I just buy a Macbook pro as a new MAC user. I conceren about internal battery life much. So I have one question that for battery life concern, it is better to use Macbook without AC poower in? or using AC power is better?

  • Looking To Buy A MacBook Pro, But Have A Question

    Hello,
    I am looking to purchase a 17” MacBook Pro and was thinking about getting 8 GB of SDRAM on it. My question is would all of the ram be able to be utilized in the system or would it just use up to 4GB of SDRAM. I am wondering about this because this is still a 32 bit system, right?

    With Snow Leopard, it's fully 64-bit (with a couple of minor exceptions), so it will make use of all 8 GB of RAM, if you max out the RAM.

  • I want to buy iPhone 5 but i have one question that is i have just seen a video on youtube showing laser keyboard and holographic display. is it possible in iPhone 5 and if possible then whether this function is available in iPhone 5 or not...!

    Laser keyboard and holographic display

    There were some folks marketing a laser "keyboard" for computers a while ago. It is not beyond the realm of possibiity that somebody made one with a Bluetooth interface that could talk to an iPhone. It might well be beyond the average person's means to pay for it, though.

    No.
    Power Adapter/ cord wattage
    “Power adapters for Intel-based Apple notebooks are available in 45W, 60W, and 85W varieties. Although you should always use the proper wattage adapter for your Apple notebook, you can use an adapter of a higher wattage without issue.”

  • Looking to buy a MacBook, but I have some questions.

    Hey, i'm looking to buy a Macbook for school, but I want to know if I can buy a Macbook without the hard drive or ram. I have a compatable hard drive and ram already, and my dad has a family license for Tiger.
    So... can I buy a Macbook without the RAM/HD/OS? (I can't seem to find an option for that in the store).
    Thanks,
    MIkeB

    Thanks RadE8! My dad bought a MacBook Pro, but then upgraded the HD and the RAM, so i was hoping that I could use the stuff that came with it... Ah well.
    Thanks again,

  • Should I buy a MacBook Pro now (Jan 2012) considering that a refresh of the MacBook Pro line is imminent? I will be buying the most basic 13 inch MBP and its taken me quite sometime to save up (almost a year!)

    I'm not very well off and although I love MacBooks they aren't cheap either, I've been saving up for a long time now and I don't want to regret it if nvidia or ati graphic cards make an appearance in the new macbook pro 13 basics. Advise please!

    While you are waiting for the new models to come out you could of been using the one you bought tomorrow all that time.
    When Dell, HP, Toshiba, Sony, Apple, Whoever comes out with new models they will have different thing in them. Faster lower powered CPUs better graphic faster hard drives or SSDs more memory and maybe a better operating system.
    So why not wait 1-2-3-4 years. By then the thing may even wash your back and feet for you.
    And they wiil be selling at a premium. There is no such thing as a free lunch.

  • MacBook Pro develops new quirks daily that further limit usefulness

    I'm very computer illiterate.  I just purchased a MacBook Pro laptop a few months ago.  I'm recently retired & intended to teach myself how to use the Mac. 
    Specs:  OS X, Version 10.9.5; Processor 2.5 GHz Intel Core 15;  Memory 4 GB 1600 MHz DDR3; 13 inch mid 2012
    I don't know what I've done to it.  I've downloaded a few APPs.  Then I began to notice it getting slower.  Next, when it would first boot up a box popped up that said, "You've entered the wrong password for iCloud. Enter the correct password for (my user name for Apple (help?).  As the days passed more boxes began to pop up asking for other passwords (for email e.g.).  Then it got to where whatever topic i was asking for information on, the sites that came had nothing to do with that topic.  I can only log into one email account.  The other accounts say that I've entered the wrong password. 
    Can anyone help me?  If anyone knows of online course(s), book(s), manual(s), or online videos that can help me learn more about the Mac.  Any advice by chat from you surfers will also be appreciated.
    I have only used it for surfing the web.  I tried to download some books but failed.
    Thank you,
    Zeb

    Back up all data. Open the iCloud preference pane and uncheck the Keychain box. You'll be prompted to delete the local iCloud keychain. Confirm—the data will remain on the servers. Then re-check the box. Follow one of the procedures described in this support article to set up iCloud Keychain on an additional device. Test.

  • Is it worth buying the macbook pro with 256GB compared to that with only 128GB?

