Alert tone ("funk") when waking or sleeping display on 15" MacBook Pro Retina

When I wake my computer from sleep an alert tone sounds (it is called "funk"). I'm on a 15" MacBook Pro Retina running Mountain Lion. If I manually sleep the display or if it does it automatically this also occurs (shift-control-power on my computer). Anyone having this issue?

Or even any insight would be appreciated

Is there a display for my MacBook Pro retina that isn't made by apple and doesn't cost the world?

Please tell if there is a display for my MacBook Pro retina that I don't have to pay tons for and will connect to my laptop!

I just plugged my 13" MBPr in to a cheap 24" 1080p BenQ using a Display port to DVI adapter and it works fine, crisp enough for my eyes and for around £115 a bargain.
edit: Picked it up from Amazon on a free next day delivery with Prime.

When I turn on or restart my Macbook Pro Retina 15", my entire screen flashes completely bright yellow for a few seconds and then it goes to the normal Welcome screen. How do I fix this??

Hi Everyone,
This problem just started today. When I turn on or restart my Macbook Pro Retina 15" (Mid 2012 version), my screen is light gray like normal, and then after a few seconds my entire screen flashes completely bright yellow for a few seconds, and then it goes to the normal Welcome screen (where I choose to login as myself or a guest user). This suddenly started today and has not stopped since. This keeps happening every single time I turn on or restart my computer.
Yesterday I installed all the Mavericks and other updates that were available in the App Store, so I'm wondering if this is related to that since this never happened prior to my doing those updates yesterday. When I first installed the new OS X Mavericks (10.9.3) update, it went through the whole installation process (took about 10 minutes), and then during the installation I got an error message saying that it couldn't verify my iTunes application that was on my laptop, and then my laptop finished installing the updates. Then once my laptop restarted, the App Store "Updates" section said that I had to do the whole OS X Mavericks (10.9.3) and iTunes (Version 11.2) updates all over again. So my laptop did the whole installation again (took about 10 minutes, but this time I didn't get that "iTunes error message" during the installation process).
Now, when I go to the App Store "Updates" section, it says the following under "Updates Installed in the Last 30 days":
-Digital Camera RAW Compatibility Update (Version 5.05) installed May 15, 2014
-OS X Update (Version 10.9.3) installed May 15, 2014
-iTunes (Version 11.2) installed May 15, 2014
-OS X Update (Version 10.9.3) installed May 15, 2014
-iTunes (Version 11.2) installed May 15, 2014
-Security Update 2014-002 (Version 1.0) installed April 22, 2014
I'm wondering if this flashing bright yellow screen upon bootup is related to the fact that my laptop installed the OS X Update and the iTunes Update two times each? Or is this new problem totally unrelated? It's just that this problem started a day after these 2 updates were installed twice.
My Macbook Pro Retina 15" (Mid 2012 version) is otherwise working fine at least as of now. The only issue so far is this flashing bright yellow screen every time I turn on or restart my computer.
If anyone could please help me fix this so that my bootup screen doesn't flash completely bright yellow anymore, I would be forever grateful!
Thank you so much for reading this and for any help you can provide.
hope everyone is well,
Elaine

Hey everyone in Apple world!
I figured out how to fix the flashing yellow screen problem that I've been having on my MBP! Yessssss!!!
I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
I followed the instructions on this page and here's what I did:
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process. Since I did that, my MBP boots up just like normal. No flashing yellow screen anymore!!
(Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
Let me know if this works for you!

Can i run 3 displays with 13" macbook pro retina?

I need to run 3 external displays from the macbook pro retina. Does the 13" retina have the capability or would I need to go with the 15" retina which has the Nvidia with 1Gb memory?

you will need the 15" model

Extending my desktop across 2 (DVI) displays from 15" MacBook Pro Retina

Hi. I bought a new 15" MacBook Pro Retina a few days ago and am trying to connect 2 Dell displays with a view to extending my desktop across them both. At the Apple shop I was told I simply needed to buy 2 Thunderbolt to DVI converters (my 2 displays both have DVI out) and hook them up... Not true. If I try this my desktop only extended across 1 display. The other display isn't even picked up by my MacBook Pro.
So does anyone out there know how I connect 2 DVI displays to my MacBook Pro without buying a Matrox Dual Link? If I bought an HDMI to DVI converter cable and connected one display via the HDMI port, and the other display via the thunderbolt port, would this work?

