Class dump installation method

Rootless, a new feature added in Mac system 10.11, limits the permission of root user (/ usr/bin, no change allowed). Change the environment variable to use class dump.

Class dump download address

http://stevenygard.com/projects/class-dump/

1. First, create a new bin directory under the current user. In the terminal

mkdir ~/bin

2. Open the dmg of the downloaded class dump, copy all the files in it to the bin directory created, and give it executable permissions

chmod +x ~/bin/class-dump

3. Open the Bash? Profile file to configure the environment variable and add: export PATH=HOME/bin/:PATH on the last line

vim ~/.bash_profile

4. After adding, execute

source ~/.bash_profile

5. Test success
