I’m getting error during Reinstall OS X Installation on MacBook Air 2010

I was able to bypass it by creating a bootable usb drive containing the OSX I needed. I followed the steps listed here:

Create a bootable installer - Apple Support (CA)

unfortunately you’ll probably need another Mac but if you follow the steps closely, you may be able to get it to work as well.

After a nummerous tries, i found the solution via a Question on 'Stack Exchange'. I do love that forum so much.

There is more to it then just one hint . . . . .

There are multiple problems to overcome, read this whole threath.

Source of the problem

Apple does not approve the El Capitan certificate anymore.

Solution

I have found multiple methodes for USB creations and downloads for the El Capitan installation via a browser somewhere ( sorry i forgot where). The only USB download one which worked for me is the 'El Capitan.img'. Dubble click on the image and continue in the terminal from there.

The Apple instructions to make a bootable usb stick also did not work for me. For the usb creation method that worked for me read here: https://www.lewan.com/blog/2012/02/10/making-a-bootable-usb-stick-on-an-apple-mac-os-x-from-an-iso.

The second problem to solve is to put the date of the Mac back to somewhere in 2017. Before the El Capitan installation starts, choose terminal and set the date back to 2017, command example: date 0115124517. Close the terminal and do not forget to disable Wifi.

Then install the OS, the install will now succeed (if there is no other hardware problem).

It is in Apple interest to post comprehensive and clearer instructions. I could not find those at the Apple forums quick enough.

Good luck everyone!

Boot Recovery with Option-Command-R, and try installing the newest supported for the Mac involved. Not the oldest. Don’t try for the oldest when starting out.See if that newest-supported version is accessible and works.

If that does not work, find another Mac that can download the older version directly, build a bootable installer there, and boot that. Or, well, try.

Versions of macOS older than OS X 10.11 can be used to create bootable installers, but those older versions don’t have the Apple-provided installer creation tool. Web search for details on creating those.

Older versions are usually an ongoing hassle. Including when trying to connect to newer websites and services that are increasingly requiring modern network security.

If requesting the most recent version of macOS supported for the particular Mac does not work via Recovery (⌥⌘R at power-up), then download and build a bootable installer on another Mac that can also run whatever older macOS version you're looking for, and boot and use that bootable installer to boot this old Mac.

It's been linked up-thread, but here it is again: Create a bootable installer - Apple Support

Recovery on older Macs was not good at that ⌥⌘R chord, and would get the oldest supported version for the Mac—they'd switch ⌥⌘R to ⌘R, or the user would enter ⌘R. If it's that oldest macOS version that is is getting the 403 error here, then you'll need to request a different macOS version for recovery with ⌥⌘R (where that works) or by using a different Mac and a bootable installer.

I have the same 2009 iMac, El Capitan and wiped it but now can’t reinstall OS as im getting error message forbidden. ANY SOLUTION?

Thanks jpgmfrombeverwijk ! I have exactly the same error, trying to reinstall El Capitan from a USB stick on an old iMac from late 2009 after changing the hard drive.

I can set the date to early 2017 or whatever (I've tried several dates :)) in the installation process (open a terminal and set the date). But if I do that, I get an error before signing.

The process requires me to be connected to the net, otherwise it stops at step 1. Maybe you've got a tips with the Wifi disabled ?

Unless I switch everything over to Linux which installs naturally in a few minutes, I can't see any solution for reinstalling this machine under macOS :'(

Do you have any ideas?

Few screen captures.

Changing the date stops the installation process :(

The process needs to be connected to internet...

And the process with actual date and internet connection for signing in.

MFA...

RRRhhhhhh...

The installer version

If it’ll boot—thes eold versions are limited—then try loading the newest version of macOS when booting Recovery, with Option-Command-R.

If that fails (Macs that never got as far as macOS 10.12 or so are tougher to boot), create a bootable installer on another Mac, and use that.

Lee Kabilyo if yours is a 2010 model year MacBook Air (the subject of this Discussion) the only practicable solution is described in Skrat44's post above: make an appointment with an Apple Store convenient to you and bring it to them.

Official Apple Support

That changes things. That Mac shipped with OS installation discs that should accompany it from cradle to grave, so there are additional options.

Your question would be more appropriately asked in the MacBook Pro Community. This one concerns the MacBook Air, which does not have an optical drive.

the thing with the time worked, didn't change tho same problem.

Alguém me ajuda por favor não sei oq fazer 😔

There is no choice to connect via Ethernet, only WiFi.

I’ve been trying to reinstall OS X El Capitan to my MacBook Pro and after logging my Apple ID, it gave an error 403???

How can I resolve this problem?

Thanks
