How do I adjust the resolution of my Retina display?

If you need to adjust the display resolution choose System Preferences from the Apple () menu. Choose Display. The Retina display offers scaled resolutions that allow you to have text and objects appear larger on screen, or to make them appear smaller which provides more space on screen. Note: Scaled resolutions do not offer the same visual quality as the Retina setting. Scaled resolutions may also impact graphics performance depending on which applications you are using. Your MacBook Pro with Retina display has 2880 x 1800 pixels and starts up in its native Retina mode, which is the recommended resolution for use on this computer.

Calibrate the battery of Apple Macbookpro/MacBook Air

For any MacBook Pro/MacBook Air user, especially those who travel, a long battery life and top notch battery health are vital. The tips below will help ensure you get the most out of your MacBook Pro/MacBook Air’s battery over its lifetime.

1) Calibrate the battery once ever 1-3 months
Finally, if your battery is showing signs of shorter run times, you may want to calibrate the battery (once every 1-3 months). To calibrate the battery, follow these instructions:

a) Fully charge your MacBook Pro/MacBook Air.
b) Once fully charged, leave it plugged in for at least another 2 hours.
c) Remove the MagSafe power adapter, and use your computer until you get the battery level warning message.
d) Ignore that message and keep running your notebook.
e) Eventually the machine will go to sleep.
f) Do NOT plug it in. Instead, let it sleep for at least 5 hours.
g) After the time has passed, plug it back in, and let it fully charge.
h) Once fully charged, your battery has been properly calibrated.

2) Turn off AirPort Wireless
If you do not require the Internet and if there are no WiFi networks within range, turning off AirPort will considerably save your computer’s battery life. It is also wiser to use an Ethernet cable over wireless if the option exists.

3) Turn off Bluetooth
Once again, if there is no need for a Bluetooth device, the best thing to do is to turn off the Bluetooth feature of your MacBook Pro/MacBook Air.
 
4) Minimize use of iSight Camera
The iSight camera uses plenty of battery power. Keeps its use down to a minimum if trying to extend battery life.
 
5) Remember to eject discs from the DVD drive 
The motor in the optical drive required to spin DVDs and CDs can use a lot of power. Thus, eject your discs to maximize battery life. If you insist on watching DVDs, say on a long journey, rip them to your hard drive first instead.
 
6) Reduce screen brightness
Turn down the brightness of the screen to as low as you can comfortably work, and your battery life will significantly rise. The brighter the screen, the shorter your battery life.
 
7) Turn down/off the backlit keyboard
Similar to the brightness of the screen, keeping your backlit keyboard (if you have one) at its lowest or off will save plenty of battery juice.
 
8) Turn down volume or use headphones
Loud volume on your MacBook Pro/MacBook Air requires more energy. It is more energy efficient to plug in headphones instead if you fancy listening to loud audio/music.

9) Run fewer applications at once/turn off unneeded applications
By running less applications simultaneously, or installing more RAM, you reduce your risks of having unused parts of your memory being called for tasks, thus saving battery life.
 
10) Do NOT disable a CPU core
For all MacBook Pro/MacBook Airs with more than one CPU core, disabling a core is NOT wise. Your MacBook Pro/MacBook Airs chips were designed to run most efficiently with multiple cores active. Disabling one not only requires more power, but also generates more heat. Some users have reported losing up to 40 minutes of battery life by turning off a core!

Inside OS X 10.8 Mountain Lion: Screen Sharing adds drag and drop file transfers

Remote Screen Sharing is enhanced in this summer's release of OS X Mountain Lion, adding support for drag and drop file transfers between the viewer and the remote desktop and enhancing support for virtual displays.

Screen Sharing, a remote access feature Apple first added to OS X 10.5 Leopard to enable viewing or controlling another Mac's desktop, is gaining a feature from Apple Remote Desktop: the ability to drag files from the local desktop into a remote session.

After connecting to a remote host, the local user can now drag files to the desktop, or target a specific app, invoking Exposé to, for example, drag an image file to a Pages document, select the window of the desired document, and place the graphic in the document.

Enable AirDrop Over Ethernet & AirDrop On Unsupported Macs Running OS X 10.7

AirDrop is the extremely easy local peer-to-peer file transfer tool that is built into Mac OS X 10.7, it allows you to easily send and receive files wirelessly over a network just by dragging and dropping. It’s a great addition in Lion, but it’s not supported on all Macs.

You can enable AirDrop support on unsupported Macs running OS X 10.7+ by using the following defaults write command in the Terminal:

defaults write com.apple.NetworkBrowser BrowseAllInterfaces 1


Paste that in and hit enter. You’ll need to then kill the Finder with ‘killall Finder’ or reboot the Mac for changes to take effect.

What’s really interesting is that this enables AirDrop over both Wi-Fi and wired Ethernet connections, which basically means any machine running Lion can use it whether or not it has a wireless card. As long as it’s connected to the same network you will be able to see the Mac in the AirDrop list of another Mac running 10.7.

If you ever want to disable this for some reason, you can just use this code.

defaults write com.apple.NetworkBrowser BrowseAllInterfaces 0

Enjoy........
