«Easy hack» #2: fake geolocating for Tweetbot (OS X).

0readme.markdown

A simple way to specify fake longitude and/or latitude for your tweets in Tweetbot

1. Download llocy.dylib from here or compile it yourself from sources (see the llocy.mm below).

2. Move this llocy.dylib to any place on your disk. I've placed in ~/Library/Application Support/Tweetbot/llocy.dylib so I'm going to use this path in examples below.

3. Close Tweetbot if you haven't done it yet.

4. Open Terminal.app (/Application/Utilities/Terminal.app) and enter (or just copy-paste) this command (without $):

   $ DYLD_INSERT_LIBRARIES="~/Library/Application Support/Tweetbot/llocy.dylib" open -a Tweetbot --args 56.885752 -109.294739  
   

   There you must change the path for llocy.dylib to your own, then replace 56.885752 and -109.294739 to your own latitude and longitude respectively.

5. Done! Try to compose a new tweet now (^^,)
