Why does the MacBook Retina 15" do software scaling to the native resolution of 2880x1800?

OS X does not allow changing the viewport resolution to the native 2880x1800, and it suggests 1440x900 as a retina optimized one. This means that software scaling is done on the fly. My question is, why?
I have two suspicions:
1. Running everything at the native resolution puts a bigger strain on the GPU, hence slowing down the OS, putting down battery time.
2. The number of apps using retina-ready sprites is miniscule, hence Apple does not want to mess with the user experience. Although I doubt it, as software post-processing is done even now, and apps with non-retina sprites look slightly blurred. If the native resolution would have been used, they would just look a bit more blurry.
Just some comments:
1. Switching to the native resolution will make everything smaller, up to the point of not being usable. But this is a non-argument, as the OS could be smart enough to use bigger versions of the sprites/icons/text. Apple already demands that developers use hi-res sprites (OS X Human Interface Guidelines), hence everything could be scaled x2 and it would be the same size at 2880x1800, as it is at 1440x900 in the current version of the OS.
2. Technically it is possible, as outlined here: Running the Retina MacBook Pro at Full 2880x1800 Resolution. Have a look at the comments too, there are some interesting observations in line with this question, but no definite answers.
3. I am aware that the OS X Cocoa server is running at native resolution at all times. This question is concerned with the viewport resolution, which requires hacks to be set to the native one.
Can answer on Quora if preferred (http://www.quora.com/OS-X/Why-does-the-MacBook-Retina-15-do-software-scaling-to- the-native-resolution-of-2880x1800)

Ah right at the top.

This is a common problem with new Mac notebooks. There arre many threads on this and other forums about it.
Tae your Mac to an Apple store to be fixed or replaced.

  • Why does my iPad 2 not list software updates in the settings?

    My iPad 2 does not give an option for software updates in the general settings.

    Because it's running an iOS version prior to 5.0. The next update needs to be installed from iTunes on a computer, and if possible, the one the device normally syncs with.

    According to the article (http://support.apple.com/kb/HT1237), the latest SMC version of MacBook Air should be 1.73f65 (SMC 1.6). However, I found the SMC version is 1.74f3, which should be MacBook Air (13-inch)'s.

    Thanks, that seemed to work. But now I've been having a new issue lately. I'm starting to think its hardware related, but either way I've had many crashes...some not always with a crash report. It seems my SMC is acting up at times, and other times the screen will glitch out and produce these pixelated horizontal bars and then crash. I just reinstalled OS X, I've run the usual diagnostics. I'm getting ready to run a Apple Hardware Test, but I figured I'd come to you for help first.
    Here's the most recent crash that occurred (no horizontal bars this time), but it did crash and refuse to restart (it beeps the strange tone from what seems like a spot other than the speaker, that's how I came across the system management controller reset). Anyway, here's the report:

  • Why does my MacBook Pro fan go into overdrive when the laptop is not even warm?

    The fan on my MacBook Pro is going into overdrive without any form of heat coming from the laptop. It causes the computer to be really slow as though there's a delay on the cursor, then makes it crash. It also disconnects me from the internet and won't reconnect without a restart. Had this trouble for a few months but it stopped for roughly four months without giving any clue as to what I had done to stop it, but has now restarted again out of nowhere.
    I have tried an SMC reset countless times and it makes no difference. Operating system is up to date.

    Either on Microsoft word or on FB and maybe some online editiing.. I have installed Istat and waiting for it to occur again so i can measure the heat and CPU usage.. any idea as to why this is happening??

  • Why Does my macbook pro fan suddenly heat up making the fan work on overdrive and my entire mac lag?

    Hi there I have a macbook pro 2.4 G 13", Its been running like a beauty with absolutley no trouble at all.. as of late however i ve noticed an unsual fan sound and also lots of heat coming from the vents at the back, also when this happens i ve noticed that the mac starts lag which is extremely strange.. I ve seen quite  few ppl post this problem but still have not found a solution. Please Help

    Either on Microsoft word or on FB and maybe some online editiing.. I have installed Istat and waiting for it to occur again so i can measure the heat and CPU usage.. any idea as to why this is happening??

  • Why does my MacBook pro keep beeping 3 times. The screen is frozen.

    Like my MacBook Pro keeps beeping 3 times and pausing for 2 seconds. The screen is frozen.  How do I fix this and what is going on?

    That is  a RAM issue, do you have any spare ram you can swap to confirm?  Possible causes:
    a ram module going bad
    installation of incompatible ram
    your ram may have become dislodged
    I would suggest:
    - removing all ram from your MBP, and reinstall it to see if that helps.
    - if you recently installed new ram, remove it, then restart the computer with  the old ram to see if this helps.

  • Why does my MacBook hang? It's boring watching the colour wheel spin endlessly.

