Hey guys, that can't be (not with a hardware less then 3 month old!!!) I feel like in old PC/ Windows time. Any idea, input what's wrong?

    Unfortunately, as recommended by the lady from CA, as long as the Mac is still associated with the Apple ID of the original owner, you can't even buy those iLife apps with that Mac. You will always get the alert to download them with the original owner's Apple ID.
    As suggested by the chavo from España, you need the original owner to contact Apple Care* and request that the OS and the iLife apps be disassociated from his Apple ID. Then you should be free to OS X Recovery to resinstall the most recent version of OS X that shipped with the Mac and install the iLife apps. Afterward, before using any of the iLife apps you need to open the Mac App Store (MAS) to the Purchases pane and Accept these apps into your MAS account's Apple ID. If you use any of the iLife apps before you have accepted them into your account, as per the app's Terms of Use, they all become one-trick-ponies that can not be downloaded onto another Mac or updated.
    OS X Recovery -

    *If you bought the Mac from a 2nd hand shop and don't have access to the original owner, you may need to provide Apple a purchase receipt to offer proof of sale.

  • Xcode/eclipse C++ on 11" MacBook Air with 2GB RAM, OS X Lion and 64GB SSD?

    Hey, I'm planning on getting a 11" MacBook air with a 2GB RAM, 64GB HDD and OS X Lion. I am also going to get a 500GB external HDD with it and I would just like to know if it would be good to run Xcode or eclipse on it so I can code C++? Please note that I will install Xcode/eclipse to the external HDD If that affects the performance? Thanks.

    I have a MacBook Pro running Lion. I have both XCode and Eclipse. It should work fine.

  • 2010 Macbook Air with 4GB RAM or 2011 Macbook Air with 2GB RAM

    So I am looking a the following 2 Reforebished Macbook Air models:
    Refurbished MacBook Air 1.6GHz dual-core Intel Core i5
    http://store.apple.com/ca/product/FC968LL/A
    Originally released July 2011
    11.6-inch (diagonal) high-resolution LED-backlit glossy widescreen display
    2GB memory
    64GB flash storage
    Thunderbolt port with support for up to 2560-by-1600 resolution
    FaceTime camera
    Intel HD Graphics 3000
    $789
    Refurbished MacBook Air 1.6 GHz Intel Core 2 Duo
    http://store.apple.com/ca/product/G0JK0LL/A
    Originally released October 2010
    11.6-inch LED-backlit glossy widescreen display
    4GB memory
    128GB flash storage
    NVIDIA GeForce 320M graphics
    FaceTime camera
    $799
    So my main question is which is better, the core 2 duo with 4GB of memory and 128GB of storage, or is the intel core i5 with 2GB of memory and 64GB of storage better? There is only a $10 differnce so the price doesnèt matter to me.

    i would go with the one with more RAM and larger SSD.
    Simple reason - you can't upgrade it in the future.
    Sure the other one has a faster processor but what's the use of having a faster processor if you only have 2GB of RAM?
    The other one is newer, but again, you can't upgrade it.
    That's the reason why it's also cheaper........

  • Macbook air more GB RAM

    hey, i recently got a new 11.6" MacBook Air with 2gb ram and i was wondering if it was possible to add 2 more gb of ram ??

    I'd be shocked if anyone would offer to upgrade the RAM on a MacBook Air for you. I don't think you could perform such a successful "upgrade" by hand, I really think you'd need machine precision given what Chris said.
    If you absolutely have to upgrade your RAM then you have two, realistic options:
    Sell the existing machine, use the proceeds to buy a new machine with 4GB of RAM
    Buy a service part logic board for your model with 4GB of RAM, I see them go for about $700-$755.

  • Time Machine backup created on Mac with a large hard disk. What happens when restore to MacBook Air with small SSD drive?

    What if a Time Machine backup was created on a Mac with a large hard disk, e.g. 500GB iMac - and I buy a new MacBook Air with a small SSD hard disk e.g 128GB. What happens when I need to use the larger Time Machine file to set up the new MacBook Air? What happens to all those files that can't fit on the smaller SSD drive?

    It is not the HD size, but rather the size of the data it contains. If you right-click your 500GB drive and select "Get Info" you can see how much is actually being used.
    Naturally if you are using more space than the new drive has, then you have to make some choices about what you want to keep and what you want to keep archived.
    I don't know what options are available but you may simply have to do a manual restore of files you want, in groups.

