Hello,
I have a MBP 2010 mid 15'.
I would like to install High Sierra.
But I can't.
I can install El Capitan, Sierra without problem.
I would like to do a clean install, because if I upgrade El Capitan or Sierra to High Sierra the usb ports not working well. If I plug usb drive sometimes nothing happens, or when I want to eject usb sometimes cannot eject, I have to turn off the machine, to eject.
I checked the system with ASD /apple system diagnostic/ and everything is ok.

So I would like to install High Sierra, I start from usb, and erase hard drive, after I want to install, but drop me error message:
"this copy of the install macos high sierra application is damaged and can‘t be used to install macos"
I checked in terminal /date/ the date is fine.
Only one different between this and those OS X which I can install: High Sierra time is UTC, sll others are PDT.
How can I change timezone?
In OS X installer the terminal do not know systemsetup, timezone commands.
So those are not working.

I created the usb 1 day ago, downloaded from the apple store, created with terminal command. Apple Support monitored how I create, he told me I am doing right. But they cannot help more because old system and not supported.

So how can I clean install High Sierra on my MBP?
 
I got it, the solution is:
Steps:

Go to your applications folder.
Find the installer for macOS
Right click on the installer and click "Show Package Contents".
Click on folder named "Contents".
Click on the folder named "SharedSupport".
Delete the file named "InstallInfo.plist".
Enter your administer password to confirm.
Now open the installer.

That said, if you have to upgrade to Catalina for specific SW, then you might be okay.

Otherwise, I would stick with Mojave.

BTW, this has nothing to due with the age of your iMac nor the specs, just that Catalina had brought a world of hurt to some users, and if you don't need to upgrade to it for any reason, I would just avoid it.

I cannot install Mojave or Catalina. My last supported OS is High Sierra.
I have MBP 2010 mid 15 inch. This is why I had to install High Sierra.

I am sorry, I was confusing your thread with another thread.
 
The reason why I was asking about SSDs, was that I was wondering if it could possibly be a firmware issue.

A few years back, I have experienced a firmware related issue that prevented me from installing High Sierra on a SSD that I added to a Mid 2011 iMac.

The iMac was a dumpster find and not working when I got my hands on it. The GPU was fried and the HDD was failing.

I fixed the GPU, and swapped the HDD for a SSD. I cloned the SSD from a Late 2011 iMac with High Sierra, and everything worked fine.

But, when I went to do a fresh High Sierra install, I was unable to. I was able to install up to Sierra, but not High Sierra.

After doing some troubleshoot, I discovered that it was a firmware issue. I couldn't upgrade the firmware either because it required an Apple OEM drive to update the firmware.

Basically, I had to reinstall a failing HDD, install High Sierra which installed the firmware, than swap the SSD in again, and I was able to install High Sierra on the SSD.
 
In my case there is no problem with ssd, as you can see on the video what I create it, and share it up, those things was my problem.
The Apple Support do not know how to create bootable usb with the new App Store app what they created /cannot download the OS installer, only a downloader aplication downloading from the Apple Store, not the full installer app/
And because of this, the Installer plist file is broken, this is why drop error message when you want to Instal it.
I put it all in one video :)
