Shukaku: A not-so-great-but-understandable translation of the OP's post (taken from Google Translate):
"Hello, need help for the installation of play on mac explanations because I do not know how to install the extension of the second cd.
Moreover this is more Sierra manages I learned that it was gog.com and I do not know how to get the updates.
I am new: /"
Which version are you using? The GOG.com version is only for Windows users and is not listed to support alternative operating systems.
If you are using the CD version, then you need to ensure you've installed the base game of Pharaoh first (recommended to use the "Full" install option) and then install Cleopatra as an addition. Be aware that you may find the game will crash when Cleopatra is installed (as a CD version that is) and it is not as stable as Pharaoh as a standalone.
Sidenote: Many members here are primarily English speaking, so you'll find it easier to get support when using English. If it's not your first language, that's fine, but it may make it difficult for members to support you. :)
Thank you for your reply, I have installed the first pharaoh cd full version and then I installed Queen of nil.
By cons when I put the game on the way he said: insert the cd Queen of nyl !! the cd is still in the drive !!
