+Tool designed mainly to solve old problem with unloading native plugins without reopening Unity editor; with vary little changes to code base and low overhead. It enables to replace plugin files between game executions or even while playing.  
 Doing so involves mocking original native method calls with these made to manually loaded libraries by P/Invokes. Although works in builded game, it's intended to use in edtior.

 #### __Options__
 These options are editable via `DllManipulator` script.
-  * __DLL path pattern__ - Path at which mocked plugin files are located. Default is *Assets/Plugins/\__NameOfPlugin[.dll|.so]*. Can be the same as path that Unity uses for plugins.
+  * __DLL path pattern__ - Path at which mocked plugin files are located. Default is *Assets/Plugins/\__NameOfPlugin[.dll|.so|.dylib]*. Can be the same as path that Unity uses for plugins.
   * __DLL loading mode__ - Specifies how DLLs and functions will be loaded.
     + _Lazy_ - All DLLs and functions are loaded as they're first called. This allows them to be easily unloaded and loaded within game execution.
     + _Preloaded_ - Slight preformance benefit over _Lazy_ mode. All DLLs and functions are loaded at startup. Calls to unloaded DLLs lead to crash, so mid-execution it's safest to manipulate DLLs if game is paused.
-  * __[Linux only] dlopen flags__ - Flags used in dlopen() P/Invoke on Linux systems. Has minor meaning unless library is large.
+  * __dlopen flags [Linux and Mac only]__ - Flags used in dlopen() P/Invoke on Linux and OSX systems. Has minor meaning unless library is large.
   * __Thread safe__ - When true, ensures synchronization required for native calls from any other than Unity main thread. Overhead might be few times higher, with uncontended locks. Available only in Preloaded mode.
   * __Mock all native functions__ - If true, all native functions in current assembly will be mocked.
   * __Mock native calls in all types__ - If true, calls of native funcions in all methods in current assembly will be mocked. This however can cause significant preformance issues at startup in big code base.
