uptime

" alt="type the below command" width="640" style="max-width:100%" data-src="/uploads/20240914/172630520766e553b7725a0.jpg" data-srcset="https://www.guidingtech.com/wp-content/uploads//Check-Your-Macs-Uptime_7-1024x655.jpg 1024w, https://www.guidingtech.com/wp-content/uploads//Check-Your-Macs-Uptime_7-768x491.jpg 768w, https://www.guidingtech.com/wp-content/uploads//Check-Your-Macs-Uptime_7.jpg 1224w" data-sizes="(max-width: 640px) 100vw, 640px" />
