Hi. Guess I get to join the party. My late 2013 MBP 15 has been shutting down. Using High Sierra.
I tried a lot of the suggested fixes I could find online with no success.
It would run ok and not crash if I had my audio hardware plugged into thunderbolt. If I unplugged, it would crash in a matter of minutes. I turned off the Thunderbolt /Ethernet ports in Sys Pref, and that seemed to work for a while. But, instead of entering sleep mode, it would shut down. Thought it was working enough to bring it to work (where I dont have a TB device) and it shut down within minutes of turning it on. UGH!
Currently, I have the TB/Ethernet ports set back to “using DHCP”, but I decided to shut off my wifi (I’m currently typing on my work PC). My Mac is currently not shutting down, until I turned the wifi back on, then it shuts off in minutes.
So, no TB plugged in and wifi OFF and machine acting stable. I’m curious if anyone else has had things stabilize by turning off wifi. And further, what this means for me and my MBP.
Thanks
