Specs: Mac book air, os x 10.8.5 Since the update at 08/16/16, my friends list got buggy so I decided to do a fresh reinstall, I backed up my steamapps folder, deleted it from applications and library and reinstalled (Note that steam runs on a seperate non-case sensitive partition). But now it's just stuck on this window and won't change. I tried reinstalling like three times and no avail. Any help?
This most likely has to do with using a case-sensitive filesystem on MacOS. Steam is unable to locate the correct resources for the login window, locales and so forth.
Verify that this is the case by opening Disk Utility or execute the following command in your Terminal:
diskutil info / | grep -A2 Personality - File System Personality: Case-sensitive Journaled HFS+ Type (Bundle): hfs Name (User Visible): Mac OS Extended (Case-sensitive, Journaled)
You will need to rename resource files (*.res, *.tga) to lowercase; these are located at:
/Users/$(whoami)/Library/Application\ Support/Steam/Steam.AppBundle/Steam/Contents/MacOS/public /Users/$(whoami)/Library/Application\ Support/Steam/Steam.AppBundle/Steam/Contents/MacOS/steam/cached/ /Users/$(whoami)/Library/Application\ Support/Steam/Steam.AppBundle/Steam/Contents/MacOS/friends /Users/$(whoami)/Library/Application\ Support/Steam/Steam.AppBundle/Steam/Contents/MacOS/graphics /Users/$(whoami)/Library/Application\ Support/Steam/Steam.AppBundle/Steam/Contents/MacOS/servers
Asturaz apparently already brewed up a small script to automate this, located here: http://steamcommunity.com/discussions/forum/2/282992646978253149/#c282992646985999495
