Downloading PullRequestMenu 1.1 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. This free Mac app was originally developed by Ognid. The software relates to Developer Tools.
From the developer:
PullRequestMenu is a simple menu bar app that provides quick access to your active GitHub pull requests. Optionally, the program will display a desktop notification when you get a new request. The application works with public GitHub and with GitHub Enterprise installations.
You may want to check out more software for Mac, such as Boks, Navicat for Oracle or GoodPage, which might be similar to PullRequestMenu.
