Macbook air 4gb vs 8gb?

Hi, i wanted to post this question because I want to buy a macbook air , 11 inch, i5, but i don't know if is better to buy it with 4gb ram or with 8gb.
The thing is, that there is a offer in a shop of my city and they give me like $100 in coupons buying the macbook with 4gb.
The price of the macbook in the shop is the same price as the macbook here with education discount and also have the cupons.
But i'm student so I can buy here the macbook with education discount, and if I add the 8gb ram, the price raises only about $100 but i don't get any cupons xD
So what do you think is better?
I'm university student, so I use the computer for writing, for excel and powerpoint, internet and email and maybe I will need to use some statistics software like spss...

Having a lot of RAM isn't necessary for a normal high school or college student that's just going to be using their computer for word documents, powerpoints, or just surfing the web. I actually have a Mac Air with 2GB of RAM and it's from late 2010. I use my compter for the same things you are planning to use yours for and I have never had a problem with it in the three years I've had it.
The minimum amount of RAM you can get on the Air today is 4GB just incase you were wondering and I think that's plenty for you. If you decided to start using your Mac for photo or video editing then you might want to upgrade to the 8GB RAM. You can actually go to an Apple Store and have them install more RAM for very little money. I think it's under $100 but I couldn't be sure.
There's no such thing as having too much RAM because basically the more RAM you have the better your computer is but 4GB is plenty considering 2GB is plenty for me and it sounds like your planning to do the same thing as me when you get your computer.

Macbook Air 11" (2012) 8GB Ram, 128 GB SSD: i5 vs. i7 as travel companion for a little LR4/Aperture 3

Hello everyone,
I am about to buy a MBA 11" for my early 2013 four week trip to Asia. I travel about 2 1/2 months a year and was wondering if the 180€ upgrade to i7 was really worth it?
Besides the obvious movies and web browsing I plan to be taking around 50 pictures a day with my Canon S100 and do some Lightroom 4 or Aperture 3 retouching on a dozen or so of them.
Any suggestions?
Best Regards,
Vincent

Vincent,
I've been using Lightroom & Aperture on and off as a "casual enthusiast" for the past 4 years across multiple different machines (i3s with 2GBs of RAM, i5s with 4/8GB, i7s with 16GB) and I've come to the conclusion that it boils down to this -
1.) You can never have enough available resources/processing power. Whether it's RAM or CPU, you won't find yourself ever saying: "Man this computer is too fast for my needs." When you tell your computer to do something, you'll always be waiting for it to then perform that action. It might 1 milisecond or 10 minutes but you're still waiting even if it's so fast that it gives the appearance of an instant response.
2.) "Maxing out" a unit is an excellent strategy when purchasing a computer. Especially on computers, like the MacBook Air where upgrading them at a future point in time to keep it current is impossible. The CPU you buy today will be the CPU you'll have until you part with the computer. So bumping things up to the maximum like RAM and CPU capabilities would be considered as smart by people who like to "future proof." That being said, if you're the type of person (like myself) who upgrades their portabilities every 8-14 months this maxing out strategy may not be most beneficial. Especially considering, in my case, I sell my existing unit in preparation for the newer models and in order to reduce my out of pocket find that the base models resell much faster and with the best ROP (Return on Purchase, I don't consider a computer an investment).
3.) If you are the type of purchase, like my girlfriend, who buys a computer and will use it until the end of days (5 years typically) then maxing out every available slider, option or upgrade is almost a no brainer. Because in 5 years when the computer's hardware is barely relevant that extra oomph she purchased initially allows her to get a much better DOP (Duration of purchase) versus someone who didn't spend the extra money for the extra performance.
So personally, if you can afford the CPU upgrade, you intend to hold onto the machine for several years and you value your time as money then every bit helps. I'd say... Go For It!
However if the finances are tight, if you don't intend to make this 11" MBA your bread & butter, go to, workhorse then hold off and put that $$ to use on something like AppleCare, peripherals or accessories.
Yes, the i7 is faster. But at the end of the day it's still a dual core low voltage CPU and the differences between both CPUs in practical usage is not going to be so extreme that time will stop.

Adding ram to mid-2009 Macbook Pro - 4gb vs 8gb?

I want to add ram to my mid-2009 Macbook Pro. It currently has 2gb ram. Any thoughts of whether I should upgrade 4gb or 8gb ram? It has a 2.26ghz intel core 2 processor. I only use the computer for internet and the occasional document editing.

