malkus 0 Posted December 29, 2020 Share Posted December 29, 2020 (edited) Registered over a year ago but this my first post! So, still here in the "lounge".. Since the 14th of december there is a full Big Sur download option via gibMacOS but still no recovery version though. I downloaded it anyway and now I wonder if I can use that content somehow to create a bootable USB. I already have a formatted stick with a boot partition with OC and the EFI-folder as well as large 2nd HFS+ - partition sitting there, waiting... Any ideas? The content of the folder from gibMacOS (001-86606 - 11.1 macOS Big Sur) is (with relevant (?) sub-content listed): BuildManifest.plist Info.plist InstallAssistant.pkg Bom PackageInfo Payload Scripts SharedSupport.dmg (12.2 GB) 0.MBR 1.Primary GPT Header 2.Primary GPT Table 3.free 4.C12A7328-F81F-11D2-BA4B-00A0C93EC93B 5.hfs (11.7 GB) Shared Support com_apple_MobileAsset_MacSoftwareUpdate SFR InstallInfo.plist UpdateBrain.zip 6.free 7.Backup GPT Table 8.Backup GPT Header InstallInfo.plist MajorOSInfo.pkg UpdateBrain.zip Edited December 29, 2020 by malkus changed date from 12 to 14 Quote Link to post Share on other sites

That still requires an internet connection for completing the install by downloading the rest of the rquiered data. I was hoping to put together a full, working offline installer.
