working with a Mac with SVN can be fastidious especially when you have dozen of .DS_Store ..
So you have to look for the subversion config file on the server at the section global-ignores and add this pattern :
global-ignores = *.o *.lo *.la #*# .*.rej *.rej .*~ *~ .#* .DS_Store .AppleDouble ._*
Or if you don’t have enough permission to do this use the svn propedit svn:ignore command
svn propedit svn:ignore files
files is the directory where we want to ignore file, you will be prompt with the default editor to add the pattern of files .. and there it is !
