I was installing the updates for iTunes because I wanted to connect my iPhone to my Mac. However, I closed my MacBook prematurely since I didn't realise that they were still updating and now iTunes can't open again. How can I check its current updating progress (if it is at all)?
Launch the Mac App Store app and click on the Updates tab. The progress of any currently running update as well as any newly available updates are shown here.
With the Updates tab open, click on the Update icon in the apps toolbar to refresh the check for update.
Updates worked for me. I had Safari - can’t open the application Safari because it is being updated.
I went into App Store then updates and clicked update all. That seemed to clear the issue. Safari is back running Thank you
