I had a similar problem with Mamp Pro. For me it turned out the correct .idb-files were not located at "Applications/Mamp...". So taking a closer look at the error-log it showed me the files were located at "/Library/Application Support/appsolute/MAMP PRO/db". As I had problems with a database I wasn't using anymore, I just tried to delete the corresponding folder and it worked out. The next step would have been to delete the files already mentioned by the author.

• innodb_index_stats.frm
• innodb_index_stats.ibd
• innodb_table_stats.frm
• innodb_table_stats.ibd
• slave_master_info.ibd
• slave_relay_log_info.frm
• slave_relay_log_info.ibd
• slave_worker_info.frm
• slave_worker_info.ibd

But as mentioned deleting the databasefolder worked out great.
