Thanks for everybody who helped me with my OSX wallet.

It took me a long time to find what was the issue. if anybody is in the same situation, here is what i did:

You have to create a 808.conf file and put it in a hidden folder under user/(yourname)/library(hidden)/application support/808

---------------
show all files

---------------


Now the important part, text edit doesn't let you create a .conf directly.

Go to preferences:

under format: check plain text
under open and save: uncheck add .txt extension for plain text files
then RESTART the application

Open textedit and copy the nodes from this link: https://novaexchange.com/addnodes/808/
and save it as 808.conf in the right location.
The wallet should then synchronise (it took me a long day to synchronise the first time - you should see a progress bar if it does)


Hope it will help other mac users
