Burp Suite requires discrete GPU on macOS

Geoff | Last updated: Jun 08, 2017 07:11AM UTC

When running Burp Suite on a macOS machine with a discrete GPU the GPU is activated which reduces the battery life of the device. Does Burp Suite specifically require access to the GPU? I suspect this is most likely related to Java rather than Burp Suite itself as there is a bug report for it https://bugs.openjdk.java.net/browse/JDK-8041900 [main report] https://bugs.openjdk.java.net/browse/JDK-8149265 [apparent resolution] https://bugs.openjdk.java.net/browse/JDK-8132759 [apparent resolution] though I can't see anything in the release notes indicating whether this has actually been merged into a released version of the JRE. Burp Suite: v1.17.23 JRE: 1.8.0_112

Thanks for the report. Burp Suite works fine on an integrated GPU. We don't have a MacBook Pro with discrete GPU handy. To help debug this, could you try: 1) Download and install the Burp Suite MacOS X installer 2) Edit /Applications/Burp Suite Professional.app/Contents/Info.plist and add: <key>NSSupportsAutomaticGraphicsSwitching</key> <true/> Let us know if this resolves the issue and we will see about updating the installer.

Same as initial report. mbp 2018 mojave 10.14.4 (radeon pro 555x) -> burp uses discrete gpu. The provided workaround does not work.

We think this is probably a Java issue. Are you using any other Java applications on this system? Are you encountering the same behaviour?

I notice the same behavior, not sure NSSupportsAutomaticGraphicsSwitching is enough as it seems that you should also indicate support for the offline renderers via the pixel format attribute (https://developer.apple.com/library/archive/technotes/tn2229/_index.html).

Hi Manuel. Can you tell us what version of Java and Burp Suite you are running, and on which OS?

Burp User | Last updated: Jan 06, 2020 02:40PM UTC

Hi Hannah, i'm running BurpSuitePro 2.1.07 installed with the macOS installer, so it's the bundled OpenJDK12, here is my diags output: https://pastebin.com/V8HTeT80

It appears that offline render support is optional. Did you try editing your Info.plist as suggested above? Are you still experiencing issues after attempting that workaround? Have you tried adding offline render support in your Info.plist? Did that make a difference if the suggested workaround did not?

hello. <key>NSSupportsAutomaticGraphicsSwitching</key> <true/> helped me with the same problem in Burp Suite Community Edition Can you add this parameter in the new version?

@s00d Can you confirm that you are using Java 9 or above when launching Burp? The original JDK bugs Geoff referenced appear to have been fixed in Java 9.

Just an update - I've raised a feature request for our development team to add this to the plist file by default. We'll update this thread if/when that is implemented.
