so I'm opening a new topic as advised here.
Meanwhile I was able to set up a MySQL Database for Owncloud on a MAMP Server.
But I still can't figure out how to install APCu on MAMP since the Server is using a newer version of PHP than 5.4 so APC isn't working anymore(?).
Is it possible at all and can somebody tell me how?
I'm running Owncloud 9.1.1 on a MAMP Server 4.0.4 currently using PHP Version 7.0.10 (switchable to 5.6.25) and MySQL 5.6.28. All is freshly installed on a MacMini with OS X El Capitan 10.11.6.
It would help me a lot.
