Hi Yoni,

If you used the standard .dmg installer, you could try opening a Terminal 
window and executing the following commands:

echo $SHELL

If the output says: /bin/bash then do

source /Applications/ccp4-6.3.0/bin/ccp4.setup-sh & ccp4i

If the output says: /bin/tcsh or /bin/csh then do

source /Applications/ccp4-6.3.0/bin/ccp4.setup-csh & ccp4i

If this works, then your installation is probably okay, but check the following 
files in your home directory to make sure you are sourcing the ccp4 version you 
want to use (note: some of these may not exist, thats okay):

.profile
.bash_profile
.bashrc
.cshrc
.tcshrc

Hope that helps,
Kip
