Please beware that you will need a new Activation Key, after upgrading to Just In Mac v5.0. The latest version (v5.1) does not require a new key (v5.0 and v5.1 are using the same activation code).
Download & Installation
Download Just In Mac v51 from the ToolsOnAir Support System (free account required). Open the disk image and copy & paste the Just In Engine and the Just Control application to your Applications folder.
Upgrade from an older version of Just In Mac
When you update your existing Just In Mac v4.0 or v5.0 installation, then simply copy & paste the new version into your Application folder. All existing settings will be taken over and you can start using the new Just In Mac version without any further action (apart of the new Activation Key, only when upgrading from v4.0).
If you are updating from an older version of Just In Mac (v3.5 or older), please contact us and/or create a ticket in our Support System, so that we can help you with the installation process.
