Hey there,

i decided on studying reverse engineering/cracking because im sort of bored with my Chemistry Studies right now and some additional hobby is probably going to do me some good.

Now i own a core 2 duo Intel Macbook Pro, and im currently looking for good debuggers like Ollydbg and Softice. Unfortunately they are not to be found for OSX and the only free debuggers i was able to find were GDB which is commandline based but theres also a GUI version which ive heard not to be... great.

IDA Pro apparently has an OSX version but i wasnt able to get my hands on a copy of it, besides i doubt most of the releasegroups for OSX apps have a copy of IDA at hands.

Sooo generally what would be highly appreciated is any advice on good debuggers for OSX, aswell as maybe some crackmes (+ tutorials) for OSX specific applictions, as those are not to be found anywhere.

This would be highly appreciated. Or any advice in general.


Peace,
Stoli

u may want 2 take a look, 4 starters, @ otx :


http://trac.macports...el/otx/Portfile

5 name otx
6 version 0.16b_dev
7 categories devel sysutils
8 maintainers eridius@macports.org
9 description otool's bastard son
10 long_description {otx stands for "object tool extended". otx uses otool(object tool) to disassemble a Mach-O executable file, then enhances the disassembled output. Simple enhancements include adding the machine code of each instruction and the offset of each instruction from the beginning of a function. More complicated enhancements include displaying the names and data types of Objective-C methods even if symbols have been stripped, and adding comments that describe member variables, function calls, static data and more.}

Got OTX and GDB now and been working through some PPC crackme tutorials, but the lack of intel based crackmes for OSX is making me sick.... "lack" meaning non-existant
