Hi guys. I have been a Beta user for a very long time and this has been the worst experience ever.
Started with Beta 4 taking over 24 hours to complete, I'm now approaching 72 hours.
My MacBook Pro 15" is a souped up 2018 machine and I have tried the following.
- PRAM reset
- SMC reset
- Booting to Internet recovery
- Booting to recovery
- Booting via USB drive (with Catalina Beta 5 installer)
- Removing all security from my MBP via Startup Security Utility.
I can't boot from the USB drive. The result, after all this time is the same. I'm staring at a black screen saying "Estimating time remaining..."
So guys, any ideas?
