Downloading SysEx/data dump from DrumKat to MacBook Pro

There are apps that will allow you to receive and send sysex data between your Mac and your MIDI gear.

I can't vouch for the performance of any of these, but they are out there. I found a couple with a quick google search. Here's one: https://www.snoize.com/SysExLibrarian/

Also, Logic Pro itself can receive and send sysex data from and to your MIDI devices, though the process is not a straightforward as it probably could be. I'm sure that once you've figured it out it's probably not terribly difficult. You can store your sysex data within a Logic project and recall it at any time.

Check out the Logic Pro User Guide for Mac - Apple Support online for guidance.

Use the search feature once you are looking at the website.

I've been using it for years with several devices including DrumKat.

Use Cloud Storage:

I think what you would need to do is back this up through Cloud Storage - iCloud in terms on Apple. Fro there, you can choose where and how to storage it through iCloud. Not so certain that this would sacrifice your goal here, but this is what Google AI has to say on this: accessing Yamaha MDF2 MIDI Data Filer on icloud. Essentially, you would create a folder on your Desktop and the designate that as to where these created files to be saved to, by default. That seems the ultimate way to achieve this: though cloud storage.
