Does 2013 macbook air use a special version of OSX 10.8.4?

does 2013 macbook air use a special version of OSX 10.8.4?

Don't know about a 'simple data transfer via USB drive'........
Have to make sure 3rd party software (like MS Office 2008 and CleanMyMac 2, etc) make the trip over to the new Macbook Air. Also, my current MacBook Pro does not have USB 3 and that would make a connect slow, very slow.  Best bet I think is a Firewire 800 to Thunderbolt connect.
Sadly, this is turning out to be 'like two ships passing in the night' in that OSX 10.8.5 is due out 'soon, very soon' and it reportedly will include drivers, etc that make this issue moot.  However, as they say, 'it's my money and I want it now!' , so I won't wait and will settle for 4/5 of the loaf.
Thanks for your help!

  • Does the Macbook Air run full, standalone versions of software or does it require special, streamlined apps?

    I'm looking to buy a Macbook. Will the Macbook Air load and run full, unabridged versions of Mac-compatible software, such as what I already own, or does it require only special "apps" versions such as the iPad and iPhone do? I realize that the Macbook Air blurb states you can wirelessly use another Mac's drive to load software onto a MBA or buy an add-on drive to connect it up and load software but my question is the performance capability of the MBA to actually run full versions of ALL OS X Mac-compatible software.

    The MacBook Air runs the identical operating system as any other Mac, and is subject to no arbitrary limitations imposed on the latest software, or by the latest software.
    The only remaining factor is hardware. All Mac software has it's own individual requirements for the system, that being the speed of the processor, the amount of memory, the type of graphics processor required, etc. Some select software, say intense game apps, will not run very well or at all on the MBA, and it simply the lack of a system's component compatibility of performance. But this is a factor present in all computers, nothing special about the MacBook Air.
    So, as long as the hardware is sufficient for the system requirements of the software, you can install and use any full version app designed for OS X Lion.

  • How much electricity does a Macbook Air use?

    I'm moving out and living on my own for the first time. It'll also be the first time I have to pay utility bills. I was wondering how much electricty a Macbook Air (2011) uses during use, sleep, and charging. I'm a college student so I don't have a lot of disposable income so I want to save as much as possible. If I remember correctly, my desktop computer used to shut down every time I opened iTunes when it would work just find when I did other things. Does that mean iTunes uses a lot of energy to operate?
    Anyways, I'm wondering if the usage of electricity is high for Macbook Air (2011) and whether I need to charge up my laptop at the nearest starbucks or library.
    Thanks in advance.

    It uses very little power,  cents/month.  In any case the power adapter is 45watts so the max it could use would be equivelant to leaving a 45w light on all the time.  Reality is much much less.

  • Use 21.5 inch mid 2010 imac as a display for 2013 macbook air?

    I would like to use my 21.5 inch mid 2010 imac as a display for my 2013 macbook air. I tried using Screen Recycle, however I would prefer more of a monitor situation than a side-by-side extra screen situation. Ideally with my wireless keyboard and mouse. Does anyone have any advice, or am I asking too much from apple? Thanks very much.

    Yes. With an Ethernet cable and a product such as ScreenRecycler.

  • When i use my infocus portable projector, the trackpad on my mid 2013 macbook air completely stops working.

    i have the new 2013 macbook air and like i stated above, the trackpad on the macbook completely stops working. i cant use it to navigate which forces me to use a wireless mouse to be able to navigate at all. i was wondering why this happens and if there any soulution. the projector is plugged in through usb and im not sure if that might be the problem ?

    I wouldn't expect a projector to affect the trackpad like that. Possibly if you go into System Preferences -> Accessibility -> Mouse & Trackpad and uncheck Ignore trackpad when mouse or wireless trackpad is present.

  • Does my macbook air have a built in virus scan?  how can I access and use it? also any recommendations of what software if this is not avail ?

    does my macbook air have a built in virus scan?  how can I access and use it? also any recommendations of what software if this is not avail ?

    Contrary to what Geeks on Hugs is telling you, Mac OS X does indeed have a basic malware scanner. It is not a feature that is directly accessible to the user, and works a bit differently than every other malware scanner out there. Gatekeeper, which has been mentioned here, is entirely separate, and provides a different method for helping to protect you against malware.
    The anti-malware scanner in Mac OS X is called XProtect. When you download an application (or any other kind of executable code), it is automatically "quarantined," so that when you open it you're asked if you really want to do that. I'm sure you're very familiar with this aspect of Mac OS X if you have ever downloaded any apps from outside the App Store. What you don't know, though, is that each time you try to open a new app, that app is checked by XProtect. If it is identified as malware, you will not be allowed to open it, and will be warned that it's malware.
    At this time, there is no known malware that can infect a properly up-to-date Mac. All current malware will be blocked by one or more methods.
    For more information, see my Mac Malware Guide.

  • If you get a new 2013 macbook air does the laptop come with os x mountain lion?

    I have a new 2013 MacBook Air and i was wondering if my laptop came with OS X Mountain Lion????

    It should. To check click the Apple logo in the menu bar (top left) and select "About This Mac"
    If the OS X version shows 10.8 then you have Mountain Lion.
    If you don't have the Mac yet then the new one you buy will have Mountain Lion on it.

