Could not compile it with cc, 10.14 removed multi arch support!:

Code: 
ld: warning: The i386 architecture is deprecated for macOS (remove from the Xcode build setting: ARCHS)
ld: warning: ignoring file /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libSystem.tbd, missing required architecture i386 in file /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libSystem.tbd
ld: dynamic main executables must link with libSystem.dylib for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

So I used Go language to compile a 32 bit hello world and... it got stuck again. No output, no error, no nothing! Even attaching a debugger gets stuck. The only thing I get in Console app after cancelling the stuck app is:

kernel sleep interrupted

Clearly the OS puts all 32 bit apps into sleep.

Looks like I need to give up. For the past 8 years I only upgraded the OS on this MBP, never needed to have a fresh install.

That is so weird and I unfortunately have no explanation for you. If you ever figure it out, by all means fill us in! I just feel you will most likely save time and effort with a reinstall.

You do know you can re-install the OS over a previous installation without wiping it, right? Use the patched installer and just select the existing drive without erasing it in Disk Utility. Although an 8 year old system might benefit from a fresh cleanup anyways!

If anybody is curious about the boot flag I mentioned earlier, it's -no32exec, but it says (page 5) that will display an error, not just hang. Most likely irrelevant to your problem, but potentially useful.

Has anyone done a Mojave upgrade on a Mac Mini with HD6xxxx video card? Re-reading the thread sticky, it sounds like it would make the system 'almost unusable' - but this is referring to iMacs - I think the Mac Mini's may be in a similar boat.
Click to expand...

I have one of those. There is no hope for us dude! You will have to keep using it with either HighSierra, or Windows.
By the way the processors in that year minis came also with a defect plus bad design on cooling, well the systems run really hot all the time (especially in Windows). Thank apple for the frying pan, I can make you some tasty scrambled eggs.

Please just repair your system correctly, which will rid you of any GPU kernel panic issues.

Thank you for this great video. It is one of the pieces needed plus some research for finding the the right part, since we don't have old boards gathering dust. You have been a tremendous help to many of us mac users.
By the way. What do you think is better to use EEF-SX0E331ER rated at 2.5V, or the ECASD60D337M007K00 rated at 2V and visually thicker?

Thanks for confirming the hot mess...No kidding on the hardware / design issue? Time to upgrade it appears. BTW, I had a failed motherboard about 3 years in, got a warrant replacement with apple care the last week of coverage... Alright, thankfully I didn't go down the rabbit hole of trying to install using the patch. Cool solution for many, just not for me. cheers

Has anyone had issues with their external webcams? iSight has known issues, but I'm running into issues with my external logitech webcam. It appears to fire up whenever I launch a camera based application, asks for permission, but shows nothing but a black screen. Puzzled by this. Anyone figure it out?

I'd recommend the 2.5V rated cap. Just ensure it's 330 uF, and that it has a second ground pad in the middle of the cap. This will ensure it'll actually fit onto the board. A good replacement can be found on Louis Rossmann's site here.

I have an iMac 12,1 with a Radeon 6770 video card.
Mojave beta is a bit stuttery but the colours are correct.
Mojave final release is smoother but colours are inverted.
Both running from external SSD

I recently made a video about that here.

On a tangential question, has anyone with a flashed GTX680 tried using the linux non-free nvidia drivers under Ubuntu or Fedora? I didn't test this before I flashed the original PC card. While the nouveau drivers work fine on the Mac ROM'ed card, the nvidia drivers seem to always end up with a black screen when the greeter should be launching. Almost as if the display back lighting is turned off.

Does anyone think this OS is far, far too complicated for 80% of users?
Click to expand...
No...? It's the same as High Sierra, complexity wise. You should have some familiarity with the Terminal, backups (as always), and a willingness to reinstall your OS if you're messing around with unsupported hardware. But Mojave itself is no more confusing than any prior macOS. What are you talking about?

Sorry to be coming in now and asking that question.
Has anyone managed to install MacOS Mojave on Macbook Pro 13 2012 (no-Retina) using SSD RAID 0 on APFS?
With this APFS Rom patcher could do it?
Click to expand...

The APFS ROM patcher is to bring APFS support to old Macs that don't have it natively. A 2012 MBP both supports APFS and Mojave out of the box, so you shouldn't need any patches...

I just installed it on my 12,1 test machine (forgot it had a Radeon HD 6750M) and saw the same issues. I would call it mostly usable, but it's a big step down from 10.13. I've been combing through the thread to see if there have been any updates to fix it, which would be cool, but I haven't found anything yet. I figure something like that would probably make it to the OP anyway.

I'm going to throw another drive into my main comp, a MBP 5,3, just to see how it plays with Nvidia before I try upgrading. Other than the dark theme, I don't see a lot of reason for anyone without an iPhone (ick) to upgrade anyway, but then who comes here needing a reason, right? The theme is nice though, hopefully it will prod Google to do something about the godawful Android retina burn.

Thanks dosdude1! Another fantastic and helpful release. I'm blaming you for not getting anything else done today! Don't know how much further I can push this old Mac, but it sure is awesome having the ability to try.

Have anyone been successful upgrading to Mojave on a MacPro3,1 with ATI Radeon HD 5770 ?
Click to expand...

The installation will work and it'll boot and run decently, but you won't get graphical acceleration. Upgrade your GPU. See the first page for more info.
[doublepost=1539205029][/doublepost]Anybody else getting a warning in Safari when you go to this specific thread on MacRumors? It almost looks like Apple is finally making an attempt to interfere.

Yes, I certainly am too, starting this morning. Don't think it has anything to do with Apple, though. Safari (and most other browsers) use Google Safe Browsing data to block fraudulent web sites, so I'd blame Google. It could be that Google has identified the download links to macOS Mojave Patcher as potentially dangerous.

This is beyond annoying 'cause, even if you click on the link in the warning to proceed to the web page, you can't do anything once you get here (like refresh the page or click on a link to another page in the thread) without getting the damn warning page blocking your access again! The only solution, for now, is to go into Safari Preferences' Security tab and uncheck the Fraudulent Sites option.

Yes, I am seeing it too in both Safari Technology Review and Safari.
[doublepost=1539208119][/doublepost]Booting from APFS RAID0 is dead unless Apple decides to fix the bless command. They show no signs of wanting to do so.

I see a few references in this thread to Target Display Mode not working properly. Has anyone gotten it to work on a 2011 iMac with AMD 6xx0 graphics? I always figured TDM was a firmware-level thing, not an OS-hardware-driver thing, but if it doesn't work in Mojave, it must not be.

I use my iMac as a home server, usually "headless" with the display acting as a display for my MacBook Pro via Thunderbolt Target Display Mode. (Also sharing its Gigabit Ethernet to the MBP.) While I'd like to have it on Mojave, mostly for OS consistency and continued security updates, and I don't care about the lack of GPU acceleration, losing TDM would be a deal-breaker.
