问题 I'm getting a common Mac OSX error for Homebrew installations of Postgres, No such file or directory Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"? This is apparently due to there being multiple installs on the system. However, the usual steps are not resolving things. I can successfully start Postgres and running: ps auxw | grep post returns .. euanmillar 847 0.0 0.0 2432768 588 s000 R+ 11:19am 0:00.00 grep postgres euanmillar 845 0.0 0.0

问题 I had Xcode 4.1 preview 5 working fine but decided to upgrade to the final xcode 4.1 thru the App store. I uninstalled Xcode first... sudo /Developer/Library/uninstall-devtools –mode=all Then installed Xcode thru the app store and rebooted.

问题 I'm making an app which lives in status bar. When status item is clicked, NSPopover pops up. It looks like this: Here's the problem: I want it to be "transient", that is if I click anywhere outside of the popover, it will close. And while NSPopoverBehaviorTransient works fine when popover is in a window, it doesn't work when it's in status bar. How can I implement such behavior myself? 回答1: It turned out to be easy: - (IBAction)openPopover:(id)sender { // (open popover) if

问题 I've written a program in the Mac App store which displays some graphics. Occasionally it updates these off the internet. As with most folks, I'm having to Sandbox my app now. Almost everything is working, but when updating it saves a file in my app's own bundle and fails with 'sandboxd: deny file-write-create' I just use fopen(..., "wb") The path passed into fopen is: /Users/MyUser/Library/Developer/Xcode/DerivedData/MyApp-czuwveatgjffaggwqjdqpobjqqop/Build/Products/Debug/My.app/Contents

I need to turn off all auto-correct off for all apps, not just in my own NSTextField . Is there any way for me to check/set the global/system auto-correct feature to OFF ? Or am I stuck basically providing a guided tutorial for how to turn it off? Solution must be legal for the Mac App Store. 回答1: Is this in an

问题 I need to do it for a C++ program that needs a lot of stack. I use g++ (included in OS X Lion) to compile it. How could I increase it for my program? 回答1: From http://developer.apple.com/library/mac/#qa/qa1419/_index.html Using gcc, pass link flags through to ld with -Wl: gcc -Wl,-stack_size -Wl,1000000 foo.c 回答2: You can use getrlimit / setrlimit - this works on Linux, Mac OS X, and other POSIX-ish operating systems, e.g. #include <sys/resource.h> int main (int argc, char **argv) { const