May not be an upgrade issue ..
You have a fast processor. and 8GB of RAM is more than sufficient. (The processor cannot be replaced)
Click your Apple menu  top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space. Less can slow the system down.
If your Mac seems to running slower, try the suggestions here > Mac troubleshooting: What to do when your computer is too slow | Macworld
If you have not done so, especially with school files stored on the hard drive, make sure to back up your important data on a timely basis. Help here > Mac Basics: Time Machine
Not a good idea to post the serial number of your Mac on the net. I have asked the moderators to edit that information for you. It has nothing to do with upgrading.

Dual 27" Thunderbolt Displays on 13" MacBook Pro Retina

I'm thinking of buying two Thunderbolt Displays and make my 13" MacBook Pro Retina my main desktop computer. So the question is:Can the 13" MBP handle two chained Thunderbolt Displays without getting slower or will the Intel HD 4000 just melt down?
I might wait until Apple announces the next generation of Thunderbolt Displays tho as I think this will happen soon (probably when the new Mac Pro is released?)...

You could try changing the DPI. If you use startx, use this:
startx -- -dpi 100
Try experimenting with different DPI values.

IPhone 6 Plus 64GB (iOS 8.1 or 8.1.1) springboard crashes repeatedly when making phone calls via Continuity on Macbook Pro Retina Mid 2014 using Yosemite 10.10.1

I USED TO be able to make phone calls using continuity on my MacBook Pro (Retina, 15-inch, Mid 2014) with Yosemite (10.10) via my iPhone 6 Plus on iOS 8.1 without any problems. Once I updated Yosemite to 10.10.1, my iPhone's springboard would continually crash where it brings up the Apple logo and quickly restarts repeatedly until I end the call. Just so that you know, I am able to stay on the call while this is occurring the whole time.
I need to reiterate, this all started happening as soon as I updated Yosemite to 10.10.1 while still on iOS 8.1. I know this because I made a few phone calls (loving the feature), updated Yosemite to 10.10.1, then made a few phone calls afterwards, and this started happening.
When iOS 8.1.1 came out, I eagerly updated hoping this issue would go away, and it did not. I'm hoping Apple notices this post. If anyone else has this problem, please contact Apple and chime in this post as well. Thank you Apple for incorporating continuity calling. I love this feature, but need to use it without my phone's springboard constantly crashing.

I have this issue as well. I am using an iPhone 6 plus, iPad Air 2, 5K iMac, and MacBook Pro. When I make a continuity calls from any device, the springboard crashes. This only happens with outgoing calls, incoming calls are functioning normal. I am currently working with multiple Apple Senior Advisors, and they are working directly with iOS a engineers. I have an active open case and will update this thread when a resolution is found.
Just a tip for everyone with this issue, restoring your devices and setting them up as new WILL NOT correct this issue. Save yourself the hassle. I did this with my iPhone, iPad, and MacBook and the issue still persists.

Dual Dell Displays for my Macbook Pro Retina (Late 2013)

So I am looking at purchasing two of the new Dell Ultrashapr U2414H monitors to hook up with my Macbook Pro Retina. I have been trying to figure out the best way to connect both of the screens before I order them and I was hoping someone on here could offer guidance.
Connectors for the U2414H:
     1. 2 HDMI(MHL) connectors
     2. 1 Mini DisplayPort
     3. 1 DisplayPort (version 1.2a)
     4. 1 DisplayPort out (MST)
Also, if anyone has any ideas of a better monitor that I should look into PLEASE let me know. I am very open to suggestions on what types of monitors go the best with the Macbook Pro Retinas.
Thanks!!!!

I have just purchased a MBPr 13" along with 2 x Dell U2414h monitors in the hope of being able to daisy chaing the monitors. If i enable displayport 1.2 on both monitors then i end up with the 2 dells mirrored.
If i plug the monitors both directly into the mac over minidisplayport to displayport cables then i have 3 displays running (the MBPr and the 2 x Dell's). What i really want is to be able to daisy chaing 1 of the dells of the other one and then connect that one to the MBPr. But i cant work out how to stop them being mirrored.
Anyone actually got this working?

Issues with External Displays on my Macbook Pro Retina

Hello -
My apologies for starting a second thread back to back, but I thought I'd keep these two issues separate
I've been using two external displays off of my Macbook Pro Retina for some time - one off of the HDMI port and the other off of a Thunderbolt to HDMI adapter. Everything was absolutely perfect until the most recent update. Immediately after that, whenever the macbook wakes up, the two external displays go into this black and white snowy mode (like the HBO logo, or that thing from poltergeist) and takes a minute or two to start working properly. Any suggestions on how I can fix this?
Thanks.

