[dba-users] Database compatibility win - mac

[tbudal]

I have got dissapearing tables in the database. I am working on a database together with a frend. He has a mac and I have a windows PC. When I create a database with tables, he can open it on his mac, but his tabels made on the mac just dissaperes when I opens his databases on my PC. Is there a workaround? Please help me if You can!