    I will mainly be using the laptop for university style dissertations/powerpoints. I'm also a big music and photo lover but I hardly ever download videos. What are everyone's views?
    Kind regards,
    Charlotte

    It is a function of the types of data and how much is generated.  If all one would ever have is text on the MBP, certainly 128 GB of storage may be enough.  If one starts adding pictures, music, video, game applications etc., the equation can change radically.  I venture to say that almost all university students use their computers for personal as well as school activities. 
    If the bank account is tight and additional storage cannot be added, in all probability great discipline will have to be exercised as to what will be kept on the MBP.  If you order a MBP with minimal storage and find you need more, all is not lost because you can purchase, at a reasonable price, an external HDD to take up the slack.   The disadvantage is that you then have another physical item to deal with but a degree of convenience and efficiency is lost.
    Ciao.

  • Why does my Macbook Pro with newest OS completely FREEZE when it comes out of sleep mode?  Need to hard start with power button.  Hating Apple right now.

    Sleep mode.  Open lid.  Nothing.  beach ball forever.  Need to hold power button and hard start EVERY DAY.  This is stupid because I heard of this problem a year or so ago.  Fix???

  • I have one app that when open will not orient. Everything else does.

    How can I get an app to orient? 

    Try these in order.
    1. Quit the app completely and restart the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
    Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
    2. Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
    3. Delete the app and reinstall it. Tap and hold down on the icon until it jiggles and then tap the X on the icon to delete it. Tap the home button to stop the apps from jiggling. Download the app again in the purchased tab of the App Store.
    If you have data or documents in this app, backup your iPad first so that you can restore from a backup in order to recover the data.

  • When would it be wise to buy a macbook pro retina

    i would like to know when would be a good time to buy a macbook pro
    I have one already and was wondering when the newer models will be in stores and perhaps some idea of what chip set along w/ other specs they might be using.
    I like the all flash mem concept and other aspects yet would also like to see the hardware tested by users. if some owns a retina perhaps you could share with me yr. thoughts of it along w/ any rumors and flaws. Are these new macbook pros worth the price and when will newer models be avaliable??

    IMHO Never. To limited even if they fix the current problems with the current units or in a newer version.
    It is a glorified iPad.

  • I'm using Logic 9 with a Macbook Pro. On one project I'm getting a message ' not enough processor power.' I've tried freezing all tracks but this seems to have no effect. I've also bounced all soft synths to audio.

    I'm using Logic 9 with a Macbook Pro. On one project I'm getting a message 'not enough processor power' and the computer stops playing
    I've tried freezing all tracks but this has no effect. I've also bounced all soft synth tracks to audio, but to no avail. The computer stops playing
    even at the start of the track where there is nothing but a kick drum happening.......

    Thank you for the suggestions.
    I had previously tried all of the above but the airport/wireless thought. Unfortuneately, none of these things made a difference, including the wireless suggestion.
    Currently, I am using my Mac's "cheapo" internal audio hardware  (haha). I have a one year old 27-inch iMac,  a good pair of bose speakers, and a polk sub. I don't believe it is an issue with my setup, considering I completely disconnected and unplugged it.
    I did, however, do a little info hunting on the internal audio situation, since I was curious what is actually included, and I stumbled upon this interesting little tidbit about my model of iMac:
    https://discussions.apple.com/thread/2718054?start=0&tstart=0
    I had previously wondered if I was hearing my mouse in my speakers as well (not just in logic). It appears that this model of iMac may have some grounding issues, as someone later in the thread suggested purchasing and using a ground loop isolator, which seemed to fix any extra interference for them.
    Ironically though, I have since opened logic, and do not seem to be encountering my previous static issue(yet).
    Fingers crossed, hoping that I will not be experiencing it again. Going to purchase a ground loop isolator, and continue to mess around with logic, just to make sure it was not just an internal audio issue with my iMac.

  • I'm looking to buy a new Macbook Pro, and have questions about the Applecare extended warranty?

    I'm looking to buy a new Macbook Pro, and have questions about the Applecare extended warranty? I want to know if the 3 year extended warranty covers what damage. Like water damage, accidental damage, lost or stolen macbook, manufactory defects, or any other kind of damage, maybe be even cosmetic damage. Can anyone help me?

    If you are talking about features of the MBP itself, as long as you are not looking at  the Retina models, then the memory you can upgrade yourself for a lot less than Apple charges, and that does not affect the warranty as Apple considers memory a user permitted upgrade.  Great sources are Crucial and OWC, both are Mac specialists and have on-line videos on how to do the install.
    If the 15" is what you are looking at, a good upgrade is the 7200 rpm hard drive, gives a little better performance over the standard 5400 rpm drive.
    The Hi Res screen is good if you do a lot of graphics work.
    Comparing the 13" amd 15" you will notice the 15" has a second, discrete graphic processor...helps when you get into heavy duty videos, games, graphics...but keep in mind that kicking in the second processor uses a lot of power and will run the battery down faster.
    If you are looking at the Retina models, then keep in mind there are no post-purchase upgrade options...you have to buy with everything you want at the start.
    Just some thoughts.
