since my update to yosemity my sidebar is in dutch but my entire mac is english. total finder is working (after i reinstalled it for the original version i had was incompatible) but i find this sidebar in the wrong language disturbing.
what do i need to do to get the side bar in english?
I have the same issue with germansidebar on a english mac.
Have you found a solution?
If some of your Sidebar folder has different Language, You can set as OS X language by simply add .localized file in the folder.
For instant, you have different language folder such pictures in Dutch, you can add this file via Terminal
this command line make .localized file into Pictures folder and that make your folder name changes to your language.
Hope you can enjoy mac more!!
