I am so frustrated right now. This new MacBook Pro is starting to feel like an endurance test. And I'd bet I have a higher than average tolerance for the need to overcome technical problems. Config is a 2016 15" MBP 2TB. I am new to Mac OS; coming from a Thinkpad / Windows. I experienced the Time Machine problem where the MBP rebooted constantly when attaching an external hard drive. Just installed the latest Mac OS that fixes that problem. My guess is my Time Machine problems are my fault because I can't figure it out, but the disappearing mouse cursor makes figuring it out impossible. Problems: - When I launch Time Machine with a new Seagate 4TB Backup Plus drive attached, I only see a screen like this. No mouse cursor ever becomes available to me. I double-tap, triple tap, do all sorts of gestures. No mouse cursor. Just the screen. I try to guess menu commands. Nothing works. I reboot. Is this how it's supposed to work? Is time machine automatically doing something when I'm frozen at that screen? 2) When I blamed the drive for these problems, I was using a new Western Digital My Passport 3TB Ultra. So I bought the Seagate instead. (before reading here that it was MacOS problem, not the drive) Now - with the Seagate, I'm looking for a format command or how to make it work with the Mac. I don't see a format command in Disk Utility. Just Erase. I did eventually install the Seagate app shown below, It's supposed to let it work with Windows. I installed it to see if that would fix the mouse cursor problem. It doesn't. I don't really care if the drive works with Windows or not. I just want to dedicate that drive for MBP backups. Now after I rebooted and re-launched Time Machine and I see this but still my mouse cursor has vanished. I have > 1 TB of data on the MBP now. I do not think I've had a drive attached long enough to do a full Time Machine backup. Does what you see on that screen mean that my Mac thinks it has full backup at those intervals on the right side?