  • Migrating to new macbook air with Lion, entourage 2008 doesn't work

    I  bought a new macbook air with lion installed. trying to migrate data from my old macbook with snow leopard. Got most data across, and installed my most frequently used applications:
    - office 2008: most office apps 2008 work, if buggily. entourage not, see below.
    - firefox (hangs up when downloading updates)
    - dropbox (ditto)
    <these two problems may have something to do with internet proxy settings, will try to sort that out later>
    MAIN ISSUE:
    entourage wont open at all.  so for now i'm using my old comp for e-mail and the new for the rest.
    MY OPTIONS:
    please advise (1) what you think is the most time & nerve-saving option (2) how to do it smoothly:
    A) try to get office 2008 to work.
    when trying to open entourage, it tells me this version (office 2008 12.0) cannot open this entourage database (12.3)
    error for other apps says there is a problem with database, and rebuilding several times did not fix it.
    would have to start with updating to the version i used last (office 2008 12.3). Problem is the ms office updater does not seem to work on lion. the first update does not open, says it does not support powermac.
    B) buying office 2011, and migrating entourage 2008 to outlook.
    I suppose the best way to do this is to install office 2011 on the old mac first, then on the new one, then move database, right?
    C) migrating from entourage 2008 to lion mail.
    best way to do this would be to import entourage email to leopard mail, then move those files to the new mac?  and move entourage addresses into the mac addressbook. my major concern is that i have a lot of mailing rules, and a fair bunch of notes. a lot. i;d rather not have to recreate those by hand. Is there a way to import rules from entourage to mail?
    i also habe a huge backstock of mail, over 10,000, and a correspondigly huge addressbook (within entourage). i'm ready to abandon entourage at last (though i used it for a decade), but i want to have my addresses, my rules, and at least the last 3 yrs of emails. i get about 130 mails a day so i need plenty of automatic organizing capability.
    i never had issues  my old mac/snow leopard, i just ran out of ram and the one usb broke, so i figured it's time. kinda sorry i did not just get the usb repaired and extra ram. what a hassle these migrations always are.
    cheers!

    Yes, repairing first is a sound idea. In my experience I've only moved from Entourage to the OS X applications or from one version of Entourage to another. In the latter I've been able to just copy over the Microsoft User Data folder. But I have not used Entourage for quite some time.
    Microsoft don't make it quite that easy to migrate to their own applications, but the import from a 'tidy' .rge file works well, I had a lot of issues with the first few I migrated but after performing a database repair prior to import all proceeded smoothly.

  • Where to find the best application for cleaning out my MacBook Air with OS X 10.7.5? I've been using MacKeeper but believe it's slowing down my laptop considerable.

    where to find the best application for cleaning out my MacBook Air with OS X 10.7.5? I've been using MacKeeper but believe it's slowing down my laptop considerable. Thank you.

    How to maintain a Mac
    1. Make redundant backups, keeping at least one off site at all times. One backup is not enough. Don’t back up your backups; make them independent of each other. Don’t rely completely on any single backup method, such as Time Machine. If you get an indication that a backup has failed, don't ignore it.
    2. Keep your software up to date. In the Software Update preference pane, you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis. This is especially important for complex software that modifies the operating system, such as device drivers. Before installing any Apple update, you must check that all such modifications that you use are compatible.
    3. Don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, this stuff is useless, or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.
    The more actively promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam.
    As a rule, the only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Use your computer; don't fuss with it.
    Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception to the above rule. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction.  Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
    Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve.
    4. Beware of trojans. A trojan is malicious software (“malware”) that the user is duped into installing voluntarily. Such attacks were rare on the Mac platform until sometime in 2011, but are now increasingly common, and increasingly dangerous.
    There is some built-in protection against downloading malware, but you can’t rely on it — the attackers are always at least one day ahead of the defense. You can’t rely on third-party protection either. What you can rely on is common-sense awareness — not paranoia, which only makes you more vulnerable.
    Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must be acquired directly from the developer. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from a web page without your having requested it should go straight into the Trash. A website that claims you have a “virus,” or that anything else is wrong with your computer, is rogue.
    In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
    Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.
    5. Don't fill up your boot volume. A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a boot failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem. While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage consumption and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
    If storage space is running low, use a tool such as the free application OmniDiskSweeper to explore your volume and find out what's taking up the most space. Move rarely-used large files to secondary storage.
    6. Relax, don’t do it. Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," "testing the hardware," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
    The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.

  • Problems about the Macbook air with Lion 10.7.2 running Warcraft III

    Hello
    I have bought the newest Macbook air with 128G SSD recently. The system is Lion 10.7.2
    I am wondering why when I entered the Warcraft III game, the buttons and mouse are all black, I can not play the game.
    The newest macbook air is using Intel HD Graphic 3000 as the display card
    Is it possible that the driver on Lion for this display card not compatible with Warcraft III?
    How can I solve this problem?
    Thank you

    Lol, you are both wrong.
    First, yes, the buttons in the main menus are black. This is ****. Wrote that in a Blizzad forum already.
    But: The game is fully playable once you start a game.
    Second: This has nothing to do with PPC. WC3 is Universal! (How would he have known that the buttons are black if he couldn't even open the WC3 app!?!)
    But one thing concerning Universal Binary has to be done by Blizzard: Make the Installers Universal too.Curently, there is no way to install WC3 in Lion.
