Error copying files with Migration Assistant
Hello
I have a MacBook Air 13" mid 2011 with MacOS High Sierra (latest it can accept) witch I'd like to migrate to a MacBook Pro 13" 2015 with macOS Mojave (latest). Although process goes smoothly, it says ~ 3h required, after ~ 1h it stops with a copy error message (on both computers). If I click next it says migration complete, however may files and some programs were not copied, including some e-mail accounts. I have tried twice and got same error. From MacBook Pro to another MacBook Pro (both on macOS Mojave) works without any problem. What could be wrong? Do I have alternatives?
