acetuk Posted April 30, 2021 Share Posted April 30, 2021 I am hoping to have some time over this weekend to try to get my HP840 G2 upgraded to BS 11.3, ideally with the latest release of OpenCore. Has anyone tried it yet? And had a success? I can see that there are a number of changes in the latest release of OpenCore and I need to work through what impact they will have on the current configuration that we are using.

I always modify the keyboard so that it works like in windows and it does not matter to me that the ALT key and windows kay are changed. Sorry I haven't had chance to post a reply - your changes worked perfectly and opencanopy is working. I made a small tweak in macOS directly to get the keys back to how I had been using them and the device has been very stable ever since. Link to comment Share on other sites More sharing options...
acetuk Posted May 1, 2021 Share Posted May 1, 2021 A quick update from my work tonight. I updated all of the kext other than the Voodoo set to the latest versions. BS 11.2.3 continued to boot as expected. I then used the latest version of SuperDuper (3.5.1 beta) to clone my main drive. I put my EFI folder on to that drive, put it in my HP840 and it booted fine. Using that drive I successfully upgraded to BS 11.3 without any issues. I put my main hard drive back in to my HP840 and also upgraded that without issue. I haven’t tested things too far but the laptop boots fine, wifi etc. is working and the device feels snappy. This was all using OpenCore 0.6.7. Now that I have my device fully up to date I can see if OC 0.6.8 is an easy step to take. I fear not. Link to comment Share on other sites More sharing options...
zerking Posted May 17, 2021 Share Posted May 17, 2021 First of all, thanks @Axon_80 for your EFI, I was able to boot my 840 G2 machine to OS 11.3.1 But I'm facing a couple of issues: - Machine can't sleep cuz it won't wake up - Losing trackpad after sleep, and it took several boots to get it working again (honestly I don't even know why it works again) - Boot time is longer than usual. I'm using SSD and boot time with previous OS aka High Sierra was significantly fast. Thanks all members for your help and contributions. Link to comment Share on other sites More sharing options...
