By default, the iTunes software automatically checks for updates every time the program is run. However, there can be instances when this feature isn't available. For example, the option to automatically check may have been disabled in the program's preferences, or your Internet connection might have dropped before or during an update check session. To manually check for iTunes updates, ensure your iPod, iPhone, or iPad is connected and run the program now. Follow these steps:
For the PC version of iTunes
- Click the Help menu tab on the main iTunes screen.
- On the pop-up menu that appears, choose the Check for Updates option.
For the Mac version of iTunes
- Click the iTunes menu tab on the main screen.
- Choose the Check for Updates menu option.
If you're having problems using the above method, or iTunes doesn't run at all, then you can also upgrade iTunes by downloading an up-to-date installation package. You can download the latest version from the iTunes website. Once downloaded, simply run the installation package to see if it fixes your problem.
