I believe you will need to install Catalina and then update to Big Sur from inside the Catalina install. The upgrade to Big Sur will also upgrade the recovery partition.I booted into internet recovery and wiped my drive, but now it’s only giving me the option to reinstall Catalina. How do I make recovery figure out that Big Sur is available??
Any chance you can grab an SHA sum of the installer app? Just run shasum -a 512 "path to installer"Downloaded and creating bootable USB key. Have fun everyone
For what it's worth they appear to be the same file. I downloaded the one from twitter and the official one via the App Store and they both get the same SHA256.There's a link above with a mirror to the Big Sur installation package. I would not download it!
It is not from one of Apple's CDN servers, as someone posted above. It is from a person who downloaded the package from Apple, and then reuploaded it to a server of the company that they work for (Scaleway).
I asked Steve Troughton-Smith if I should trust it. His reply: "I wouldn't"
An example official Apple link to the download (which does not work right now, because you cannot download an official Big Sur download at the moment) is:
The original source of the mirrored URL is this tweet:
SHA256(Install macOS Big Sur.app/Contents/SharedSupport/SharedSupport.dmg)= ae026c7cc877689749f4ed9b516f77db2248b81888ca862bf9031105f2bc813d
I kept getting fail message then a Safari 14.01 update popped up. I installed it and wham Big Sur download started. Not doing the happy dance yet...OK that was strange, now it is working and downloading. Hopefully no error messages this time.
Well, ****. LolI believe you will need to install Catalina and then update to Big Sur from inside the Catalina install. The upgrade to Big Sur will also upgrade the recovery partition.