If your needs are that modest, then 4 GB is fine. However, Mavericks is designed to use as much RAM as is available, and so more RAM is always better.
If I were you, I would put 4GB of RAM in, and then buy an SSD to replace the hard drive. You will be surprised how much faster it will be! It's the best way to extend the useful life of a older Mac.

Can i upgrade the RAM on a new macbook air? (thinking 8GB)

that's the question.

no, you cannot.
the RAM is not upgradeable because it is seal on the motherboard originally from apple factory.

Logic on a MacBook Air?

I'm considering purchasing a MacBook Air, 13 inch i5 with 8gb RAM.
I'm just wondering if logic pro will be useable on this machine?
Does anyone have any experience with this?
My demands arent all that professional.

I run Logic on a 2011 i5 1.7ghz 13" MacBook Air 4gb/256gb and it works great. It should be even better on a 2012 model with more RAM (although I don't have any problems with 4gb). The SSD is great, I get latency between 6.1 and 6.9 ms with a 64 sample buffer, depending on what interface I use. I use my old 23" Apple Cinema display as an external monitor.
I would get the biggest SSD possible though. If the 512gb had been available in 2011, I would have gotten it. Although USB 3.0 on the 2012 model should also help if you want to use inexpensive external drives.

Mid 2013 macbook air keyboard/trackpad stop responding

I have a mid-2013 13" Macbook Air - 512GB SSD, 8GB RAM - 1.7Ghz i7
I spend a good deal of time working at my home, where I have two external monitors (one via USB, one via the thunderbolt port) and a bluetooth wireless mouse and keyboard. Things are great.
I also go on the road, and when I do, I simply unplug my monitors, close the lid, and go.
Lately, I've had some very odd behavior happen which acts a lot like what is described in the latest 13" Macbook Pro Retina EFI fix: http://www.macrumors.com/2013/11/07/apple-releases-fix-for-13-inch-retina-macboo k-pro-keyboardtrackpad-issues/
Here's what happens....when I'm traveling and away from my bluetooth keyboard/mouse, I will open up my MBA and the trackpad and internal keyboard are unresponsive. I can press the power button and get it to turn off...power it back on and am able to use the keyboard to control various boot options (diagnostics, single-user, safe-mode, recovery model, etc). Booting up full, however, the issue will still exist. Looking at the console log, when this is happening, there are a ton (about 4000 every minute) of the following :
11/1/13 7:45:26.000 PM kernel[0]: Error: AppleHSSPIController::doSPITransfer CRC from device was invalid
11/1/13 7:45:26.000 PM kernel[0]: Error: AppleHSSPIController::InterruptOccurred Failed to transfer interrupt data with Err (0xe00002eb)
Eventually, something happens and things start to work -- I will generally see the following in the console log when it starts working:
11/1/13 7:45:27.000 PM kernel[0]: Apple Internal Keyboard / Trackpad::start Start Succeeded
If I let the machine sit at the unlock screen, eventually a dialog comes up and says "unable to find external bluetooth keyboard/mouse..." It says it will continue to search and will pair with one eventually....it's the same message I would get from my mac mini if it couldn't find the bluetooth keyboard (and has no internal/hardwired keyboard).
When it is happening, I can use "cmd-r" to boot into recovery mode and recovery mode will complain about not having a mouse/trackpad - yet the keyboard seems to work to control what happens at boot time.
I called Apple and got sent to the apple store with a "it sounds like a faulty logic board or a connection that needs soldering". The Apple Store "genius" didn't quite think that was the case and has instead suggested I re-install the operating system. I'm non-plussed by both suggestions. This has happened both before and after Mavericks...
On one of my latest trips, I had a case where I took my laptop out on the plane to try to use it...only to have this issue occur. I landed, got to the hotel, tried again and everything worked fine. Went to dinner - leaving my laptop on the desk plugged in - only to come back to have the keyboard unresponsive.... I've now resorted to traveling with my bluetooth keyboard and mouse "just in case".
Any ideas/thoughts?

