My understanding is that only disable TRIM during boot.

Anyway, you can re-enable it by setting SetApfsTrimTimeout to 4294967295.
With this value there is quite a long pause at boot.

In @cdf's main OpenCore thread, the suggested value is 9999999, which is 9.99 seconds. Does this suggest the value you gave equates to 4294 seconds (72 minutes)? In any case, the delay with my machine is more like 2 minutes.

If possible, 10 seconds seems like a better compromise, even if it doesn't get everything trimmed within that time. I may have misunderstood what this value relates to, though.

Could the issue with my 960evo m.2 drive seemingly not trimming blocks be that its firmware doesn't trim automatically in normal use (perhaps due to considering the system 'busy')? So if it doesn't trim at boot, it never does?
 
The latest 0.8.0.2 config file has AVXpel included (credit to Syncretic)


This config is for the 0.8.0 package, all you need to do is just replace the config file with this one.
I had been using your previous updated config file for 0.8.0. From doing a quick diff, it seems the only change is to update the MaxKernel values, so it works with 12.5+?

As I'm on 12.4, I assume there would be no change? In that case, AVXpel was already active, and my freezing issue must lie elsewhere. It's been OK so far today though.

That’s correct, the last config update is mainly to enable AVXpel beyond 12.4.

Before you consider go back to 12.3, may be you can go 12.5 to see if there still any freeze.

Update is easier than downgrade this time. Also, if that work, the newer OS should has better security.

You can change that value, but in Monterey, that’s either on / off, the value (other than zero) shouldn’t make any difference. Of course, nothing stop you to try. It should be very safe to try a smaller value.

I have a net friend monitored TRIM activity in MacOS. And what he found is that TRIM does work from time to time, not just at boot. However, even quite a bit of idling time (computer on 24/7, TRIM may still only work once every few days).

I personally haven’t try to monitor that yet, but you can take this as a reference.
 
My Mac has been suffering from regular freezing for a couple of weeks, with spinning beach balls, even with very low CPU usage. I’ve also had issues with Windowserver crashes, particularly at login after sleep.

From a little reading around, it seems 12.4 included increased AVX instructions. Syncretic created AVXpel to counter this, but I believe it’s not included in @h9826790 Martin’s 0.8.0 OC? And even then, may not be foolproof?

At this point, would it make sense to just revert to 12.3.1? If so, what’s the easiest way to go about this? Would I need to wipe the whole disk, install 12.3.1, then restore my files from Time Machine? Or could I downgrade the OS container via Recovery somehow?

Also, I can’t seem to enter Safe Mode. If I hold Shift, then press and hold Enter (to select macOS) at the OC boot picker, the OS starts to load, only for the computer to reboot back to the picker again.
Its really easy to add Syncretic's patch to your config. But it doesn't sound like thats your problem. The patch prevented kernel panics... not beach balls and windowserver crashes.
 
It ended up freezing constantly earlier, and black screening with a mouse cursor on wake. I then updated to 12.5.1 (with Martin's latest config) and it's been faultless since. Will keep the champagne on ice for the moment though - it'll take a few days to know if updating sorted it.

Edit: still having problems with 12.5.1. It was good for a few hours, but then had a phase of getting beachball pauses. Occurred with Adobe apps, opening Safari tabs, and general useage. It also sometimes freezes and / or spontaneously reboots at the login screen after sleep. After the latter, I get an error report that references the WindowServer.

So far I've tried:
- Resetting the NVRAM
- Reflashing a clean BootROM (the existing one was in excellent condition per UEFI Tool)
- Resetting the SMC
- Reinstalling 12.4 from Recovery
- Installing 12.5.1
- Repairing the disk
- Repairing permissions
- Running all maintenance options in Onyx

I don't think it's hardware (a reboot always fixes it for a bit), though can't rule that out. It's driving me nuts.

I'd boot in Safe Mode, but can't figure out how to do it with OpenCore running. I've tried holding Shift and Enter+Shift but neither seems to work (and the latter just results in a reboot before the login screen).

I do have quite a lot of menu bar items, and a bunch of USB peripherals attached. Any suggestions at logs to look at? I've had a dig through Console, but couldn't see anything useful that coincided with the times of difficulties.

Do you know of any utility, terminal command, operation etc. that can instigate a TRIM 'on demand'? I'd like to keep the APFStimeout at 0 if possible, as rebooting is tedious otherwise.
 
I created a new "easy to install package" as per many requested (based on the official OpenCore). [The attached package updated to 0.8.0]
Hi all. Quick question as I have been out of the loop for awhile. I did have OC installed along with Big Sur & my system was running very stable. Then I decided to look at upgrading to Monterey but stupid me got distracted by the kids when I was editing my config.plist and ended up not being able to reboot. Long story short my back ups didn't work as expected and I now have a fresh install of Mojave 10.14.6 but no Opencore. So which OC version do I install? Am I correct in thinking I need to start around OC 0.6 to upgrade t Catalina then progressively upgrade each version of OS with a newer OC or do I just install OC 0.8 and then progressively upgrade OS? or can I skip any OS and jump ahead?

