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

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 changed the preferred order to put the 32-bit version on top of the 64-bit version, hoping that this would

numpy and scipy for preinstalled python 2.6.7 on mac OS Lion

问题 Is there anyway to install numpy and scipy on python 2.6.7 that comes with Mac OS Lion? I am aware that Lion has Python 2.7 as well. But I need to stick with Python 2.6 cause I am using a module that does not work on Python 2.7. 回答1: Lion comes with an easy_install for each of its Python implementations: /usr/bin/easy_install-2.7 for /usr/bin/python2.7 , and likewise for 2.6 and 2.5. However, scipy requires a Fortran compiler, and Lion doesn't come with one of those. It also looks like you

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 . There's a much simpler solution for this. Try running the following command: sudo /usr/sbin/DevToolsSecurity --enable enable develoer mode: In Terminal run this: DevToolsSecurity -enable Per Zev Eisenberg's answer, reinstalling Xcode 4.2.1 worked. However, it might be

Change selection color on view-based NSTableView

阅读更多关于 Change selection color on view-based NSTableView

问题 Standard highlighting color in OS X applications is blue. Is it possible to change it to another color, e.g. gray? Note that I am using the new view-based NSTableView available starting from OS X 10.7. 回答1: Since you're using the view based NSTableView, you can subclass NSTableRowView, feed it to the table delegate method - (NSTableRowView *)tableView:(NSTableView *)tableView rowViewForRow:(NSInteger)row; , then customize your selection in the row view class. Here's an example: - (void

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]

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 Lion related problem, because before the upgrade from Snow Leopard, I didn't have the same issue. But that
