You can roll back to an earlier version of Windows.Unfortunately i can't, because i already installed 1903 on my MacPro mid 2010 If I replace the MacHALDriver.sys file in this C: / Windows / System32 / drivers / MacHAL Driver.sys directory with a new one, from that user on this web site: https://virtuallyfun.com/wordpress/2019/05/26/wdf_violation-on-apple-macintosh/ (his name is Gerlin Miguel Nolasco Hernandezdamage) maybe can my system destroyed or not ?
P.S> Download the new MacHAL Driver.sys file you can hea(guy name Gerlin Miguel Nolasco Hernandezdamage): I beg in you please test if you can on some MacPro mid 2010 PLEASE. I can risk and because i have a lot of very important data on my Windows 10 partion. https://mega.nz/#!TrIhmQqA!bPX5u934PCjRHq5TOcpwiPHOV_sMIrUeKGUDVo37pTY
