Mac Interview Questions And Answers
1- How to start mac in safe mode?
You enter Safe Mode by shutting down your Mac and then starting it up while holding down the Shift key as soon as your Mac s monitor lights up. You can let go of the Shift key when you see the Apple logo and a progress bar. According to Apple, this is what happens during Safe Mode (and I quote):
It forces a directory check of the startup volume. You may see a progress bar on the screen during this check, and the computer may take longer than usual to complete its startup.
It loads only required kernel extensions (some of the items in /System/Library/Extensions).
In Mac OS X v10.3.9 or earlier, Safe Mode runs only Apple-installed startup items (such items may be installed either in /Library/StartupItems or in /System/Library/StartupItems; these are different than user-selected account login items).
It disables all fonts other than those in /System/Library/Fonts (Mac OS X v10.4 or later).
It moves to the Trash all font caches normally stored in /Library/Caches/com.apple.ATS/(uid)/ , where (uid) is a user ID number such as 501 (Mac OS X v10.4 or later).
It disables all startup items and login items (Mac OS X v10.4 or later).
Mac OS X v10.5.6 or later: A Safe Boot deletes the dynamic loader shared cache at (/var/db/dyld/). A cache with issues may cause a blue screen on startup, particularly after a Software Update. Restarting normally recreates this cache.
2- How to access recovery partition in Mac?
Hold down the OPTION key during boot and choose the Recovery option, or Hold down Command+R keys during boot to access the Recovery HD partition.
Here you can use Disk Utility, Time Machine, and restore the OS.
From the Utilities menu you can access Network Utility, use the Firmware Password Utility, and launch the Terminal, which lets you repair user home permissions, launch other apps, and perform other diagnostic tests.
Launch Terminal from the Utilities menu
To reinstall OS X from the Recovery partition on a Mac, you will need an active internet connection, that s because the recovery drive will download the remainder of the OS from Apple.
3- What is time machine & time capsule?
Time Machine is a piece of software that comes free with every Mac. When you set up and run it, the software makes a backup of your computer every hour, to any external hard drive. The first time it backs up it takes a while, because it s backing up everything on your computer. After that, it only backs up anything that s changed since the last time.
Time Capsule is a piece of hardware that is made by Apple and that you need to buy. It s two devices in one a wireless router, and a hard drive. So the wireless router lets you create a wireless network in your home or office. The hard drive serves as the destination drive for your Time Machine backups, so Time Machine can back up wirelessly over the air.
4- How do you uninstall applications in mac OSX?
Uninstalling applications in Mac OS X is very different than uninstalling in a Microsoft Windows environment because Mac OS X has nothing like the Windows Registry. While most Windows programs include an uninstaller that can be run through using the Add/Remove Programs control panel, no such feature exists in Mac OS X and so most users simply move application bundles to the Trash.
Applications will leave behind preference files, Preference files can be safely deleted. They are stored in the Preferences folder within your user's Library folder (~/Library/Preferences), or may also be stored in the system-wide Library located at the root of the system volume (/Library/Preferences/).
