Mac Backup & Upgrade Help Needed

Job ID: 38172142

Budget: €30 – €250 EUR

I'm facing technical challenges with my Mac and need professional assistance to resolve them.

1. Backup Problem: The backup fails due to two disks having the same name. I need a professional to guide me on how to rename one of the disks so the backup process can proceed smoothly.

2. Upgrade Problem: The upgrade process initiates, the download is completed, the system restarts but it never completes. I need support to identify the issue and help in successfully completing the upgrade.

I've already restarted the Mac, but the problems persist, so a deeper understanding and technical intervention are needed.
