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... Paolo
