I have macbook pro retina - a month old
For last few days a siren comes up randomly - like the arcade games ....

I agree that the temperatures that you are reporting do not require the fans to increase speed. However as a precautionary measure you might do a SMC reset:

Does the macbook pro retina 15 inch comes with cd/dvd drive?

Hey
Does the macbook pro retina 15 inch comes with cd/dvd drive?
thanks

The MacBook Pro with Retina display doesn't come with a CD/DVD drive. Instead, you have to buy the Apple USB SuperDrive or any external optical drive, or you can use Remote Disc if you have another Mac > http://support.apple.com/kb/HT5287

Why does my new MacBook pro retina with 16gb ram keep randomly freezing

Why does my new MacBook pro retina with 16gb ram keep randomly freezing

Hi ..
A new Macbook Pro should not randomly freeze.
You have 14 calendar days from the time your items are delivered to initiate a return as noted here.

The plastic hinge between my screen and the computer (macbook pro retina) is cracked and doesn't hold the screen anymore? Can Apple change it?

The hinge between my screen and my computer (macbook pro retina) has cracked and doesn't hold the screen anymore. Can I fix it without changing my screen. And if it's still on guarantee does Apple have to repair it?

Apple can fix any and all of their computers. Whether it would be charged to you would be the question. Do you have AppleCare?
Accidental damage is not covered by AppleCare.
How old is this computer?

Brand new MacBook Pro Retina display wont come up at all.

I got a brand new MacBook Pro retina display a week ago. Since yesterday, it won't come up at all. Screen stays blank, no HD sound, nothing. Does anyone else have same issue which they resolved already?

I did call them and it seems there is no solution except sending it back to them and getting a new one.
This is by far the most strange issue I have seen. Seems more like a hardware issue than software.
Thanks for you suggestion though. I will post an update ones this case gets resolved.

MacBook Pro retina 13" (late 2013, Haswell) why is the highest resolution rendered in 3360x2100, which the system obviously can't handle?!

Hey Apple and Apple users,
I just recently switched from an MacBook Air (mid 2013) to the new Haswell MacBook Pro retina 13" (late 2013 model).
The main reason to do so was the better screen and the option to run higher scaled resolutions, as advertised.
I was willing to trade in the Air's low weight, smaller formfactor and the extra batterylife for the better screen.
When it comes to resolutions:
1280x800 is just a joke nowadays, why is the MacBook Pro still based on it? 13" and 1440x900 work quite fine...see MacBook Air.
1440x900 is okay in everyday life situations, but sometimes you just need "more space" as the third scaling option calls it as well in the display-settings.
1680x1050 on 13" can sometimes be challenging, but it is really fine if you need to work and have a lot UI elements to deal with (Photoshop etc.)
So 1680x1050 scaled on the 2560x1600 screen would be my daily driver for work. So I expected a scaling factor of "1.5238..." (2560/1680) will be used most of the time.
Frankly spoken...I am really disappointed by the 13" retina MacBook Pro and the way OS X Mavericks is handling the scaling.
It obiously works well and responsive with the 1280x800 non-scaling resolution ("best for retina, scaling factor 2: 1280 --> 2560).
Is still "okay-snappy" at 1440x900 (scaling factor 1.777...: 1440 --> 2560).
But it totally breaks down at 1680x1050 (scaling factor 1.523...: 1680 --> 2560).
I use "Mission Control" all the time and it is stuttering and slow...overall a sluggish and unbearable experience.
The same goes for Desktop-Switching by swiping the screens or resizing and moving windows and files around.
So I was wondering why...and then I noticed that when taking a screenshot of my entire screen (CMD + 3) the image size of the screenshot was 3360x2100 and not the expected 2560x1600.
This means Mavericks is not scaling the UI with the appropriate factor (see above). For retina MacBooks it ist simply rendering one pixel of the classic, non-retina Interface in now 4 pixels (2x2) and sending this straight to the screen, which then "scales" it down to the resolution it is able to display.
Why is this bothering me? – Because the machine has to do a lot more work to render the higher resolution that can't even be displayed, due to the screens limitations.
2560x1600 = 4096000 pixels = 100%
3360x2100 = 7056000 pixels = 172%
This means the MacBook has to render 72% more information than actually can be displayed on the built-in screen and are just lost.
Of course this makes the overall UI feel sluggish and idly! Especially with the not that performant Intel Iris IGP and no dedicated graphics card.
All this extra "rendering" just results in a worse battery life due to the extra work that the graphics card and CPU have to do.
First, Apple...are you serious about this?
What can we do about this?
Is there a way to have this properly scaled?
Thanks in advance to everyone.

