KM won't work on my Mac Book Pro but work on desktop

KM works great on my desktop but most of the macros won't work on my 2015 Mac book Pro. Both are running the same operating system and they both are the most recent version of KM. Some of the simple ones work but not the more complicated ones. Very frustrating. Any ideas? Thanks!

Any time a macro “wont work” (ie, does nothing), the starting point should be the Help ➤ Assistance window, and selecting Something expected is not happening and following the instructions there to see what issues Keyboard Maestro can find as to why your macro might not work.
