Adobe Photoshop CS4 Extended for Mac
Mac Photo & DesignAdobe Photoshop CS4 Extended for Mac is the top-tier 2008 edition of Photoshop, released as part of Creative Suite 4. Beyond regular CS4's photo editing and compositing tools, the Extended edition added 3D editing, motion graphics and measurement tools aimed at technical and scientific imaging.
This software is long discontinued and this page is for reference only. Adobe ended the CS era when it moved Photoshop to Creative Cloud subscriptions in 2013, CS4 activation servers and support are gone, and the program predates modern macOS by many generations, so it will not install or run reliably on a current Mac. There is no official download and no legitimate way to buy CS4 Extended today — the supported option is current Photoshop from Adobe.
Key Features
- Complete CS4 photo editing core: layers, masks, adjustment layers and retouching tools
- Extended-only 3D editing: paint on 3D models, wrap 2D images onto 3D shapes and animate them
- Motion graphics tools for editing video frames and creating simple animations
- Measurement, counting and analysis tools for technical and scientific images
- Content-Aware Scaling and the Adjustments and Masks panels introduced in the CS4 generation
How to Download
- There is no official download to use: Adobe no longer sells, distributes or activates Photoshop CS4 Extended.
- For a working Photoshop on a modern Mac, install the current version from Adobe instead — it opens the same PSD files this edition created.
Is Adobe Photoshop CS4 Extended free?
No. It was expensive paid software in 2008 and was never released as freeware. Copies offered as free downloads today are pirated and often carry malware.
Will CS4 Extended run on my current Mac?
Almost certainly not. It is PowerPC-era transitional software built for Mac OS X versions of its time and depends on activation systems Adobe has retired. Use current Photoshop instead.
