#How to transition from EasySIMBL to SIMBL

( ~ is your home directory )

1. Launch EasySIMBL.app. Turn OFF Use SIMBL checkbox. Quit EasySIMBL.
2. Remove ~/Library/ScriptingAdditions/EasySIMBL.osax if exists.
3. SIMBL directory and EasySIMBL.osax located in ~/Library/Containers/ is not needed. Find from Finder or find command like find ~/Library/Containers -name "*SIMBL*" -ls and remove manually if exists.
4. Restart Mac (just in case).
5. Install SIMBL-0.9.9 (original SIMBL-0.9.9.pkg is not code signed. So open from context menu)
6. Done.

Two-box osx kernel development

This is an officially unsupported two-box setup, suitable for real kernel (and sometimes kext) development.

Target box setup w/ development kernel

Make sure the box has plenty, but not too much, ram, unless you enjoy wasting time doing either virtual or actual paging.
