Im running an older high sierra based i mac and it seems to run slower with parralels installed. Especially on my own website Am i imagining things or is this a known fault with the software? Thanks
@WayneB4 Please provide us the screenshot of the virtual machine configuration to know the RAM allocation. Also, please open System Preferences > Security & Privacy > Privacy and open Accessibility. Make sure that box next to Parallels Desktop is checked. Do the same for Full Disk Access.
