MAC Operating System Interview Questions And Answers

Mac OS is a series of graphical user interface-based operating systems developed by Apple Inc. for their Macintosh line of computer systems.
Macintosh operating systems have been released in two major series. Up to major revision 9, from 1984 to 2000, it is historically known as Classic Mac OS. Major revision 10, from 2001 to present, is branded OS X (originally referred to as Mac OS X).

A Digital Subscriber Line is a popular medium for delivering high-speed Internet connections. Physically, it looks like a phone line. A DSL modem, normally provided by your Internet service provider (ISP), bridges this line to an RJ-45 Ethernet port like the one on your computer. You then connect your computer to the DSL modem using an Ethernet cable.

You have to go to options and then go to graphic options and click on the windowed mode. If it is lighted up it means it will be minimized. If it is minimized it means you can do anything you can usually do on your computer, but if for example you open safari it will pause the game. If it is not lit up it will be full screen and you wont be able to do anything else but aoe3. The graphics are better in full screen though.

No.Microsoft ActiveX controls not run on Mac OS X.

it's not mac compatible.so u can't work on mac.

PPPoE is the abbreviation for Point-to-Point Protocol over Ethernet. PPPoE is the protocol that your ISP uses to transmit information to and from a computer. Some DSL-based ISPs may not call PPPoE by name, but this information is relevant if you use a DSL modem and are required provide a user name and password in order to connect to the Internet.

Mac OS X is a Unix-like operating system developed by Apple for their Mac hardware line.
Windows is a series of operating systems, running their own proprietary kernel, that is developed by Microsoft and licensed to various computer manufacturers.

Startup Disk preference pane is simply filtering out (that is, not displaying) any mounted volumes that it doesn't consider bootable. Its definition of a Boot Camp volume includes that the mounted volume either be of type msdos or ntfs--this is hard-coded into the preference pane plugin. This doesn't mean your Boot Camp volume has become unbootable. It's merely not showing up in the GUI. You can hold the opt key during startup and choose the Windows partition to boot from. You can also remount it (read-only) using the NTFS file system built into Mac OS X and it should start showing up in Startup Disk.

You do not need connection software when using Mac OS X, so this does not affect you. Most ISPs only require the correct user name and password when your computer connects to their service. Mac OS X can do this without any additional software. Follow the instructions in technical document 106282: "Mac OS X 10.0: Setup Assistant Does Not Accommodate DSL User Name and Password.

Mac OS X 10.3 works with these Macintosh computers:
★ Power Mac G5--all models except Power Mac G5 (Early 2005), Power Mac G5 (Late 2005) which use Mac OS X 10.4
★ Power Mac G4 or Macintosh Server G4--all models
★ Power Macintosh G3 or Macintosh Server G3 that have built-in USB ports
★ iMac--all models released in 2004 or earlier
★ iBook--all models except iBook G4 (Mid 2005) which uses Mac OS X 10.4
★ PowerBook G4--all models except PowerBook G4 (Double-Layer SD) which uses Mac OS X 10.4

Try pressing Option-Command-Escape. (press them in that order, but don't release any of them until you've pressed the last one.) This will give you the option to force quit any crashed applications. However, force quitting an application will cause any unsaved changes to be lost. Your best bet is to wait a minute or so, and see whether you can quit any applications normally. If you can't, save what you can, and restart your computer.
Important note:
Before you press the Option-Command-Escape or use the equivalent command that you find in the Apple menu. (in the upper left of the menu bar) If all is unresponsive and you're seeing a "spinning beach ball", try to be sure you're in the "Finder" by making a click anywhere in a free space on the desktop or pressing the Apple key (= command) and the Tab until you'll see the Finder's icon (and all the rest of the open applications). Select it either by using the arrow keys or keeping pressed the Apple and pressing again Tab (or moving the cursor on it and releasing it).

There are also other ways if the force quit command fails.
You can open an application called Activity Monitor by searching for it in spotlight. It will show you a list of all open applications, and give you information about the amount of processor power, memory, and virtual memory being used. If a program appears to be using too much CPU or memory, or is highlighted in red, you can quit it from within Activity Monitor by selecting the program, and clicking the quit button in the toolbar. This will give you the option of a standard quit, or a force quit. Try the standard quit first, but if that doesn't work, use the force quit option.
The following method utilises Mac OS X's command line utility.
Keep the application named Terminal in the dock (you can add it dragging its icon on it).

Open it and type "top" (of course without the quotes),you'll see a list of all the open applications,if you know which one is causing the problem look at its "name" ,its ID is a number on the left,open one more terminal's window and type "kill" (it's not a joke it's a command that is called in that way) followed by that number and press the enter key (the last one on the lower right of the numbers under the plus sign) or the return key (the second biggest one after the space bar).
Some time when the first method fails this one works.
If all this is not enough just wait,if you're lucky the spinning ball will become again a cursor after some time and you'll be able at least to save all before to restart.

If the problems return try adding all the RAM you can,Mac OS X 10.6.1 Snow Leopard is very stable thus perhaps you're keeping too much applications open at the same time.
Remember that on a Mac to quit an application you've to be sure that it's in the fore ground and press command (Apple key) and Q.
In other words to close the last window of an application doesn't quit the application itself.

Windows XP can not connect to Mac OSx because they are separate platforms that do not support the same language. INSTEAD, your Apple computer has Boot Camp to separate the 2 platform systems, which the computer must be "booted" each time you want to change platforms. However, there is software (such as VMware Fusion) program where you can actually have both platforms open at the same time.

It prevents loops in a switched network with redundant paths.

If they both have wireless (Airport) cards, just set up one to accept wireless connections in the network and sharing control panels.
do this by: 1. with one of the macs, create a network. 2. with the other, search for wireless networks and find the one that was created. 3. chose that network to connect the two macs.

In disk utility select your volume. Then the blue info, you'll see Universal Unique Identifier.

The ntfs-3g program opens and does I/O to the block device (/dev/diskN) of the NTFS volume in question. Mac OS X does not have a VM buffer cache for block devices when they are accessed in this way. That's the most overwhelming factor, because both metadata operations and file data I/O boil down to read/writes by ntfs-3g to the block device.
Suppose we somehow automagically provided unified buffer caching for block devices by essentially making a disk look like a giant file. Even then, OS X and its buffer cache is really happy only when you do I/O that is in units of page size (4KB) and aligned on a page boundary. To get the most out of the I/O subsystem in OS X, ntfs-3g (or any other program for that matter) would really want to do I/O in multiples of 4KB.
For comparison, you should try writing to an NTFS disk image--you will see that it's considerably faster because you do have some caching in that case.
There are versions of ntfs-3g available that have additional user-space caching with drastically improved performance.

To connect the MacBook Pro's mini display port to the HDMI connections on a HD TV with audio requires a cable with an audio adapter.

Many USB webcams can be used with Mac OS X (See links below) which can be selected from the video sources listing within the software that you are using.

★ Remove the Python 2.7 framework
★ Remove the Python 2.7 applications directory
★ Remove the symbolic links in /usr/local/bin that point to this python version
★ If necessary, edit your shell profile file(s) to remove adding

With Mac OS X, you do not need to use such software. This function is part of Mac OS X. Follow the instructions in technical document 106282: "Mac OS X 10.0: Setup Assistant Does Not Accommodate DSL User Name and Password".

You can either use OS X's built-in PDF viewer (Preview) or, in the case of other file types, download a dedicated reader from Barnes & Noble or Sony.

You can't exactly edit pub files on a Mac, but you can convert the file to PDF.