Hi there,
Just browsed the forum and found a fix which solve the issue in my context: Google Chrome Play Music app was actually swallowing the media keys events, preventing iTunes to get them.
Still don't really understand why it impacts only iTunes in my case, however once the Play Music app uninstalled from Chrome via the Extensions pane of the Settings page, iTunes got its media keys events back.
See this thread for reference:
Media keys not working on MacBook Air
Cheers

Start up and waking from sleep problems. early 2011 macbook pro i-7 2.0

Been having problems with my computer starting up and waking from sleep. If i shut the lid it wont wake up upon reopening the lid unless i hit the power button. After hitting the power button it will restart automatically and you hear the chime and the cdrom ejecting , once the gray screen pops up it restarts again this time you hear the cd rom making the ejecting sound twice then it will start up as normal. Once it finally starts up my date and time has been reset to jan 2008. Other times when i open the lid hit the power button it does nothing at all. Even holding the power button for multiple seconds to force shut down it does nothing. Only way to get it to start up at that power is if i connect the charging cable. I have tried reseting the smc multiple times with no results and pram(even though it doesnt have anything to do with start up problems just did it anyways). It all started i last time i updated not completely sure what all updates i got but im still running 10.7. It seems like a battery issue which would make sense since its nearly 3 years old and i use it extensivly. Last thing that just started recently after i go threw the whole mess of getting it to start up if i pick it up or nudge it the thing will just shut off out of no where. Almost like there is a short somewhere, cant really be sure if its linked with the waking up from sleep/start up problems but seems right up the same ally. Any suggestions to what could be wrong would be greatly apreciated. Im assuming my battery may be on its last leg but the thing still holds a charge and my battery life hasnt dimished at all so cant really be totally sure. Thanks agian

Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. It may not fix the problem but it would be the first thing an Apple Store would do if you were to bring it to them with this complaint.
If bumping the Mac causes problems it's an intermittent internal connection that the SMC reset is not likely to help.
Read all the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. The power adapter indicator light will cycle off / on once.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

Connecting HP 2311x display to new macbook pro Retina - no output on external screen

I have a brand new MacBook Pro 15 in. with Retina display. I also have a HP 2311x monitor. When I plug in the HDMI cable, the external monitor says "check video cable" and the preferences "arrangement" thinks there is a display - even recognizes the type - but the external display just wont display anything but the "check video cable" box. I spent 2 hours on with apple yesterday, they had me do all sorts of resets and stuff - but no luck. The HDMi cable works when connecting a pc to the screen. When connected to by macbook, the screen on the macbook likes to flash black and its annoying. I have gotten really used to working with two screens.... and apple's suggestion was to buy a thunderbolt cable and try that. As it is, with this new macbook I have to buy a bunch of cables, I really don't want to buy another one when I am not sure that will work. Darn things are expensive when you are buying 4 connectors at once (ethernet connector since the speed via wireless is noticably slower; magsafe to magsafe2 converter; thunderbolt for my printer; and a connector for the monitor at home which doesn't have an hdmi port).
Any other suggestions before adding another to that list? Since Apple seems to be out of ideas... any info would be appreciated.

I have an HP 2311x as well. I'm using an HDMI cable and am not having any issues getting the screen to display. I know you said the cable works with a PC but have you tried a different HDMI cable just in case. It might be worth a try. Other than that, I'm not much help.
The issue I had when plugging this monitor into my MBP retina was that the image was very blurry on the HP 2311x. I almost gave up on using it and was going to just buy a Thunderbolt display but after much research I found a custom firmware update that fixed the underscan/blurriness issue. So be prepared for that if you get the screen to display.
If I can find that resource, I will post it here.
Good luck!

How to lower the brightness of my iMac, when used as external display for my MacBook Pro?

The keyboard brightness controlls of the iMac do not work. The keyboard brightness controlls of the MacBook only controll the MacBook. Same goes for the display set up of the MacBook, I can change the MacBooks brightness there but not the one of the secondary screen.
I am working in a pretty dark room and that iMac 27 is at full bightness. Gives me a headache. Please help.
Thanks

4k display support on MacBook Pro Retina 13" vs 15"

Is there a difference in the 4k support of the current MBPR 13" vs 15"?
Specifically:
* does Iris 5100/5200 vs NVIDIA GeForce GT 750M make a difference?
* do either support connecting two 4k displays?
Thanks

The big problem with either is the battery will likely die before then, and so will the warranty. So you'll want to save up to be able to replace the battery in that time frame. Both are fine machines, the larger the screen, the more real estate you'll have for windows on the screen. Backup your data regularly, as no medium is safe from failure.
