Recently I installed Mountain Lion (I had Snow Leopard), I used to share files with a PC enabling the file sharing and use Filezilla in the PC to download and upload files.
Now with Mountain Lion for some reason I can't connect to the Mac computer. Nothing changed; I'm using the same credentials. This is exactly what I did: http://www.dummies.com/how-to/content/how-to-set-up-file-sharing-from-mountain-lion.html
Is there some kind of new security policy or something similar in Mountain Lion?
