Am new to mac world. and got a user who has mac probook(High Sierra). its running slow. freezes intermitently.
I googled and did few tasks, like clearing cache files., ran maintenance scripts from cleammymac3. checked for updates. still no luck. running slow.
From activity monitor found, calender agent takes around 1.06gb ram, kernel_task-959.5mb ram . how do i troubleshoot these 2 things. why its taking too much of ram ?
Could anyone help me with this.
