Sharing the Same DAW Project Files Between Two Macs; Cloud Storage?

We struggle with this workflow- My assistant and I work on projects together using Kontakt 7 in Logic. We own all the same NI products, but when we open the project on our respective systems, NI cannot resolve the location of the instruments without being told where they reside on the system in use. Mostly this will resolve after one of the "missing" instruments is located. And it seems that user-created Kontakt instruments are more likely to show up missing than factory Kontakt libraries. From what I have read this is actually expected behavior, but on large projects with many many instances of Kontakt, it can be a real wrench in the works.

Any suggestions for how to make this fly would be appreciated. (We are indifferent cities, BTW, so a shared hard drive is not an option. And syncing our systems is not practical as we both work on other projects outside our collab.)

Yeah, I also see this issue with things like Battery!

If hte exact path to the factory content is not the same on all systems it complains about missing content. When I open a project from one of my machines on another where the path is different it only seems to look in the location of the path on the first machine, pops up saying the content at that location cannot be found.

If I manually select the factory location on the new machine and scan, it is resolved but this is a PITA and kind of why I don't use much NI stuff these days, especially Battery, in favor of other VSTs. I (and others) have raised this many times over the years in various avenues but I kind of give up raising issues these days and just either work around or discontinue using what doesnt work for me.

Yeah I’ve done all that but still have issues. I setup heaps of mapped racks for Ableton years ago but after a new build the drive/path of my factory content has changed and although the new factory content opens just fine, everything that references the older path throws a damn error

I use iCloud for cloudsyncing Ableton projects between a mac studio and MBP since two years back. Works great for my needs - the Ableton user library is synced between machines the same way, without lifting a finger. It helps if youre organised with installing new plugin versions simultaneously on both machines of course. This also means that every time Timemachine runs on one of the machines, the Ableton library and ongoing projects are backed up. Dropbox is - in my opinion - the best, fastest and most effortless cloud sync option - iCloud just happens to be cheaper. Worth a try?

Lots of great comments here and definitely something that should for for OP.

One other thing I'll mention, if you're looking for a more all-in-one solution to a few of these types of challenges is Tonic Audio (https://tonicaudio.com). It has cloud storage much like Dropbox/Google Drive, which is cool, but also has some really nice features for managing file versioning--which I feel like always gets left out of discussions. Add the ability to leave feedback on particular versions of files, and it gets really helpful, especially when at the mix stage.

It also has a ton of other features, but for this particular need, it works really well.

And full-disclosure, while I work at Tonic Audio, I mention it here because use it all the time for just this use-case, and have quickly passed their 5GB free plan, as I participate in a lot of remixes and mixing for other artists.