    My wife and I have matching MacBooks. We are having problems with system hangs. These occur mostly when working in the finder. The system hangs when using scrollbars, clicking on files to open an app, using command tab to scroll through apps, opening new finder windows etc. These problems havebecome so bad that I am considering buying a windows laptop because we can't get any work done. We've tried Disk Utilities, Disk Warrior, MacKeeper, System reinstalls zapping the PRam etc. Nothing really helps. We did find a couple of files infected with windows trojans but even after deleting them the problems continue.
    I've read in a few posts about overheating causing these problems and tried installing smcFanControl, but it would not launch after installation.
    After being a Mac addict since my 7100 I am now considering going to windows I am so ****** with this MacBook.

    Well, MacKeeper can inflict damage to your system:
    MacKeeper is highly invasive malware that can de-stablize your operating system. It is also unethically marketed and a rip-off.
    Further opinion on it and how to uninstall MacKeeper malware:

  • Why Does My Macbook Retina Keep Shutting Down and Restarting?

    Here is the error I got last time. I'm in the middle of finals and can't really afford to lose this computer for another 4 days. What should I do?
    Sometimes the screen just black and I can hear noises when I turn the volume up and down. Then I close the computer and it restarts.

  • Why does my macbook pro retina display shutdown while entering the administer account

    why does my macbook pro retina display shutdown while entering the administer account

    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.

  • I am going to buy myself a MacBook Pro in the near future and was wondering if the new Retina Display model would be worth the extra cash. I will mostly be doing photo/video/music editing.

    I am going to buy myself a MacBook Pro in the near future and was wondering if the new Retina Display model would be worth the extra cash. I will mostly be doing photo/video/music editing.

    if you're not in a big rush - why not hold off until Adobe and Microsoft releases an update to support the Retina Screen.
    Don't get me wrong - the Macbook Retina is a good and videos look great - but when it comes to Photoshop, it's a little blurry and the fonts in Excel and Word is pretty blurry too.....I own one....
    In any event, if it's something you can live with - then by all means - go for it.....
    Otherwise - get the non Retina Macbook Pro - it's cheaper, and it's user upgradeable in both RAM and Hard Drive.
    Good luck.

  • Why does my macbook pro stop loading the webpage every time i try to access netflix or youtube?

    Why does my macbook pro stop loading the webpage (in safari) every time I try to access netflix or youtube?

    Back up all data before proceeding.
    This procedure will unlock all your user files (not system files) and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
    Step 1
    If you have more than one user, and the one in question is not an administrator, then go to Step 2.
    Triple-click anywhere in the following line on this page to select it:
    sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
    Copy the selected text to the Clipboard by pressing the key combination command-C.
    Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
    You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
    The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
    Step 2 (optional)
    Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
    Start up in Recovery mode. When the OS X Utilities screen appears, select
              Utilities ▹ Terminal
    from the menu bar. A Terminal window will open. In that window, type this:
    res
    Press the tab key. The partial command you typed will automatically be completed to this:
    resetpassword
    Press return. A Reset Password window will open. You’re not going to reset a password.
    Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
    Select your username from the menu labeled Select the user account if not already selected.
    Under Reset Home Directory Permissions and ACLs, click the Reset button.
    Select
               ▹ Restart
    from the menu bar.

  • Why is my Macbook Pro running slow after I downloaded the new Lion software? I have a 2.26 GHz intel core 2 duo? whats Wrong?

    Why is my Macbook Pro running slow after I downloaded the new Lion software? I have a 2.26 GHz intel core 2 duo? whats Wrong?

    Spotlight may be indexing your drive(s).  Click the Spotlight icon at the right of your menubar; if it shows things being indexed, that's at least some of the reason. 

  • Why does my Macbook not choose the 5Ghz network?

    Hi there! Can anyone tell me why, if I have a dual band simultaneous Airport Extreme and iStumbler says I have a 58% 5 bar 5Ghz on channel 100 signal right at the top of the list of available networks and the other examples from my network are 45% and 42% on the 2.4Ghz band - then why does my Macbook insist on choosing one of the lesser signal strength networks to log in to? I am extending my network via an Airport Express in the bedroom and I think it is that which is showing the highest signal (probably as it it considerably closer than the Extreme where I am sat right now!). Just wondered, doesn't seem very dual band to me if it never connects to the better band? Don't want to force it to connect to 5Ghz as that's not required, at the moment it chooses.

    Chances are that the extended network is using the 2.4 GHz radio band as this band allows for greater range. Remember that the AirPort Express can only operate in one band or the other. It is not a simultaneously dual-band device like your Extreme.

    Why does my macbook give me the option to choose Macintosh HD or recovery HD at startup every time?
    It never used to do that before until now.  How can I get it to just start up to the regular Macintosh HD again without clicking on the HD at startup?
    Im running a new macbook pro 13 inch with lion and everything is fully updated. 
    Thanks.
