Originally, I wanted to use Casper Imaging from the Recovery partition. So this post is based off of this article and this feature request on JAMF Nation. At the end, I realized I probably wouldn’t be able to add this app to the Recovery HD until JAMF updates it to 64-bit. However, this process seems to work for other 64-bit apps. The example I use in this walkthrough is Calculator.app. Continue reading “OS X Recovery Partition: Customizing With Different Apps”

Automator seems to be one of those unknown or ignored Apple-made apps. But it is very powerful and can save you a lot of time. It has also been part of OS X for a long time.
To save time by automatically scaling down images (while keeping the original file) to a pre-set size as opposed to manually editing each one.
Requirements For This Walkthrough
- Mac with OS X
- Large image files
Knowledge, Skills, and Abilities
- Ability to navigate throughout a computer OS
- Knowledge of basic computer terminology
Create the Automator Workflow
You can also download a a pre-built workflow.
- Create a folder for the scaled-down images to go
- Open /Applications/Automator
- Create a workflow similar to the following: (editing the folder and size fields)
- Click File > Save
- Save as something like Reduce to 800×600
Use The New Contextual Service
- Right-click a large image file
- Click Reduce to 800×600
- Watch the magic happen
The scaled-down image will now be revealed in the folder you designated. The original remains in-tact. This operation can also be completed on many files at once. In this example, the picture was 1.8MB and was reduced to 144K.
