The backup button in the iPhone summary in iTunes is greyed out. I tried it with a different phone and it was still greyed out but it works as soon as I switch users. I Used an iPhone 8 iOS 14.3 and an iPhone 6 Plus iOS 12.5.1 on macOS 10.12.6. Updating iOS had no effect. Both devices had the same outcome until I switched users. is there a way to fix it so I don't have to keep switching users to backup my phone?


I don’t think so... i think that’s because you don’t have enough space on icloud/don’t have paid account to resize space. And second thing - maybe you disabled backup in itunes on PC?

  • I’m sorry I don’t get what you mean. I have about 120 gb free on my Mac and my iPhone has 32 gb used. Although I doubt the problem is caused by a lack of iCloud space because it works on accounts with no iCloud accounts. I was also able to do backups until recently – Ahmed Shihabdeen yesterday
