Hello everyone,
I recently got a new computer last month (refurbished) MacBook Pro 13.3 inches 2020 and I have updated the new Mac OS Big Sur on my computer. After it was completed, I signed into my MacBook Pro and I keep getting a message saying "The disk “Macintosh HD - Data” can‘t be unlocked."
Best Regards,
Sam
MacBook Pro 13″, macOS 11.0
