macOS Tahoe update does nothing?...

[Matin]

I'm currently trying to update my Sequoia Hackintosh to Tahoe Beta. I downloaded the update through the Settings app, and I found the installer in Launchpad. The installation runs, restarts the system, and appears to complete the update process. However, when I restart, it still shows Sequoia. Ouch!

I also needed to change my device name from "2019" to "2020 iMac" to get the update, but my CPU is an i7-7700. Could this be causing the issue?

Additionally, I encountered an installation error:
"AHCI deviceWithError 0, errCode = 0xe0030005."

Thanks for your help!
