[solved] Problem on Creating USB Installer High Sierra for Laptop

[soeryobadja]

Hello @RehabMan

I am in process of making a Hackintosh on my Lenovo T440 laptop, with guide by @Sniki

I have created my USB Installer of High Sierra, using createinstallmedia method as described in your post.
======
[Guide] Booting the OS X installer on LAPTOPS with Clover
======

I have successfully created the USB installer, but once I install macOS on my laptop, it said "the installer is corrupted and cannot be made to install".

I made 2 USB Installer, one with my MBP running 10.8.5 to produce a 10.13.3 installer, and another one with my Hackintosh running 10.13.3 to produce a 10.13.15 installer. Both result in the same error.

What did I do wrong here?

Thanks.

The Mac App Store only has 10.13.6 available for download.

Your installer certificate might have expired or installation damaged.
Why not download the 10.13.6 and install it ?

Hello @Sniki

Thanks for replying.

I had my 10.13.5 installer, previously used for installing on a Macbook Air with good result.
Turns out, problem was caused by my BIOS date. After flashing BIOS-mods for whitelist, no date and time reference, so I need to go back to my Windows HDD to set the date and time, and then replace HDD with SSD to make a fresh install of High Sierra according to your guide.

After installation, I encounter some problem which I shared in the T440 thread. Hope you don't mind to take a look and advise further.

Thank you for your support.
