Hi everyone,

I created a USB installer using Apple’s official InstallAssistant.pkg, and used it to perform a clean installation (not an upgrade or Time Machine restore) of macOS Tahoe 26 on an NVMe SSD. With Beta 1, everything worked fine — I was able to install and boot into the system successfully.

 

However, starting from Beta 2 (currently on Beta 3), I consistently run into an issue where the installer gets stuck at "About 17 minutes remaining" and never proceeds.

 

Interestingly, if I install macOS Tahoe on any SATA SSD, the installation completes without any issues.

 

My setup:
- CPU: Intel i7-10700K
- Motherboard: GIGABYTE Z490 VISION G
- RAM: 32GB x2 DDR4-3600
- NVMe SSDs tested: Samsung 970 EVO / WD PC SN730
- OpenCore: 1.0.5 with SMBIOS: iMac20,1

 

This configuration works perfectly from macOS Big Sur 11 through Sequoia 15, as well as macOS Tahoe 26 Beta 1.

 

I’ve tried various combinations to troubleshoot the issue, including:
- Switching between different versions of OpenCore, Lilu, and WhateverGreen
- Install on the NVMe SSD via connected with USB Type-C adapter
- Changing SMBIOS to MacPro7,1
- Installing with and without NVMeFix.kext

 

Unfortunately, the installer still freezes at "About 17 minutes remaining" every time when using an NVMe SSD.

 

As a workaround, I currently install the macOS Tahoe 26 Beta 2/3 on a SATA SSD, then use Disk Utility to restore the installation back to the NVMe SSD, which allows me to bypass the installation freeze in Beta 2 and 3.

 

Is there a proper fix for this issue? Any advice or insights would be greatly appreciated.

 

I've attached screenshots of the issue and my config.plist for reference.

 

Thanks in advance!

Edit: 

Apologies for not explaining things clearly in my original post. Here are some additional details:

  • I have already updated Lilu, AppleALC, WhateverGreen, VirtualSMC, SMCProcessor, and SMCSuperIO to their latest Release versions. Please disregard the version comments in Kernel -> Add -> XXX.kext/Comment.

  • I have set the MaxKernel version to 24.99.99 for all BCM94360 Wi-Fi–related kexts:
    IOSkywalkFamily, IO80211FamilyLegacy, AirPortBrcmNIC, AMFIPass,
    as well as the Kernel -> Block -> com.apple.iokit.IOSkywalkFamily entry.

  • WhateverGreen and AppleIGC also have their MaxKernel set to 24.99.99.

Theoretically, setting MaxKernel = 24.99.99 should prevent these kexts from being loaded on macOS Tahoe (Darwin >= 25.0.0). Even with the boot-args including -lilubetaall, these kexts should not be active.

 

I will also try completely removing the related kexts from Kernel -> Add later to see if that makes any difference.

大家好，

我使用苹果官方的 InstallAssistant.pkg 创建了一个 USB 安装程序，并用它在一块 NVMe SSD 上全新安装（并非升级或 Time Machine 还原）了 macOS Tahoe 26。在 Beta 1 版本中，一切运行正常——我能够成功安装并启动系统。

 

然而，从 Beta 2（目前是 Beta 3）开始，我不断遇到一个问题，安装程序卡在“剩余约 17 分钟”并且无法继续。

 

有趣的是，如果我在任何 SATA SSD 上安装 macOS Tahoe，安装就会顺利完成。

 

我的配置：
- CPU：Intel i7-10700K
- 主板：GIGABYTE Z490 VISION G
- 内存：32GB x2 DDR4-3600
- 测试的 NVMe SSD：Samsung 970 EVO / WD PC SN730
- OpenCore：1.0.5 带 SMBIOS：iMac20,1

 

此配置在 macOS Big Sur 11 至 Sequoia 15 以及 macOS Tahoe 26 Beta 1 中均能完美运行。

 

我尝试了各种组合来解决问题，包括：
- 在 OpenCore、Lilu 和 WhateverGreen 的不同版本之间切换
- 通过连接 USB Type-C 适配器安装在 NVMe SSD 上
- 将 SMBIOS 更改为 MacPro7,1
- 使用和不使用 NVMeFix.kext 安装

 

不幸的是，每次使用 NVMe SSD 时，安装程序仍然会在“剩余约 17 分钟”处冻结。

 

作为一种解决方法，我目前在 SATA SSD 上安装 macOS Tahoe 26 Beta 2/3，然后使用磁盘工具将安装恢复到 NVMe SSD，这使我能够绕过 Beta 2 和 3 中的安装冻结。

 

这个问题有合适的解决方案吗？如有任何建议或见解，我们将不胜感激。

 

我已附上该问题的屏幕截图和我的 config.plist 以供参考。

 

提前致谢！

It will automatically restart after 1-3 hours, you just need to wait. This issue has been widely occurring since Beta2

First, the OpenCore EFI (kext, driver, boot, etc.) should be updated. Wi-Fi/BT kexts should not be used in the installation.

Note: This may be personal, but I'd be suspicious if I have a Samsung NVMe. Especially the 970 EVO. I've seen it freeze a few times when used with another NVMe. Even though Samsung has released firmware for this series, it's still available.

Thank you very much for your helpful reply. I followed your advice and waited — after about 50 minutes, the installation process resumed and the system was finally installed. I'm really glad to have the installation completed. I truly appreciate you taking the time to share this information — it made a big difference.

Thanks again!

Uauuuu it's relaxing reading the difficulties of others when we, in this case, me have a real Mac... LOL

But I'm glad that the things are hard but are solved one at a time.

Regards to all

Wow 50 minutes!!!

Personally I would have given up, at the exact stage my own was 5 minutes max.

 

Still, happy to hear you were patient enough to see it through.

Enjoy. :thumbsup_anim:

Like you I get impatient but sometimes if I reboot back into the installer it doesn't hang the 2nd or 3rd time. This worked for me in beta 1, beta 2 there was no wait at all - took about 5 minutes all up.

Working with Mediatek Driver High-performance 802.11n Wifi USB Adapter

D-LinkUtility-Package

A quick OT guys..

hi @chris1111 

A suggestion...

It would be better to rename your all your wifi packages. currently, Its too universal which makes it difficult for others to identify which is which for.

 

D-LinkUtility-Package = Ralink/Mediatek

Wireless-USB-OC-Big-Sur-Adapter = Realtek

And so on...

 

Now back to Topic 👍

Thanks @LockDown its already specify for the 3 Realtek utility

I add the same for the Mediatek utility done!

Note; D-Link and Ralink was the first builder of the utility associate with Mediatek

this is why the name is D-LinkUtility-Package

IOS 26 public beta will be released in the coming week.

 

macOS Tahoe perhaps will skip Beta5 and subsequent Dev Beta versions

Apple pulled the macOS Tahoe public beta shortly after this article was published.

And will macOS Tahoe Beta 4 be available today?

Theoretically, it should have been pushed, but Chinese Mainland has not received information about Beta4
