My 2019 iMac 27” running Mojave 10.14.6 with security update 2020-007 installed has recently started crashing every single time it goes to sleep or is put to sleep. These crashes started happening 10 to 14 days after installing the last security update (14 Dec), and I’ve installed no other software in the meantime.
I’ve tried putting the Mac to sleep after a safe reboot and after disconnecting all peripherals—still crashed. I’ve run Apple’s diagnostics with no resulting error codes.
There are massive amounts of discussions regarding similar problems but they are either generally centered around Catalina, which I’ve never installed, or T2 Macs, which my model is not.
I’d greatly appreciate any insight or advice regarding this problem! Thanks.