Okay...I thought deeply about this issue.
Even looking into ways to maybe fixing this on the software side. But it occured to me that this is to deeply embedded into the system that it won't be possbile to come up with a sufficient third-party solution.taht
The problem is that there is no intermediate step inbetween "standard DPI" graphics and "HiDPI" (image-resources named "[email protected]").
But there should be one, to minimize the amount of image information that needs to be processed by the device.
This effects especially the MacBook Pro retina 13", as it has the less powerful Intel Iris IGP, when performing on the highest scaled resolution (equivalent to 1650x1080).
As well as the MacBook Pro retina 15" without a dedicated, second Graphics Unit,when performing on the highest possible scaled resolution (equivalent to 1920x1200).
Those devices don't have enough resources to handle the consequential "HiDPI" resolutions of 3360x2100 for the 13" and 3840x2400 for the 15" model.
(Comment: 3840x2400 = 9,2MP, which is more than the standard 4K resolution of 3840x2160.
I analyzed the scaling factors as follows:
Factor "2" to display 1280x800 on the 13" model and 1440x900 on the 15" model in HiDPI.
Factor "1.777..." would be required to display 1440x900 on the 2560x1600 screen of the 13" model.
Factor "1.714..." would be required to display 1650x1080 on the 2880x1800 screen of the 15" model.
Factor "1.523..." would be required to display 1650x1080 on the 2560x1600 screen of the 13" model.
Factor "1.5" would be required to display 1920x1200 on the 2800x1800 screen of the 15" model.
As all the models seem to have no problem with rendering the intermediate scaling step (1440x900 for the 13" and 1680x1050 for the 15" model) at HiDPI, hence with the scaling factor 2. There is no real need to provide the UI-elements.
But in my opinion there is a strong need for a "MidDPI" ([email protected]) intermediate step for all the UI graphic elements that wis based on the scaling factor 1.5.
This would result in the following:
13" MacBook Pro retina with 2560x1600 screen:
1280x 800 @ 2x = 2560x1600 (no surplus, native screen resolution)
1440x 900 @ 2x = 2880x1800 (the surplus of 1088000px = ~1MP can still be handled and compansated by the weak Iris IGP)
1680x1050 @ 2x = 3360x2100 (the surplus of 2960000px = ~3MP is too much for the weak Iris IGP)
NEW 1680x1050 @ 1.5x = 2520x1575 (with a small border of left=20px, bottom=13, right=20, top=12 pixels, which means ~2,2mm and ~1.3mm around the 1.5x scaled image!).
15" MacBook Pro retina with 2880x1800 screen:
1440x900 @ 2x = 2880x1800 (no surplus, native screen resolution)
1680x1050 @ 2x = 3360x2100 (the surplus of 1872000px = ~2MP can still be handled by the Iris Pro IGP)
1920x1200 @ 2x = 3840x2400 (the surplus of 4032000px = ~4MP can't be handled sufficiently by the Iris Pro IGP)
NEW 1920x1200 @ 1.5x = 2800x1800 (nu surplus, native screen resolution, no border needed!)
The big advantage is that all the graphics have already been remodeled for the HiDPI mode.
So scaling those "factor 2x" images down to "factor 1.5x" should be comparably easy!
Example:
Left: Traditional "standard DPI" icon of "all my files".
Right: "@2x.png" for the "HiDPI" modes.
Middle: "@1.5x.png" suggestions for the "MidDPI" mode; easily scaled down from the lovely HiDPI graphics.
With this simple introduction of the "MidDPI" modes a significant amount of processing power can be saved.
This not only improves battery life when driving those higher scaled resolutions, but also lets the user access those resources for what really matters: processing power for the primary job that the Mac needs to get done.
Thanks in advance.

How can I adjust the contrast of video on my MacBook Pro Retina so they don't look like they were filmed with an old sock over the lens?

I'd like to watch movies and TV shows, downloaded from iTunes or Amazon, on my MacBook Pro Retina, but they all look like they were filmed with an old sock over the lens. Daytime sequences look muddy, and night time sequences are incomprehensible with anything but the brightest objects rendered as black. I can watch the same files on my old MacBook Air and everything looks right, but no manner of tweaking seems to let me watch movies on my new machine.
I've tried adjusting the gamma. It's a bit better when gammas is set to 1.0, but I can't seem to set a gamma less than one. I tried using the Accessibility Contrast control, but it just lowers the contrast, swallowing my desktop into the dark abyss. I tried Applecare, but they don't have a clue. I tried the Apple Store. The "genius" confirmed that it is indeed impossible to watch movies shot anywhere but in the brightest sunlight on a MacBook Pro Retina, and it isn't just my machine, but every similar model in the store. He arranged for someone who really understands color profiles to give me a call, but Apple seems to have dropped the ball on this.
Is there some tool for stretching out the darker grays in Apple video? I don't want calibration. My impression is that my display, like the dozens I checked at the Apple Store are calibrated to make all dimmer grays appear completely black. I want uncalibration so I can actually see what is going on in the movies even if something is in a light shadow or shot at night. Hollywood has lots of trained technicians who can light and shoot night scenes that are quite comprehensible. I've watched a number of such scenes on my old MacBook Air. Now, I'd like to enjoy their artistry on my MacBook Pro Retina.

