How to use AirDrop over Ethernet and on older Macs running Lion

12:33:00 PM

AirDrop is a new feature in Mac OS X Lion that makes sharing files between Macs easier than ever. There are no accounts to sign into, networks to connect to, or preferences to set up. Some Macs don’t support AirDrop, though, and sharing over Ethernet isn’t possible by default.

Transferring files from Mac to Mac is so easy in Mac OS X Lion that there’s barely anything to it. Just go to the AirDrop menu in the Finder sidebar on both Macs and they will automatically find each other. Next, drag one or more files to the icon of the computer you’re sending them to. The person on the other end will approve the transfer and that’s it!

While the beauty of AirDrop is its simplicity, that doesn’t mean there aren’t caveats. For example, the awesome technology that lets AirDrop work without both Macs being connected to the same wireless network (or any network at all, for that matter) also makes the feature exclusive to recent Macs. Apple has a rundown of Mac models which support AirDrop on their website and the list is limited to those that have a special kind of wireless chip inside them. AirDrop relies on Wi-Fi’s PAN (Personal Area Network) interface, which is capable of establishing peer-to-peer connections. But what if your Mac doesn’t support PAN, even though you’re running Lion? A couple lines of code will keep you from feeling left out.

Launch Terminal (located in Applications > Utilities) and paste the following command:

defaults write com.apple.NetworkBrowser BrowseAllInterfaces 1

Press Enter to run the command.

Next, paste this line in Terminal to restart Finder:

killall Finder

Press Enter again and you’re ready to go!

Let’s say you have two Macs running Lion – one that supports AirDrop out of the box and another that is unsupported. If you’re going to be using this technique to share files between them, it’s a good idea to follow steps 1-4 on both computers. You can always reverse this setting by going through the process again, except replacing the 1 at the end of the first command with a 0.

What exactly have we just done? In essence, we’ve told AirDrop to work over any kind of network, not just a PAN. The only difference is that now both computers need to be connected to the same local network in order see each other and transfer files. So you can have one Mac connected to your network over Ethernet and another connected via Wi-Fi. Perhaps both have Ethernet, or maybe both have Wi-Fi. Whatever the combination, it’ll work just the same.

One thing to keep in mind is that Apple likely chose to only allow AirDrop to work over PAN connections because they are heavily encrypted. Whatever files you transfer using AirDrop with its default settings are secured and safe from snoopers. With the technique in this tutorial, you’re getting more flexibility at the cost of security. Files are only as safe as the network you’re connected to. If it’s your home network, it’s probably no big deal. If you’re using the public Wi-Fi atmake sure you’re not sharing anything important.

How To Partition your hard drive

9:59:00 PM

Sometimes we need to separate our hard drive into independent chunks of space and we call thispartitioning. This is most often not needed, but if you want to install another operating system on your computer you will find this to be needed or to protect a system from failure. (Please note that this does not protect you from hardware failures)

Partitioning on the Mac is quite simple, you first need to launch Disk Utility application, found in /Applications/Utilities. After launching the Disk Utility, just click your Hard Drive from the list to the left, in this case 320 GB WDC WD32…, and then select the tab partition, as pictured below.

From here all we need to do is select the partition we want to resize, we will use Macintosh HD. Then click the plus sign in the lower left hand corner. A new partition will show up in the list, here it is Macintosh HD 2*. We will want to select it, as we did previously, and modify the Name, Format, and Size, a break down follows:

§ Name – The viewable name of the partition (as we see the drive in Finder)

§ Format – The type of partition, used by various operating systems (i.e. Windows 7, OSX, or Ubuntu) and for various purposes.
Note that a partition format can usually change when installing an operating system.

§ Mac OS Extended (Journaled) – Most often used with Mac OSX Systems. [learn more]

§ Mac OS Extended (Case-sensitive, Journaled) – Most often used with Mac OSX Server Systems. [learn more]
Not recommended for most users due to incompatibility with some applications including Adobe Photoshop and the Adobe Suite.

§ MS-DOS (FAT) – Most often used with Windows operating systems prior to Windows XP (NTFS). [learn more]

§ ExFAT – Most often used with Windows Server operating systems. [learn more]

§ Free Space – An unformatted partition.

§ Size – The amount of space you need, in Gigabytes. As a very rough standard most operating systems need at least 20 GB.

Finally you’ve reached the last step, hit Apply…. Wait for it…. Voila, you have a new partition!
