Club 11

Snowlover said:
I just ordered a 2011 (4gb, 128gb) 11 inch air from Ebay with charger for $45. Should arrive in a week. I was wondering if it is possible to install Snow leopard on it from a bootable clone I still have made off a 2010 mini ( I think). If not, I'll just go with mountain lion. Thanks
Looking forward to enjoying club 11 membership. 🥳

Update on the "new" 2011 11 inch air:
It arrived in good physical condition, but wouldn't power on, and seller forgot to pack the magsafe 1 charger (I only have a spare ms2).

So, he sends one out immediately (in pristine condition), and 2 days later, I charge it, boot off a mountain lion clone ( it was sold as missing an os) and try to clone back to the internal ssd. No go.
Run drivedx and find ssd was dead, not missing os.
Contact seller again and he refunds me $20 to replace the ssd.

Sooo, I bought a 256gb apple used ssd off ebay for $30, checked it with drivedx, Installed it and cloned mountain lion onto it. All good now , right?
No. I couldn't get it to connect with my wifi network no matter how many fixes I tried.

I finally decided to try high sierra instead, as I also have a backup clone of it. Took forever to clone off a spinner over usb2, but works like a charm. No wifi issues at all, and I think I'm glad it worked out this way in the end. 🙂 All in all ended with a nice 11 inch air with double the ssd for only $10 more, $55 total.

"Club 11 welcomes its prospective members :)

Admission to Club 11 is in ownership of a 11.6" MacBook Air belonging to the 2010 (because it's a Core 2 Duo machine) or 2011 (because it doesn't officially run a still-supported version of macOS) generation."

So I am assuming an invitation is not required.
Anyway, welcome to the club!

has anyone booted an older OSX like Snow leopard on a macbook air 2010-11
using an exteral HD?
im usng a bitsjour enclosuer that wort or is trying to read a 68GB of snow leopard as that did not show up as an option while pressing the "option key". My MBA is running Mojave and the drive works as that read another blade of time machine as might reformat that 128GB to Mt Lion.
My plan is to use an external of snow leo to running a scanneras well as CS4 mainly photoshop on finished art work.
thanks in advance!

Tried Snow leopard from external clone on a 2011 with no os/bad ssd, booted to a blank screen. Didn't try after replacing ssd. Ended up with High sierra, maybe I will try booting Snow leopard clone again when I have time.

The problem you are having may be that the apfs formatted internal drive doesn't recognize hfs+ .

How does Mojave run on a 2010 air?
 
Snow leopard bootable backup does show as option , internal ssd formatted to apfs running High sierra. Still just boots to black screen.

I don't think SL, or any other OS prior to HS, supports apfs.

True.
Was trying to boot from bootable clone of Snow leopard (to see if it might be possible to use it on 2011 air), and to see if having apfs formatted internal prevents one from seeing older os formatted hfs+.
I think I have it backwards , older hfs+ formatted os will not see apfs formatted bootable clone in boot options?

After the older OS has booted it cannot see the apfs partitions or disks. And as the SL does not support apfs I think you cannot boot a SL cloned into apfs disk.

I very rarely set the boot disk from inside the OS. I usually use the alt pressed boot option to get the boot menu and make my choice there. This allows choosing between various MacOS and Linux versions easily which might not be visible inside the OS at all.

I think my OS installation disk has mixed hfs+ and apfs bootable partitions and they all are visible in the initial boot menu (boot with alt pressed) as no OS has been booted at that time. A bootrom upgrade might be necessary to make the apfs visible at that point in older machine made prior HS? I believe the bootrom is upgraded when HS is installed to that machine and after that one can go back to older OS. One might need an original Apple drive to do this, the machines can be picky about it. Rarely a problem with MBAs though.

When I had a multi-boot setup with Linux and macOS on my 2010 MBA, rEFind worked well for me in this regard.

Hat tip to @Hughmac for that one. :)

SL wasn't cloned into apfs disk, was an external bootable clone on hfs+ . Nor did I set boot disc from inside os, which I pretty much never do. Like you I use the option key while booting to choose. I guess I wasn't clear on that.

When I attached a different external drive (apfs formatted) and booted with option/alt, it showed the High sierra and Mojave clones, but only the data part of the Monterey clone.
Edit: on a 2014 mac mini (that I bought with Monterey installed but replaced with windows 11), the same external drive booted with alt/option does show the Monterey clone.

what does "cloned" really mean?
Click to expand...
As I am using the term , it is an exact copy of a drive (or partition) that is bootable. I use carbon copy cloner to make clones of mac operating systems I want to save for potential reuse on another machine or when harddrive/ssd fails.
I have found that old installers I have kept can be unreliable .
