    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.

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

    MacOS Big Sur is out

    Released November 12th, 2020 as announced.
    Version 11.0.1, build 20B29
     

     

     

     
    Officially, this drops support for Ivy Bridge systems with Intel HD4000 graphics to raise the minimum requirements to Haswell graphics. Yet, as per all beta versions, Big Sur 11.0.1 still provides all the drivers required to support HD4000 graphics so it can be installed and run on such platforms with full graphics acceleration.
     
    nVidia Kepler graphics remain fully supported. A notable exception to these specifications appears to apply to the iMac14,1/2/3 (Haswell models with Iris Pro 5200 or Kepler GT7x5M graphics) that all appear officially unsupported.
     
    Also released at the same time:
    High Sierra 10.13.6 Security Update 2020-006 (build 17G14042), which should be the last one, High Sierra reaching end of support. Mojave 10.14.6 Security Update 2020-006 (build 18G6042).
