  1. Latitude E6220: BIOS A14, Core i5-2540M @2.6GHz, 8GB, Sierra

  2. I've been trying to install HS on my E6220, using this guide. But I can't get the install process to work. After creating the USB installer and booting up, the Clover Screen loads fine. Then I choose the "Install High Sierra" option with -v flag. Then it goes through all the commands and suddenly reboots, prompting the message "attempted to boot uefi volume from legacy mode" and going no further... Do you have any leads what to do? I've tried several times to create USB-installers, both with Clover r4689 and r5097 (with the latter, using the customized settings from the E6220 Mojave guide)
  3. lately i've been experiencing trouble with my keyboard. A couple of keys stopped to respond, working only after hitting it multiple times. if it was a single key I'd say it was a mechanical issue and get a new keyboard. But since it's a handful of keys (Left Shift, couple of keys in the upper letter row, Backspace) that acted up all at once, I've been wondering if there might be software reasons. Has anyone experienced this as well or does have any idea about this? I'm running a E6220 on Sierra with Enoch.
  4. Many thanks for the hint! I just started to do that and ran into a problem right away. After using sudo /Desktop/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/HSInstaller to create the USB installer I got the answer /Desktop/Install macOS High Sierra.app/Contents/Resources/createinstallmedia: command not found I'm not sure what went wrong here. The installer app has only a size of 23MB, though - am I using the wrong one?
  5. I have an E6220 i5 running with Sierra per Hervés guide with Enoch, everything running smoothly (except the need for a reinstall every couple of months ), but the HDMI output. When I connect an second display (monitor or projector), then Sierra can identify the second display but only shows a white screen on it. Any ideas what to do?
  6. Reinstalled it - three weeks running smoothly. And now it happened again: Header read size 200 Incorrect image signature, expected version 10.7 Why, oh why??
  7. OK, now, this is funny. I just did a complete re-install of my Sierra system - and guess what? Again this memory allocation error. Now I just tried to resize the background.png in /Extra/Themes/Default to match my screen resolutions and - voila! It worked. Strange that this seems to affect only my E6220..?
  8. So I'm probably looking at a complete ré-install here. I'm just afraid that I'm going to face the same problem again if I can't find the source of it...
  9. Sorry, I was confused. I didn't use Clover on my USB install disk, but Enoch.
  10. In that case on the USB installer's folder?
  11. IIt's just the same: Booting from SDD Bootloader into OS X SDD installation failure (header read size 200 etc) Booting from USB Bootloader into OS X SDD installation failure (header read size 200 etc) Booting from USB Bootloader into USB OS X Installer works, but apparently problems with Terminal access to SDD installation
  12. OK, I mounted the SSD partition with diskutil mount /dev/disk0s2 which succeeded ("Volume Macintosh SSD on /dev/disk0s2 mounted") But it didn't change anything on the outcome of the commands in Terminal...
  13. To rule out a misunderstanding: I was now booting from the USB installer into the Sierra installation menu and ran Terminal from there.
  14. The first command triggers this response: ls: /Volumes/Macintosh/var/vm/: no such file or directory Still tried to rebuild the cache and got "no such file or directory" for the first two directories, "read-only file system" for all the flags and "not a directory" for the last directory...
