Which should I pick? A 2012 Macbook Air with 8GB of RAM, or a 2013 Macbook Air with 4GB of RAM?

My mother bought herself a new computer, and she is letting me choose which one will go to my sister: my 2012 Macbook Air, or her 2013 Macbook Air. My sister does not care at all about performance, but I definitely do. Which would be better to take? Keep in mind, I do like to run video games, and still would like optimal speed for things like running various programs, Specs below.
2013 Macbook Air:
Intel Core i5-4250U @ 1.30 GHz
4GB 1600 MHz DDR3
Intel HD Graphics 5000
2012 Macbook Air:
Intel Core i5-3427U @ 1.80 GHz
8GB 1600 MHz DDR3
Intel HD Graphics 4000

Both computers you are looking at use Intel's integrated video and unless you are going to be compiling a massive program you won't notice a significant difference between the two machines. You'll want 8GB RAM for sure and I strongly recommend the 256GB drive rather than the 128GB drive. You don't fully realize how small a 128GB drive is until you find it full and think "But I hardly have anything on it!"
I found that using a second display has very helpful though today an iPad could fill in for the second display. I liked to have documentation, lab notes, or a Web site open in one screen with the IDE open in the other. That was easier than flipping back and forth between windows.

  • 15"Macbook Pro fall 2011 with Core i7 2.0 GHZ, 8GB RAM v/s 2013 Macbook Air 13". Is it a good upgrade?

    HI All
    This is my first post here. As mentioned I have a fall 2011 15"Macbook Pro fall 2011 with Core i7 2.0 GHZ, 8GB RAM and i was thinking of buying a 2013 Macbook Air 13". Is it a good upgrade? I do light video editing and day to day tasks like word processing, email etc.
    How would the performance of the Macbook Air with the Core i5 with 4 gb Ram be compared to the old Macbook Pro 15 with Core i7 Quad 2.0 ghz with 8 GB Ram.
    Thanks
    Sunny

    The main advantage would be a solid state drive. This will improve performance and speed moreso than RAM considerations. The disadvantage will be a loss of storage space. Moreover, one of the disadvantages of a SSD is that the more storage space used on it, the slower it becomes and the quicker it will deteroriate.
    If you do video editing, I would take the GPU into consideration. Does your 15'' come with a discrete GPU? The integrated GPU on the MBA (intel HD 5000) is better than the 2011 MBP integrated GPU (3000), but it includes no discrete GPU.
    Depending on how much storage space you use on your HDD currently + how many graphics intensive programs you run, you may want to consider upgrading your current machine with a SSD, upgrading your RAM on current machine to 16 gb (~160$ through macmemory or newegg), or purchasing a new Macbook Pro rather than Macbook Air.
    Last thing I would add:
    You will never be able to upgrade MBA RAM. It is soldered to the logicboard on the new models, non-retina included. You may wan to opt with the 8 GB RAM configuration.

  • Why is my Macbook Pro Running So Slow. I have the i7 2.8 GHz. I Have the Late 2011 version. I Have 4GB Of Ram. Help!

    I have a 2.8 GHz Macbook Pro with 4GB of Ram and also it's the Late 2011 version. It's also a i7. ALSO IT HAS 750GB, Why is my Mac Running SLOW!!!!!!!!

    Frankly, I was dissapointed when I got my MBP last year.  Moving from a single core, windows laptop with 2GB of Ram and an IDE HD, I expected better performance from my new 2.2Ghz i7 quad core, 4GB RAM MBP. I got the hi-res antiglare upgrade because more screen real estate is always good.  I do a bit of multimedia work so I upgraded the HD as well to the 750GB 7200 RPM option.
    I fired up my new mac, downloaded updates, loaded up my software and was off to fresh new beginnings. During the first week  I started seeing the "spinning umbrella"  Even during simple tasks. With only a few apps open the system was sluggish. Even the dock would jitter. Being a bit tech savy I opened up the activity monitor and saw that the system was running low on RAM. Who would have thought that 4GB of RAM would not be enough? My previous machine had 2GB of RAM and did the same tasks quite reasonably. Anyone would have concluded that a machine with double that would perform better. Aparrently not. At least not this MBP.  I was so upset because I just spent about 2000 USD for the "best laptop we've build to date" WITH UPGRADES! and I'm going to have to spend more to upgrade the RAM.
    Anyway I upgraded to 8GB of RAM and runs reall really smooth now.
    My suggestion if your MBP is running slow, is to upgrade your RAM to 8GB or more. Check out the guys at Other World Computing, they have lots of upgrades for macs.
    Here is a link http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade
    The hard  truth cut through all the marketing and hit me. I'll say it this way; a computer is a computer, is a computer. Forget all the hype. With the same specs, a mac gives just sbout the same performance as a PC. That said, I really love my MBP(now that I have 8GB of RAM). This mac gives me the best computing experience I have ever had. Apple really shines in their User interface and user experience. I really love the gestures and hot corners, and mission control. I usually have a lot of apps open the same time, so those features really help in switching between my apps.
    I'm going to further upgrade my RAM to 16GB and upgrade the HDD to an SSD pretty soon. I want my machine to be really snappy.
    I hope this was helpful.

