Hi Martin, I am currently running your OC 0.6.3 package with wifi fix to run Big Sur on my 5,1 MP. Thanks!!

So thinking about updating to OC 0.6.6 Can I just replace the BOOT and OC folders with the ones from your 0.6.6 package to update or will that run me into wifi (or other) problems?

If you need the wifi fix, you can replace the BOOT and OC folder, then follow the video guide to enable legacy wifi support, then reboot.

Thank you both for the quick replies.

I currently still have SIP disabled. Would that be an issue? And... I wonder what is a best procedure, to re-enable it after successfully running OC via the (wonderful) package from h9826790?

Post #1314 now has a video guide about how to re-enable SIP.

I assume this is the video you are referring to?
 
Do we need the OC 0.6.6 for Big Sur to function properly? I ask because I am running Big Sur on my OC 5,1 MP, updated to Big Sur 11.2 and am still running OC 0.6.3

I see that 0.6.3 has the Mojave and Catalina Kext, but 0.6.6 only has the Mojave Kext.. is any of this relevant to running Big Sur properly?

I ask this because I have been experiencing the following:


In iStat Menus i can see my GPU Ram (RX580 8GB) is always maxed out.

Video works fine initially, however I am noticing slower graphics in Logic Pro X (meters lagging for instance)

However I can see the vRam steadily climb all the way up to 100% after about 1 hour working on just spreadsheets and web work, not doing anything graphically intensive

CPU Usage always very low. Ram (24GB) also is low, always have about 15GB to spare.

What could be causing this? I think this issue maybe causing my graphics in Logic to lag and, eventually slow down system response visually.

No "need" to update to OC 0.6.6, but I highly recommend to 0.6.6. e.g. it provide DRM streaming. Even you don't need it, but still worth to have this function properly activate in an OS.

I also found that some Big Sur UI may shows laggy after a period of time. For applications, simply close it and re-open can fix it. But if a generic slow down, then a reboot is required.

However, it isn't that bad on my cMP. It's generally responsive.

For VRAM issue, I highly suspect that's due to HiDPI. What you see at this page?

Hi Martin, not wanting to hijack the thread with Trim/SSD but a quick question for you regarding the new SetApfsTrimTimeout in OC6.6. I have presently set this to 9999999 so giving the Apple default of 10 seconds. However, reading the manual and seeing you have used 999 which effectively disables the trim operation on startup I am wondering if this would be better for my cMP. I do not have any issues but my system is using Samsung SSDs. Many thanks for your excellent work.
 
Running Mojave via RefindPlus/OC v066 on my MP5,1 and VideoProc shows full hardware acceleration. However, testing this out today by converting an MKV to MP4 file, my Vega 64 only shows 3% utilization and Video Proc only has Intel and CPU displayed under Hardware. AMD is grayed out - Hardware Info also shows GPU as N/A. See screen shots:

I was assuming that everything would be parsed over to the GPU but it doesn't seem to be the case. Looks like the CPU and GPU are sharing the load. Do I need to alter something here to improve performance?

I've got a lot of freeze reboot since I update to latest opencore mod made by Martin.
And it doesn't say "you had an error your mac had to reboot"
Nothing...
It freeze and reboot...
Something related to OpenCore or not?
I have HWaccel, RadeonBoost, and TB enabled.

EDIT : I just saw there's improvment in sys report in Big Sur 11.2 : Thunderblot is named now Thunderbolt/USB4

Thanks for helping out!

My setup looks like this:

It just skip the manual TRIM during boot. TRIM still works inside the OS.

EDIT: and ffmpeg still shows a significant amount of activity that the GPU should have taken over:

Post #1 Q28

177 FPS with that low CPU loading. Apparently GPU was doing the encoding.

And CPU was doing the decoding part, that's why there were some load on it.

Thanks for replying. Why isn't the Vega 64 getting loaded to a 100%, or do I need to throw something harder at it, like 4K video?

That said, shouldn't GPU do decoding as well?

The video engine is just a very small part on the die. The GPU compute / 3D engine still idle. Therefore, the overall utilisation rate is very low even when you are using HWAccel.

It's the software to decide use software decode or hardware decode.

I did the opencore and Im getting no boot screen. Its just a black screen as it was before. The only difference I see is that when my display finally shows something, I can see a apple logo and progress bar at 100% before it brings me to my login. Also how do I update to mojave with this opencore?

Specs:
High Sierra
12 gigs ddr3 1066 ram
Dual xeon e5620
ATI Radeon 5670 1G
Sata SSD (not PCIe)
cMP 5,1 (Mid-2010)
==================

This is my drive below. I ran the Bless Drive thing and added the "Boot" and "OC" to that drive, Whats going on?

Ok update. I found a "Install Mojave" Installer in my applications folder. So something did happen, I just dont have a boot screen so I dont know if it will install correctly. And how will this run on my non-metal card?
 
OK so take note. I dont believe you can change it but this is awkward as heck.

The primary purpose of the OpenCore package in this thread is to provide HWAccel, not running unsupported OS with unsupported GPU.

If you don't even have a Metal supported GPU, you better use DosDude patcher to install Mojave.

Anyway, my own suggestion is to get a supported GPU, then install Mojave natively.
