My solution to the problem:
Apple product counts:
df = playbook_events.merge(playbook_users, on = 'user_id', how = 'left')[['user_id','device', 'language']]
df['is_apple'] = df['device'].apply(lambda x: x.lower() in ['macbook pro', 'iphone 5s', 'ipad air'])
apple = df[df['is_apple']]
apple = apple.drop_duplicates('user_id')
apple = apple.groupby('language', as_index = False)['device'].count()
df = df.drop_duplicates('user_id')
df = df.groupby('language', as_index = False)['device'].count()
df = df.merge(apple, on = 'language', how = 'left', suffixes = ['_total', '_apple']).fillna(0)
df.sort_values('device_total', ascending = False)
