How to Fix Photoshop & Adobe Apps Crashing in macOS Tahoe 26.2

Symptom: Adobe Photoshop, Premiere, or Illustrator crashes immediately upon launch on macOS Tahoe. Or, you receive a "scratch disk full" error despite having plenty of space.

TL;DR fix

Start with Fix 1: Reset Adobe Permissions (Free). If the issue persists after that, try Fix 2: Purge Adobe Scratch Files (Free). Full Terminal commands and step-by-step instructions are in each section below.


Why this happens

macOS Tahoe 26.x changed how applications access "Protected System Memory." Older versions of the Adobe Creative Cloud suite (and even some newer builds) struggle with these new security permissions, leading to a crash-on-launch or "Permission Denied" errors.

Recommended Troubleshooting Tool

Before proceeding with manual fixes, we recommend using CleanMyMac X. Quickly identify high CPU apps and optimize system memory with one click.


Fix 1: Reset Adobe Permissions (Free)

You need to manually "whitelist" Adobe apps in the new Tahoe security layer.

  1. Open System Settings
  1. Add Adobe Apps
  1. Reset TCC (Advanced)

Fix 2: Purge Adobe Scratch Files (Free)

If Photoshop opens but is sluggish or "Full," you need to clear the hidden temporary files.

  1. Navigate to Temp Folder
  1. Delete Scratch Files

Fix 3: The Automated "Creative" Solution

When you need your professional tools to work *now*.

Adobe apps leave "residue" in deep system folders that manual deletion won't reach. If you've tried reinstalling and it still crashes, you have a corrupted "App Support" folder.

Recommended Tool: CleanMyMac X

- Uninstaller & Reset: Don't just delete the app. Use CleanMyMac X's "Uninstaller" and select Reset instead of Remove. This deletes all preference and cache files without needing to re-download the 2GB application.

- RAM Optimization: Running the "Free Up RAM" tool before launching heavy apps like Premiere ensures the system doesn't "panic" and crash due to Tahoe's new memory management.

Alternative: Adobe Creative Cloud Cleaner Tool

Adobe provides its own deep-cleaning tool for when their installers fail.
