-45054

I'm experiencing the same problem. I have performed Repair Disk Permissions, restarted, restarted into Safe Boot and the error continues. No disk problems.

The log shows the following errors on each launch of iTunes

10/23/13 8:53:12.614 AM iTunes[334]: AVF error: flow_KE1 acceleratorCreate 1

10/23/13 8:53:17.195 AM iTunes[334]: BUG in libdispatch client: kevent[EVFILT_WRITE] delete: "No such file or directory" - 0x2

This is a Disk Permissions error that can be resolved with Disk Utility "Repair Disk Permissions" in most circumstances.

However, if you are running OS X Server, this requires changing File Sharing permissions for the Shared Folder "Shared". The user running iTunes requires a minimum of Read Only access.

I tried repairing permissions and it didn't work. Tried it from the Install Disk at start up and it STILL didn't work. What's next?

The issue is access to the /User/Shared folder (usually Macintosh HD -> Users -> Shared).

Do a Get Info on this folder, check to make sure your username has a minimum of Read access to this folder. If not, change the permissions for this folder.

If you are running OS X Server, this requires changing File Sharing permissions for the Shared Folder "Shared". The user running iTunes requires a minimum of Read Only access.

+1 on the Solution.

I ran into this after upgrading from Lion to Mavericks. I couldn't figure out for the life of me why iTunes was crashing. After I deleted iTunes, re-installed from the stand-alone image from the Apple website, and updated iTunes with 11.1.3 it was still crashing at launch with the ~45054 error.

I ran Repair Permisisons form the Disk Utility and iTunes fired right up without a problem.

Thanks!

Thanks wmark! Mystery solved. 😀

Sounds like i have the same problem as well, I'm really new to Macbooks so I'm just curious how do i do it? because the itunes is closing so much i cant access anything on it, could someone please write step by step on how to do it? like from the start please and thank you

Open Disk Utility in Applications > Utilities.

Click repair permissions.

Thank you!!!! this worked for me!

Thanks WMark!! Disk Permissions did not work for me, but changing the permissions for the /User/Shared folderreally helped me out. Great!

May be same like my reference?

Re: An unknown error occurred (-45054)

Hey, I've done everything suggestedin this thread and I'm still having this issue. I'm trying to purchase iTunes Match and I keep getting 45054 ... grrr

Try this friend:

ERROR 45054 en iTunes

Este error que no permite que iTunes accese a las descargas y actualizaciones de las Aplicaciones ahí manejadas en sincronización con iPad o iPhone…se genera por un fallo en la restauración de la carpeta COMPARTIDA que está en:

RAIZ\Usuarios\Compartido\adi

Esta carpeta “ adi “, se le observará que presenta un circulo rojo con un signo MENOS en el interior, lo que aparentemente indica que, el usuario de la cuenta en uso, no tiene privilegios para modificarla.

Así de que simplemente, se debe posicionar el cursor sobre la carpeta adi

1) abrir la ventana contextual con el mouse (o dos dedos en el mouse pad)

2) Elegir VER INFORMACION

3) En la esquina inferior derecha de la ventana, se observa un candado CERRADO

4) Click sobre el candado y proporcionar la CONTRASEÑA de Usuario

5) Se verá que a la izquierda del candado aparece “ Privilegio “ y…

sólo en SISTEMA se lee Privilegio: Leer y escribir y en los otros usuarios: DENEGADO

6) Se les debe modificar el privilegio de DENEGADO a Leer y escribir a las otras cuentas

7) Se hace click de nuevo sobre el candado y…..PROBLEMA RESUELTO

(al menos en OS X 10.9.3 Mavericks me funcionó bien)

45054 ERROR in iTunes

This error does not allow iTunes ACCESS, downloads and updates for the Apps there managed in sync with iPad or iPhone ... is generated by a failure in the restoration of the SHARED folder " adi ":

ROOT \ Users \ Shared \ adi

This folder "adi", you will notice that has a red circle with a minus sign inside, which apparently indicates that the user's account, does not have privileges to modify.

So it simply, you must position the cursor on the folder adi

1) Open the pop-up window with the mouse (or two fingers on the mouse pad)

2) Choose REFER

3) Observed a lock in the bottom right corner of the window, CLOSED

4) Click on the lock and provide the User Password

5) You will see that on the left lock "Privilege" appears and ...

only reads SYSTEM Privilege: Read and Write and other users: DENIED

6) Must be modified DENIED them the privilege to read and write to the other accounts

7) We click on the lock again to close it...and...PROBLEM SOLVED

(At least on OS X 10.9.3 Mavericks it work for me)
