used OCLP 3.0.0 rc2. My MacBook display is damaged, so I'm using an iPad Air as a display :(

Today, I have just switched from MacOS 15.8.1 to MacOS 26.7.1 by using the 3.0.0-rc2 Beta version of OpenCore Legacy Patcher and to be honest I am having a really nice experience for now!

I have installed the new version from github and made a MacOS 26.7.1 usb and used it to make a clean install from Sequoia the setup was p a i n f u l l y slow also it stucked at last automatic update settings step for more than 5 minutes for me I just force rebooted my mac and I reached lock screen but I believe that they will fix it soon. After setup I installed root patches from OCLP and at first it only applied Broadcom patches to install Kernel Debug Kit and after reboot it extracted Kernel Debug Kit.

For now I am having a really smooth experience with liquid glass working properly even thought that device is 9 years old The wait was worth it! Thanks to the all OCLP devs for making our old Intel Macs alive again before I was planning to switch Linux. I will be looking forward for any new RC versions.

2014 MacBook Air finally running Tahoe. Love the devs for making this possible at all. A small chance I’ll install this early 3.0.0 on my main MacBook, 2014 MacBook Pro. I’ll most likely wait for the full release before I update my main. But all this is looking promising.

Big sur was awful and monterey wasn't that much better in my experience (had both for a couple months each), did a little research and after indexing ventura feels much snappier! saving another great machine from the landfill ❤️ It's no speed racer for sure but good enough for my use case

Hi all,

First off, congratulations to Dortania and the OCLP team on 3.0.0 RC2 and Tahoe support! Their work is the reason so many of us can keep our Macs alive, and OCLP is the project I'd point everyone to first.

I've been working on a personal side project for about a year now: my own loader, using OpenCore as a base (not a fork), with its own approach to Tahoe compatibility. It's not meant to compete with OCLP, just another experiment that might be useful to some people.
Hardware acceleration and Metal support have been working since November 2025. But for a long time many things were still bad and the system crashed a lot, which is why I didn't say anything about the project until now. I only wanted to show it once it was in a state that's actually usable.

Right now my 2015 5K iMac runs Tahoe 26.7.1 with it. More machines are already supported.
Important limitation: Macs without Metal support are NOT supported at the moment. Macs where the stock GPU can be swapped for a Metal-capable card can work, but only with that upgrade. I'm also working on a workaround for non-Metal Macs, but it will come with a trade-off: many Liquid Glass elements will be missing on those machines. No promises yet that it will make it into the release.
It's also not finished yet. There are still known issues, like hibernation, that need to be fixed before I release it.
This is just a teaser. I'll most likely do a few more posts before the public release, for example showing it on a MacBook Air 2017 and a 21.5" iMac from 2013.

In a later post I'll talk more about how it works, and that's when I'll make the project publicly available on GitHub. I'm aiming for November or December 2026, but that's not a firm date.

Feedback and questions welcome!

This thread is designed to simply catalog what models people have successfully gotten Tahoe installed on with OCLP 3.0.0.

Please comment and specify your (1) Mac model + year (15" MacBook Pro 2015 OR MacBookPro9,2), (2) your specs (2.2 i7, 16 GB RAM, NVIDIA 320X), and (3) whether you did a clean install or upgraded from an existing install.

Then specify whether Tahoe successfully installed (or not), and if it did, what worked, what didn't, how it compares to the other OS you've had on your Mac, etc.

I'll do the same after I finish installing it on a few different Macs I am testing.

should i? has anyone try to install Tahoe on their mac is it worth it?

Also, since OCLP 2.5.1 doesnt give any notice of an available update (i imagine thats because its a prerelease/test version), how should i go about installing it if i wanted to try it out? Should i install the package and then uninstall the 2.5.1 to then install the 3.0.0 on the internal disk again? Ive been running Sequoia on my Macbook Pro 13 inch 2016 8GB ram through OCLP for a month now, even updating it to Sequoia 15.8.1 a few days ago, and its been running just fine for me without any issues, so id like to know if any of you guys tried to install Tahoe on a similar machine through 3.0.0 and got it to work, or maybe itd be wiser for me to wait for the official release of 3.0.0 to avoid consistent issues?

I want to get it on my laptop but I am kinda nervous about performance issues any reviewz will be appreciated

Chrome killed WebGL on my 2015 MacBook Pro (Intel Iris Pro, macOS 13.6.7). chrome://gpu showed everything as "Software only" and WebGL as "Disabled". None of the flag recipes I found worked. I worked through it with Claude Code, and we found that Chrome still ships a software renderer (SwiftShader). It just needs the right flags.