  • Does the macbook air get hot from use?

    I am considering purchasing a Macbook Air.  I have had problems with notebook PC's in the past getting very hot.
    Does the Macbook Air get hot from use?

    Yes, well, virtually every computer has a fan in it; many fail their mission.
    Now that you mention it, I saw no grill or mesh anywhere when I looked at the MBA at the Apple Store.  Is it where the lid meets the body?  I didn't see speakers, either, although I heard music.

  • I have a MacBook Air using Maverick. I have files in the trash I want to recover. I do not have "Put Back" and Command   Delete does not work.

    I have a MacBook Air using Maverick. I have files in the trash I want to recover to their original files. I do not have "Back Up" and "Command + Delete" does not work.

    Drag them out of the Trash and put them in their original location. Put Back may work on one file at a time.

  • Does the new (2013) macbook air have the same structure and size as the original?

    I just recently purchased the new 2013 13" macbook air and was looking into getting a case. Wanted to know if i need a different case for the 2013 macbook air? Please respond ASAP!!

    Actually... if by "original".... you actually mean "original", the answer would be no.  The original Air was released in 2008 and has a significantly different format than the second generation:

  • Massive Battery Drain After Mavericks Upgrade on 11" 2013 MacBook Air?

    I got my Air about month before Mavericks came out and the battery life was amazing on it. I was easily getting 14-10 hours of life using Chrome and Air Mail App, along with Power Point and MS Word. After the upgrade to Mavericks, it was slow but I started to notice that my battery life during classes was draining so much faster than before and I had not added anything 3rd party software, just the upgrade. I am now down to about 3.5 - 4.5 hours of battery life doing about the same things as before the upgrade. I did a couple of apps and I added (Sims 3 game). However, I have yet to touch it because of the diminished battery life.
    I have included a copy of my Etrecheck, can somone take a look and let me know if you think I need to clean something off?
    I did do the SMC reset and that seemed to to give a little juice (like putting new tire on your car but still not where it was before the Mavericks upgrade) as I am up to about 6 hours of battery life after the SMC reset.
    Please let me know what other information you might need from me that would help and thank you so much!!

    Hi Lex,
    Not sure why but I had a hard time finding all of the related files to get rid of Origin. But I think I finally got them. I just uninstalled Flash and Chrome. I don't like Safari but all well. I suppose I can deal with it it until Apple fixes this battery issue and then maybe I can go back to Chrome. Safari isn't too happy with certain websites, under the Preferences/Security there is an error message that reads "Google Safe Browsing Service Is Not Available. Has not been updated in 8 days."
    Haven't noticed a change in battery since doing all of this so let me know if it will take a couple of days to reset. Or if you see anything else that I can do to help. Thank!

  • Mid 2013 macbook air: battery drain / running hot

    Hi there,
    For the last couple weeks my MBA starts to run hot and drain battery fast if I've been using it for a few hours.
    I use it a lot on most days and connect to powercord only once it drops down low, like below 20%.
    Have just seen other posts who recommend doing that at 50% battery and will now do the same.
    However my question is: have i ruined my battery in the meantime?
    AND/OR is there something else i can do to get battery running like it used to, and stop the loud fan switching on all the time because it's all running too hot?
    I've copied in an etrecheck in case that helps diagnose more....
    thanks heaps for any help!

    1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem.
    2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
    Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a few minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
    4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
    5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
    6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

    Copy the selected text to the Clipboard by pressing the key combination command-C.
    7. Launch the built-in Terminal 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 Terminal in the icon grid.
    Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
    8. If you see an error message in the Terminal window such as "syntax error," enter
    exec bash
    and press return. Then paste the script again.
    9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
    If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
    10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
    [Process completed]
    to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
    11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
    If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
    12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
    Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

  • Improving the 2013 Macbook Air i7 battery life

    Hi
    I've checked couple of topics related to this issue seems many people suffer from this problem, i7 8gb ram with 512gb ssd Macbook air has some issues with its battery life it reduced very quickly. I've applied some techniques -like smc reset,deleting launch daemons and agents- and have an improvement in battery performance. Now the point is, when i do the EtreCheck there are many kernel extensions displayed in the report. Is there any way to delete them and slightly improve the battery life?
    Here is the output:

    Is there any other suggestions that you may offer ? Many thanks

    You can use the new Activity Monitor to determine a unitless "Energy Impact" value:
    You can also click the battery icon in your Mac's menu to reveal significant energy hogs (UPS is shown below):
    Whereas Apple recently updated their apps to take advantage of Mavericks' energy saving algorithms, few other vendors have. I surmise the prominent "Energy Impact" hall of shame addition to the new Activity Monitor is Apple's subtle way of nudging them into compliance.
    Google's plethora of invasive OS X system modifications is a popular reason for excessive battery drain. Google has yet to demonstrate the ability to develop efficient OS X apps, and one can only surmise they are not interested in doing so. If you elect to use Google Chrome or any other poorly implemented OS X programs, you must accept the detrimental effect they will have on performance and battery life.
    If you no longer use a Blackberry, uninstall RIM's software. Be sure to follow its uninstallation instructions.