  • Do I go with the MacBook pro or the MacBook air? I'm going into 8th grade and were required to have labtop. I Also edit videos for my YouTube chanel. Which should I get 13 inch model.

    Do I go with the MacBook pro or the MacBook air? I'm going into 8th grade and were required to have labtop. I Also edit videos for my YouTube chanel. Which should I get 13 inch model.

    MacBook Air: thin, light, fast SSD storage. Cons: not upgradable, expensive.
    MacBook Pro: cheaper, upgradable, better graphics card, more storage and RAM for the buck.  Cons: not as light
    you'll get more for the money with the MacBook Pro. the Air is better as a second computer for people.

  • Which should I do due to my slow MacBook Pro--upgrade or add an Air?

    I have an early 2011 MacBook Pro. 2.3 GHz core, 4 GB RAM, HHD. It is SLOW. Tried a lot of things, but the bottom line is that we have to spend some money for it to work for us... switching accounts takes a lifetime. You can forget fully booting up iPhoto in less than a few minutes.
    So... which option should we go with? (Money is a huge concern, but I'd rather spend a little too much now than not enough now and more later.)
    Option 1: Using my education discount, get a MacBook Air for me, install the one big program I use with an external CD ROM, and otherwise use it solely for documents, email, and internet. Probably get the 11" and upgrade the RAM. (Is it worth an upgraded processor and bigger SSD?). The MacBook Pro becomes the "family computer," but I only ever access my account when I need to access my photos.
    Option 2: Upgrade the MacBook Pro, get a Samsung 840 Evo SSD installed. (Pay $150 for someone to do it... I'm not messing with it.) If I go with this option... is it worth spending extra for 500 GB instead of 250? And is it worth doubling the RAM from 4 to 8?
    I'm looking for the option that will mean the least amount of money over the next 4-5 year span... I don't want to go with option 2 then find out it wasn't good enough to last us more than another couple years and then have to get another computer anyways.

    Option 3: Identify the problem that's causing the machine to run slowly.

  • Late 2013 Macbook Pro Retina 15' will not boot an external disk from a Mid-2012 MAcbook Pro. What should I do?

    In order to simplify moving all my files from the previous mid-2012 macbook pro 15' when moving to my new late-2013 macbook pro, i superdup-ed the full hard-disk to an external ssd. Unfortunatelly the new mac resuses to boot from this external disk (i get the grey disk with a line over it). The external disk works just fine so if I boot the new mac from its internal SSD I can read/write the external disk without problems.
    Old OS X is 10.9 as is the OS on the new mac.
    What I need to do is to boot the new mac from the external ssd, use the same superduper to copy the external content onto the internal ssd.
    How can I solve this issue?

    Welcome to Apple Support Communities
    If you made a backup of your files with SuperDuper, use Migration Assistant (in /Applications/Utilities) to transfer your files from the external drive > http://pondini.org/OSX/MigrateLion.html It will create a new user account with the transferred files, so you may want to merge both user accounts > https://discussions.apple.com/docs/DOC-5472
    The Late 2013 MacBook Pro uses a special OS X Mavericks version which makes OS X compatible with it, and older OS X versions do not work with it. That's the reason why you cannot start up from the external drive created from the Mid 2012 MacBook Pro

  • Elgato TV - which tuner should I pick?

    Between the Hybrid and the 250 plus, which one should I pick. I would go for Diversity, but I really want to hook up my XBOX 360 to my iMac.

    If you want to use it for gaming, you want the eyetv 250 plus. It is a hardware encoder and therefore doesn't have the latency (delay) of the eyetv hybrid.

  • Should I get a 2008 MacBook Pro 2.4ghz with 4gb of ram or macbook aluminum 2008 2.4ghz 4gb of ram? And which is thinner?

    Hello everyone I would like to know if I should get the 2008 MacBook Pro non unibody 2.4ghz 4gb of ram or should I get a macbook aluminum unibody with the same specs? And does anyone know which is thinner?

    Go with the aluminum, which is also thinner. The Late-2008 aluminum model is the oldest model MacBook capable of running the latest version of OS X (Mountain Lion).

  • Which should I use to import my photos in tho my MacBook Pro - iPhoto '11 or Lightroom 4 ? And, why, please ?

    I have two questions, please.
    1. Which should I use to import, edit and manage my photos - iPhoto 11 or Lightroom 4, and why?
    2. How do I save my edited photos as albums and export them to be stored in my Apple Time Capsule for members of my family to import and add to their Apple devices.
    Thank you.

