I'm up to me neck in it just lately. I have a new 1TB SSD that was fitted by a repair man with High Sierra. It's been going OK but today I booted up from the external spinner drive with Sierra installed via startup disc. I used an app that I can't get to work on the new drive, but when I went to reboot from the internal SSD, it wasn't there either in startup disc or disc utilities. I tried several times and ended up shutting down and then disconnected the external and hoped to start from there. No such luck; I got the start up sound and then nothing but a flashing question mark which I know means it can't find a drive. I've plugged the external drive back in and it's started up, but still not showing anything but the external drive in startup disc. I'm wondering if this has anything to do, either with an apple security update I put on this morning or that the new SSD internal will only show up on High Sierra.
