download Big Sur from apple store.

I've tried this before, but it always redirects me to system preferences, you probably were on a version of macOS below Mojave when you did that. You have to download the InstallAssistant manually from this link if you are on Mojave/Catalina/Big Sur. http://swcdn.apple.com/content/downloads/04/34/071-00838-A_16DMRFYPPS/g072hb2wh066rj040ekzry97wx2hggfuse/InstallAssistant.pkg

@BenSova I use the MacBook Air witch support Big Sir that's why I was able to download Big Sur from apple store and made USB installer in the MacBook Air.

ghost commented 3 years ago

That still opens system preferences from my experience.

toshibochan commented 3 years ago

Try hold opinion key and press to download

toshibochan commented 3 years ago

@ross104 you was able to install?

ross104 commented 3 years ago

Just finished installing it. Tried lots of times, but rebuilding and repatching usb did the miracle :)

toshibochan commented 3 years ago

Is very important how erase usb drive to make the installer. If all working please close this.

ghost commented 3 years ago

Try hold opinion key and press to download

Same result. The direct download link works for me though, it's not hard to find.

It's good that it's working now! I agree, close this since it probably was just a one time bug with out you made the usb.

toshibochan commented 3 years ago

@BenSova Your Mac you trying to download is compatible with Big Sur?

ghost commented 3 years ago

I've tried it in both a compatible and incompatible state. It's probably a Mojave and above vs. High Sierra and below case.
