How to play audio in Safe Boot? I am having an issue recently which causes my MacBook Pro 2015, 15", to spontaneously (and randomly?) shut down.

These shut downs do not happen in Recovery Mode or Safe Boot.

Temporarily, before I am able to identify and fix the root cause, I would like to continue using my laptop.

I am actually very happy using Safe Boot for now, I can do almost everything I want to do.

However, I can't figure out how to enable audio output while in Safe Boot mode.

I know it's not really intended, so possible workarounds may be awkward, but how can I hear the sound output from my MacBook while it is in Safe Boot?

The only external speakers I have access to are my iPhone 7's (iOS 13.3) and lots of pairs of headphones (although idk if those count as "external speakers"). I added this information because I wonder if it's possible to stream the sound output through my iPhone perhaps (network connectivity seems to work fine while in Safe Boot), if it is indeed impossible to play audio on the MacBook while in Safe Boot.
I have the exact same problem with my 15&quot; mid-2010 MacBook Pro.  It does not suddenly reboot when in Safe Boot-- only in the normal boot.  Apple is aware of this problem but will not assign even one engineer to look into this problem as I have been complaining to them for over 6 years about this.
I was told that possibly the battery needs to be changed-  but Apple stopped making batteries for this model years ago.
So, theonlygusti, if you change the battery and it works properly or not, please let me know. I'll be very appreciative.