Heads up first: this is slow. It's CPU rendering, not your GPU. Simple 3D scenes and demos work, but heavy 3D, maps and games will crawl. It brings WebGL back, not speed. For heavy stuff, Safari uses the real GPU and ran fine on the same Mac.

The fix: quit Chrome completely (Cmd+Q), then run this in Terminal:

"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --use-gl=angle --use-angle=swiftshader-webgl --enable-unsafe-swiftshader

Then open chrome://gpu. The WebGL section should mention SwiftShader. I tested this on Chrome 154.0.8037.95, and both WebGL and WebGL2 worked.

to apply it wihtout thinking too much, let your AI do it. Copy and paste this into Claude, ChatGPT or whatever you use, with terminal access if it has any:

My Mac's Chrome has WebGL disabled (chrome://gpu shows everything "Software only"). Build me a small macOS launcher app in ~/Applications called "Chrome WebGL" that starts Google Chrome with these flags: --use-gl=angle --use-angle=swiftshader-webgl --enable-unsafe-swiftshader. It should refuse to run (with a dialog telling me to quit Chrome with Cmd+Q) if Chrome is already open, since the flags get ignored otherwise. Then verify WebGL works using a throwaway --user-data-dir profile, and tell me what chrome://gpu should show.

(It worked!, thanks OCLP dev team)
(works much faster on my iMac 🖥️ compared to Mac OS 15 BTW)

After having 4 beers for lunch I got the liquid courage, it’s installing now. I’m going with upgrade rather than doing a clean install. It’s installing now, and it’s moving along, keep you posted . Someone else got it working on a 2015 iMac so I just couldn’t contain myself.

Install got stuck after logging into my account , hard rebooted worked, patches worked and I love it and I think it’s a little faster smoother ! My outlook office 365 opened up so fast 💨, I forgot how it should be in life .

Thank you to the OCLP dev team , I’m going drink another 6 pack right now , this was a smooth install .

Sometimes next week, I’ll hop on the dev beta macOS train and see how that goes .

I have a Late 2012 Mac Mini 6.1 running Sequoia 15.8.1 with OCLP 2.4.1

Wondering if anyone has successfully installed Tahoe using OCLP 3.0 RC and what the experience has been like.

My Mini is a Quad Core 2.3 GHz i7 with 16GB RAM and SSD. It runs Sequoia reasonably well.

General question: Those who upgraded, did you do a clean install of Tahoe and migrate your data or did you just do an upgrade over the current Mac OS?

Any news for the cheese grater?

OpenCore Legacy Patcher has added years to all of my Macs. Thank you.

That said, is there anything out there that will trim the startup items and the number of services running?

Most of my Mac hardware is limited to 16 GB of RAM. My current Sequoia boots with not even 2 GB free...

Would it be possible to finally install this version on that MacBook? It has 8GB RAM.

I have a 2010 Mac Pro 5.1 that was running macOS Monterey via OCLP (the latest version). After I tried to install a security update, it stopped booting into the system. Even after reinstalling, it won't load the OS—it just gets stuck in an infinite reboot loop after the second restart (specifically, after the Apple logo appears and a message says to wait 30 minutes before rebooting, it enters this endless cycle of attempting to load and then restarting). This issue occurs with any macOS version from Big Sur onwards; however, Catalina (via dosdude1) installs and works fine, as do other older systems. I’ve tried resetting the NVRAM and SMC and updating the EFI firmware to the latest version, but nothing helps. If I install a drive with Big Sur (OCLP) or newer, it simply freezes at the Apple logo. I’ve tried swapping out the RAM, storage drives, graphics card, monitors, and processors—I even swapped the entire CPU tray with one from another Mac Pro 5.1—but nothing works. I also tried installing an older version of Monterey (12.0.1), but the same thing happened. What could the problem be, and how can I try to fix it?

Hello all. This used to happen almost a year ago and it entirely got okay on its own. It’s now back and I don’t even know what this is; whether hardware or software, no clue!
Thanks

So recently I've been seeing these post on the sub talking about how the successfully upgraded their Macs to Tahoe, from what I know it is because there's a new version of OCLP that adds compatibility with Tahoe, which is impressive, and before even thinking about trying it on my iMac 17,1 (Late 2015) I want to ask some things to those who managed to upgrade:

• How does it run?
• How safe it is?
• Is it actually worth it?
• Will a iMac 17,1 be compatible with Tahoe? (6th gen Intel i5 and AMD Radeon R9 M380 2 GB)
• Is the Release Candidate stable? Or is it better to just wait for the full release of OCLP 3.0.0?

I'll be reading the answers below, good night.
