deeveedee Posted December 13, 2022 Share Posted December 13, 2022 (edited) My HackBookPro6,2 (patched with OCLP 0.5.2) notified me of the Big Sur update Big Sur 11.7.2 Update Available Spoiler The upgrade applied virtually error free. The only minor issue was that OC boot picker did not automatically choose "Install macOS" after the first installer reboot. Note that updates on unsupported hacks require installation of the full update (not incremental). Downloading new updates Spoiler After installation, OCLP automatically prompted to apply Nvidia graphics patches OCLP prompt to install patches Spoiler Big Sur 11.7.2 installed and running on this old 2010 Dell Latitude E6410.

MacNB Posted December 14, 2022 Share Posted December 14, 2022 (edited) Updated my Legacy BIOS Dell 530 system to Big Sur 11.7.2 with Over The Air update...only 2.54 GB in length ...no need for full installer: What I do BEFORE checking for updates in Sys Pref, I set the "VMM Flag" to ON in Root::Kernel::Emulate::Cpuid1Data like this (and reboot): I always receive OTA updates not full 12GB+. Once updates are done, I set VMM to OFF as it apparently hits performance by 5%-10%. Sometime I forget but I've not noticed any performance drop. I keep copies of ON/OFF flags in the config file handy (# comment tag). Updated successfully after several reboots without any interaction. Emulated NVRAM working well...pickinup "macOS installer" automatically 🤞 I also boot Monterey on this system and it too is awaiting an OTA update. As I recently replaced my GT730 GPU with RX 460, there's no need for OCLP since RX 460 is natively supported by Big Sur and Monterey. The system can now easily play & encode both HEVC & H.264 video files via the RX 460. Still life in the 12 year old girl 😁 Edited December 27, 2022 by MacNB 3 1 Link to comment Share on other sites More sharing options...
deeveedee Posted December 14, 2022 Share Posted December 14, 2022 (edited) @MacNB That VMM Flag trick looks great! I'll have to try that. Another reason why I'd like to have user-selectable config.plists (at boot time) for OpenCore. Also, let me know if you figure out how to install a RX460 in my Dell laptop Edited December 14, 2022 by deeveedee 1 2 Link to comment Share on other sites More sharing options...

FirstTimeCustomac Posted December 14, 2022 Share Posted December 14, 2022 Nice!! I will also give VMM flag a try. It's a shame that full AMD HEVC encoding in FCPX and Compressor only worked in Mojave. Link to comment Share on other sites More sharing options...

The VMM flag is not well documented in OC but worth a try. 43 minutes ago, FirstTimeCustomac said: It's a shame that full AMD HEVC encoding in FCPX and Compressor only worked in Mojave. Going off-topic here but let me briefly explain it's not quite true what you say: I add shikigva=96 unfairgva=4 shiki-id=Mac-7BA5B2D9E42DDD94 to the boot-args in the Root::NVRAM::Add::7C436110-AB2A-4BBB-A880-FE41995C9F82::boot-args and can run FCPX 10.6.5 on this old rig running Big Sur. I believe shiki-id=Mac-7BA5B2D9E42DDD94 is no longer necessary as the other two args do the same board-id swap. You need Whatevergreen kext. FCPX uses the RX 460 for both Encode & Decode of both HEVC and H.264. However, the size of the HEVC output is more than 2x the size of H.264 encode making it useless since the whole point to HEVC was to reduce the file size. I have not yet figured out why. So it does encode HEVC but the file size is too big. To get it to encode HEVC, I setup a CUSTOM output profile in Compressor and from FCPX share the output to that custom profile. The key is to uncheck "Allow Frame Reordering" to allow FCPX to output HEVC: As I said, this discussion is off topic in this thread but welcome to open another thread to continue.

FirstTimeCustomac Posted December 14, 2022 Share Posted December 14, 2022 @MacNB Thanks this worked, I no longer have to change SMBIOS to iMacPro to get delta updates!! Thanks you. IIRC. For me, FCPX 10.4.6 and compressor 4.4.4 on Mojave were the only ones to fully utilize polaris for HEVC encoding on iMacPro1,1 SMBIOS as I checked GPU usage in activity monitor. And encoding time on same project kinda confirmed it. But I'll try out your suggested settings. thanks. Link to comment Share on other sites More sharing options...

I use iMac14,2 as my Model-ID and that's why those boot-args are needed which overrides the board-id to that of iMacPro1,1 so that I do not have to change the model.

I did try R5150 on this Legacy system but could really get it work properly (e.g. APFS loader efi driver would not load but hang the system and I had to use apfs.efi instead but throws out a lot of verbose screen output). Clover uses OC parts anyway so I gave up and sticking with OC. 1 Link to comment Share on other sites More sharing options...
