Error compiling MKR WIFI1010

Dear all, Mac OS High Sierra, Arduino 1.8.10. Trying to compile for my MKR1010 and get the error that compilation did not work. It seems that either a library can't be found. Anyone know the cause of this? That would be great, Jitse

Arduino: 1.8.10 (Mac OS X), Board: "Arduino MKR WiFi 1010"

the installation of the boards package didn’t finish. reinstall it by installing an older version in Boards Manager and then updating back to latest
