Update Bar every boot
I'm operating a MacBook Pro with Mojave 10.14.5 and every single time I reboot my machine the update bar shows up and goes through the process and then eventually gets to my desktop. I'm wondering if there's a way to find out what is trying to update and also be able to get it to stop. Since this has started my Mac gets that frustrating rainbow circle happening more often too.
Thanks for any and all guidance / help.
MacBook Pro 15", macOS 10.14
