阅读更多关于 How to put a tkinter window on top of the others?

问题 I'm using Python 2 with Tkinter and PyObjC , and then I'm using py2app . The program is working fine, but the window starts as hidden whenever I open the program, so it doesn't appear until I click on the icon on the dock to bring it up. Is there any way to control this, make the window to be on top of other windows that were open when the application is starting? Just to clarify, it doesn't have to be on the top for the whole time the application is running. I just need it to be on top of

问题 I recently upgraded to 10.7.3, and when I try to debug my iOS project in the simulator for the first time after logging in, I'm prompted with the following two alerts: My user is an admin user. I never saw these alerts before. How do I get them to stop? EDIT I've verified that I'm a member of the _developer group using id -a . 回答1: There's a much simpler solution for this. Try running the following command: sudo /usr/sbin/DevToolsSecurity --enable 回答2: enable develoer mode: In Terminal run

How to fix Terminal not loading ~/.bashrc on OS X Lion [closed]

阅读更多关于 How to fix Terminal not loading ~/.bashrc on OS X Lion [closed]

问题 Whenever I open a new tab in Terminal using Cmd + T , it opens bash in the same directory, as the previous tab. This works fine when I'm in the ~ directory, but if I'm anywhere else, I get an error loading .bashrc Last login: Sat Oct 15 21:10:00 on ttys002 -bash: .bashrc: No such file or directory Jakub-Arnolds-MacBook-Pro:projects darth$ It looks like .bashrc is loaded via relative and not absolute path, because if I do source ~/.bashrc , everything works smoothly. I think this is a OS X

How to run 32-bit Java on Mac OSX 10.7 Lion

阅读更多关于 How to run 32-bit Java on Mac OSX 10.7 Lion

问题 From my experience with Windows 7 (64-bit) and Java, a 32-bit JRE uses less memory and runs significantly faster than a 64-bit JRE (provided you don't need or benefit from having a lot of memory). I imagine the same thing is true for Mac OSX (and other platforms) as well. I am currently running OSX Lion (v10.7), and I have installed the standard Java app. Under Java Preferences, I see "Java SE 6" from "Apple Inc." for both CPU-types "32-bit" and "64-bit" version "1.6.0_26-b03-383". I have

What is the “Illegal Instruction: 4” error and why does “-mmacosx-version-min=10.x” fix it?

阅读更多关于 What is the “Illegal Instruction: 4” error and why does “-mmacosx-version-min=10.x” fix it?

I get Illegal Instruction: 4 errors with binaries compiled with GCC 4.7.2 under Mac OS X 10.8.2 ("Mountain Lion"), when those binaries are run under Mac OS X 10.7.x ("Lion") and earlier versions. The binaries work properly under Mac OS X 10.8.x. I added -mmacosx-version-min=10.5 to my compile flags and this seems to help resolve the issue for 10.5.x, 10.6.x and 10.7.x clients, whatever that issue is. Which gets to my question(s): What is the Illegal Instruction: 4 error? Why does -mmacosx-version-min=10.x fix this specific error on 10.x and greater clients? I'd like to apply this fix to my

问题 I used to be able to use three finger scroll-up to switch between source/header. Since upgrading to Lion, I it just does a regular scroll. Is there any way to get that feature back? Aka, it doesn\'t jump to counterpart when I scroll up / down like it used to. Update Apple fixed the issue in Xcode 4.2. So, upgrade your versions. 回答1: This is the correct and best answer. It works. It is posted by "@Buyin" above. Another individual commented that it doesn't work. He is wrong. It works, I've

Writing a privileged helper tool with SMJobBless()

阅读更多关于 Writing a privileged helper tool with SMJobBless()

问题 Even though the API has been open since Mac OS X Leopard, there\'s surprisingly, and unfortunately, very little documentation on how to correctly use SMJobBless() for creating privileged helper tools. There are a lot of gotchas, even when copying code directly from Apple\'s sample project. Luckily, I\'ve found my way around this, and have gotten the basis for my helper tool working. However, it would seem that SMJobBless() only blesses the tool and copies it over, but doesn\'t run it. I\'ve
