Installing CS4 and file system is not supported

[Karalstar]

Hi, I am trying to instal ps (CS4) on my new MacBook Pro and I keep getting a system requirements error saying this software cannot be installed bc the file system of the setup volume is not supported. What does this mean? And how do I fix this?

it means you have a case-sensitive hd or incompatible os (or both).  Adobe error "Case-sensitive drives not supported" or similar install error | Mac OS

You also may never be able to install CS4 on a Mac running Sierra

CS6 and earlier programs have not been tested and will not be updated for Mac El Capitan/Sierra

-which means that you try to use CS6 and earlier at YOUR risk of having problems due to Apple updates

-Apple did not maintain backward compatibility with old programs in El Capitan or Sierra

--Adobe has a workaround to Apple's problem of not maintaining backward compatibility

It could also be a change in Sierra's settings blocking the CS4 installer and generating a misleading error message. You may need to re-enable the Anywhere option in Sierra's Security & Privacy settings.

Also Installing Creative Suite on macOS 10.12 (Sierra)  has helped many people.

Good afternoon

If you are not very technical, this may be beyond your skills to fix safely - the risk of losing everything would be very high. CS4 all the way to the current CC2021 will not install on a case sensitive filesystem.
