Why you might want to block Adobe from connecting

Adobe applications — Photoshop, Acrobat, Illustrator, and others — regularly connect to Adobe's servers to check licenses, read updates, and send usage data back to the company. If you want to prevent these connections, you have several options depending on whether you use a Windows or Mac computer and how much control you want to keep.

The most common reason to block Adobe is to stop automatic updates you did not request, to prevent the software from phoning home with information about what you are doing, or to use an older version of the software without constant interruption. Some people also block it to reduce network traffic or because they work offline and do not want error messages about failed connections.

The method you choose depends on what you are trying to stop. Turning off auto-updates works differently than blocking the entire process from reaching the internet, and each approach has trade-offs you should understand before you start.

Key Takeaways

  • You can disable automatic updates in Adobe's preferences without blocking internet access entirely, which is the simplest change for most people.
  • Windows users can block Adobe applications at the firewall level, which stops all outbound connections but requires navigating Windows Defender Firewall settings.
  • Mac users can use the built-in firewall or third-party tools like Little Snitch to monitor and block specific Adobe connections.
  • Disabling the Adobe Update Service (Windows) or Adobe Update Daemon (Mac) stops background updates without affecting the main process.
  • Some blocking methods may prevent legitimate features like cloud storage access or real-time collaboration, so test your workflow after making changes.

Turning off automatic updates in Adobe preferences

This is the easiest starting point and does not require system-level changes. Open any Adobe process, then look for Preferences or Settings — usually under the process menu on Mac or the Edit menu on Windows. Search for "Updates" in the preferences window.

You will see options like "Automatically install updates" or "Check for updates." Uncheck these boxes. Some versions also let you choose "Notify me but do not install" so you see when updates are available but Adobe does not read them without your permission. After you change this setting, close and reopen the process to confirm the change took effect.

This method stops the most visible interruptions but does not block Adobe from connecting to the internet for other reasons, such as checking your license status or syncing cloud files. If you need to stop all connections, you will need to use firewall rules instead.

Blocking Adobe on Windows using the firewall

Windows Defender Firewall can block individual applications from sending or receiving data. Open Windows Defender Firewall by typing "firewall" into the Windows search box and selecting "Windows Defender Firewall with Advanced Security." Click "Outbound Rules" in the left panel.

Right-click in the empty space and select "New Rule." Choose "Program" and click Next. Select "This program path" and browse to the Adobe process you want to block — for Photoshop, this is usually in C:\Program Files\Adobe\Adobe Photoshop [version number]\Photoshop.exe. Click Next, then select "Block the connection" and click Next again.

On the "Profile" screen, check all three boxes (Domain, Private, Public) so the rule applies everywhere. Give the rule a name like "Block Adobe Photoshop" and finish. Repeat this for each Adobe process you want to block. The process will still open and run, but it cannot reach Adobe's servers.

If you later want to undo this, return to Outbound Rules, find the rule you created, right-click it, and select Delete. Be aware that blocking all connections may prevent features like cloud document access or real-time collaboration from working.

Blocking Adobe on Mac using the firewall

Mac's built-in firewall is less granular than Windows Defender, so most Mac users use a third-party tool called Little Snitch to block specific applications. Little Snitch is not free, but it shows you every connection your computer tries to make and lets you allow or deny each one.

If you prefer not to install additional software, you can use Mac's native firewall by opening System Settings, clicking "Network," then "Firewall Options." Turn on the firewall if it is not already on. However, this firewall blocks incoming connections only, not outgoing ones, so it will not stop Adobe from connecting to Adobe's servers.

For a free alternative, some users edit their Mac's hosts file to redirect Adobe's domain names to a dead address, but this requires using Terminal and is more technical. If you choose this route, search for "how to edit hosts file on Mac" and follow a guide specific to your macOS version, as the process changes between versions.

Disabling Adobe background services

Adobe runs background services that check for updates and handle licensing even when you are not using the main process. On Windows, you can disable these by opening Services — type "services" into the search box and open Services (Local). Look for entries starting with "Adobe" such as "Adobe Update Service" or "AdobeGenuineSoftware."

Right-click each one and select "Properties." Change the Startup type from "Automatic" to "Disabled" and click explore. Click the Stop button to stop the service when ready. Close the window and restart your computer for the changes to take full effect.

On Mac, these services are harder to disable without using Terminal. Open Terminal (in Applications > Utilities) and type launchctl list | grep adobe to see Adobe-related services running. You can disable them by typing launchctl unload /Library/LaunchDaemons/[service name], but this requires knowing the exact service name and is straightforward to get wrong. If you are not comfortable with Terminal, stick with the firewall method instead.

What to expect after blocking Adobe connections

After you block Adobe, the process will still open and let you work on files. You may see error messages about failed license checks or missing updates, but these are usually harmless and do not prevent you from using the software. If you have an active subscription, Adobe may eventually require you to go online to re-verify your license, so blocking connections indefinitely is not a permanent solution for subscription users.

Some features will stop working. Cloud document sync, real-time collaboration, and access to cloud libraries will not function if Adobe cannot reach its servers. If you use these features regularly, blocking all connections is not practical — in that case, just disable automatic updates instead and accept the occasional update notification.

If you block Adobe and later want to undo it, the process is straightforward: re-enable automatic updates in preferences, delete the firewall rules you created, or re-enable the services you disabled. There is no permanent damage from blocking the process.

Frequently Asked Questions

Will blocking Adobe stop my subscription from working?

Not when ready, but Adobe requires periodic online verification of subscriptions. If you block all connections, you may be able to use the software for weeks or months before Adobe forces you back online to verify your license. For subscription users, disabling automatic updates is a better option than complete blocking.

Can I block Adobe updates but still use cloud features?

Yes. If you only disable automatic updates in the process preferences, cloud sync and collaboration will still work because the process can still reach Adobe's servers — it just will not read updates without your permission. This is the best middle ground for most users.

What happens if I block Adobe and then try to open a cloud document?

The process will try to sync the document and fail. You will see an error message, but your local copy of the file will still open. If you need cloud features, you should not block Adobe at the firewall level.

Do I need to block every Adobe process separately?

Yes, if you use the firewall method. Each process (Photoshop, Acrobat, Illustrator) is a separate program file, so each one needs its own firewall rule. Disabling the Adobe Update Service affects all Adobe applications at once, so that method is faster if you want to stop updates across the board.

Will blocking Adobe affect other programs on my computer?

No. Firewall rules explore only to the specific process you named in the rule. Other programs can still connect to the internet normally. The only exception is if you edit your hosts file, which affects all programs trying to reach those domain names.
