Hello,
sorry if this question has been asked already - at least google din’t find a sufficient answer :(

I have been upgrading a MacOS 10.6 server to serverv5, which is MacOS 10.11

I was running before: mysql-5.5.40-osx10.6-x86_64

upgrade has been always a no-brainer: download the dmg and run the installer

but now after upgrading to mysql-5.6.31-osx10.11-x86_64
mysql is crashing:
09-03 18:23:07 51218 [Note] IPv6 is available.
2016-09-03 18:23:07 51218 [Note] - '::' resolves to '::';
2016-09-03 18:23:07 51218 [Note] Server socket created on IP: '::'.
2016-09-03 18:23:07 51218 [ERROR] /usr/local/mysql/bin/mysqld: Can't create/write to file '/usr/local/mysql/data/mysqld.local.pid' (Errcode: 102 - Operation not supported on socket)
2016-09-03 18:23:07 51218 [ERROR] Can't start server: can't create PID file: Operation not supported on socket

I set the bind to the local ip, but it doesn’t change anything

2016-09-03 19:16:08 2125 [Note] - '192.168.2.10' resolves to '192.168.2.10';

2016-09-03 19:16:08 2125 [ERROR] Can’t start server: can't create PID file: Operation not supported on socket

same happens with local ip:
2016-09-04 15:25:19 85518 [Note] Server hostname (bind-address): '127.0.0.1'; port: 3306
2016-09-04 15:25:19 85518 [Note] - '127.0.0.1' resolves to '127.0.0.1';
2016-09-04 15:25:19 85518 [Note] Server socket created on IP: '127.0.0.1'.

2016-09-04 15:25:19 85518 [ERROR] Can't start server: can't create PID file: Operation not supported on socket

the socket is created but then something goes wrong.

as I couldn’t find anything, which really would relate to the problem, I guess I miss something here.

thanks for any input
Matthias
