Hi Jeffreywsh,


Thanks for attaching the EtreCheck report. Please start a new discussion for your issue, as it may not be the same as OP's issue. Lag can be caused by various factors.


For now, I'd suggest doing the following:


  • Turn on Gatekeeper: Open System Preferences -> Security and Privacy -> General -> Allow apps downloaded from App Store and identified developers
  • Check Activity Monitor for symptoms (note the runaway process in the report), and troubleshoot in Safe Mode.
