Legend, thanks Jake.

OK so today I plugged my Apple Cinema 30" Display into my e6230. Before I plugged the monitor in I just had the Active USB powered HDMI to DP adapter into an active USB powered DP to Dual Link DVI-D plugged in. By having the "optimized for LCD" it makes the internal laptop LCD 1080. Any to my amazement - the internal laptop display is working at a higher resolution - higher than I thought possible technically on this display but it works....check the photos I wonder if this can forced permanently without the adapters plugged in? It works fine with Youtube and videos - no issues!!

I'm using your Clover pack. I'll check with the OC pack later today. I did notice a slight decrease in GB5 score when using 11,1 compared to switching back 10,2 after the update." I only did 1 test on each though, not a few tests though and average it. One glitch I have noticed off and on through out my E6230 experience is a flash every few seconds when going Full Screen in Youtube in Safari. I've noticed this with Mojave and Catalina but certain revisions/releases of the macOS would not cause the flash and I just stuck with them. I forgot all about it until I updated, it was the one glitch I fought with for a while. It's not going to stop me using BS though as overall I find it a more pleasant OS for day to day tasks. Although tbh I wish I stayed at Catalina at the release before the latest security update as that was rock solid. I could get back there but I'm too lazy as it would involved finding the exact revision as I'm sure if I used the Catalina install I had maybe 4-6months ago it will update to the latest security update bypassing where I was. Anyway...BS 11.2 working fine on your Clover pack, thanks again. edit: no BS is defiantly better for day to day. I like the separation of versions as I use Catalina for my work desktop. Keeps you in a different headspace

SMBIOS changed to MacBookPro11,1 to get around the the 11.2 update "Update cannot be installed on this computer". Will probably change back to MacBookPro10,2 but doesn't seem to be any negative effects so far.

Yeah It is strange. I hadn't changed anything from your packs which were functioning great before the update so I assume the framebuffer memory patches were applied. Yeah, Catalina is the past - the future is Big Sur on this machine...wow it is a lot smoother Just need to fill in the missing drivers to get Filevault working again then hopefully no more messing for a while - Thanks again.

Yeah I don't use a DSDT on my main desktop with Opencore, I don't even patch my SDST - I just use the premade ones. A few seconds added to my boot time is minor. The issue with your Opencore E6230 was that the Geekbench scores fall short. I think the best I got out of it was low 1600s I just installed with your Opencore pack and then replaced with your Clover pack and...I got a Geekbench score over 1700!!!!!!! Thanks again Herve, saved me a headache - I'm too lazy to fully go in on a opencore build myself as this is just my daily internet / YouTube machine. Interestingly I only went to Big Sur because I've noticed a painful glitch...the latest Catalina update...the security patch from a few days ago...it causes the horrible video glitches. I thought f#ck it, I'll just go with Big Sur instead of getting my old Catalina pre update installer out. I really shouldn't have been so stupid to update or without a cloned backup. I've noticed the same thing happens with Mojave with the latest update it had (few months ago update). Fortunately I rarely ever go in Mojave and don't use it for the internet so security patches aren't an issue. I've kept it one shy of the latest update to stop the graphics glitches. No glitches in Big Sur now tho so all good Thanks again.

Ah that makes sense as the guide didn't say to install VboxHFS/HFSPlus and I could't get Clover to see the Installer USB at first. I'll install with the Opencore EFI then copy the newest Clover EFI over. I stayed with Catalina as the Big Sur Geekbench results did not match it - there were quite a few errors I noticed in the Opencore guide. Opencore does not need a DSDT - it reads it from the firmware for example. I'm hoping if the Geekbench is 1700+ with the new Clover pack then I will stay with Big Sur. I attempted my own Opencore build and go very close with the Geekbench but not compatible to your Clover Catalina/Mojave packs with Clover. No, this is a clean install. As I already formatted my working Catalina partition ready to install Big Sur - I was without a working version of macOS to check over the clover install. I keep Mojave on a drive and use it over eSATA for one application that will never been brought over to x64 - it comes in handy in situations like this. Thanks for the tip, I'll read better next time. BTW Why are you using Chrome?

Followed the latest Herve install guide with Clover 5128 and the latest pack. Attempting to do a clean install on a APFS formatted disk.

Still getting 1400 Geekbench 5 results with OC vs Clover even with the patched tables and kexts vs the OC prebuilts. I'll wait for your guide and take it apart to see where I've failed.

Hervé - I've had that glitch happen on various build with the E6230. The solution I found was to clear the NVRAM. My memory (brain not RAM) is bad but I'm sure clearing the NVRAM with Clover wouldn't fix the issue - If you simply reset the BIOS to default settings - this causes a definite NVRAM clear, then reset the values (ACHI etc) and the glitch will disappear. When you say - "copied existing DSDT + CPU power management SSDT to the ACPI folder and all existing add-on kexts to kexts folder" Was this the existing DSDT, SSDT, Kexts from the Mojave Clover EFI Build? I'm assuming that is the case. Which is perfect. Your ACPI is the secret to getting a 1700+ benchmark over the 1400 with the OC pre-builts. I'll have another go at this now - Thank you for the -no_compat_check boot arg. Solves the issue perfectly. Merci.

Sweet. The only problem I had with Opencore vs your Clover one was - I could never replicated the 1700+ Geekbench 5 scores with Opencore. I'm assuming I needed to tweak the ACPI but it was easier to just stay with your Clover EFI. Thanks again for that.

I never got around to getting Opencore working on my E6230, was wondering if anyone plans to do the jump to Big Sur? Will it require a SMBios change or a patch to the installer keeping the MacBookPro10,2?

I feel so embarrassed, it was just the tracking speed that needed adjusting vs the sensitivity. @Hervé btw, I noticed when I updated my kexts that my benchmarks dropped. after reverting back to the versions in your pack I got back to about 1700 in Geekbench 5. Thank you again for that pack, it's perfect.

@Hervé Have you ever used FileVault? I turned it on my E6230 today and the machine no longer boots. I need to do some reading for that I think. (aptioinputfix kext)

I think the driver needs tweaking, works fine on my windows 10 drive with the same machine.
