Interface Inspector简介
Interface Inspector是用于查看mac os app界面布局的利器，类似于iOS的Reveal。
破解过程
下载下来打开后，出现一个License窗口：
License
hopper的Strings表里面搜索 License ，发现有这么一个方法：
-[SMLicenseManager isLicensed]
Modify -> Assemble Instruction...(option+a)，修改返回值为YES：
-[SMLicenseManager isLicensed]:
000000010010fe70 mov rax, 0x1
000000010010fe77 ret
File -> Produce New Executable...command+shift+e，选择Remove Signature，替换原可执行文件。
然后打开，弹出了：
Signature
它验证签名了，我们Strings表里面搜索 Sign ，发现 codeSignState字符串
x查看引用，在applicationWillFinishLaunching中调用了这个方法：
void -[SMAppDelegate applicationWillFinishLaunching:](void * self, void * _cmd, void * arg2) {
rdx = arg2;
rbx = self;
var_30 = *___stack_chk_guard;
rax = [NSBundle mainBundle];
rax = [rax retain];
var_128 = rax;
if ([rax codeSignState] != 0x2) goto loc_100024851;
......
loc_100024851:
r14 = [[NSAlert alloc] init];
var_F8 = r14;
r13 = [[NSBundle mainBundle] retain];
rbx = [[r13 localizedStringForKey:@"Signature of the Interface Inspector is broken" value:@"" table:0x0] retain];
需要把codeSignState的值修改为0x2。
在SMFoundation.framework找到这个方法，直接修改：
-[NSBundle codeSignState]:
000000000003b298 mov rax, 0x2
000000000003b29f ret
替换SMFoundation后再次运行，成功了！
