If you can’t get past the install updates prompts in Titanium Studio, it could be due to authentication issues with the underlying operating system.
For example, I have NOPASSWD: ALL set in my /etc/sudoers file on my mac (naughty, I know) however, this seems to really stuff up the automatic installer in Titanium Studio. I would click on the install button and get nothing – no response from the UI at all.
The only feedback in the system log was this:
praj : TTY=unknown ; PWD=/Applications/Titanium Studio/TitaniumStudio.app/Contents/MacOS; USER=root ; COMMAND=/bin/echo SUCCESS
Once I took out that line in /etc/sudoers (and let it prompt me for a password when using sudo), I received the login dialog box and could continue with the install. Frustrating, but I hope this saves someone else a few hours of troubleshooting.
