We just started using AWS workdocs, which has clients for Mac and Windows (plus iOS and Android iirc). You can either use it as a network drive (Windows only and not fully baked yet) or as a synched folder. There’s also a web interface where you can see the different versions, comment on a file, and which has a decent integration with Office (Workdocs Companion): the file opens in Office, you save your changes and it gets updated remotely. Honestly it’s not great (esp. the UIs which definitely need improvement) but it seems much less erratic than OneDrive. Plus they have frequent updates and they seem to read the questions on the support forum so I’m cautiously hopeful it’ll improve over time. However the best document sharing experience I had was with Jive. It’s what Sharepoint should have been. You get a nice, powerful intranet and a great plugin for Office which makes editing a shared, online file as easy and seamless as a local one. Unfortunately they don’t have a SaaS model (last time I checked) so you have to buy the software and set up and manage the infra yourself.
