ProBook 450 G5 i5

@the3rdknuckles Can you share your efi folder? I have a 450 G5, but I cant seem to get to the installer.

I can’t. I had to restart everything because it wouldn’t boot into OS X anymore.

Have you had any success? I keep getting a KP just trying to get to the installer.

I’m gonna have to start from scratch and that won’t be until the weekend after next.

Can you share your EFI?

The laptop came with 8GB and I added another 16GB (I want/need to be able to run a lot of Docker containers in Kubernetes, so the extra RAM is important to me). I don't think it is necessary for general use.

Sound works through the speakers. I followed "standard" guides and inject "3" (config.plis ➔ Devices ➔ audio). I have sound through the speakers and over HDMI but not through the headphone socket. I would like to get that working again. It used to work but got broken along the way. I think it was when I followed RehabMan's guide and used the utility that installs AMLs and Kexts, etc. That got the backlight, power control and volume buttons working, but I think that's when the headphone socket failed.

I am now trying to make the laptop more secure - it has to be lockable and the disc needs to be encrypted.

Yeah I can’t help you out. The new update for Mojave won’t load on my laptop. It says it isn’t compatible. So I’m SOL rn.

It says it isn’t compatible

Try booting with -no_compat_check

Try booting with -no_compat_check

Thanks for that info
Edit I was able to get to the disk Utility thing but it won’t let me install in on the drive even after I formatted it. The drive is greyed out. And it says the version 10.14.5 is not compatible.

@the3rdknuckles I have managed to install Mojave on my HP Probook 450 G5. Everything is working. I am attaching my EFI folder to help you. Hope it helps.

Problem is I can’t install the new 10.14.5 is says incompatible with hard drive. I tried getting 10.14.4 and lower from apple, but they are .dmg files and not .app.
