There is no option for "DVD and CD Sharing" on a 2011 Mini because it doesn't have an optical drive to share. That option is available only on computers with an optical drive to share.
That option is used, on the other "donor" computer with an optical drive that you want to use/share. On the other computer you turn on "DVD and CD Sharing", allowing its optical drive to be shared. Then on the Mini you connect to it with "remote disc".
I believe you're thinking about the "DVD and CD Sharing" System preference in reverse; you activate it on the computer whose optical drive you want to use/share, not on the Mini without an optical drive.
See the following which explains how to set up and use remote disc: http://support.apple.com/kb/HT1777?viewlocale=en_US

When i try to buy mountain lion it says app store error (100) try later what should i do
when i try to buy mountain lion it says app store error (100) try later what should i do
Try here first > Mac App Store: "An unknown error occurred (100)" when purchasing
If that doesn't help, try the following:
Disable anti virus software.
Turn off the Firewall in System Preferences > Security (or Security & Privacy) > Firewall
If that doesn't help, open the Finder. From the Finder menu bar click Go > Go to Folder
Type this exactly as you see it here:
~/Library/Caches/com.apple.appstore/Cache.db
Click Go
Move the Cache.db file to the Trash.
Now here:
~/Library/Preferences
Click Go
Move these files from the Preferences folder to the Trash.
com.apple.appstore.plist
com.apple.storeagent.pllist
Now here:
~/Library/Cookies
Click Go
Move the com.apple.appstore.plist file from the Cookies folder to the Trash.
Empty the Trash, try the App Store. -
Verify disc and repair disc are not working. They give me the option to install the "installation disc" click on utilities>Disk utility from there. When I try this, there is no option to do this that I can find. Can anyone help me to do this?
You can't run Repair Disk from the Utilities folder. With 10.4, 10.5 or 10.6 put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
Or if you are running 10.7 Lion or 10.8 Mountain Lion, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7 or 10.8 partition.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive. -

Using Disk Utility for Boot Camp to work
I'm trying to install Windows 7, but Boot Camp gave me the old error message about having unmovable data and needed to use Disk Utility to format it as a Single Mac OS Extended (Journaled) Volume. So I backed everything up and am ready to go, but when I open Disk Utility and select my hard drive/disk, all the options under "erase" are grayed out. Any ideas?
Thanks!You can't format what you are using.
If you cloned your drive you would be able to boot from that; if you used another method and you don't have OS X installed on another hard drive, you have to use your DVD. -
I would like to have your kind support..Bootcamp windows7 freezing on start up and taking around 40 minutes to load. Mac mountain lion also taking around 5 minutes to load on start up.
My first step would be to get rid of "Norton protection". Boot from your OS 10.6 disc, navigate through your hard drivve and trash anything that is Norton. Empty the trash.
Next, run Disk Utility and ask it to repair the hard drive. -

i still have a warranty but it will be out in a week. i previously have a sound distortion problem with my mac for months and suddenly it just fix itself. what should i do? i'm worried that it will comeback and i dont have a warranty anymore.
JoBautista,
you still have the option (before your warranty expires) of purchasing an AppleCare Protection Plan, which will provide an additional two years of coverage. Once your warranty expires, you will no longer have the option of purchasing AppleCare. -
Why won't my Mac, with Mountain Lion installed boot up?
I had problems getting my Mac to boot so I made a Genius Bar appointment at my local Apple Store. The ran some tests and discovered a "disk i/o" error which they said indicated that my hard drive needed replacing. Hard drive replaced, brought it home, restarted, set up, Disk Utility run (permission checks out, disk checks out), Time Machine back up loaded and still all I get is the grey screen with the apple logo and the spinning wheel (not beach ball). Why won't it boot up? Any ideas???
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. -
I'm unable install mountain lion on my computer. Every time it says "OSX Mountain Lion couldn't be installed, because the disk \ is damaged and can't be repaired. Click restart to restart your computer and try installing again." So I press the only button listed as an option, it restarts, and the same screen comes up again. I can't make mountain lion go away...I've tried many times. What is wrong with my computer? It's stuck like this and I can't even get snow leopard back on there if I wanted to because I can't get away from the same screen. Please help : (
Insert your OS installer disk in the optical drive. Power the Mac down by holding down the power button. Then power back up and hold down the 'c' key so the MBP boots to the installer disk. From Disk Utility you should do a Repair Disk. If DU successfully repairs the disk quit the installer and reboot your Mac. You should update to 10.6.8 prior to upgrading to ML.

Then do your ML upgrade install. -

Resetting your Mac's PRAM and NVRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Reinstalling Mavericks, Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless. -

Below are the steps how i get Mac Mountain Lion(10.8.3 Build:12D78) kernel core dump from Apple Developer site:
1、Configuring the Server:
1)Creating the core dump directory:
server$ sudo mkdir /PanicDumps
Password:********
server$ sudo chown root:wheel /PanicDumps
server$ sudo chmod 1777 /PanicDumps
2)Activating the core dump server
server$ sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.kdumpd.plist
Password:********
3)Verifying the core dump server is active
server$ sudo launchctl list | grep kdump
Password:********
- 0 com.apple.kdumpd
2、Configuring a Client
client$ sudo nvram boot-args="debug=0xd44 _panicd_ip=10.***.***.***" （10.***.***.***

How do I get my mac mountain lion to stop saying, "You shut down your computer because of a problem?
My Mac Mountain Lion desktop computer keeps saying, "You shut down your computer because of a problem." How do I keep this from happening?
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the page that opens.
Select the most recent panic log under System Diagnostic Reports. Post the contents — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post shutdownStall, spin, or hang reports.