I will open up my MBA and the trackpad and internal keyboard are unresponsive.
Do four things to test for fault on this,
reset SMC ,
reset NVRAM,
uncheck "put hard disks to sleep"
and UNPAIR both your bluetooth mouse and keyboard from this Mac that you are using with it currently.
yes, the notion that your logic board is at fault is extremely unlikely, additionally (though far more likely) that your Mavericks OS is corrupt.
RESET SMC
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.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
RESET NVRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Lastly, go into SYS PREFERENCES > ENERGY > uncheck "Put hard disks to sleep when possible" in both tabs.
Let your Mac go into sleep or close the lid for a few mins. and reopen and verify that your trackpad and mouse are fine. They should be after this,.........
If not contact Apple for full in shop diagnostic, theyll run a hardware test (unlikely causation) and reinstall the OS, then retest and LASTLY replace the logic board (very unlikely).

How do I install Windows 7 on my new MacBook Air?

Hey everyone, I just purchased a MacBook Air (4GB ram & 256 SSD) with Lion OS... I have been a PC user for forever & a day... I am going to be installing Windows 7 on it because Wellview is not a mac friendly program aswell as other programs. I am trying to learn the difference between Parallels, Boot Camp, etc... I understand a partition & how it works on a PC & have been reading forums in Mac rumours to try & figure it out on this system... But, what would be the easiest way to install W7? I will have to download Windows 7 OS & it sounds like Parallel but it looks like this MBA has Boot Camp already installed on it. Also, would it be better to have the thunderbolt connected to a hard drive & keep everything off of the the MBA HD? Is there a way to upgrade the RAM in the MBA? I know, that's a lot of questions... But, I would rather ask them here & figure it out rather than asking someone on the phone... Yes, I am male... LOL... One other question I have is how will the touch pad work in windows, how do you hit the typically right mouse button when this laptop doesn't even have one? I know you use the different fingers for different actions as I have been experimenting with... Just wondering on that one... I'm sure it works somehow... LOL...

OMG Morgan, you are an inquisitor .
But I will try and answer all your questions:
1+2: it depends on your demands: if you use both OS's often, and have a "normal" HDD you want to avoid restarting all the time and use a Virtualizer. With a MBA restarting is superquick. If you use Mac apps at the same time with Windows you better use the Virtualizer. But if you are having "bootcam windows" and decide to install a virtualizer later, this Virtualizer can make the VM of the bootcamp partition...
3: you can not install Windows without a disk.
4. The X stands for 10: Snow Leopard is 10.6... Leopard is 10.5... Lion is 10.7... They are all OSX. Befrore that there was OS9.
5. The Bootcamp install is very good guided: Bootcamp makes the partition on your SSD and after that it will ask for the W7 install disk (in case of a CD you need the Apple superdrive). This partition will be about 60GB for W7.
6. If you use Parallels, there is Kaspersky antivirus included (half a year), it will only install when you say yes on the install question (say no for W7) but as I said before: only use an antivirus in W7 and NOT in OSX, if you do not pay very good attention Parallels will install it also in OSX. Better use Avast, AVG, they are free, simple, fast, and good. NEVER use norton. But you can use the one you know form your PC life....
7. delete button: same as backspace, if you hold the "Fn" key at the same time it deletes forward.
8. When a new OS comes available (this not the same as update), make sure before you install it, that all your apps have compatibilty: you can read a lot of posts here of people who did not check before upgrading to Lion!
(same goes for Windows 8, when it comes).
No I don't know where W7 is the cheapest.
9. 32-bit or 64 bit: both are good, it does not make much difference either will run a 32 bit app. I use XP which is 32 bit on a 64-bit Mac OSX, and 64-bit W7. Thus: it depends what you want to run. My old Bankapps are all 32-bit and will not run on W7.
I hope I informed you enough to make your decisions now.
have fun.

Can I exchange my macbook air for the new pro?

I recently bought a haswell series 13" macbook air exactly 1 week before the introduction of the new haswell macbook pros. After considering the spec and price difference I realized I'd rather have the pro. I looked on the returns tab on the website. It said I can return my product within 14 days. Is it possible for me to exchange my air for the pro without having to go through returning my macbook air and buying the pro? I realized the price difference wasn't all that differernt and I wouldn't mind the extra power. I currently have the 13" macbook air i5 with 8gb. I plan on getting the 8gb for the 13" retina display macbook pro as well

I strongly doubt it. The best thing for you to do is to return this one before the 14 days expire. If the time passes you will have to keep the Air and try to sell it privately.
Once Apple accepts the Air back and you know you are getting a refund you can start the order process for the Pro.
regards

