Hi there,
I am yet another disillusioned BTSync user, looking for an alternative. SyncThing looks very promising and I am going to give it a try. My main computer is an ancient MacBook Pro with an Intel Core Duo running Snow Leopard (Mac OS X 10.6). Unfortunately, this dinosaur has a 32-bit CPU, so the official binary at https://github.com/syncthing/syncthing/releases/download/v0.10.26/syncthing-macosx-amd64-v0.10.26.tar.gz won’t work for me. Thank goodness SyncThing is open source and I, despite my noob-ness, managed to build my own SyncThing binary, which seems to work, although I have not thoroughly tested it yet. I figured that there’s possibly more people out there who may be interested in a 32-bit Mac version of SyncThing so I put it online at (link deleted by topic starter because there are now official 32 bit Mac builds).
If, somehow, this post is undesirable in any way, please let me know.
