CloneKeys 0.5 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. CloneKeys-0.5.beta.dmg is the frequent file name to indicate the CloneKeys installer.
The most popular version among the program users is 0.5. According to the results of the Google Safe Browsing check, the developer's site is safe. Despite this, we recommend checking the downloaded files with any free antivirus software. This free Mac app was originally produced by R Jenkins.
From the developer:
CloneKeys duplicates (clones) incoming keystrokes and sends them to the applications as setup in the main CloneKeys configuration window.
This is mostly useful for multi-boxing in games. (Open up multiple copies of World of Warcraft and use CloneKeys to send the same keystrokes to multiple windows simultaneously.)
