    Big Sur 11.0.1 regression

    Nov 19th, 2020: Apple released a statement related to severe issues affecting Late 2013/Mid 2014 13" MacBookPro. These are the Haswell MacBookPro11,1 models.

    https://support.apple.com/en-us/HT211242

     

    In order to prevent further widespread of the issues and pending an eventual fix, Apple released a new Big Sur 11.0.1 version (build 20B50) that basically excludes MBP11,1 platform from the list of supported Mac models.

     

    15" models of the same generation, i.e. MacBookPro11,2 and MacBookPro11,3 are not affected by this and remain on the list of supported platforms.

     

    The direct consequence of this on Hackintosh is this:

    1. Hackintosh computers running with MacBookPro11,1 SMBIOS can no longer obtain Big Sur as a software update or download Big Sur from the AppStore.
    2. Hackintosh computers running with MacBookPro11,1 SMBIOS must use the -no_compat_check boot argument to install Big Sur.
    3. A workaround to this is, of course, to run Big Sur with a different SMBIOS such a MacBookPro11,2 or MacBookPro11,3.

     

     

    EDIT: regression/bug fixed in Big Sur 11.1 (build 20C69).
