How to clean Macbook Pro with retina display fans?

So, i'm wondering how you would clean the fans on the new Mac I mean I wouldn't want to blow in compressed air and ruin some components in there(my fans aren't dusty) I just wanted to know i'm curious about it! Since the fans on this mac don't have directs paths of where the air will flow, since in the commercial it says they made them so air would flow all inside the system.

Well, you can check the iFixit teardown of rMBP:
http://www.ifixit.com/Teardown/MacBook-Pro-15-Inch-Retina-Display-Mid-2012-Teard own/9462/1
I would not recommend doing this though as you would obviously lose your warranty. If it actually runs hot, make an appointment and take it to Apple Store. Tell them it is too hot and they will run some tests.

How to format MacBook Pro

I tried to updrage my MacBook Pro while it was connected to the power charger, but the screen suddenly went blank and when I try to restart I get weird error messages and it won't restart. How can I reboot it or format it if necessary?

Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

Is That I need buy any CD or what?

Erase and Install Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.

How to recalibrate Macbook Pro 15" Retina Battery?

I am at my wit's end with this battery indicator! I just exchanged my macbook pro 15" (mid 2014) for a new one due to the faulty speakers and now I am having issues with my battery indicator! I just recently upgraded to Yosemite and all of a sudden my login battery indicator isn't the same as the one on my desktop. After I restarted or shut down my laptop, upon logging in, I saw that my battery was at 94%. Then after logging in my battery is at 100% (without plugging in my power adapter).
Now plugging in my charger made it all weird. At 96% (login page) my battery indicator jumped to 100% and when I logged in it stayed there. I don't know if it's my battery because this is fairly new.
I also try to use coconutBattery and got the same result as the login page indicator. It's quite frustrating as to know if my battery will run out at 10% or not without the coconutBattery app.
Does anyone have this issue as well? or am I the only one?
If anyone has this problem, does anyone know why this is happening?
My battery now is at 100% but CCB says it's 95.5%. It's very frustrating.
Should I just go back to PC world and get this exchange again??
UPDATE: I did PRAM, SMC and even reinstalled and erased disk utility but only got as far as a 2% discrepancy. Seriously I'm beginning to get very frustrated

rljtiam,
I don't know if this will help you any but I noticed that I experience the same issue on my Macbook Pro 13 inch with the battery percent being different at the login screen then compared to after I've logged in. But only when FileVault is turned on. When I have FileVault turned off the battery estimate at the login screen seems to work the same as when I'm logged it. And to make things even more strange it seems to only relate to the initial login. If after I've logged in then log out the login screen displays the same battery percent as when I'm logged in.
I noticed other little things at initial login when FileVault is turn on too. Such as no backlight on the keyboard or not being able to adjust any settings using the function keys on the keyboard.
You can see if you have FileVault turned on by going to:
System Preferences > Security and Privacy > FileVault ( Tab )
Now I'm not suggesting you turn FileVault off if it is indeed enable. I just wanted to point out that I've come across something similar and believe that FileVault is the culprit. Possible in the way it secures the system.
As for any other battery troubles your are having I'm Sorry. I don't have much experience in such and I might do as Kappy and Ralph have suggested.
Also If your interested I might send Apple some feedback. You can do so using the following links:
Related to Mac OS: https://www.apple.com/feedback/macosx.html or
Related to Macbook Pro: https://www.apple.com/feedback/macbookpro.html
I wish you the best of luck,
Weston
Sorry if I was confusing and rambling or if you feel it doesn't help and or relate.

How does the MacBook Pro with Retina display scaled resolutions work?

How does it work? I think I have the basics figured out; is this correct (by this, I mean below)?
It is a scaled resolution (1/2 I think of the actual display resolution) therefore, the size of the pixels would be equivalent to 1440 x 900, but each pixel that is represented on screen is actually 4 pixels, therefore making it look sharper, so things are physically the same size if it would be an actual 1440 x 900 screen, but it looks sharper on the Retina display because each pixel is actually 4 pixels?
Thanks

If you read the specs on them you will discover that the MBP is way more powerful then the MBA. The big feature of the MBA is light weight. If you need a powerful computer then you want the MBP instead.

