Block Adobe Creative Cloud from Accessing the Internet on Mac
Stop Telemetry, Updates & Background Uploads
Key Takeaways
Adobe Creative Cloud runs multiple background processes that phone home constantly
Hosts file blocks break every time Adobe rotates their domains
Per-app blocking stops all Adobe network activity without fragile domain lists
What Adobe Creative Cloud Does in the Background
Open Activity Monitor after installing Creative Cloud and you'll see multiple Adobe processes running, even when you're not using any Adobe app.
These background processes handle:
- •
License validation checks
- •
Usage telemetry and analytics
- •
Cloud storage syncing (Creative Cloud Files)
- •
Font syncing (Adobe Fonts)
- •
Update checking and downloading
Why People Want to Block Adobe
- •
Bandwidth — large updates download without warning
- •
Privacy — telemetry reports usage patterns back to Adobe
- •
Performance — background processes consume CPU and memory
- •
Control — updates can change features or remove tools you rely on
- •
Metered connections — unwanted sync burns through data caps
Method 1: Hosts File Blocking (Fragile)
The most common advice online is to edit /etc/hosts and block Adobe's known domains. There are popular GitHub repos maintaining lists of Adobe telemetry domains.
Adobe uses many domains and subdomains that change over time. Hosts file blocks that work today may stop working as Adobe updates their infrastructure.
Method 2: Little Snitch or LuLu (Noisy)
Traditional outbound firewalls like Little Snitch and LuLu can block Adobe's connections, but you'll need to handle each connection individually. Adobe apps make connections to many different domains and services.
Method 3: Per-App Blocking with SplitTunnel (Recommended)
Block Adobe Creative Cloud at the application level. No domain lists, no per-connection prompts.
Install SplitTunnel on your Mac
Set Adobe Creative Cloud to "Block"
All Adobe background network activity stops immediately
Photoshop, Illustrator, and other Adobe apps continue to work offline for local file editing. They just can't reach Adobe's servers.
What Still Works When Adobe Is Blocked
- •
Opening and editing local files (PSD, AI, INDD)
- •
Exporting and saving locally
- •
Using installed fonts
- •
All offline functionality
What Stops Working
- •
Adobe Fonts syncing (already-installed fonts still work)
- •
Creative Cloud file syncing
- •
License re-validation (existing license works for the offline grace period)
- •
Adobe Stock browsing
- •
Collaboration features
Recommended Setup
Keep Adobe blocked by default. When you need to sync files or check for a specific update, unblock it temporarily from the menu bar, do what you need, then block it again.
