I had High Sierra installed on my 7450, but I screwed my installation attempting to upgrade to 10.3.2.

I tried to reinstall but had a lot of problems with the usb key, so I installed Sierra instead, it's a lot easier.

Now I'm experimenting a new problem. I can work with Sierra installed all day long and all it's fine, but when I reboot I have this error in verbose mode:

 

'The volume Mac os Sierra could not be verified completely'

 

And the boot fails.

 

I have to repair the disk in single user mode with this command, that I found on another forum:

 

fsck_hfs -Rc -d /dev/disk0s2

 

It works, but after a while the problem is again present.

 

I think it's related with the previous installation of windows 10 on the ssd. I had a lot of problems tryng to remove windows partitions (4) with disk utility. I had to erase the disk with diskutil eraseDisk from terminal, but I suspect that something is wrong on file system. Or is my  SSD near to the end?

 

There is a way to clean the SSD in an effective way and get finally rid of this annoying issue?

 

No, because i had no nvram.plist in EFI.

I tested the remedy but nothing is changed. It go to sleep after booting then it works flawlessly. Not a serious problem, the laptop is very usable. Thank you Bronxtech.

Thank you Bronxtech. I don't know how to disable rc scripts. I have OsxAptioFixDr-64, no emuvariable and no nvram.plst

USBinjectall did the trick. Now I have all three USB ports working. 
 
I have another issue with the screen. It becomes dark at the and of booting and sometimes I have to wait, than it goes on ´stop´ and after wake I have the screen again.
 
May be related to hibernation disabling?
 
Here is the output of terminal when I use the related commands. Something goes wrong.

MacBook-Air-di-7450:~ a7450$ sudo pmset hibernatemode 0
Password:
MacBook-Air-di-7450:~ a7450$ sudo rm -f /var/vm/sleepimage
MacBook-Air-di-7450:~ a7450$ sudo pmset hibernatefile /dev/null
Usage: pmset <options>
See pmset(1) for details: 'man pmset'
MacBook-Air-di-7450:~ a7450$

Only FakePCIID_XhCI_Mux? Not USBinjectall, right?

 

Thank you Bronxteck and Jake.

Thank you Herve´.

Now I have two files: ssdt.aml and ssdt.dsl. I suppose that I have to place the first in efi/clover/ACPI/Patched. Or is the second one?

 

Yes the USB ports are all Usb3. I admit my total ignorance about where to find FakePCIID_XhCI_Mux and above all how to install it.

In my lack of knowledge I simply extracted the zip file on my desktop and dragged the file ssdtPRGen.sh on a terminal window and hit return.

I managed to install HS on a 7450 i5-5600U. I followed the instructions by Jake Lo and used his last bootpack for A17 bios. I got good results, as my laptop runs pretty well on HS now. Thanks to this forum and Jake. 

Three questions:

1) in the post-installation process i tried to execute 'ssdtPRGen.sh-Beta', but terminal gave some error and didn't generate the aml file. Is that a problem?

2) One of the three usb ports doesn't work. Have I to flag something in 'kernel and kext Patches' on Clover Configurator?

3) I have a minor problem with screen luminosity at login (sometimes becomes dark a couple of times and I have to restore it with function keys. It's a common (little) problem?

 

Yes they are both on A11. It's an i3-3110M 2.4 ghz.

Revising Bios setting today I noticed a difference. In the I3 there is no entry for Turbo Boost.

I simply removed  'DisableTurboBoostBattery.kext' from Clover/Efi/kekts/Other/Le and from Library/Extensions. Problem

solved. Now boots and works with battery. Now I read on the net that my i3 CPU doesn't support Turbo Boost.

Here is a copy of the Efi with the kext removed.EFI copy.zip

Thank You Hervé.

Same thing happens to me. I have two E6230 both with Sierra installed with Jake Lo's guide 'Clover El Capitan/Sierra Guide'. One is an i5 and it's OK. The other is an I3, and it works only on AC adapter. It doesn't boot from battery. It reboots if I unplug the AC.

Same files for both, same config.plist, but different processors. Is it wrong? I swapped batteries, no change. Help nedeed...
