try rolling back USB kext, assuming your using thumb drive. USB errors. Can make small sata partition for installer instead as possible work around too.

    • My rig is not booting without the "XCPM bootstrap patch" and "xcpm_program_msrs (c) Pike R. Alpha" patch. Already tested that.  Booting without the TSCAdjustReset.kex is working great and booth sleep and wake is working. The new bios 0603 has an updated microcode and that might be the reason  for the fact that everything is working as it should without the kext.
    • Hello folks,   I may be a privileged user since i own a real mac aka a MBPro 15" mid 2012 runing fine HS... So i wanted to try a personal tip: I hooked my Sandisk 100 GB USB SSD to the real Mac and performed a clean install of High Sierra on it. Then i installed the latest CLOVER on this USB disk and copied the Urashimataro previously provided EFI partition. Then i pluggued this USB to my Xiaomi laptop i5 and tried to boot from this USB SSD. INCREDIBLY BUT TRUE: YES it worked fine. ;-)) Of course i also removed the serials to put mine previously blessed on Sierra...   Happy to share this new tip that lets me boot again my Xiaomi laptop on MacOs, and proud for my own personal solution, since i couldn't retrieve here any workable solution and it drove me crazy and nuts...   Enjoy!
    • Venduto altrove potete chiudere
    • I share your folks pain. Every step forward seems to be two steps backwards in other areas. And at the same time it's soooo worth it with features most forum users are not fully aware of ... yet  Anyway, it would be nice if you could fix this:    Your previous content has been restored.   Not only cannot post as I keep seeing it; the 1st time I saw it also 'restored' (read: removed) something that took me 1 hour to put together. It was a post reply with a quote and image attachments in it. Btw using imgur for external images ain't working either.
    • Hello again @obus.  Hello, everyone. Perhaps, you should now try without any patches for the CPU...? (at your own risk) ... of course only with tsc sinc kext, if now you have an official BIOS v.0603
