Isn't that RC6? Not that it matters much, just a boring matter.....

 

[MacMorrison]

Yes, it's a record 6th release for 15.7.8.

The last 2 RC updates were successful but seem to connect to wifi so use my phone as a hotspot

I got an idea of getting acceleration of 1 bit LLM on our good old Metal 2 HW so I asked GLM 5.2 if it is possible. It said yes.
If you are interested in this, look on whole post i sent it to AI section, thanks:

Can you post it here? I have found Discord to be rather an unpleasant site, no intention to go there at all.

Thanks for trying. Clicking on that does nothing, it is not a real link. Don't worry, someone will post a link when it becomes available, probably Adore as he is usually the first!

Just a crazy idea. Has anyone tried the Mr.Macintosh website for downloading MacOS resources?

Mr. Macintosh, is that you? 🤣

Many have used that site, one of the best resource points you can find in the Mac ecosphere.
It even has all of the Golden Gate beta full installers.
Unfortunately, it doesn't have the Sequoia RCs or betas.

updated and running well.

 

[rehkram]

Both Macs in my sig up & running on 15.7.8 (24G822) RC 6

So that's an rMBP10,1 2012 (w/OCLP 2.5.0n), and a MacMini8,1 2018 (no OCLP) w/the T2 chip, still working fine under Sequoia.

 

[macsba]

Mr. Macintosh, is that you? 🤣

Nope, just a user of his services.

 

[basslik]

Wow, JUST UPDATED.

Imagine this. running the latest Pro Tools 2026.4.1, and still tracking on my 2007 Digi003.

Thank you ALL!
Thank you OCLPView attachment 2646811

RC6 FOR TWO DAYS, RUNS SMOOTH.
