The requested version of macOS is not available catalina

Same issue, MacBookAir6,2.

Same problem here, late 2017 imac, "Requested version of MacOS is not available"

Finally a solution.. Ty!! the only downside is that the version is the Beta... but I am in Catalina :)

I tried the same thing but I got the same result. It told me it wasn't available...

This is the only thing that worked for me. Thanks!!

Thank you, it worked.

This worked for me!!! Thanks mate!

Thanks! 😎😎😎

Hi,

After try it, it look like it works, but, after some % (511,1 MB of 8,13 GB) of installation, it fail again with "The Request time out" error message.

Any idea?

Thanks a lot !!!!

It works!!!!! Thanks!!!

I have same issue. can someone help pls ?

I tried both App Store and through System Preferences... same result: Catalina update cannot be found.

I am running MacOS Mojave on a 2013 MacBook Pro

It worked for me. thanks a lot!

i would advise you not to try.

Catalina creates nightmare. I am still trying to get mine sorted out without having to pay £600!

Hey,

Same problem for me, and I cannot Update to the release one.

I would like update my mac but no as a Clean Installation. I would like to get it as usual, just updating from macOS Mojave. Of course no to Beta version.

Does anyone solve it as I mentioned?

Thanks a lot
