About your specific issue, it could  be related to a misbehavior of your display .

You could try  a silent installation , using command line : 

----------------

cplex_studio1280-osx.app/contents/MacOS/cplex_studio1280-osx -l en -f ./installer.properties  

where the content of the installer.properties  is
<<<<
INSTALLER_UI=silent
LICENSE_ACCEPTED=TRUE
USER_INSTALL_DIR=<my.install.dir>
>>>>

----------------

Thank you for your reply,

I tried it and it did not work. I am getting following message:

Hi , 

Which  Operation System language are you using ?

For  some new and not officially supported OS by the application, the usage of English as the Operation System language could be a workaround.

Bonjour,

I had the same problem (osx10.13.3 macbook pro mid 2015, file système APFS Case Sensitive). The proposed command line would be great but give me the same error as mentioned by scipiotc.

However I've been able to manually install cplex-12.8 by decompressing some archives deeply hidden inside the cplex_studio1280-osx.app installer. Here is the post with the detailed method (It should probably be adapted for other cplex versions...) :
