Migration Assistant fails silently
I'm trying to transfer my old MacBook Pro to my new MacBook Pro. I've been using the Migration Assistant for the last couple of nights. First I tried over Ethernet and tonight I tried with Thunderbolt.
I can see that files started transferring but without success. All I get is an error occurred, without any further information.
I also tried to set my old MBP in Target Disk Mode, but then it didn't appear in Migration Assistant.
Please help me, I'm getting desperate here.
Thanks in advance!
MacBook Pro 13", 10.14
