Top MAC OS Interview Questions
Q – 1 What is MacFUSE?
Ans- MacFUSE is software that allows you to write arbitrary file systems as user-space programs. You can think of it as a library for easily developing Mac OS X file systems. Another crude way to look at this would be to think of MacFUSE as something that makes Mac OS X work like a microkernel for the purpose of writing/running file systems.
MacFUSE has two major components: an in-kernel loadable file system and a user-space library (libfuse). The in-kernel file system is specific to Mac OS X and is not based on Linux FUSE. (Some of its code is based on the FreeBSD implementation of FUSE.) The user-space library (libfuse), which provides the developer-visible FUSE API, has numerous Mac OS X specific extensions and features.
Q – 2 How to take screen shots on the Mac?
Ans- To take a screen shot with Mac OS X hold down the Command (cmd) key and the shift key and either the number 3 to take a shot of the whole screen or number 4 to change your pointer to cross-hairs that can be dragged across a section of the screen to capture just tat part.
With the cmd+shift+4 option you can put your pointer over a window and press the space bar to capture that window,
In the Utilities folder which is in the Applications folder is software called Grab which does the same thing but also allows for a delayed capture which gives you ten seconds to arrange your screen before taking the shot.
Q – 3 How to transfer files from mac powerbook to external hard drive?
Ans- First, make sure that your external hard drive is USB capable. If it uses firewire, then that might be the issue. If it is USB capable, then plug it into the power book. Wait at the most 1 minute for it to recognize the external hard drive. If it does not appear on the screen, you may want to try and plug it in on a second computer.
If it doesn’t show up on a second computer, the hard drive may have a problem/bug. If it does show up, then drag the selected files onto the hard drive. If it says you can’t, then there probably isn’t enough room on the hard drive to store the files. That is about all that can be explained to you from the information given.
Q – 4 How to use Internet Explorer 7 on Mac OS X?
Ans- First go to Safari Preferences>Advanced and check the box to show the Develop menu.
Next open the Develop menu and go to User Agent and choose IE. Should probably use the latest, 9.0. Don’t forget to set it back to the default when finished with that form if it works.
Q – 5 Where is the print screen key on a Mac?
Ans- There is no print screen key for Macs, however, there are several key combinations for taking screenshots based on what you want to do with the screenshot.
I personally use Cmd+Shift+4, and select what I wish to take a picture of, or if i want to take a picture of a window, I press space. This will save the screenshot on your desktop.
Q – 6 How to delete files in Mac OS X?
Ans- Firstly, you drag the file to the trash. Then, just empty the trash by right-clicking and then selecting “Empty Trash”
The trash is similar to the recycle bin in Windows.
Q – 7 What is Macintosh’s newest operating system?
Ans- The latest version of Mac OS X is OS X Yosemite.
Q – 8 Suppose if you delete something from the registry editor does it uninstall?
Ans- Registry is like a database which stores windows information.
all you are seeing in your system is controlled by registry.
registry also stores location of applications and processes. so if you delete an application entry from registry than you cannot see it in Appwiz.cpl.
I suggest don’t make changes in registry if you haven’t much knowledge about it. It May corrupt your windows.
Q – 9 When to update mac software to keep files?
Ans- On update user files are not effected (mostly). Applications (~/Applications or /Applications) files and user files (~/Library/Application Support) are kept in different locations. Most of the times only application files are updated and only developer decides what should happen with user files.
If older user files are not compatible anymore and new version of application can’t convert your user files to newer version, configuration files of that application will be damaged and removed. Application will start as first time and reconfiguring will be needed (if required at all). For instance Skype requires login information.
Other files not related with application is touched.

Q – 14 How to make Eee PC running Linux look like Mac OS X?
Ans- The Xandros system does not allow this extent of modification. You would need to install another Linux distribution on the Eee.
Two distros that have a GUI similar to that of Mac OS X are gOS and Dreamlinux. gOS is designed for low-powered devices like the Eee, so it should be a good fit. Dreamlinux is not tailored for the Eee, but has low system requirement.
Q – 15 Tell me what is root port in spanning tree protocol?
Ans- Based on the location of the root bridge, the other switches determine which of their ports has the lowest path cost to the root bridge. These ports are called root ports, and each switch (other than the current root bridge) must have one.
Q – 16 Tell me what is non designated port in spanning tree protocol?
Ans- Non-designated ports have no role to play and hence are put into blocking mode.
If it helps, consider root/designated/non-designated as port roles, and forwarding/blocking as port states. Every bridge has a root port, and every link has a designated port.

Q – 20 Can you please explain the difference between Mac OS X and Windows?
Ans- OS X is a BSD Unix based operating system with a GUI which is more user friendly than Windows for many users. The OS allows for permissions based accounts, and has better access controls to limit the spread of malicious software (yes, there are viruses and proof of concepts which target Apple software), and protects the system folder from write actions unless a user has administrative privileges.
The ease of use is often cited as a primary reason for educational institutions and art related business to defer to Apples.
Windows is prevalent in business environments, and has differing architectures based upon which flavor is installed (there are vast differences between 3.11, 95, 2000, XP, Vista, and 7) and the variations would best be researched on a product information site.
Because of the popularity of Windows, malware and viruses are numerous, and an antivirus program is often the bare minimum that a user must use to protect their computing resources and data.
No matter the operating system, a best practice to follow is to always work from a user account with limited privileges and only do upgrades and installs from within the administrative account’s workspace.
Q – 21 Tell me do Macs have USB ports?
Ans- Apple’s original 1998 iMacs were the first computers to solely use USB ports and the popularity of the computer expanded the market for USB peripherals. USB ports remain a feature of all Macs to this day day.
Q – 22 What is Mac OS’X?
Ans- OSX is a Operating system derived from BSD, and thus unix…
Unbuntu can be skinned to look like and behave like OSX (I did that in about 15 minuets)
OSX in a sense is a Desktop environment, but is very resource intensive in contrast to openbox.
(If you do it right, a computer running Linux and openbox can boot to login in 15 seconds)
(Linux is a derivative of UNIX)
So basically, OSX is a way for you to have your computer do the work you want it to do.

Q – 48 Why ntfs-3g’s write performance so poor with MacFUSE on OS X?
Ans- 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.
Q – 49 How to find mac 32 digit system id?

Q – 51 Explain the purpose of the Spanning Tree algorithm?
Ans- It prevents loops in a switched network with redundant paths.
Q – 52 How to connect a windows xp to a mac os x?
Ans- 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.
Q – 53 How to fix unresponsive Mac OS X?
Ans- 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.

Q – 55 What you do suppose if DSL/PPPoE software does not work with Macintosh computers?
Ans- 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.
Q – 56 If after installing ntfs-3g, Boot Camp volume stopped showing up in the Startup Disk preference pane. Is reinstalling Mac OS X, Boot Camp, and Windows the only recourse?
Ans- 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.
Q – 57 Can you please explain the difference between Windows and Mac OS X?
Ans- 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.
Q – 58 What is PPPoE?
Ans- 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.

Q – 62 What is DSL?
Ans- 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.
Q – 63 What is Mac OS?
