When a user attempts to launch the application on an earlier version of OS X, it just simply refuses to launch.
Mac os system version mac os x#
If you compile an application with gcc 4.0, it can only be run on Mac OS X 10.3.9 and later. It works with Universal Binaries, Carbon and Cocoa, and all the way back to Mac OS X 10.0, and it doesn’t depend on the buggy LSMinimumSystemVersion feature from Apple. If not, an informative alert is presented to the user. I describe a better solution, using a boot-strapping executable to check the OS version, and only load the real application if the minimum OS version is satisfied. It doesn’t work in Panther at all, and it presents a very minimal and confusing error message on other versions of OS X.
Unfortunately, this feature is not very robust or user-friendly. The OS will then present the user with an error message if they try to run the application on an older version of the system. Supporting old OS versions is always a lot of work for application developers.Īpple provides a way for the developer to specify the minimum required OS X version for an application by setting the LSMinimumSystemVersion key of the ist file.