http://www.ifixit.com/ has directions for do it yourself. Also look at PRAM battery instructions, as sometimes this can fix optical drive issues.
You can get external or internal drives from http://www.macsales.com/
I also suggest in the future, take care of this problem while it is still under warranty. It may have cost you nothing.

Macbook pro retina 15 with win 7 in boot camp in games becomes hot and low graphics

hi i have macbook pro retina 15 and i installed win 7 with boot camp but when i want play games the first 2 minutes is good but the next minutes the macbook becomes very hot and graphics going very low i tried osx 10.8 but still not working. i tried command option shift power when mac is plugged in and off but still not working
does any one know solution of this problem??
<Edited by Host>

Hi All,
I tried this and it improved my FPS in games yesterday, still not getting FPS I would desire, but its become playable.
Repasted here from another thread:
My retina MacBook Pro has had terrible graphics performance problems for a couple of weeks. I searched all over various forums and tried everything: resetting SCM, manually selecting discrete/integrated graphics card, deleting graphics kexts, etc. Nothing helped until I found this: https://discussions.apple.com/message/19880198#19880198
Now my rMBP has silky smooth graphics again!
The directions in that post are a little hard to understand so I cleaned them up here:
Step 1: Delete system windowserver preferences
In the Finder, from the menu bar, select "Go -> Go to Folder..."
Enter: /Library/Preferences/
Delete the file called com.apple.windowserver.plist
Step 2: Delete user windowserver preferences
In the Finder, from the menu bar, select "Go -> Go to Folder..."
Enter: ~/Library/Preferences/ByHost/
Delete all files that start with com.apple.windowserver (On my rMBP, there was one file called com.apple.windowserver.12AFB147-95D6-5C70-8F62-C1E4F2BE81BE)
Step 3: Reset the PRAM (These instructions are from http://support.apple.com/kb/HT1379)
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.
Hopefully this helps others with bad graphics performance on retina MacBook Pros.
For anyone that wants to check out the problematic plists from my rMBP, here are the files:

My Macbook Pro Retina cannot be turned on. Although the welcoming chime is heard.

I have a macbook pro retina 13. I tried to turn it on but only the welcoming chime is heard. Even the apple logo illuminates. The macbook also can be charged. Just that the screen is black.

Reset PRAM. http://support.apple.com/kb/PH18761
Reset SMC. http://support.apple.com/kb/HT3964

Hello, I'm using a Macbook Pro Retina 13 inch Late 2013. Is the HDMI output revision 2.0 or 1.4a? Thank you all!

Just as the header states, Is the HDMI output on my macbook pro retina 13 inch the 2.0 version or the 1.4a version? Thank you!

I'm asking this because, hdmi 2.0 allows 4K output at 60hz (right?) versus 30hz for HDMI 1.4a. I might connect another 4K display to my mac in the forseable future.

Macbook pro retina hdmi external comes out with a green tint?

I have a 2010 old macbook pro and that works fine but the retina comes out with a green tint when pluged in with hdmi.

I have already tried calibrating the display and i used a thunderbolt to hdmi converter and i had the same problem.

I have tried to display a hd video downloaded from the store on my Samsung hd tv. Message on MacBook pro retina says that display does not support the right type of drm. What's going on here?

Cannot display hd video from MacBook pro via hdmi on my Samsung hg tv. Says wrong type of protection for drm or words to that effect. This is a big pain

Maybe to do with HDCP?

Why does my MacBook Pro Retina screen display pixilated graphics when using the finder?

While this started just after the latest OS X update, each time I use the finder now to locate a graphic to upload, the graphic appears extremely pixelated. It does not matter which application I use to search and upload a graphic file, the graphic appears smaller and bleeds out. I just purchased the new Video Motion Pro video editing software, and every single graphic I upload to this application is pixelated. Has anyone else had any problems with their retina display after the last update?
Here are some examples of hi resolution graphics that now appear pixelated on my Retina screen:

If anyone is aware of an application or Apple software test that allows me to check my graphic card and retina display, please advise. I have performed multiple disk utility checks, restarts, etc., but nothing seems to help.
Any assistance would be greatly appreciated!
Thanks!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.
