to a single partition/volume.

Macbook Pro Retina with Samsung 2053BW

I recently bought a Macbook Pro Retina that I was planning to use with my Samsung 2053 22" monitor (1650x1050) and bought a MiniDisplay Port aswell.
However I can not seem to get this monitor to work with the Macbook Pro.
The Samsung monitor works fine with my windows desktop and has done so for years.
I also went to the local applestore here and got them to test both my MiniDisplay Port with an external monitor with my DVI-D cable aswell.
They did not test it with my Macbook Pro Retina as I did not bring it, but will most likely go and get them to test that also.
Though I think the problem is with the compatability between the macbook and the samsung display.
Does anyone have anything else I can try or suggestions for my problem? I have also tried resetting the pram without any results.

Macbook pro retina a1502 display assembly cost in india

My macbook pro retina a1502 screen broke. It has a small crack on the top right corner. I wanted to replace the screen only but as it is not available I want to buy the display assembly to replace the broken screen. But I don't know how much will it cost in india....please help

Don't worry, there is nothing wrong with your computer. I have the same issue, and it is a bug. Sometimes a restart solves it. Sometimes and if you use subtitles, you will see the first line being displayed but the second one not, etc.
I have reported that to Apple and there is hope for a fix.

Trade in value, 10 month old Macbook Pro Retina w/ WIFI issues?

I have a late 2013 Macbook Pro, Retina, upgraded memory from base model, 256 of awesome Samsung PCI-IE storage with the apparently very common wireless card issue. Web pages don't load, erratic ping times and high packet loss. It was purchased at an Apple store.
What is the common scenario one would expect if they simply want the new model, or would I be making an assumption that the wireless card issue was resolved at some point?
As a consumer, what would you expect?

I would have expected that you would exercise your warranty. We are only users like you. No one here can be expected to know what your scenario would be like. But every day you waste on these forums is one day less remaining on your warranty.

Macbook Pro Retina External Display Audio

I am looking to get a Macbook Pro Retina 13" and I want to connect an external monitor to use as my primary display when at my desk. How would I get audio to work when my Macbook is closed and I am just using the external display. (Using DVI-D cable)

I have a new rMBP 15 and I am having a major problem with hooking up to external projection systems. Otherwise, it's a fantastic computer for running Windows (required for work) and Mac, my preference.
I have to often hook up to an external projector at various companies for presentations and I never know which type of projector they will have. Most are VGA and and most do not work with the Apple TB-VGA because it sees them as 640x480. I finally found a solution with an "active" VGA adaptor from Cirago:
http://www.amazon.com/gp/product/B005AT2KTK/ref=oh_details_o00_s00_i00?ie=UTF8&p sc=1
However, now that I have higher resolution the image is blurry much like the OP but even worse and not usable. I am going to experiment with various settings I have found on other posts and forums, but most are specific to a fixed setup, whereas I need plug&play and don't have the time to fiddle with settings before each presentation.
My fear is that I may have to abandon the rMBP and revert to my old clunker DELL, due only to this one major issue issue.

Macbook pro Retina 15" reboot issues

Hi all
I am a newcomer to the community.
Right I've had the my brand new macbook pro retina 15' since the begining of september 2014 which came with Mavericks.All seems fine back then
I did the terrible thing and upgraded to the yosmite when it came out and I've starting to have issues , with the wifi dropage etc etc
My most recently issue which has come to light is that , after I've RESTORED Yosemite many times (yesterday was the last time) when ever i use the computer and then reboot after few minutes to some time the computer takes super long and hangs at rebooting???????
I get a that "progress spinning chopped up circle thing" staright after i reboot and sometimes it just hangs there with the Fans going full blast till i need to hold the power button down! like what the ****
does anyone have this issue? or know how to resolve this? or do i need to bring it back to apple?
My macbook is top spec 15 inch Mid 2014 one with only the minus of the 1tb hard drive upgrade , however i feel its should not be having these problem.
I must admit since i have the macbook pro , I've used Parallels a lot , bootcamp and FileVault encrypting (which is now turned off) testing things out. i thought as this is a top spec it should handle this no problems as i got this for a development machine. Ever since Ive got Yosemite its like its slowed down and become sluggish.
When I had maverick i did not experience a ton of problems like Yosemite, it booted up in 8 secs and shutdown immediately althought i did not test the file vault encrypting under mavericks.
Also sometimes when my Fans will be on full blast when i am not doing anything intensive, like when i browse with chrome or finished with parallel.
I be grateful if anyone can help me solve this since its now not a issue of restoring which I've done many times. I dunno if I've pushed the SSD to to much or something......
Is there a way to revert had to mavericks? without a usb or cd
Thanks
Zyco

