Oldie but goldie: Use your iPhone Hotspot via USB for internet, assuming you got a decent data plan. Or since it's a desktop, get a WIFI extender connected to your ethernet port until that wifi driver issue is being sorted.

FYI, it runs fine before I changed GPU with radeon wx4150 and replace the logicboard. original logicboard and gpu is damaged. and now I only see Software Versions in System information (Wifi section). do you think it's hardware problem?

Hi @deeveedee! I feel sorry for you...
On my 27" iMac from late 2013, instead, maOS is still as fast and responsive as ever....
Maybe you need to wait a little longer for the caches to build up, for the System to settle, for Spotlight to recreate itself, for XProtect to scan the disks, etc. after which your Mac should become responsive again.

Have 2x iMac 14,2 (Kepler GPU) on Sequoia 15.3 + OCLP 2.2.0 and a few iMac 12,1 with Metal GPU (Kepler) upgrade on Sequoia also.

A lot of shader compiler jobs that eats performance after login (especially first time) which cause slowness or higher fan spin (with i7 CPUs) My guess is Kepler (older metal spec) related. Doesn't happen on iMac 12,2 + AMD Polaris GPU (2019 era) upgrade. Here is detailed study on iMac 12,1. Acvitity Monitor will show lots of shader compiler tasks on Kepler GPU based machines.

BTW, do you see a few random graphics glitches on the iMac 14,2? Seen a couple and usually just goes away by itself.

Safari, App Store seem to be fine. I don't use apple tv.
cheers!

The CPU does not have AVX, did you set the fix to startup then, because I don't see it being incorporated yet?

Usually an exclamation mark in the Wi-Fi icon points to issues with connecting to the existing Wi-Fi.

Do you have the same issue in trying to connect to your hotspot on your iPhone?

Did you ever check the system information/network/Wi-Fi?
Is the hardware recognised properly?

From what you’re saying, I’m assuming it’s an issue with the router you’ve got there. However you can’t exclude hardware compatibility issues after swapping so many internal components.

My wifi is ok. I think it's hardware issue. I don't know from the card or wifi slot or opencore. here's system information on wifi section. only Software version appears, no interface detected.

Just checking: The wifi card was swapped as well? Is it seated properly? How was the previous main logic board damaged? Same issue with a good known wifi card? Is compatibility given i.e. firmware up to date? Does the same card work in another iMac?

Just by looking at the questions, as some suggested here before an external wifi adapter seems to be the most economic solution to go for. If thats what you want.

I have 3 cards from another imac. I tried all of them and no luck. yes it seated properly with screw. previous logic board only fans running, 2 diagnostic led on. I can't fix it so I buy used board. I don't know about firmware, what firmware?

I use oclp 2.3n
Safari runs just fine, I would guess oclp includes the fix. Same with apple store.. it just works for me.

Hi, today I could smoothly updated my MBP15' Late 2013 11,3 from macOS 15.3 to 15.3.1 via macOSInstaller in USB memory, and after that rebooted, OCLP-2.0.2 downloaded MetallibSupportPkg(15.3.1 - 24D70) by Root Patching.
Thanks Developers !!

Hi @howardc64, my 14.2 iMac is with an i7 CPU and nVidia 780M graphics card with 4GB of VRAM, from the Kepler series and with Sequoia I have never had generic graphics artefacts.
However, what I described in my post, regarding the bug plaguing the Color Editing Tools in Preview, is still a graphics artifact related to the Kepler card. The histogram does not appear (there is only the box with the empty transparent background) and if you press the “Auto Levels” button or if you touch the two sliders at the ends the image disappears.
Conversely, in Pages this adjustment works normally.

I will sadly go back to Sonoma which worked 100% fine if the OCLP Developers cannot solve this Preview problem which is essential for me. So, perhaps, I might resign myself to accept the flaws I have mentioned other times, namely: the slowing down of Wi-Fi after several sleeps and the strange behaviour of transmitting YouTube videos from my iPhone to the Mac since I find it absurd that some videos work fine but the majority refuse to appear in the Mac… Mah… I would discard the hypothesis that it depends on the Kepler card and think more of a DRM problem which I cannot understand and solve, however. I am not a Developer...

(MacMini 6.2 Sequoia 15.3.1) Since upgrading to Sequoia 15.2, I have encountered a problem: I cannot access any websites that have a Cloudflare verification (are you a human?). I either get an endlessly spinning circle or simply an error if I need to check a checkbox. The same issue occurs when using the Orion browser (also WebKit). I held out a faint hope that this was a temporary bug and would be fixed, but unfortunately, the problem persisted in all subsequent beta versions. Meanwhile, Google Chrome and Firefox work without any issues.


What I have tried: I reset the router to factory settings, experimented with different DNS settings, disabled/uninstalled AdGuard, turned off/deleted all the few Safari extensions, tested both wired and Wi-Fi connections, toggled the firewall on and off, disabled "Prevent Cross-Site Tracking" and "Hide IP Address from Trackers" in the browser settings, and turned off "Limit IP Address Tracking" in system preferences—nothing helped.


I installed Sequoia 15.3 cleanly from a USB drive. I only patched it (OCLP 2.2.0) and did not change anything else. Still, nothing changed; the issue remained.


I reverted to 15.1.1 and Safari once again passes all Cloudflare checks with ease, unaffected by any DNS settings, AdGuard, firewall, or extensions.


I like Safari, but constantly switching between two browsers is nonsensical. Has anyone else encountered something similar or have any suggestions?

Smooth update from 15.3 to 15.3.1 on my trashcan... I noticed there wasn't any message from OCLP during the update download, I assumed it's because root patches are the same as 15.3... So I let the update install and then of course reapplied root patches (15.3). Working like a charm.

Yes, the newer Safari has issues as you've found. I believe 15.1.1 is the last OS before the changes that broke webgl and cloudflare, as least for my machine (MBP 9,1). I don't have any newer natively supported Mac to check if it's broken elsewhere.

Reverting to Safari 18.1.1 (for now) may be an option. See the Ventura conversation starting here.

EDIT: It appears that reverting Safari in Sequoia is not an option. See here.

Thanks a lot for the links! I'm reading them now, and it's all falling into place. It's good to know I'm not the only one dealing with this issue.

Thank you so so much to all the people that have allowed me to upgrade my 2017
13 inch MacBook Air with low specs to 15.3.1. You are the best.

Try this. If it works for you, can be added to login.

 

[houser]

Try this. If it works for you, can be added to login.

Safari Technology Preview might also be worth a shot for those who have not tried it. Typically has some later fixes that may or may not help.

Unfortunately, nothing has changed I don't know if it matters or not, but the same errors remain in the console. Thank you anyway for responding.

In my case, unfortunately, it didn't help. Thank you anyway

Probably not worth spending time on, but when attempting to run patches again today in OCLP I got:
"metallib already installed (15.3.1-24D70), skipping"
It does not matter I suppose but it looks like it was already there before today. Ah well.

On my MBP6,2, Sequoia is noticeably less responsive than Ventura and Sonoma. And 15.3 is a bit less responsive than earlier versions of Sequoia. I've accepted this as "normal" for my 2010 (15 year old) hardware.

You don’t have video/dynamic wallpapers on do you? The default video wallpaper brought my late 2015 iMac to a crawl, almost unusable. Once I’d set it to a completely static image and rebooted, Sequoia actually feels snappier to me that Ventura or Sonoma ever did, I love it.
