Love this game, zoom can be fixed manually, El Capitan update is still missing
Late 2015 iMac - in overall, the game runs pretty well. Zoom can be fixed manually (!!!). Join the facebook group C&C Generals Mac App Players and you will find posts how to fix the zoom. Nonetheless, if you upgraded your system to El Capitan, invitations do NOT get through; however, yosemite invitations do get through! Players are still waiting for an update to fix this issue. If you do fix the zoom manually, the game eventually crashes. This happens once in a while-not too often.
If you insist to host games for you and your friends, you will need to create a backup of your system, do an internet-recovery, create a second partition, install yosemite on your new created partition, and use time machine backup for your normal first partition.
