For issue 1
Select the file you are trying to move, then choose Get Info from the File menu. If the Locked box is checked, deselect it, then try moving the file again.
If the item you are trying to unlock is a folder,use these steps:
- Open Terminal (/Applications/Utilities).
- Type this, followed by a space: sudo chflags -R nouchg
- Drag the folder you would like to unlock into the Terminal window.
- Press Return.
- Enter your password and press Return.
If you have attempted to unlock a file in the Finder but it is still locked, follow these steps to remove the system immutable bit from affected files, which can cause this issue.

If the issue persists, see "Mac OS X: Troubleshooting Permissions Issues"
For issue 2
Mac OS X restricts access to some folders (including Applications, Library, and System) to preserve the integrity of the operating system and user data.
You can easily determine if an area has restricted access. Mac OS X 10.2.8 or earlier: Select the folder in a Finder window (not the desktop), then choose Show Status bar from the Finder's View menu. The status bar appears near the top of each Finder window. When in a restricted location, a pencil-with-slash icon is visible in the status bar; Mac OS X 10.3 or later: Open the folder and look in the window's lower left corner. If you see a "a pencil-with-slash icon", you know it's a restricted access area.

If an item was removed from the Applications folder and cannot be moved back
With Mac OS X 10.3 or later, you should be able to drag the item back into the Applications folder. If a dialog box appears with an Authenticate button, click on Authenticate and enter the name and password of an admin user.
Otherwise, try one of these solutions:
Option 1 - If your computer can start from Mac OS 9, start up from a Mac OS 9 CD or volume and return the item to its proper location. It is normal for the file structure of the Mac OS X disk to look different when started up from Mac OS 9.
Option 2 - If the application has been deleted from your volume, start up from your Mac OS X CD and perform a complete reinstallation (not erase-installation) of Mac OS X.
Tip: This option is useful for replacing removed Mac OS X items, but it will not remove an undesired item in most cases. To remove an undesired item, use Option 1 or Option 3. You should not reinstall an earlier version of Mac OS X (from CD-ROM) over a later version of Mac OS X (after system software updates have been installed).
Option 3 (Advanced) -
- Open Terminal (/Applications/Utilities).
- Type: sudo chmod 775 /
- Press Return.
- Enter your password and press Return.
- Using the Finder, move the item(s) to the desired location.
- In the Terminal, type: sudo chmod 1775 /
- Press Return.
If the issue persists, use Disk Utility on the volume. See "Mac OS X: About Using Disk Utility and fsck for File System Maintenance".
If an item was installed by a user and cannot be removed
Refer to the steps under "If an item was removed from the Applications folder and cannot be moved back" above.
