I have a 2012 Macbook Pro working perfectly on MAC OS Catalina and it is not upgradeable to anything later.
However, in a world where we're bombarded with "Green" issues, being forced to upgrade a perfectly usable device just to access the latest, albeit not earth-shattering, sync app is frankly despicable.
In addition, many will never upgrade to a later OS until much later than it's release, as to be on the latest version is a risk in itself, especially to the security conscious.
Whichever way you slice it, this is very poor from Proton.
P.S. Google Drive works flawlessly on this machine