Before trying to go back to Mavericks, try performing an SMC and NVRAM/PRAM reset. These two components control several functions of your MacBook Pro and by resetting them to their default values it may clear up the issue that you're seeing.
To reset the SMC:
Turn off your computer and ensure the MagSafe adapter is plugged in.
Hold down Shift-Control-Option on the left side of your keyboard, and then hold down the Power button at the same time.
Wait about 5 seconds, and then release the keys. You may see the light on the power adapter change colour momentarily.
Don't turn the computer on just yet, we'll do that in the next step.
To reset the NVRAM/PRAM:
Press the Power button and then immediately hold down Command-Option-P-R on your keyboard at the same time.
Continue holding these keys until your MacBook Pro restarts and you hear the start up chime a second time.
Release the keys and continue booting into OS X.
If this doesn't work, try booting into Safe Mode. This will help you determine whether a software issue is causing your problem. To boot your Mac into Safe Mode, restart the computer and hold down the Shift key until you see the Apple logo appear on the screen. It may take a little while longer to boot up as OS X will verify the state of your disk and clear out certain caches and temporary files. Once booted into Safe Mode, try restarting and see if the issue persists.

Is my Apple MacBook Pro Retina a Lemon?

Brand new(7 days old) MacBook Pro Retina 2.4GHz 16GB SSD 15" with latest OS updates. I treat this MacBook like it is my newborn child. I am extremely careful with the hardware AND software configuration, almost to the extent that it's a compulsion. I have used multiple computers with Windows, Linux and Mac operating systems. I take extra time to find out the best way to treat computers as to avoid troubles like these, so I feel especially upset about losing two hours of work on my clients project. Luckily everything is backed up on GitHub and Dropbox.
I used a great tutorial from mactuts on setting up a new mac the way that developers do, and I have set up Windows and Linux just fine. I doubt there is a system or program configuration issue on my part. I was running a few programs that are not processor or RAM intensive.
- Sublime Text 2
- Google Chrome
- CodeKit (Sass compiler)
- iTerm2 (terminal)
- Dropbox (was not syncing)
- Moom (window arranging utility)
- Alfred (app and file finder utility)
There were absolutely no peripherals connected to the MacBook, no mice, USB devices, or even headphones. Only apps running.
I was typing code into Sublime Text 2 and I saved the file, watched the browser for live changes on the web site I was working on (thanks to CodeKit) and the page refreshed fine, when I moved the cursor via the touchpad back to Sublime Text 2 from the Google Chrome window, I was greeting with a 100% frozen MacBook Pro. The entire GUI was stuck, no keys would function at all, and I didn't know what to do. I searched for answers, couldn't find anything, and I held down the power button until the MacBook turned off. The computer was not hot at all during this time.
I restarted the computer after some more searching and found instructions on verifyng the disk. All is fine according to the system Disk Utilities. I just got done with a 1 hour and 6 minute Apple Hardware test with the extended testing option checked. No errors were found. The aluminum north of the function keys got SUPER hot.
The MacBook has done something similar twice before but I shrugged it off. I was doing similar tasks as may have triggered the recent problem, but the freeze only lasted seconds instead of forever. How could a 2600 dollar computer freeze during text editing and web browsing? Have I been sold a lemon? Is this a common problem? Can this problem be corrected? Can the cause of this problem be eliminated?
I have another laptop that is over 4 years old (Toshiba Sattelite) running Ubuntu 12.04 LTS. It has never had a problem running simple text editors, code watchers/compilers(Sass/Compass/Guard), or browsers, even all at the same time. From the reputation that Apple has, I was expecting more. I figured the computer might have a few hiccups if rendering a huge video file, or running 3 external monitors with Photoshop and Illustrator open and working, but definitely not with the programs I had open.
I switched to Apple to learn iOS and OSX development, to make awesome apps. I am 90% sold on taking this back to Apple and getting a full refund, never to go back. I hope someone can help change my mind and fix my computer.
Thank you so much.
Chad

