Question: last Update WIN10 I use with Bootcamp now prevents to start with or switch over to macOS High Sierra
I have a Macbook Pro late 2016 with touchbar. I am using macOs High Sierra and Win10 via Bootcamp. Everything was fine until the last WIN10-Upgrade (KB4048951, 404954 and 4049011). Strating from then WIN10 somehow prevents the Mac from starting in MacOS rather than in WIN10. If I click on the Boot Camp icon and then choose "restart in macOS" an alert window informs that the system can't find the startup volume of macOS.
I asked the Apple Support and after several other tries ,we started the disk repair via cmd+R at start. The system was fond and I could access macOS.
But when I then switched back to WIN10, again WIN10 prevents macOS from starting.
At the end Apple support adviced me to reinstall macOS, what I did this morning.
Again macOS was starting fine, but again switching to WIN10 it prevents to get over to macOS.
I then tried to restore WIN10 to the point previous to the last updates, but nothing changed.
Does anybody have a clue and solution?
Thanks in advance for your suggestions.