Macbook Air Mid-2012 UI freeze

Hi there,
I have a Mid-2012 13" Macbook Air (i7 and 8GB of RAM) with Mountain Lion and all software updates (as of 15th of November) and for the last few weeks I have been experiencing some random and very strange UI freezes.
It seems to happen while browsing with Safari and the symptoms are as follows:\
- All OS UI is frozen, including option-command-esc and all dock icons, menus, windows, etc
- Cursor still moves with the trackpad as normal
- Caps lock works fine, LED lights up if you press it
The only way to recover is to shut down (long press on power button) and restart.
I have looked at the console and there are no reports of kernel panics or any other log messages that may give a clue as to what happened.
It also occurs fairly randomly (once every few days) which makes it very difficult to pinpoint the cause.
I have browsed similar threads but so far no clues, any ideas?
Thanks in advance for any input.

The next time you have the problem, note the exact times when it starts and ends: hour, minute, second.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console 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 Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Scroll back in the log to the time you noted above. Post any messages timestamped during that interval – the text, please, not a screenshot.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into a message.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.

MacBook Air 2012 - poor WiFi connectivity

Just submitted this to Apple feedback, I know they won't respond and I know others have opened discussions on this topic already but I want to splurb...
MacBook Air 2.0Ghz, 8GB 1600Mhz, 256GB
AirPort Extreme (4th gen) 5Ghz 802.11N
Network connectivity is hit and miss. I can start up and the MacBook connects to the Extreme ok. I can start up and connection fails (referring to time outs). I can be connected for hours and then the local wireless connection to the router drops and is unable to connect again. Rebooting may or may not correct this.
Will a driver revision be written and pushed out? Or is this hardware faulty? Would be grateful if you could let me know.

Yeah I was thinking of doing that if an update is not released shortly that fixes it. I had similar teething issues with the wireless on a black MacBook I owned a few years ago which was fixed with an OS X update. if not and it drags on, I'll see if they can offer a swap.

Macbook pro vs macbook air- latest models

I am looking to upgrade my mid-2012 Pro to one of the following latest models: MacBook Pro, 4GB 500GB HD or MacBook Air 4GB, 256 Flash Storage.
I am in graduate school so I will using it for papers, research, etc but not for over two classes and not every month of the year. I usually am on everyday browsing the web, checking emails. The main purpose of it would be to watch tv shows via iTunes, Netflix, Hulu. I have purchased many shows from iTunes and have them downloaded in my library so storage is something of importance. I know that the Pro comes with a dvd/cd drive but I rarely use that. I'm not sure I would miss it but I worry. Any advice would be appreciated! Which would be the best for me? Also since I do watch a lot of television on it, how would the retina display benefit me?

Get MBP. it is a real computer. You will be able to do some work on it.

I cannot boot my 2012 Macbook Air 13" from external USB 2.0/3.0 drive.

I just purchased a new 2012 MacBook Air 13" with 8GB ram and 256Gb SSD. I have clones of my 2011 MBA drive made with Superduper on both a USB 2.0 and USB 3.0 external drives. The USB 2.0 drive enclosure contains the OWC Aura 256GB 6G SSD that used to be the internal drive for my 2011 MBA.
I cannot boot my new 2012 MBA from either external drive. When I try to do so, the MBA displays shows a gray circle with a line through it.
I can boot my MacBook Pro 2010 and 2007 Mac Pro just fine with either USB external drive. So, it must be something up with compatibility with the new 2012 MBA. All of my Macs are running 10.7.4 with all of the latest upgrades available as of 6/24/12.
Any suggestions?
Thanks in advance.

I have a drive I had been using in a 2007 MacBook that I would like to "upgrade" to a compatible version of 10.7.4 (build 11E2705), but I am having trouble finding a way to get the version of the OS on the drive without affecting the data on the drive.
I had hoped that booting from the Recovery partion on the SSD would allow me to "Reinstall 10.7" to get a compatible version, but the drive still can not boot the 2012 MacBook Air.
I may try cloning next, moving directories I want to keep to the root level of the target drive, but I wish there was an easier way to "refresh" the install of the OS to a newer version for new hardware.
I also need to find a way to "refresh" the USB drive I have for installing 10.7, to make sure it has the ability to boot new hardware, since the original 10.7.4 USB install clone does not boot the newest laptops.

Macbook air 4gb vs 8gb?
