Tell me that Final Cut pro 7 will work on Mac OS Mojave

The last OS that supported FCP-7 (Final Cut Studio 3) was Sierra, if I remember correctly:

tell me can I use Final Cut Pro 7 on Mac OS Mojave

You cannot on Mojave. Mojave does not support 32bit applications - which is what FCP-7 is.

If you want to use FCP-7, you need to run it on an Operating System that supports it - and hardware that is compatible with that OS.

There are still many people editing in FCP-7 on older computers.