    This is an impossible question for anyone to answer for you. Only you know what you're shooting - Raw or Jpeg? Are you a Pro or an Amateur? If you're an Amateur are you a serious hobbyist or just a guy who snaps pics at the kid's birthday parties to send to Grandma.
    You can compare the feature sets of the two apps. In a nutshell:
    iPhoto is a $15 app. It's designed with the family snapper in mind. For that you get a lot: Lossless processing, complete management, lightweight editing, integration throughout the entire OS.
    LIghtroom is about $150 these days. It's designed for a professional setting.  For that you get lossless processing - but a lot more fine control, less management, powerful editing, no integration with the OS.
    From a photography point of view, if you're a pro or a serious hobbyist then there's no discussion. If you're not, then LR might well be a sledgehammer to crack a monkey nut.
    If you want all the convenience of iPhoto with the power of Lightroom, check out Aperture.
    As to your Q2: depends on your answer to Q1. But that's not an intended use of a Time Capsule.
    Regards

  • Which memory ram is best for macbook pro i5 Mid 2012

    Hi,
    I want to upgrade my RAM but i don't know which specification or brand is good.
    1333 Mhz or 1600MHz, accurate latency?
    Pls Help me.

    Visit the Crucial website and click the System Scanner tab. Download a small app, unzip and run it. Your model # will be reported back to Crucial and you'll be offered the upgrades compatible with your machine.
    OWC is also a good site for ordering RAM, but they're a bit pricey compared to Crucial.

  • 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.
    Triple-click anywhere in the line of text below on this page to select 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.

  • Mid-2013 Macbook Air Battery Life has become awful-Not Mavericks related

    I have a Mid-2013 Macbook Air that I bought in July. i5, 1.3 GHz, 8GB RAM, 500 GB SSD.  I honestly thought that my horrible battery life was due to the recent upgrade to Mavericks (many MBAir users are having problems with 10.9), so I downgraded to 10.8.5 this AM.  With my backlit keyboard off and the screen at a mid-level of brightness, I am barely getting 2hrs of battery life.  Before I go make an appointment with the Apple Genius, I was wondering whether anyone has any suggestions.  I saw other threads on this issue, but none of them seem to really help.  Below is the EtreCheck file (there seems to be a lot of Symantec traffic, but I am not sure that is the cause).  Also, I am also running  "hidden" so I wonder if the constant location services are draining the battery.  Again, any help would be greatly appreciated.  Many thanks.

    Yes,
    After Mavericks install, your "time remaining" WILL BE INACCURATE until you do a SMC reset in many case
    SMC reset
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    There is a HUGE distinction here about someone getting less batt. life in actuality .......or are they just reading the "time remaining" and using that as a true indicator which is certainly is not.
    Ive seen 3 notebooks after SMC reset jump 4+ hours in "time remaining" and slowly climb after 3+ full charge cycles.
    Until things settle down, nobody should trust what the 'time remaining' says.

  • Which should I buy - MBP or MBA?

    I live in Bahrain and so can't really order anything from the Apple store as they don't ship it to Bahrain. I have never used a Mac and would now like to transition from PC to Mac as I am totally in love with the iPhone 4s and the new iPad.
    I am confused on which Mac I should get. I am keen on getting the MBP Retina display but not sure if I should go for the 2.3 or 2.6ghz. But then again I can't upgrade in future so was wondering if I should go in for the normal MBP 2.6ghz which works out to the same price as the MBP Retina 2.3ghz plus I can upgrade it in future if the need arises. But since I am not a professional photographer nor a video editor nor a graphic designer, I was wondering if I would need all that power? Should I just stick to a MacBook Air instead? I would be using it for everyday use like surfing the web, writing blogs, using iWorks or Office and even maybe the occasional use of Photoshop but only light use as I am not an expert in it. But whatever I choose I would like it to last me for a good 3-4 years at least!
    Presently my heart is set on the MBP Retina 2.3ghz but looking at the price tag I am not sure if it's the right move. Please help me choose the right Mac for me.
    Thanks in advance!

    Thank you all for your suggestions! I considered the 2.6Ghz regular MBP as it did cost the same price as the base model of the Retina MBP but after checking again and again on various websites, as well as apple.com, I realized that if I go for it I still end up with a max of 8GB RAM as it cannot be upgraded beyond that. What's the fun in that!?! The same hardware specs (other than the Ghz speed) are available in the base model Retina MBP but with a SSD drive (even though it's 1/3 the capacity).
    Secondly, I have been using a Sony laptop with 4GB RAM for the past couple of years and to get a laptop with 8GB RAM would be great! I don't think I would upgrade beyond that anyway! Especially not for the applications that I plan on running on it... Again, I am not a photographer nor a graphic designer nor a video editor... Plus I have a 500GB HDD but I have barely exceeded 50% of it as I download a lot of movies. But once I transfer them to my portable HDD's I have a lot of free space left! So I think the base model for the Retina MBP would suit me fine with 2.3Ghz, 8GB RAM and 256GB SSD. I would love to go in for the 2.6Ghz version but unfortunately it is out of my budget. If I could afford that then I would definitely go in for the 16GB RAM as well! But my pockets aren't that deep and will have to settle for just the base model config.
    Thanks again everyone!
