Re: st: Stata 13.1

I am having trouble installing this update. I am using Stata SE 13 for Mac in Mac OS X v. 10.9, i.e. Mavericks. The message I get when I type update all, and after I confirm that it is OK to close Stata is:
cannot write in directory /Applications/Stata/.tmp
The fact is that the directory doesn’t exist. I have tried creating it, but the system will not let me because it says that directory names that start with a . are reserved for system directories and asks me to enter a different name.
Is there any way around this?
