Mouse lag is almost always caused by high cpu usage. Does Activity Monitor show high cpu usage for BTT? If so that is most likely an issue with the 27.2 beta: > [@High CPU utilization in macOS 27.2 Public Beta](https://community.folivora.ai/t/high-cpu-utilization-in-macos-27-2-public-beta/47865/4): > > If you encounter the issue again please run this terminal command: sample BetterTouchTool \> ~/Desktop/btt.txt Afterwards post the btt.txt sample here or send it to [andreas@folivora.ai](mailto:andreas@folivora.ai), it will tell me what is causing the high cpu usage. Often beta issues resolve on their own with the next beta release though. --- _[View the full topic](https://community.folivora.ai/t/cursor-lag-stutter-macos-27/47888)._
