Last night I decided to do a fresh install of 10.15.4 using the mini-guide that was very successful for 10.15.3 for me a few months ago. But I am getting the dreaded:
"An error occcurred while preparing the installation. Try running this application again."
I even tried preparing another (new) USB 32GB drive and the same thing. For kicks I went back to my 10.15.3 prepared USB drive (which now has been updated to Clover 5107 as well) and...no problem! Works perfectly.
Also, in both cases (the .3 and the .4 USB drives) Lilu, WG, VSMC and AppleALC are all at the latest.
I don't want to experiment around too much but if I have to I'll just go back to 10.15.3 and wait until we see the first update to .4.
Any thoughts? Thanks!
It may not be possible yet to perform a fresh installation of 10.15.4. For the time being I've made the following change to Catalina Mini-Guide:I got exactly the same problem when I tried to a fresh install of 10.15.4 using the mini-guide. I tried several times, all ending up with "An error occcurred while preparing the installation. Try running this application again."
Looking forward solutions.
