Mac OS X will not run 68K code, so the Mixed Mode Manager will no longer serve any useful purpose. However, Carbon will support universal procedure pointers (UPPs) transparently, so you do not have to change them or remove them from your code. You may want to keep Mixed Mode Manager calls in your application to maintain compatibility with the current version of the Mac OS. Mixed Mode Manager calls from Carbon applications running on Mac OS 8 will function normally.
