How to Check for and Install Updates on a Mac Computer. In this Article: Updating App Store Apps and System Software Enabling Automatic Updates Updating Apps Installed Without the App Store Upgrading to a Newer OS X Version Installing Updates in Legacy OS X Versions Community Q&A.

I am working on Ubuntu. How can I get MAC address of my machine or an interface say eth0 using C program.

  • Getting rid of programs on a Mac can be easy. Or difficult. Easy because in most cases you simply drag the program's icon to the trash and the software disappears.
  • When you install a program, check to see how to uninstall it. Make a note if it has its own uninstall utility or instructions. Before you begin any uninstalling process, check to make sure your trash is empty or contains nothing you might want to save.

You need to iterate over all the available interfaces on your machine, and use ioctl with SIOCGIFHWADDR flag to get the mac address. The mac address will be obtained as a 6-octet binary array. You also want to skip the loopback interface.

Much nicer than all this socket or shell madness is simply using sysfs for this:

the file /sys/class/net/eth0/address carries your mac adress as simple string you can read with fopen()/fscanf()/fclose(). Nothing easier than that.

And if you want to support other network interfaces than eth0 (and you probably want), then simply use opendir()/readdir()/closedir() on /sys/class/net/.

You want to take a look at the getifaddrs(3) manual page. There is an example in C in the manpage itself that you can use. You want to get the address with the type AF_LINK.

Using getifaddrs you can get MAC address from the family AF_PACKET.

In order to display the MAC address to each interface, you can proceed like this:

I have just write one and test it on gentoo in virtualbox.

Assuming that c++ code (c++11) is ok as well and the interface is known.

  1. On Linux, use the service of 'Network Manager' over the DBus.

  2. There is also good'ol shell program which can be invoke and the result grabbed (use an exec function under C):

$ /sbin/ifconfig | grep HWaddr

A very portable way is to parse the output of this command.

Provided ifconfig can be run as the current user (usually can) and awk is installed (it often is). This will give you the mac address of the machine.

This is a Bash line that prints all available mac addresses, except the loopback:

Can be executed from a C program.

Files you download from the Internet are often compressed or zipped so that they take up less space and arrive much faster than files that haven’t been compressed. You can easily identify compressed files by their extensions, such as .zip (a common standard used in OS X and Windows) and .sit. Before you can use these files, you must learn how to unzip files on mac computers for proper access – luckily the process isn’t that complicated!

How to unzip files on mac computers

Unzipping a file on a mac computer is user-friendly and intuitive. To unzip files on a mac, simply follow the steps below:

  1. Double click the zipped file.
  2. The file will automatically be decompressed by Archive Utility into the same folder the compressed file is in.
  3. Access the extracted files by clicking the appropriate icons.

Alternatively, if the method above does not work, you can right-click on the .zip package, and select Open With > Archive Utility (default).

Apple and third party software

Apple used to include a program called StuffIt Expander to decompress zipped files, but doesn’t now that OS X lets you unzip files (but not .sit files). However, StuffIt from SmithMicro Software still comes in handy for opening other types of compressed files, notably the .sit or .sitx compressed types. Go to www.stuffit-expander.com or www.stuffit.com/mac/index.html to download a free version of the software or to splurge for the Deluxe version. In addition to compressing files, StuffIt Deluxe lets you encrypt and back up files.

Meanwhile, you can archive or create your own .zip files through OS X, which is useful if you’re e-mailing a number of meaty files to a friend. Right-click (or Ctrl-click) files you want to compress inside Finder and choose Compress Filename. The newly compressed files carry the .zip extension. The archive is created in the same location as the original file and is named originalfilename.zip. You can also choose File→Compress. If you compress a lot of files at once, the archive takes the name Archive.zip.

By default, compressed files are opened with the Archive Utility. It appears in the Dock (in Leopard) while the files are being unsqueezed, unless you choose to open them with Stuffit Expander or some other program.

On the flip side, you can also archive or create your own .zip files through OS X, which is useful if you’re e-mailing a number of meaty files to a client or friend. Follow the step-by-step instructions below to easily zip files on a mac:

  1. Right-click or Ctrl-click the multiple files you want to compress (whether on the desktop or inside the Finder).
  2. Select Compress Filename from the pop-up menu.
  3. The files are now compressed in a .zip extension and the archive is created in the same location as the original file name, except with the .zip appended to its name.

On some Apple computers, you can also compress a file by simply choosing File→Compress. If you compress a lot of files at once, the archive takes the name Archive.zip.
