MacBook Hot to Touch

Hello deena2494:

Perhaps there's some runaway processes, applications and/or third party utilities

or an unnecessary anti-virus app. Best to at least check by use of Activity Monitor

and as needed, shut those runaways down from Activity Monitor.

• Activity Monitor User Guide (( Table of Contents )) - Apple Support

https://support.apple.com/guide/activity-monitor/toc

Anything important there should be available again on restart.

Symptoms of hyper active systems include malware, adware,

among other pesky things acquired through browsing; or use

of those anti-virus scans that run in background. The fake kind.

As with anything on Mac, be sure to have & use Backups.

To include those made by Time Machine on external USB.

Good luck & happy trails! ☺︎
