On Windows using WebDAV (Windows Explorer) vaults could not be unlocked
Yay. As of v1.6.5, the developer is providing an ARM version of Cryptomator, making it compatible with all M1 processors. It still has an option requiring abandoned MacFUSE. But you can work around it and use WebDAV instead. The documentation of their $10 iOS app is essentially nonexistent. But they're supposedly working on it, despite the app being 4 years old. (o_0) ...Time will tell. I upped its stars to three.
NOT M1 Mac ready. It runs, but it wants to use MacFUSE, which is inert on M1 Macs. AND MacFUSE has been *abandoned* by Google in any case! As such, Cryptomator is significantly useless on M1 Macs. Unless they have plans to rewrite it for ARM, you might as well toss it. - - It should still work fine on Intel Macs.
This is a great app for some added insurance when using cloud services. I was encrypting files individually which can be time consuming. With Cryptomator I just add the file to the image on the cloud from my desktop, a simple drag and drop. Great app, highly recommended if you are at all concerned about security and who shouldn't be?
