That doesn't bother me too much if it means the file system is better. Should all the new file system features work on 5,1 MacBook? It isn't too hardware dependent and is more of a software update in HS?
I edited the opening post in this thread to indicate MacBook5,1 works without issue. 
It doesn't sound like the optical drive. Is it the fan? Dunno about the HD. You might want to start a new thread on this.
Heh. That makes little sense to me.

The most robust approach is to format your destination drive as APFS from the Disk Utility application booted from a USB memory stick installed by the High Sierra Patch application and then using an install with migration.

Ah my bad I'm at work so probably not even been reading all your replies properly! I will start a separate thread because it's bugging me what it could be!!
@jhowarth I read online earlier that HS gives you the option to transfer to APFS without losing data but reverting back wouldn't save all your data - I wouldn't want to format my hard drive before a HS install as I would lose all my data/apps and wouldn't want a fresh install

Is this how EVERY machine with APFS boots or just the unsupported ones? And would it boot like this upon the Final Release of HS next week? I am intrigued by the new file system as I don't like knowing something better is out there and I'm not making the most of it.
When I do upgrade to HS using your patch with the final release, how would YOU advise updating to APFS?
Is there any type of workaround or do I need to swap out the card?
The EFI shell boot prompt is just on the unsupported machines as they don't have the updated EFI firmware to make them aware of APFS as a valid boot volume. The one exception would be the MacPro 4,1 which could be flashed to the MacPro 5,1 firmware which would get it the new APFS-aware EFI firmware update. That would be the one case where you wouldn't want to apply the APFS patch on an unsupported machine.
I may switch to APFS then as I never watched my Mac boot up and even if I did it's not how it boots but what's on it that I'm bothered about. As long as APFS will function properly on my 5,1 MacBook. When upgrading from sierra patch to HS what would be the best way to switch to the new file system? Whilst keeping my Mac how it is and not doing a fresh install..
Yes, the reported workaround (earlier in this thread) is to get an nVidia GTX 680 2 GB GPU.
People have tried copying over the kext from 10.12 without success so far. Since those particular drivers were rewritten for 10.13. the system may expect to see those changes present in the loaded kernel video driver. Fortunately, the stock HD 2600 XT drivers still work fine under 10.13 on a MacPro 3,1.
Yes, that works too, but no Metal support and slow slow slow for any heavy graphics. It will get you installed and booted at least.
Would really like to get my 5770 working with High Sierra as the old 2600XT doesn't have the Mini DisplayPort connection I need to drive a 27" Cinema Display. Any ideas please guys?
Unfortunately, your best bet is to either switch to a compatible nVidia card or put back in the original HD 2600 XT and purchase a Mini DisplayPort to DVI cable.
so can I use the normal way to launch Disk Utility and convert it?
(Press "R" into Recovery Mode and launch Disk Utility)
or I have to use Disk Utility in my USB driver made form dosdude1's patcher tool?
Thank you.
Easiest fix ever! There is a trackpad adjustment screw. Lefty loosey, righty tighty.Picked up a used late 2008 Unibody aluminum MacBook5,1 Core 2 Duo 2.0 GHz to replace my wife's 2008 white MacBook kitchen computer (a MacBook4,1 which is stuck on 10.7.5 and therefore can't get any modern browser). I happened to have 4 GB RAM I wasn't using and transferred over the 128 GB SSD from the MacBook, and then installed the patched High Sierra. Everything works... except the trackpad click being a big sticky in one spot. The focally sticky trackpad has nothing to do with the patch though of course, just the perils of buying ancient used equipment.
Click intensity on the right and left sides are still not absolutely identical, but the feel for both is still good and the most important thing is now button clicks all register everywhere on the trackpad.
The Recovery partition installed with the patched High Sierra won't be bootable on unsupported machines as it is an APFS volume and EFI shell approach to booting those on unsupported supported machines hasn't been extended to handle the recovery partition volumes. You will have to launch Disk Utility from the USB installer created by the High Sierra Patch application. However, the 'Convert to APFS...' option will only be available for SSD drives in the initial release. You could try to use 'diskutil apfs convert' from the Terminal for Fusion or hard drives but the results from that have been mixed. Also, if you install a patched High Sierra on an unsupported machine and then decide to convert the boot volume to APFS, you have to repeat the post install patching to insure that the APFS patch is applied.
I have the ill fated Mac Pro 3,1 and the AMD card... bad luck.
Where can I find a card like that nVidia for my MP?
[doublepost=1505842946][/doublepost]
That is my case. Apple replaced the original card, which stop working a few months ago.
Sad.
I ordered yesterday an used GTX 680 one from Amazon. Waiting to receive it for testing on my MacPro 3,1. It was a cheaper alternative than finding a 5,1 MacPro ..............I heard the card(new) can be bought also in Germany but it will cost around 600 €, three times more expensive than the used one.
Thanks for the update dosdude, my hero. Since Mac OS X 10.13 is out officially, how do I update to the stock OS X 10.13? Same technique as usual through terminal? Is out out yet on your servers?
I don't believe the 10.13 final release is out yet. iOS 11 was released today, not macOS High Sierra, as far as I'm aware.