Many thanks.

You can install my latest OC 0.8.0 package directly.

Then, if you want to install Monterey, replace the config file by this one

and perform the config mod
 
Hi everyone,

I wonder if someone can help. I have Mac Pro 5.1 and recently I bought Radeon RX 6600 XT and replaced Radeon RX 580. While using RX 580 I was able to get a picture on three different monitors (well, in my case two monitors and one TV) and use it while doing video editing - the TV was used as a full-screen video display (in Davinci Resolve).

After I upgraded my video card the only way I can use this setup is this - Before turning on my Mac I need to unplug the HDMI cable and leave only two DP cables plugged in. After OSX is loaded I can plug the HDMI cable back in and then I have three monitors connected. If I don't do that I will only have one DP and one HDMI monitor recognised and connected.

Installed OSX is Monterey with Open Core 0.8.0 from #1314 without any modification
If I may ask, which 6600xt did you end up going with?

I believe the issue with the 3 monitor setup is to be edited in the .plist but my memory could be failing me. Maybe search for some threads regarding the issue! I’m sure someone else has had it before.

Ok, thanks, I will try to find it

I bought XFX Speedster SWFT210 because I have Sonnet M.2 4x4 PCIe card in slot 2 and I needed a card that will fit. XFX is only 4.1cm/1.61inch wide so there is enough space to put it in slot 1 and still have some air flowing under the Sonnet card. It is even thinner than my previous RX580 card
 
Hello,

First, thanks a lot for this "easy to install package". It's awesome to have the opportunity to install new Mac OS on a 5.1 !!

So last week I installed on a safe OS drive Big Sur 11.2.3 on my cMP 5.1 (see my signature) with the 0.8 package. Everything is OK ! But I wonder if it's possible and safe to install the last Big Sur OS (11.6.8) ?
(EDIT : I am new here maybe it's not the good place to ask this. Please ask me if it's not OK.
EDIT 2 : I don't know how to remove this post but I think it's useless here, I create a new one, sorry for the double post!)

I have not had any issues updating within 11.x using normal Apple Software update. If you go to Monterey, you have to jump through some hoops.

Yeah I have the same symptoms on 12.5 with Adobe apps and beach balling.
It kinda occurs after the wake from the sleep but I need to observe it further.

12.5/12.5.1 are a frequent source of headache for Mac admins, even with fully supported Macs. File sharing is the most frequent problem with supported Macs, with periodical disconnections or even failing completely after some days and needing a full restart of the Mac.

11.6.8 works a lot better from the Mac admin perspective, no headaches.

Interesting, on my Intel MBP 16 @ 12.5.1 everything runs smooth, no beach balls on Adobe apps.

EDIT: @tsialex After waking up this mbp I had very slow response from After Effects, it was so much annoying that couldn't continue work. I restared AE and had multiple crashes of this app. Can't load the project at all.I need restart just like with the cMP.
Apple broke something really bad in last updates of Monterey, I think I need go back to 12.3 and see how it will play.

And still more than one year of support.
 
Monterey has certainly been a greater than normal amount of hassle. Can add the 'volume hash mismatch' error to the list as well. Can't remember why I updated from Big Sur actually (I don't usually update until the summer following an OS release). Monterey will certainly be the last OS I'll run on this Mac (probably won't have much choice in that) - it will be good once the point releases stop, and we have a stable target to find fixes / workarounds for.
 
UPDATE Monterey 12.5, OC 0.8.0 Martin:
It seems that Adobe is here to blame with my issues.
After Effects 22.6.0 and 22.5.0 stability problems, frequent beach balls spinning, UI weirdness, Home Screen open project crashes. I've found that Windows, MacIntel and M1 users are also complaining.
After Effects 22.4.0 flawless, no crashes, everything works fast and stable.

Overall 12.5: cMP works great, stable, no KPs, everything is smooth and fluid.
Just a minor problem: Continuity stopped working with my iPad and my cMP do not see the MBP...
I wonder if full update to OC 0.8.3 would help?


EDIT: I updated BlueToolFixUp.kext from 2.6.1 to 2.6.3 and it works flawlessly :)

OpenCore 0.8.4 was released yesterday. An updates coming to your package @h9826790? :)
I won't be able to move into my new home until mid Oct. There is lack of computer for me to work in the temp home. So, my plan is to skip the OpenCore update until 0.8.6. Unless there are some urgent matter need to be address ASAP, then I will see if I can release another 0.8.0 config as quick fix.

If really need the latest OC to fix the issue, then I can still make one, but most likely will cost 1-2 weeks.

I understand. Take your time of course. :)

I've had a couple of issues where suddenly no video would play in macOS – YouTube videos would just spin and not start. Same for the intro ”movies” in Apple Arcade games.
Also one time I got a lot of beach balls in almost every app. A restart fixed both issues. Not sure what's going on, it's usually stable. Monterey 12.5.1 Something with my machine or any OpenCore related thingy or kext? I don't know.

Anyway, I could dig into moving to a new OC version myself, maybe… But don't really have the time nor energy at the moment.

Good luck on moving to your new home! :)
