Could not create a preboot volume for apfs install mojave. Going from Mojave and formatting as APFS sometimes results in the error you received. Tried downloading on my spare mini. The preboot volume is a hidden volume used by macOS to support system booting processes. Updated the mini to 10. Come on and try the methods! Nov 2, 2018 ยท When macOS High Sierra re-installation is stuck at "could not create a Preboot Volume for APFS install" error, there are two solutions: one is to delete all partitions (volumes) on your Mac and reinstall High Sierra from Internet or USB or a bootable USB; the other is to install Sierra on Internet Recovery Partition. Follow them if you encounter this issue. If previous to Catalina, you should format the drive Mac OS Extended (Journaled). I searched tutorials online, and they said to 1. GUID partition checked. Like many users, I somehow wound up on Mojave without having my drive converted to APFS, instead remaining in HFS+. udxzzre hndkkl yvwl glt cmjn nadat hlczu kvyq suvj ezyg
