2011 Macbookpro won’t boot after multibeast installation

[jonnyweston]

Hi guys,
Listen I was in the middle of installing an express card 34mm for an extra USB port, on to 2011 MacBook Pro, and I was following a new tutorial on how to install 3.0 installation. It all completed fine till I went to reboot it

Unfortunately now however even after successful installation my Mac has decided will no longer wish to boot up.
Is there anybody out there at all and maybe To offer me some advice.

The Mac won’t get past the Apple logo, I think, but then also gives me a very long progress bar.
Anything anybody can do to help would be appreciated.

Thank you very much,
Jonny Weston

After about 20 hours at this I can absolutely recommend that nobody try and install multibeast on to a macbookpro - totally wasted on of ,y machines

Hi there,

MultiBeast was not designed to be used on a real Mac.

What did you use it for?

Can you boot into macOS Recovery mode?



P.S: Please complete your hardware Profile as has been hinted at

Well, I think possibly you are right.

Most folks have been using the Multibeast / Clover software to allow the installation of USB 3 ports on ExpressCard ports.

it is a little ironic though that folks do their best to replicate the exact hardware of Mac machines to fool OSX into allowing an installation....
...but that actually having the exact specification using Mac hardware fails LOL.

I didn’t actually realise originally that this was the same software that was used for the hackintosh - ‘‘tis very clever

Oh sorry.... missed a trick - in answer to your question, no it won’t let me into OSX recovery.

The machine locks up no matter which one of the three options I choose in the clover menu.

Hmmm, but you shouldn't have a Clover menu. That messes with the real Mac UEFI firmware. Do you have any other Mac hardware? I'm thinking you should mount the Macbook SSD/HDD EFI partition on another machine and delete the EFI folder contents installed by Clover. It's method of booting into Recovery mode is different from a real Mac - which is by keyboard, as you know.

Yeah I have 4 other 17” i7 16gb macbookpro machines sitting on my AV stock here too, they’re identical in every way.
I’ve taken this as an opportunity to retrofit the machines with SSD drives, and waiting for amazing to deliver 5 crucial drives today.

If you don’t mind me asking, is the EFI folder installed by clover easy to locate? Is it just a case of deinstalling it?

One thing that I am av ke to do is to get into the clover settings, sorry I maybe mislead you - that is one thing that I am actually able to do - but inhonestlybdon’t Really know much about what to do in there.

Do you have a link to this guide that you followed ? I'd like to see exactly how they are using Multibeast.

Make sure to tell the author of the guide you followed that Multibeast was never designed to do what they are attempting to use it for. It's designed solely for use on Windows based PCs that already have macOS installed. Unibeast can safely be used on a MacBook Pro to create a USB installer. Multibeast is just not needed for any real Mac computer.

If you've already rebooted the MBP after installing Clover bootloader you may have to reflash or replace the physical EFI bootrom chip or possibly reflash it. That's been what most have had to do to get their Mac functional again. There are many threads on this topic to peruse.

Yeah here’s one of them.
