Trouble doing clean install of 15.3 onto new external Thunderbolt 3 SSD
Tried to install 10.15.3 Catalina clean onto new Thunderbolt 3 SSD drive. The installer is on an external USB drive.
The SSD drive light was on but there was no progress on the progress bar after several minutes. I've tried three times with same result. Installer created a macOS Install Data directory and restarted the iMac (10.14.6 with today's updates).
Any suggestions? I've sent a problem report to the manufacturer(OWC).
Here's the info on my iMac:
