This is on Snow Leopard.

When I plug in my iPhone or iPad into iTunes and click the "Check for update" button, it puts up a dialog box asking me to choose a file. This is supposed to happen if you press option while clicking Check for Update [which I'd done once], but now it happens every time. Restarting iTunes makes no difference, and it happens both on iTunes 10.4 and 10.5.

How can I get iTunes to check with Apple for an update? Thanks.

I am on Lion but had a similar problem. Based on info here: , which says that 'the file selector dialog only appears only if automatic detection of iOS updates is turned off', I tried removing ~/Library/Preferences/

This fixed things for me. Quit iTunes before you do this, and move the plist file somewhere so that you can restore it if necessary. (It may be possible to change this preference setting without messing with the plist; however, I couldn't immediately spot where to do it in the UI).

You don't want to delete the whole plist, because you'll lose all your preferences. Just change the single flag by running the following in Terminal:

defaults write disableCheckForUpdates -bool NO

I've had the same problem updating my iPhone OS with iTunes on Windows 7. Editing/deleting the .plist doesn't help. I had to edit the Windows registry manually. The following pages were useful:

HKEY_LOCAL_MACHINE\Software\Apple Computer, Inc.\iTunes[SID]\Parental Controls\AdminFlags

Setting the AdminFlags to 0x0000ec00 worked for me.

As @kartick noted

defaults write disableCheckForUpdates -bool NO

Works perfectly on my Mac (currently running OS X Yosemite 10.10.3) just remember to shutdown iTunes first. This is ideal as you do no loose any of your preferences. Think scalpel vs battle axe where battle axe is deleting the entire plist preferences file. I am running iTunes btw.
