Hi there! Unfortunately, no- this is limited just to the Mac Pro, which has a very different architecture.

Nope, the hifi will not charge any batteries that are installed.

you just need to have a card with the original EFI from Apple- there’s some other cards around, like the Radeon 4870 for example. It may work with newer “compatible” cards like those from Macvidcards.com, but I’m not sure.

You should be able to clone that, yeah. I’ve done it going the opposite way before with no real issues.

No, it can definitely be done in El Capitan - that’s how I’ve done it a few times now. You just have to disable SIP with El Capitan, but the directions for that are in the first few steps. Hope it helps!

Hi Nick,

Based on your hardware profile, you have the very first Mac Pro, which I believe can be flashed from a 1,1 to a 2,1 - but I have not done that process myself so I am afraid I can’t speak to how it works. I believe this forum thread (also on Netkas) may have the information you need.

Hi Frank,

The guy on YouTube is correct, System Integrity Protection (SIP) was a feature introduced in 2015 with El Capitan (v 10.11). I don’t remember exactly when the recovery partition came into existence, but I know that 10.6 definitely does not have it. What I would recommend is upgrading via Software Update to 10.6.8, and then once you have access the Mac App Store you should be able to get the last “supported” version of macOS, which would be El Capitan. [http://Get El Capitan|This link here] should let you download it from the Mac App Store.

Once you have El Capitan installed you should be able to follow the tutorial.

Hi @stu,

Hmm, I assume that’s dosdude’s patch tool? I’m not entirely sure though, I haven’t heard of anyone going to Mojave without flashing first. I’m not 100% sure if you can flash, but you should be able to in theory at least. The tricky bit is you’ll need the original GPU still installed to do the flash.

What firmware is your mac on at present? You can find it in System Information under the hardware overview- it’s labeled Boot ROM Version.

Hi everyone,

I did a bit of research - it seems like maybe it’s a problem with it looking for the firmware update file that happens to some people. There’s some information and directions on this page, post #964 about half way down the page from user Pigsyn. Give it a shot!

Hi Kenneth,

Sounds like that’s Gatekeeper at work. If you right click on the application and click open in that menu, it should give you an option to proceed when that dialog box pops up.