Ah! A Linux user. That explains things. I wondered why you were installing a bunch of stuff I had never heard of on a week-old computer.
The bottom line is that OS X is not Linux. It may look like it sometimes, it shares a few libraries and some command-line tools, but it is completely different. Your old Linux habits will only cause you trouble.
The big question is what 3rd party software have you installed? You listed a few, but there have got to be others. It is a sad fact that OS X has zero credibility among most most corporate and open-source software developers. There is a vast amount of software that hasn't been updated in almost 10 years. How far would you get installing the latest and greatest Linux tools on a Linux box circa 2007?
As a new Mac user, you are unfamiliar with what software is good and what isn't. Some of the software you listed above is fine, but why install it if the operating system already comes with equivalent functionality? There is nothing wrong with doing that if the Apple software doesn't do what you need. But just doing it out of habit or because it is some open source project is likely to have poor results. For example, OS X version 10.8.4 was recently released. Well-written software from 2006 will run fine. Poorly written software from last week will crash, cause slowdowns, and all kinds of other problems.
If you don't have a good reason for using Chrome instead of Safari or iTerm instead of Terminal, then you are likely going to be at the mercy of 3rd party developers who have more control over your system than you do. Make yourself at home and learn your way around before you invite a bunch of rowdy kids over for a party. Later on, you can throw some parties and have fun, but you will be the one in charge. Right now, they are probably running wild in your basement reconfiguring your plumbing.
This is so common that I wrote a little diagnostic program to help show what might be causing these problems. Download EtreCheck from http://www.etresoft.com/etrecheck, run it, and paste the results here.
Disclaimer: Although EtreCheck is free, there are other links on my site that could give me some form of compensation, financial or otherwise.

Jaybird headphones and Macbook Pro Retina bluetooth connectivity issues

I recently purchased the Jaybird Bluebuds X Premium headphones and for awhile it would connect to my new Macbook Pro Retina 15'' via bluetooth, but now it doesn't anymore. The headphones connect just fine to my phone (iPhone 4S), and other Macbook Pros (not retina), but they do not connect to other Macbook Pro Retinas. I was wondering if this was a connectivity issue with Macbook Pro Retinas and if so how can I get around it to connect the headphones again?
Thanks

Hey there LongHorn16,
It sounds like your Bluetooth headphones aren't working with this one computer, but there is no issue with other devices that you have. I would start with these 2 steps from the following article:
Restart your computer
Sometimes a simple restart of your Mac is all it takes to get things running smoothly again. You may also want to try resetting your computer's PRAM and NVRAM.
Reset your Bluetooth device
Try turning your device off and then on again. If that doesn't resolve the issue, see if you can reset your device—refer to the documentation that came with your device for instructions.
Bluetooth Quick Assist
http://support.apple.com/kb/HT1153
If it still doesn't work, then I would next use this article to remove the device:
Bluetooth: How to Delete a Paired Device
http://support.apple.com/kb/TA27116
Then restart your computer and pair it again:

Thank you for using Apple Support Communities.
