iTunes crashes everytime i open it

iTunes won't play nicely with a NAS. Put everything back where it came from. Use an external drive instead. You can use the NAS as a backup for the primary copy. See Make a split library portable and ensure both the library files and media go onto the external in a portable layout.

Option-start iTunes and create a new library. Will it do that without crashing?

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 and start typing the name.

Step 1

For this step, the title of the Console window should be All Messages. If it isn't, select

SYSTEM LOG QUERIES ▹ All Messages

from the log list on the left. If you don't see that list, select

View ▹ Show Log List

from the menu bar at the top of the screen.

In the top right corner of the Console window, there's a search box labeled Filter. Enter the name of the crashed application or process. For example, if Safari crashed, you would enter "Safari" (without the quotes.)

Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name, may appear in the log. Anonymize before posting.

Step 2

In the Console window, select

DIAGNOSTIC AND USAGE INFORMATION ▹ User Diagnostic Reports

(not Diagnostic and Usage Messages) from the log list on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of crash reports. The name of each report starts with the name of the process, and ends with ".crash". Select the most recent report related to the process in question. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.

I know the report is long, maybe several hundred lines. Please post all of it anyway.

If you don't see any reports listed, but you know there was a crash, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.

In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)

Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

When you post the log extract or the crash report, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

Step 2?

iTunes crashes overtime I try to sync a device ..

26/06/15 4:12:30.000 pm kernel[0]: iTunes (map: 0xffffff8037ce70f0) triggered DYLD shared region unnest for map: 0xffffff8037ce70f0, region 0x7fff8de00000->0x7fff8e000000. While not abnormal for debuggers, this increases system memory footprint until the target exits.

Any assistance would be much appreciated as this issue is a real menace.

Read this whole message before doing anything.

Back up all data.

Quit iTunes if it’s running.

Step 1

Hold down the option key and select

Go ▹ Library

from the Finder menu bar. Move the following items from the Library folder to the Trash, if they exist:

Application Support/SyncServices

Caches/com.apple.iTunes

Caches/QCCompositionRepository-com.apple.iTunes.cache

Containers/com.apple.BKAgentService

Saved Application State/com.apple.iTunes.savedState

Leave the Library folder open. Try iTunes again. If it works now, stop here. Close the Library folder.

Step 2

If you still have problems, quit iTunes again. Go back to the Finder and move the following item from the open Library folder to the Desktop:

iTunes

Note: you are not moving the iTunes application or the iTunes library. You’re moving a folder named “iTunes.” Test. If iTunes now works, delete the iTunes folder on the Desktop. Otherwise, quit iTunes again. Put back the folder you moved, overwriting the newer one that may have been created in its place, and continue.

Step 3

In the Preferences subfolder, there may be several files having names that begin with either of the following strings:

com.apple.iTunes

com.apple.mobile.iTunes

Move them all to the Desktop.

Also in the Preferences folder, there's a subfolder named "ByHost". Open it and do the same thing.

Test again. This time iTunes should perform normally, but your settings will be lost. You may be able to put back some of the files you moved to the Desktop in this step. Relaunch and test after each one. Eventually you should find one or more that causes iTunes to malfunction. Delete those files and recreate whatever settings they contained.

If the issue is still not resolved, quit iTunes again and put all the items you moved to the Desktop back where they were. You don’t need to replace the items you moved to the Trash. Stop here and post again.

If you later decide that you don’t like the results of steps 2 and 3, you can undo them completely by quitting iTunes and restoring the items you deleted in those steps from your backup.
