Hi

I tried the above running each step manually on mac. I also appended --force to mysql_upgrade. However, I received the following warning message on my phpmyadmin

Warning in ./libraries/dbi/DBIMysqli.class.php#258
 mysqli_query(): (HY000/1682): Native table 'performance_schema'.'session_variables' has the wrong structure

Backtrace

And on my command line, I received the following

You might need to run the commands separately and refer to your correct path and mysql version. I did the following after manually downloading and installing mysql 5.7 (It appears under System preferences)

I ran the following commands.
cd to the location of your new mysql installation . i.e

cd /usr/local/
sudo rsync -av mysql/bin/* /Applications/MAMP/Library/bin/ --exclude=mysqld_multi --exclude=mysqld_safe
sudo chmod -R o+rw  /Applications/MAMP/db/mysql56/
sudo chmod -R o+rw  /Applications/MAMP/tmp/mysql56/
sudo chmod -R o+rw  /Applications/MAMP/tmp/mysql/
ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock
sudo chmod -R 777 /Applications/MAMP/db/mysql56
sudo chmod -R 777 /Applications/MAMP/db/mysql56/
/Applications/MAMP/Library/bin/mysql_upgrade --user=root --password=root --host=localhost --port=3306
