Yes, the i7 will extend battery life when doing processor intensive tasks compared to the i5, but eat up more battery when doing low exertion tasks. The more memory you have, the more battery life will be reduced as well — this is why Apple has kept the RAM relatively low in its mobile devices other than laptops. I do not believe that the size of the SSD ...

Your cofiguration of the macbook air 13" will not have any effect on your battery. Some programs have a higher inpact on your battery, like iMovie, a virtual machine,... Lets say havier programs effect your battery time in a negative way.

The 13 inch MBA gets up to 12 hours with Intel i7 processor. That is actualy more than the 11 inch MBA which gets up to 9 hours. Main reason is battery capacity, 38 vs 54 watt hours. The larger SSD and more RAM have negligible power consumption. For example: 4 Gig RAM consumes 4 watt, while 8 Gig Ram consumes 8 watt, but on the other hand the i7 CPU ...

I assume that was a typo. It is not Control-r it is the command-r to get in to recovery mode. In order to get back to Mavericks you will need the Mavericks Installer file on a USB stick.

Answer found on apple boards: by Majicman in Nov 13, 2009 1:13 AM I'm an Apple technician who works for a self-servicing provider. This happened to me today as well. Reboot didn't fix it, neither did a new user account. Here's what I did that did indeed fix it: Boot into single user mode. (hold down command + S on reboot) Wait for the ...

You could make a backup using time machine to an external harddrive. When that is completed shut down your mac and reboot it with the alt-key pressed. You will get in a menu where you can choose which drive you want to startup from. When you have os x 10.10 installed you will see the drives "Macintosh HD" amd os x 10.10 recovery. Start you mac from the ...

I had a similar issue with a client's laptop trying to install NI Kontakt Ultimate 10 (~ 330 GB) on a SSD with 400 GB "free" space. Probably TimeMachine local snapshots is enabled on your Mac. Local snapshots are basically backup files stored on your local hard-disk (as opposed to regular ones stored on the external TimeMachine volume). This is a useful ...

The message is reporting when you are with in <3% of disk capacity. You are actually at 2%! Use the Omni Disk Sweep app, which will give you accurate report on who is using how much. Example: Finder reports Used: 123130679296 bytes (123.13 GB) Omni reports: about 118 GB from this portion (my system has reserved 4.7GB as Virtual memory), that makes ...

At the lower left corner of the Network page in System preference, there's a "+" button. If you click it, you will have a drop-down window asking you how you'd like to create a new network service. From there you should be able to select "Wi-Fi" as its interface, and give that service a name. Then click "create", and you should have the "Wi-Fi" tab back. ...

Figured it out. Opened up the laptop, and a wire was lose right by the fan. That seemed to be the charging issue. Another wire was lose on the other side, may have been audio. Everything works great now! Prob bumped the air a little too harshly.

GrandPerspective is a great app to visualize the files taking up the most space on your Mac. Next time you want to delete a file, use GP to scan your computer before and after you empty the Trash, and see what's still taking up space.

Have you tried restarting the computer. It may have not refreshed the current available storage.

Okay, now that we have clarified what the issue is, here's how to solve your problem.

I remember asking the guy at the Apple store this very question back when I bought my black MacBook 13" back in 2007. From what he said and from what I've read over the years regarding battery health, most of what Apple have stated on the page you referenced is applicable to you. If I could offer some more advice, it would be this. Cycle your battery at ...

So I solved this problem by creating the Bootable USB stick by booting into my old hard drive and downloading and installing the recovery disk on the USB stick. Before I made the bootable USB stick on OS X Yosemite.

If your Mac supports Snow Leopard, and you have or can get an install disc for it, you could install SL on an external hard disk and boot from that when you need to run this DVD - restart, wait for the startup sound then hold down the Option key to choose which volume to start up from. That way you don't need to mess about with your current Lion install. If ...

You will need to use a computer with 10.6 (snow leopard) or earlier if you want to run that software on a Mac. Maybe a friend has an older computer you can borrow. Or maybe it will work on a computer lab machine. Other Options: 1) Try running it on a Windows PC (I'm guessing backwards compatibility will be better) 2) Virtual Machine. It looks like Snow ...