How can i copy files from one external hard disk to another using macbook pro with retina display

How can i copy files from one external hard drive to another using macbook pro with retina display?

That's odd - if you open Disk Utility (Applications->Utilities) and select the disk(s), how are they formatted? If you're only going to be used with your Mac, they should be formatted as "Mac OS Extended (Journaled)".

Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
        the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.

Be sure you disable or turn off iCloud. Deauthorize the computer in iTunes. Remove any Firmware Passwords you may have configured. Turn off FileVault if enabled.

HOW DO I FIND THE EJECT BUTTON ON MACBOOK PRO WITH RETINA

i have a macbook pro with retina display , and i want to know how i eject the disc from the apple external optical drive i can't see the eject button on the keyboard layout.

It's not a matter of failure, it's the idea of training people to associate the Trash with unmounting a volume. The Trash is a mechanism for the permanent deletion of your data, and designed to appear as such. Apple haters used to laugh at this..."Eject by dragging to the Trash? And you say the Mac is intuitive? Ha ha ha..." And they were right. It's better to teach ways that actually make more sense.
The great thing about all the newer ways is that they are easily discoverable, you don't have to remember or figure out that you have to virtually trash your disk. A new user would naturally expect to find an Eject command or button, and there they are in plain sight.

I always find a ton of mounted installers left behind by users who install stuff on their systems. I don't understand why Apple cannot make an automated process to unmount the installer once it's done. Just seems stupid to me I guess. I've seen that mounted installer confuse people into clicking on it each and every time they want to start the app because they don't understand that once it's installed, that installer should be ejected because they're done with it.
I agree about the installer volume behavior...and Apple made it worse in Mountain Lion by putting the volumes on the bottom of the Finder sidebar, which is often out of view. Incidentally, drag-to-trash does not seem to work with volumes in the sidebar, but the other Eject methods do.
The "installer problem" is another reason I love the other methods much more than dragging to the trash. To eject multiple volumes by selecting them and pressing Command-E is much faster than the time taken to gather them up with the mouse and drag all of them to a specific spatial target.

How do I connect an external microphone to a Macbook Pro with Retina display ?

How do I connect an external microphone to a Macbook Pro with Retina display ?
Alternatively how do I connect an audio input at a level that would normally have gone into a 'line input' socket ?

Plug it into the linein/headphone jack if there's just one. It'll switch between the two modes automatically depending on what you plug into it.

How often should I charge my new macbook pro with retina display?

hi everybody! I just got my macbook today and I want to take good care of it so it lasts me a while, and I'm particularly concerned about the battery life. what ensures that I can maintain a battery that will drain the slowest? or in other words, what are healthy charging habits? I'm a student so I'll be using it more than a few hours daily. should I turn off my macbook or set it to sleep when I'm going to sleep for the night (~6 hours). is there ever a time when sleep is preferable to shut down? when I'm using it for an extended period of time, is it better to run it down and charge it or to leave it charging at 100%? how often should I run down the battery, or if not, what level should I run it down to before charging it again? I read somewhere that it's best to charge it to 80% instead of 100%, is there any truth to this? any input is appreciated, thanks.

How to Install Windows 8.1 on MacBook Pro with Retina Display Using Boot Camp?

Hello,
I own a MacBook Pro with Retina Display and was wondering how do I install Windows 8.1 without an optical disc drive? I have bought the full version of Windows 8.1 and would like to partition it on my MacBook Pro. Could someone please help me out by posting step-by-step procedure or a video on how to do it? It is my first time partitioning the Windows operating system and would like to clarify with the community on this before I install it.
Thanks in advance for those who have helped!

Windows 8.1 is not yet supported by Boot Camp. The best way currently to install Windows 8.1 is to use a virtual machine like Parallels, Fusion, or VirtualBox. Installation instructions are on the Parallels, Fusion, and VirtualBox site.
