I've already had a good look around for a solution to this and haven't seen an existing thread - yet. I have a MacBook Pro 11,3 Retina Late 2013 15 inch 2.6 GHz i7 running Yosemite 10.10.5. I also have a MacBook Pro 6,2 15-inch Mid 2010 2.66 GHz i7 running Snow Leopard 10.6.8, which I don't really use any more. My older on will connect to ftp's or afp's (I had to upload some work to a company's computer using either an afp or ftp and it's uploading via the afp right now. My current newer MBP won't connect to ftp's or afp's and I'd like to find out why. When I try it just times out using either method. Both have the firewall's turned off. Both are on the same network and accessing the same afp or ftp address. I can upload things to the internet (dropbox, email attachments etc.). Can anyone suggest something I could try to make my newer one work?
