I have a G4 Titanium laptop at home that allows me to "View Full Screen" in Preview. At work, I use an iMac and Preview does not allow me to view full screen. Is there an upgrade that I need? If so, where do I get it?

Thanks.

KL :p

There are two different "full‑screen" behaviors in Preview and they often get mixed up: Preview’s own presentation-style display (for showing images or PDF pages without window chrome) and the operating‑system full‑screen window mode that was added later. That difference explains why the G4 laptop you mention might show an option your iMac does not — the available Preview features depend on the macOS / Preview version installed. See Apple’s Preview documentation and the OS X Lion announcement describing when system-wide full‑screen support arrived. (Preview User Guide) (support.apple.com)

Quick checklist to diagnose and fix the mismatch:

  • Confirm which macOS the iMac is running (Apple menu > About This Mac / System Information) and note the Preview app version shown in Preview’s app menu. If the iMac is on an older OS the newer system full‑screen features won’t be present.
  • If the Mac can run a newer macOS and you want the OS‑level full screen, update via Software Update / System Settings so you get the latest Preview features. Apple documents both checking System Information and updating macOS. (System Information guide, Update macOS). (support.apple.com)

Other practical points not covered in the thread: Preview’s presentation behavior depends on file type and how files are opened (multiple images need to be in the same Preview window to be shown as a collection). If a toolbar or navigation controls are hidden they can be shown from Preview’s View menu. As an alternative on older Macs that can’t be upgraded, Quick Look still provides a fast, full‑size preview and basic slideshow-like browsing for selected files. If upgrading isn’t possible, a third‑party image/PDF viewer can fill the gap. ’s note about Panther, and the comments from and , reflect how different OS/Preview versions expose different UI for "full screen" — checking the macOS/Preview versions above will show which path to follow.

I cannot get a full screen on my computer. Tried everything. Any suggestions?

Stop hijacking threads. If you have a problem, post it in a new thread, and be more descriptive about the problem rather than just "I can't get fullscreen".

You just need to hit the "slideshow" button located in the toolbar above the image. Apple can be funny that way... not entirely obvious that is.
