Using MacBook Air with plugged charger

Hi,
in the next 2 month I have to work only on my macbook air. I have set it up on my desk directly connected to a second montior. Now my question is should I unplug the charger if the macbook is fully loaded, or should I always connect my charger? What is better for the battery?

You can leave it plugged in for most of the time with no harm done. Apple does recommend using the battery a little every once in a while.

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.

I have purchased (veranda magazines) for my IPHONE which I would like to use on my macbook air. Do I have to repurchase these app or is there some way to get them in my macbook air with no charge?

Veranda Magazine is a free app available for iOS devices in the iOS App Store. You then purchase a Veranda Magazine subscription from within the app. In other words, the app itself is free, but the contents are not.
There is no way to duplicate or import this to a Mac. Your Mac runs a totally different operating system.
iBooks can now import to Mac since OS X Mavericks came out about a month ago. But that does not apply to magazines or iOS Newsstand publications.

Use Macbook Air with external speakers

Does anybody know if the Bose Companion 2 Series III Speakers can be used with an macbook air. If yes, is there any adapter needed or can I just plug the cable of the speakers into the MacBook Air headphone jack?

Naturally yes .. The problem is not the USB itsself, but the fact that original adapters from Apple (LAN and DVI) are made from a Thunderbolt connector, and they do not replicate the port where they are connected to.
Others party LAN adapters that comes on USB port are only 10/100 Mbs, whilst the Apple's one is a Gigabit. This is why I asked for some sort of Thnderbolt hub, or any other experinced advice..
I know that the MacBookAir comes with a good 802.11n integrated wireless, but as you know (or can imagine), when you are in the office a Gigabit connection is another movie, especially if you are tranferring large amount of data or are connected to huge centralized databases.
I was preferring a MacBook Air to the pro for it's monitor: for me a 1440x900 is much more better than a 1280x800 when I'm out of office. On the other hand, the version with the retina display is at the moment too expensive for my budget.
The final solution could be a MacBook pro 15", but I was preferring the 13" when in mobility, for its form-factor.

I've bought a used Macbook Air with no installation drive..

Is there a way I can get a instalation drive living here in Brazil? I really wanted to format this computer cause it's easier than reseting everything from the previous owner. Not to mention that the system would be a little bit faster if I did that and installed only softwares I would really use.
Tks!

Can I use my Macbook Air 13" mid 2013 with plugging charger even at 100 % battery full charge?

I can't decide whether using My Macbook Air 13" mid 2013 with charging power adapter connected even though it is fully charged Or using Macbook Air with unplugging charger after fully charged. Please advice me to maintain my Macbook's battery at good condition.

It will not hurt it as long as you do not leave it on the charger for an extensive period of time (say, days).

Is it OK to charge the Macbook Air with charge for Macbook Pro? 45W to 60W...

Can I charge my Macbook Air with Macbook Pro charger? It is 45W to 60W.
What is impact?

You can use a higher wattage charger than the one that came with the computer, but not one of a lower wattage.

My MacBook Air won't charge using the power cord and it's not the power cord that's malfunctioning. The battery is now exhausted.

My MacBook Air won't charge using the power cord and it's not the power cord that's malfunctioning. I went to Radio Shack and tried two new cords. The battery is now dead. Any thoughts?

Unfortunately, my battery has died as a result of not being able to charge with the power cord. Not sure what an SMC reset is but I have made an appointment to bring my laptop in to the Apple Store. Thank you for your response. Very much appreciated.
Warm Regards,
Carla

When I login to my bank, I get the message: 403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied. Have new MacBook Air with Yosemite. How to solve this problem?

When I try to login to the website of my bank, I get the following error message:
403 - Forbidden: Access is denied.
You do not have permission to view this directory or page using the credentials that you supplied.
I have a new MacBook Air with OS Yosemite installed.
What is the problem and how can I solve it?

Some websites require a special client certficate for access. If you don't have that certficate, you'll have to contact the site operator to find out how to get one.
Sometimes the problem is caused by a web server that is configured to request an optional client certificate. Safari treats the request as mandatory. In that case, other browsers such as Firefox and Chrome may be able to connect to the site, because they ignore the request.
The first time you were prompted for a certificate, you may have clicked through a dialog that requested access to the Apple certificate in your keychain that is used to secure the iMessage service. In that case, you may be able to regain access to the site in Safari by doing as follows.
Back up all data.
Double-click anywhere in the line below on this page to select it:
com.apple.idms.appleid.prd
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the Keychain Access 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 Keychain Access in the icon grid.
Paste into the search field in the Keychain Access window by clicking in it and pressing the key combination command-V. An item may appear in the list of keychain items. The Name will begin with string you searched for, and the Kind will be "certificate."
Delete the item by selecting it and pressing the delete key. It will be recreated automatically the next time you launch the Messages or FaceTime application.
The next time you visit a site that prompts for an optional client certificate, cancel out of the prompt. You may have to do this several times before the server stops asking.

I recently purchase macbook air with OS 10.10.2. I want to use my Seagate external backup plus hard drive for time machine back up. How to partition my 1TB Seagate back up plus hard drive for use with mac and windows pc?

Hi All,
I recently purchased 13" Macbook Air with OS 10.10.2. I want to use my 1TB Seagate backup plus external hard drive as time machine and my windows 7 pc. Please suggest a method. Thanks in advance for your reply.

I strongly recommend having an external drive dedicated solely for TimeMachine. You could partition the drive but if something goes wrong you risk losing the data on both partitions. Should you decide to go ahead with splitting the drive for two different uses you’ll need to partition the drive either using the Mac’s built in Disk Utility program or Windows utility. I believe the built in Windows disk utility program will destroy the current partition and erase the data that’s on it - I use a third party Windows disk utility program for partitioning and it allows for non-destructive partitioning but warns to back up data first just in case. Apple’s Disk Utility can do non-destructive partitions but I don’t recall every trying to do a non-destructive partition on a disk originally formatted for Windows using it. Again - back up that data just in case.
Finally, your TimeMachine drive should be at least 1.5 times (I prefer 2 times) the size of the data you expect to be backing up a year or two from now. In other words, if you currently are using 50GB of your computer’s drive but expect to begin purchasing Mac software to replace software on your Windows computer and if you expect to be putting photos, music, and other data on it you might expect that two years from now you’ll have 100GB of stuff on the drive. So a 200GB partition is the smallest size you’d want. TM’s backup scheme keeps multiple copies of data as it changes so the extra room is important for this scheme.

I ordered my Macbook Air with Aperture two years ago. I now have an iMac - can I use that with Aperture in any way?

I ordered my Macbook Air with Aperture two years ago. I now have an iMac - can I use that with Aperture in any way? I appreciate that it is a different computer but I am now the end user of both devices and I was just wondering if it was possible.
Thanks,
Sean

The answer would be in your software license agreement for Aperture. However if you cannot locate it you can ask in the Aperture forum, the link for that is:
https://discussions.apple.com/community/professional_applications/aperture
However I believe you can have Aperture installed on two machines however only one may be using it at a time.
On the new iMac launch the Mac App Store - Purchased - look for Aperture and download to your new machine.

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.

Can I use a power cord from a Macbook air with a Macbook?

Can I use a power cord from a Macbook air with a Macbook?

No, the MacBook Air power adapter is a 45 watt. A MacBook needs at least a 60 watt power adapter although you can use a MacBook Pro 85 watt adapter. You can use a higher wattage adapter without any problems.
