Hi!
I'm just in the middle of transferring from one Mac to another and I've just downloaded Keyboard Maestro here. When I open up the system preferences and go into privacy settings I can see that KM is not in the "Automating" tab, like on my old mac. So I've wanted to ask, how can I force KM to ask for permissions? It already has the screen recording and accessibility permission. Also, if you know an easy way to share all of the macros from the old Mac to here and would share it here, I would be thankful!
Howdy, in my experience Keyboard Maestro asks for those permissions whenever you first run a macro that requires them (I could be wrong, it's been awhile since I had to setup Keyboard Maestro on a fresh machine).
As to the other question, you can select all of your macro groups and then export them as a macro library from the File > Export menu, or if you have syncing turned on you can click on File > Reveal Macro Sync File and use open that file on the new machine.
I for one have syncing turned on and keep that sync file stored in Dropbox so both my iMac and MacBook have identical libraries. There's a fair amount of information published on this so a cursory search here will no doubt net you some good info.
But don't hesitate to reach out if you have more questions.
