Hello guys, I am very happy about my E7440 running High Sierra, however I experience an issue while connected to two external monitors. I connect using the HDMI port and a Mini DisplayPort to DisplayPort adapter. This works great, but when the screen is locked, or when the system goes to sleep, the system crashes and shuts down. Without any external monitors connected this problem does not occur. I am using the bootpack from the Clover guide along with Lilu.kext, Shiki.kext and IntelGraphicsFixup.kext. After reading this topic, I was thinking that this might have something to do with my current SMBIOS ProductName (MacBookAir6,2) or with the current VRAM amount (1536MB). I tried looking up the error in system.log, without any luck. Is this a known problem, and would changing the VRAM or ProductName solve this problem? Thanks!

Lads, I've successfully managed to install Mavericks 10.9.4 with a Clover USB. I updated to 10.9.5 flawlessly through the AppStore. My E6410 is a nVidia variant, updated to the last BIOS (A16), and the system feels quite stable...the notebook heats up a bit more then usual, but that is out of scope right now. Initially, after the setup went well, i tried installing Clover UEFI on my GPT Disk, however, this notebooks UEFI implementation is whack, i tried every possible EFI file entry, uppercase lowercase backslash frontslash, ubuntu/windows masking, whatever was left to try, googling UEFI for E6410 ends up showing people moaning how shitty the UEFI implementation from DELL is...so i left this as a dream for the future, i can live without it. After that, i wiped the EFI partition with this command "newfs_msdos -v -F 32 EFI /dev/disk0s1" (disk0s1 might differ to your setup, careful), after adding -F 32, things got better and installing Clover with MBR bootloader (boot0ss) boots the system. I ended up copying my USB's clover settings as it wouldn't boot my system with the default one, so that will require further investigation...but yea, it works . i used Clover Configurator to load extra EFI drivers for Clover...very handy tool, and also placed the DSDT to the /EFI/CLOVER/ACPI/PATCHED/ folder... so from this build, i have witnessed a few catches: first, battery monitor is inconsistent, a lot of times battery percentage freezes, and only a reboot will give it the right numbers, however, it rarely works as it should. Audio suddenly disappeared, rebuilding caches didn't help (Kext Wizard) so i installed the VoodooHDA manually, even though it is on the /EFI/CLOVER/KEXTS/10.9 folder present. after the kext install, audio is back. (also happened during the 10.9.5 update) External Displays, i definitely need VGA for work, and DisplayPort for home, none work so far...my pure guess is DSDT, but as i said, it is a guess. care to help me guys, this thread could end up being a guide for clover thanks in advance Pluto
