For Catalina only, run sudo mount -uw /.Fortunately, after a week of no crashes, I felt the need to write up my findings!
#2018 MACBOOK PRO THUNDERBOLT PORT ISSUE DRIVERS#
There was one suggestion to remove a dozen drivers but this seemed careless, I cherry picked a few and hoped for the best.
A lot of threads online suggested one driver but my laptop continued to crash (very infrequently). Looking for a permanent fix, I found that you could disable certain drivers. Very quickly I learnt that the issue was with the thunderbolt port and has been speculated that it was introduced with an OS update.Ī short term fix was to always have something plugged into the thunderbolt port (I had a spare ethernet converter) but after a few days, it did crash. I did eventually get a Genius appointment and had a battery replacement which did not fix my problem but at least my battery would last a suitable length of time (assuming no crashes!)Įventually after months of having this issue, I finally had a crash report which gave me the necessary information. Disable/remove network properties including VPN.Audit all apps (removed where possible).Rather than go to the Genius Bar, I tried the following: At the time of this issue starting, I had a battery condition message appear so naturally I connected the two issues. These issues tended to occur when the laptop was not connected to the mains. More often, it would crash 3-4 times a day. Sometimes it would crash once a day, other times it would be upwards of a dozen. I would boot the machine and have no crash report. The problemĮvery so often my laptop screen would go blank, there would be 8-9 seconds where the fan would go wild and then everything would power down.
I have updated the steps below accordingly. UPDATE: This issue occurred again for my MacBook Pro 2014 following an update to Mojave 10.14.6 and again for Catalina 10.15.2. Over the last few months I’ve been managing to live with an issue with my MacBook Pro (Retina, 15-inch, Mid 2014).
