Downloading ObjectTools 5.0 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. The actual developer of this Mac application is Aparajita Fishman. The application lies within System Tools, more precisely File Managers. We recommend checking the downloaded files with any free antivirus.
From the developer:
ObjectTools is a plugin that gives you a full suite of commands for managing an object. An object is a sort of a BLOB, but instead of accessing anonymous items sequentially or by offset, you access each item by name. You can directly access, modify and delete array elements within an object without copying the array into a variable.
