How to charge my MacBook Pro Retina for the first time?

I just bought a brand new MacBook Pro 15inch 2.7ghz 16GB RAM model. I want to know how am I supposed to charge the laptop for the first time & plus charging cycles as I continue to use it later on? I've had bad experiences with the iP
There's mixed responses upon Googling the question, some say let it drain completely with others say to charge it when the battery reaches between 25%-5%. Currently my battery charge is at 33% and I haven't used it much either, say maximum an hour's usage in the past 6hours or so from the time I received it and it has not been on standby except for an hour, the remaining time, it was switched off completely. HELP.

Interesting, looking at this page from Apple http://www.apple.com/batteries/ and then following the links at the bottom for each device (notebook, iPod, iPad, iPhone) Apple seems to be recommending one deep cycle a month, that is a discharge to 0 and then a full charge.
For example from the iPhone page:
Use iPhone Regularly
For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).
So is Apple wrong here, or are they using different technology?

    I clicked on iMessage on my Macbook Pro today for the first time, and now NOTES keeps opening up every 5 seconds, with a new note.  I cannot stop it from opening. If I close it or force close, it opens again in 5 seconds.  I can't get rid of it.  I have tried to clear out the iMessage settings I had put in, and I've tried to adjust the Accounts to not include notes to synch.  But, Notes will not stop.  It opens a new note, and even if you ignore it, it assumes preference every 5 seconds, and the Mac is impossible to use.

    Do you have any Boot Camp or other secondary partitions set up on your system? If so then try running a disk verification routine (chkdsk, etc.) in Windows to repair the disk. While I've not heard of it happening recently, in the past errors in these partitions have resulted in stubborn ghost files appearing in OS X.

  • I have bought a Macbook Pro Retina, and the iPhoto which comes with it, has a different iPhoto Book menu.  I cannot see how to put text at the bottom of the pages of photographs, instead of the default place in the middle.  Is there a way to do this?

    There are different templates for iPhoto books and they differ from version of iPhoto to iPhoto, so explore the other options.

    I'm using a macbook pro, running snow leopard. Yesterday I got around to emptying my trash for the first time in quite awhile and was surprised by how much there seemed to be in there. Immediately after a question mark symbol appeared on all my hard disk folders. If I click on these question marks I get a message saying ' the item can't be found'.

    Not sure where these hard disk folders are located that you are referring to?  Finder, Finder tool bar, Finder side bar, Desktop, Dock? 
    More then likely they are  an alias that not longer point to the orginals,  thus the question mark.
    I would reboot.  Delete icons if an alias and just recreate by dragging from the source. Try right click (control) click to remove.

  • My Mail app opens unprompted everytime i reboot or awake my macbook pro from sleep.  This was not an issue until i shut down my laptop for the first time in a while 2 days ago.  ANy ideas how to stop this?

    I recently shut down my MacBook Pro for the first time in a long time.  SInce then, everytime i reboot or awake my laptop from sleep, the Mail app opens unprompted causing my computer to slow down incredibly, and some apps to freeze.  I have no idea how to stop this or why it even started doing this.  Any ideas on how to get it to stop? Thanks!

    I have this problem too with my Macbook Air. Mail opens automatically every time my laptop sleeps. I actually just asked about this in my own thread. However, it is not causing my apps to freeze.

  • I own a 13-inch MacBook Pro and for the past day, my wifi on my laptop says I only have two bars of connection and is running very slow,but all of my other devices such as my iPhone and iPad are connecting perfectly to the wifi. How can I fix this? Thanks

    I own a 13-inch MacBook Pro and for the past day, my wifi on my laptop says I only have two bars of connection and is running very slow,but all of my other devices such as my iPhone and iPad are connecting perfectly to the wifi. How can I fix this? I have tried to shut my laptop off and let it rest and I have also re-started my wifi router three different times. Someone please help me with this problem so I can begin to use my laptop again as I take it to school and use it for class.
    Thanks so much!

    FCP, and all software on OSX, has a few different "preference" files (the extension is .plist), which store all your user settings. Each time you resize a window, change a setting, anything, this file is re-written. Kinda easy to see how they would become corrupt every now and then.
    -Close FCP
    -Navigate to User>Library>Preferences and delete com.apple.FinalCutPro.plist
    -Navigate to User>Library>Preferences>Final Cut Pro User Data and delete Final Cut Pro 5.0 Prefs
    -Empty your trash
    Relaunch FCP and see if that worked.
    Download FCP Rescue to make this process easier in the future. When you have FCP running really smooth, open FCP Rescue and create a backup of your preference files. If it starts acting wanky, just run FCP Rescue and Restore your backup preferences. Works really slick, and it's free.
    EDIT: Or use the really simple explaination that X posted as I was typing.

    1) Copy all music files to a thumb drive / external hard drive.
    2) Open iTunes on your MacBook Pro (congrats!)
    3) Under the File Menu, select "Add to Library."  Navigate to the folder with your music in it and click "Open."  Bam!  Music.

  • Buying a Macbook pro for the first time and i need your opinion

    Hello everyone! I'm buying a Macbook pro for the first time and i need your opinion. I'm a Web Developer / Graphic Designer, and i need this macbook for my work. Currently i have these 2 options:
    1) Macbook Pro with Retina (13")
    128GB SSD, 2.5GHz Intel i5 Processor, 8GB Ram
    2) Macbook Pro i7 (15")
    Intel  i7 2.6 Processor, 8GB Ram, 750GB HD
    So my dilema is. Do i go for the newest 13" Macbook Pro Retina & SSD drive or do i go for the 15" Macbook Pro i7 non-Retina, non-SSD hard drive?

    Your 2nd choice

    is user upgradable. The Retina is not. 
    No matter what for your needs I would max out the 16GB of RAM

    When I open my MacBook Pro for the first time each day, I find condensation on the glass.  What can I do to prevent the condensation?

    This thread and all the followups are hilarious, if it weren't such a serious problem. OP, you may want to add a bit more information on how this drippy screen problem occurs: where do you live, what are the weather conditions, what are you doing with the Mac when it occurs, etc.
    Yes, extreme moisture, to the extent of causing visible condensation, is Very Bad News for any electronic device, and more so with one that isn't tropicalized like the Mac. Besides trying to avoid subjecting it to such extreme temperature changes, using some kind of desiccant to absorb close range moisture and avoidint its use until it dried out, I can suggest placing some kind of absorbent material between the display and the keyboard to prevent the moisture on the glass from finding its way into the computer. Like the protective poliethylene foam protector that came with the Mac when new. Or something like RadTech's ScreenSavrz: http://www.radtech.us/Products/NotebookScreenSavrz.aspx
