Are there any known issues with iCloud drive in Sequoia, or with patched macs? I couldn't get Time machine to backup until I turned off iCloud drive after the upgrade. Something about files syncing. I don't specifically sync any files to iCloud though, just whatever the apps share automatically. The rest of iCloud seems to be OK.

I Use iCloud Drive and Time Machine and do sync files but haven’t experienced a issue on my patched MacBook Pro and Sequoia ( i think it’s one of the greatest things about OCLP that everything syncs like it should on a “newer system” and wonder if it would still sync perfectly on a old MacOS e.g password app and so on.

I found the problem I had on the Apple support communities with a supported mac, and the solution is to do what I've done. Disable drive, make the backup and when done going to re-enable drive. According to the post that solves the problem.
 
2.3.2 was released several days ago? How is it?
Is it worth the potential hassle to upgrade from 2.2? Everything on 2.2 works fine for me, so I was thinking about not updated for like at least 1 year.

If you are updating macOS to 15.4 or higher then you should definitely update OCLP first. 2.3 also came with some other nice to have features like graphics optimizations.

Not aware of the graphics optimizations. Where are they, and what do they do, and are they only for non-metal, or all macs? My late 2015 27" iMac is both Metal and AVX2 compatible.

Have an iMac 2012 and everything worked well with v2.2. Then updated to macOS 15.4,and updated to the lastest Open Core Patcher 2.3.2 and started to have issues. Mac started to freeze up on occasion. I have been working three days to fix and reinstall. Should have stayed on macOS 15.3 and v2.2.

No complaints…love OpenCore Patcher and appreciate all of the developers hard work for us! This is just part of the game to keep good old systems current.

With Open Core Patcher, my intel old system works BETTER than the new M-series Mac’s for the configuration and hardware I using, so MUCH appreciation to the developers of Open Core Patcher, but reporting the issue.

Don’t know in detail, but the release notes mention two graphical improvements:
  • Resolve Broadwell widget rendering on macOS Sequoia
  • Resolve some T1 communication issues on macOS Sequoia
  • Resolve some non-Metal graphical issues on several OSes
Doesn’t sound like your iMac specifically is affected though.

There’s no guarantee things will work well on unsupported hardware. Many are having no issues with macOS 15.4, though as you are finding you’re mileage may vary. But OCLP 2.3 is specifically targeted at improving compatibility with 15.4, which is why I mentioned that in my comment.

Yeah, I am familiar with those changes, just wondered if I had missed something. Anyway the Logitech GHub error seems to only happen on slower than normal logins, otherwise is fine. Since I can't use 3D acceleration with VMware Fusion under non natively supported versions of macOS, I've uninstalled it and will keep it available for older supported installs. Also seems like Broadcom has killed it. So for Linux, will just keep my dual boot.

Hi everyone,

I just downloaded the latest update of WhatsApp Desktop from the Mac App Store and was delighted to find that the program starts and works again on my MacPro3,1!

This can mean two things: The program no longer needs AVX2 compatibility or it was simply another bug, now fixed, that was preventing the program from launching.

Anyone who had the same problems on their vintage Macs should give the update a try!
 
I have tried 15.5 b1 on an external disk, got 2 problems :

- Internal disk doesn’t mount on desktop
- Disk Utility does not respond.
- Even diskutil list command doesn’t respond in Terminal.

I use the Enpass app for my passwords. Since the update to macOS 15.4, I can no longer unlock a vault with Touch ID or an Apple Watch on my MacBookPro14,2. Because it works perfectly on my MacPro3,1, which is still running Sonoma due to the dual socket issue, I assume that it could be a bug in macOS 15.4 or OCLP 2.3.2 in connection with this computer. As is known, there have been recent adjustments for T1 in OCLP. Addendum: Touch ID otherwise works on this MacBookPro14,2 ...
 
macOS 15.5b1 appears to use less RAM than 15.4. 👀
How did you measure that? I just did a quick, very unscientific check on my MacMini8,1 (supported, so it doesn't need OCLP) and don't see enough of a difference to make a determination. The following screenshots are captured in Activity Monitor after allowing macOS to achieve steady state with no apps running, no login items enabled.

How to disable Apple Intelligence for the Mac in MacOS 15.4 and up.

Apple Intelligence requires that Mac and Siri are set to the same language.:apple:

• Set Mac to English-US and Siri to English-UK or any other language. Reboot

Thanks to Macintouch for this👏

What is the benefit gained by disabling AI.
 
