Testing Big Sur beta 11 installation on MacBook Air (13-inch, Early 2015)

I'm going to try to install "Big Sur" on an old macbook air and see what happens.

Just now i got this error:

I had to login developer.apple.com and download .dmg again.
I installed that .pkg and restart upgrade.
Now i see this:

Ok now i had to delete almost everything because this macbook air has a 128gb. ssd:

Now it is installing:

And now it says almost 4 hours. I hope i don't get a fatal error:

As you can see it is now more than 6 hours:

Maybe this is because im upgrading from Mojave not Catalina. I didn't install Catalina it was very buggy. But now i have to upgrade because i have a mac app on the store that needs to be "big sur" ready asap.

Now a few hours later im looking at this:

At this point i just don't care anymore. Im gonna leave this open and go to sleep. I will see what happens when i wake up.

I have just clicked cancel.

It was at 7 hours mark and i got mad.

So as you can see it is almost impossible to install "Big Sur" beta 11 on a MacBook Air (13-inch, Early 2015). So i hope they are going to fix their big release later.

Final Thoughts

I think it is too much of a risk at this point. I felt like installing a Red Hat linux to a pentium 3 machine. I also did that years ago and it took me 5 hours to finish with 8 CDs and no internet connection. But this Big Sur beta 11 installation couldn't even finish after 7 hours.

This is pretty much par for the course with Apple updates, and it's why people are so reluctant to do them. My current job strongly discourages anyone from updating MacOS because we're all working remotely and it's that much harder for someone to troubleshoot.

A fun game I like playing is counting the number of different widget styles the update progresses through, such as background colours, progress bars, and so on.

The best bit is when Macbooks restart but don't turn the screen on and you have literally no way of knowing whether they've crashed or are just slow, because Apple don't want you to be exposed to scary things like power indicator lights.
