i used the Cider install on my last 3 mac laptops, all worked flawlessley...
and there is even and easy install via MacPorts1
install Xcode 4.2
-(we are not using the current version) https://developer.apple.com/downloads/index.action#
- sorted by date Nov 29, 2011)
once installed run Xcode to make sure it is fully installed. 2
install MacPorts https://distfiles.macports.org/MacPorts ... 7-Lion.dmg3
open the Terminal.app -(found in /Applications/Utilities/)
type the following code into the Terminal. you will be asked for a password.
sudo port install mystonline-cider
after a short wait you should have "Myst_Online_(Cider).app" installed into /Applications/MacPorts/
--edit: sorry i got that a little wrong... MacPorts doesn't work with the newest version of Xcode... > Fixed step 1
--edit: if MacPorts has been installed for a while you might want to update it "sudo port -v self update"