I have seen another fix-- a friend booted into recovery partition (cmd r at boot) and repair your disk from the disk utility there. He now has no problems whatsoever with his old mac.

The button is for checking the current battery level without having to boot the the MacBook Pro. 8 LEDs mean a full charge; 4 LEDs a 1/2 charge, and so on down.

In case anyone is reading this now, the 13" Retina screens can be put into a higher-resolution scaled mode 1680 x 1050 mode which is still readable. It's the same as the Macbook Pro 17" I used to use, just in a smaller space. This is ample width for using XCode or other IDEs

One way to accomplish this would be to test the performance in a virtual machine configured to represent a more limited processor. Assuming you're using a Mac which came with a pre-installed OS, you'll probably need to buy an additional Mac OS license, but the virtualization can be done for free with VirtualBox, or for a moderate cost with Parallels or ...

vkvau is essentially correct, when you sync your iPad to your Mac iPhoto should open and give you the option of importing all/selected pictures/videos and then an option to delete them. It's all quite easy and exactly as the iPad was designed to work.

Disconnect from the network and reboot the Mac. Then see if the process can clean itself up. Assuming it is under control, open system preferences and turn off all automatic checks under the app store pane. At that point you can reconnect to the internet and see if things are solid before opening the App Store app again.

You can also use a Windows screenshot tool, such as LightShot and Free Screenshot Capture. They are light-weight applications that allow you to capture any region of the screen and provide basic annotating options.

For starters, this machine won't run anything later than Lion anyway. I'd suggest putting in a 60GB SSD, and give it a clean installation of Lion. I have I have this model, which is almost the same. I added an SSD, and even with 2 GB of RAM, it's a fantastic and zippy browser/email client.

So many wrong answers. It's the OLDEST versions that are faster, someome said why, because the new ones require more resources. I've tested it. With the same hardware, the newer, the faster. Yosemite SLOOOOWWW compared to going back to Lion/Leopard. Just find whatever software you use and see it's OSX requirements to decided how far back you can go. The ...

I found problem. The problem seems to first exhibit itself during graphics-intensive tasks like playing games or high-definition video, or running the CPU hot. The display ends up distorting, or going entirely blank, and while reboots make the problems go away for a short period of time, they almost always return later. After the graphical glitches start, ...

2560 x 1600 is more than "fullHD" or whatever marketing terms they use these days (or those days). 1080p - is often called "fullHD" and is 1920 x 1080 resolution. QuadHD is quad (4x) 720p or 2560 x 1440 resolution. The old high def resolution is 2560 x 1600 - this is the resolution of old professional or similar monitors -such as Apple's old 30" cinema ...

There is no safety difference whatsoever. The 3 pin grounded cable goes to a 2 pin connector which then plugs into the adapter. This means that the grounding is not even connected so there is absolutely no difference safety-wise. Main reason is for those places where you have to rotate the wall plug to insert, or you need to insert a grounding pin in to ...

Months late on this one - but there is no point in grounding a double-insulated device, such as a power-supply. There is no earth circuitry inside it anyway. If you ever see a similar device with an actual cable leading into it, you'll notice it runs on only 2-core wire. UK adapters always have the 3rd pin, but that is simply because the pin is needed to ...

When I asked this question, I only had one option in the audio output devices list in my audio preferences. When I went back some time later, I noticed an option called [someone's name] - Macbook Air. I accidentally clicked it, and quickly set the setting back to my headphones. This seems to have fixed the problem.

Disconnect everything from the Mac and then power it off. Perform recovery according to these steps. http://support.apple.com/en-us/HT4718 If that fails, then you may need support from Apple to determine the version of OS X that shipped with the Mac so you can restore that and start over/restore from a backup once the hardware is known to work. Or it ...

Let me summarize the troubleshooting steps. Before disassembling: 1- Run the Apple Hardware test to see if it comes up with anything. 2- As far I know you have a NVIDIA graphics car.
