Help!: The iphone cannot be synced. You do not have the privilege to make changes

[dom87]

Help! This is the third forum that i visit. I hope can get answers from here.

I synced my iphone4 to a window PC before i get a mac recently.

So, when i try to sync my iphone 4 to mac.
I was told that "the iphone cannot be synced. You do not have the privilege to make changes".

1. i clicked store> authorize this computer. =failed.
2. restart mac. =failed.
3. reinstalled itunes. = failed.
4. restored iphone4. =failed.

Then,

I do logged in as admin.
I changed all the related folders' sharing/permissions to "read & write" for admin, me and everyone.

Then,

i checked the permission, enclosed to all folders.

But still cannot be snyced for the music and photos.

Might add some more info.

You restored the phone on the Mac and the restore failed or the restore worked but you still can't sync?

Changed permission on what folders - where?

Is this a jailbroken iPhone?

What Mac do you have, what version of OS X and what version of iTunes?

Have you authorized iTunes on your Mac?