How to disable Apple Intelligence for the Mac in MacOS 15.4 and up.
I was under the impression that Apple AI unambiguously requires Apple Silicon.
Meaning all OCLP Macs that run OCLP do not need to disable anything if you don't want AI as it will not run on Intel.
Is there new info that says otherwise?
TBH, Intel is an advantage to old guys like me who will not touch AI with a ten foot pole ;)

I installed Sequoia 15.4 with the latest OCLP on my Macbook Pro 2017 15" touchbar. After insisting on Ventura for a while, I decided to change.

It's incredible. It looks like an official system. I didn't even need to perform a post install. The temperature and fan are all fine, except for the passwords app. I installed it over the top to preserve the touch ID and touchbar. I disabled all updates. Now I can just enjoy and take advantage of the updated features of the apps, with the system at the same level as iOS 18.4 and tvOS 18.4.

Or just turn it off in Settings...

As already mentioned, this isn't relevant for any Mac requiring OCLP to install Sequoia anyway since Intel Macs don't support Apple Intelligence.
 
Very smooth upgrade from Sequoia 15.4 -> 15.5 Beta (24F5042g) on my HackBookPro6,2 (2010 non-metal Nvidia Tesla). Applying post-install patches with OCLP 2.3.2. Very impressed by how well this old hack continues to perform. OCLP Devs, thank you for preserving the fun in tinkering with old hardware like this! Still hoping for another year of Intel support so that the fun doesn't end.

I upgraded a copy of my Monterey SSD to Sequoia 15.4 on both my cMP 5,1 and my cMP 4,1>5,1. Everything seemed to go well.

I could log in, although with no Bluetooth and the wrong colors on the screen, which I expected. I ran the post-install patches and rebooted. After the reboot, the login window appeared, but after inputting the login password, the screen went black and then back to the login screen. I am using the correct password, but each time I enter the password after applying the post=install patches, it loops around to the login screen. It is doing the same on both my cMP 5,1s

Without being able to log in, I can't see what I can try to resolve this.

I still have Monterey working and have SSDs with Mojave and ElCapitan installed.

Any suggestions would be welcome.
 
In your place, @OldMacPro2 and @David403, I would try reinstalling everything from scratch, using the USB installation stick created with OCLP, remembering to install OCLP when finished.
Then reboot the Mac and at startup, while holding down the Option key, install EFIBoot from the stick, then continue with the recovery utilities, format the entire disk, and try installing again.

Warning. If you create the USB stick with another Mac, you MUST indicate the Mac on which you want to install Sequoia from the list of all OCLP-compatible Macs.

I wish someone would give you a better suggestion than mine and faster…
The thing is that just this morning, reading the latest article on "The Eclectic Light Company" blog, I saw that the macOS 15.4 installer creates several problems in some cases.

Toward the end, I read that Apple has made changes to the installer and that, although this is known to cause problems for M1 Macs, it could interfere with unsupported Macs as well. And by the way, this is not the first time Apple has caused problems with new System updates....

So, in your place, I would choose to download and install macOS 15.3.2 to be on the safe side.

REFLECTIONS AND CONCLUSIONS
(Obviously from my point of view that I do not want to impose on anyone...)

After all, Sequoia 15.4 only introduces mainly AI changes dedicated only to Apple Silicon models... Another factor that causes burdening to Intel Macs (but also of M-series Macs) also because we all act as lab rats for the benefit of Apple which is far, far behind with AI, with the new Siri, etc. And so, in trying to gain time quickly, it will inevitably cause problems, depending on the Macs on which we will be doing the installations.

I conclude, even for the above reflection, that I am now 99% in my decision to go back to Sonoma. In Sonoma Apple does not have to experiment with anything and the System has proven to be stable and ultimate for Intel Macs and, of course, especially for all of us who use Intel Macs and OCLPs.
Why, then, want to tempt fate for nothing in return but various problems lurking?....
 
... we all act as lab rats for the benefit of Apple which is far, far behind with AI...
OT, but I can't resist the temptation to opine... I'm learning PyTorch for neural networks / deep learning. It does feel (to me) like Apple made a product management mistake by "closing" their graphics architecture. I'm planning to purchase my first NVidia GPU in more than 7 years. I'll install the GPU in a non-Apple system to accelerate tensor calculations. The system will dual-boot Linux and Windows.

I wonder if we'll see future MacPros with 3rd party dGPUs.

Have you tried resetting SMC<NVAM, restarting in safe mode, then reverting patches and installing the latest nightly, then installing 15.5, then repatching. My Imac is running better than ever before with n and 15.5, before that I had various problems with 15.4b's.
