Asus X299 - Support

[izo1]

Help! Please: my USB install goes thru the first 9 min preinstall, reboots, blackscreen with Apple logo and status bar. Nothing seems to be happening, status bar stays dark.

Any advice? Thank you, I know that everyone on this forum is volunteer and I don't take anyone for granted!

Are you following the guide step by step?

And did you create the USB installer the proper way?

If it stays black give it some time, that used to happen to me too with some installs, it would stay black for a few mins then either reboot or come back with a load bar.

If it stays black for like 15 mins then you need to hard reset, wipe the SSD through disk utility by booting from your USB installer, then start over again.

The guide that you read is very detailed so let us know what steps don't make sense and we can help...but generally I never had problems with the guide I know it seems complicated at first.

I am running on 1704 and while its not great, it seems to work. Same settings as 1503......I also run Catalina on this system (on another drive), and seems fine.....

I've started fresh today and I am going to give Mojave a try. I have an older Radeon Card that came from an old Mac Pro, I hope it will work for the installation. I will get a new AMD this coming week to replace it with and sell my GTX 1080ti.

I did a hard reset on the bios before starting today so that I could go thru all the bios settings according to KGP. I just finished that process, so far, so good.

@mm2margaret, I have read many of your posts. You seem to be very good with this build, I really appreciate your participation and willingness to help. Question, do you have to use the bios settings for overclocking or is that an option? Also, the only version of Mojave I have is 10.14.5?

Thanks,

In making the USB installer, the Terminal gives error message that it cannot proceed with installation of InstallESDDmg.pkg and other items in sharedsupport folder.

Is it OK to copy and paste Install macOS Mojave.app to the USB drive? Instead of using the Terminal cmd as is detailed in D.3 of KGP's procedure?

You can make a Mojave 10.14.5 USB installer by other means. Here’s how from Apple:

Create a bootable installer for macOS - Apple Support

Use an external drive or secondary volume as a startup disk from which to install macOS.

support.apple.com

Then just mount the EFI of that USB and put on KGPs EFI (with a correct TCAdjust kext) and it’ll boot.

Thanks @izo1, again it only lets you download 10.14.5.

KGP's version is 10.14.4. Maybe it doesn't make a difference. I will keep trying, I've gone over the procedures (carefully following) several times. I think I did everything correctly, except for adding these files:

Now add the following files to your "Install macOS Mojave.app" with the following terminal commands:

Code:
sudo cp ./041-56507/InstallESDDmg.pkg /Applications/Install\ macOS\ Mojave.app/Contents/SharedSupport/InstallESD.dmg
sudo cp ./041-56507/AppleDiagnostics.dmg /Applications/Install\ macOS\ Mojave.app/Contents/SharedSupport/
sudo cp ./041-56507/AppleDiagnostics.chunklist /Applications/Install\ macOS\ Mojave.app/Contents/SharedSupport/
sudo cp ./041-56507/BaseSystem.dmg /Applications/Install\ macOS\ Mojave.app/Contents/SharedSupport/
sudo cp ./041-56507/BaseSystem.chunklist /Applications/Install\ macOS\ Mojave.app/Contents/SharedSupport/

Thanks for your continuing help!

No worries we are all helping each other

Don’t worry about .4 and .5.

The latest is .5.

You can just use the regular guide from Apple I posted above to make a boot installer and then use something like MountEFI or Clover Configurator to mount your USB EFI partition and put in the kgp EFI. Look for the TCAdjust section in the guide, and match it to your CPU cores and then put that in the kext/other folder on your USB EFI so you can boot the installer properly.

You should start with a fresh USB. Just format it as HFS+ before you do anything.

Once you are booted into your installed macOS (on your SSD), it’s now time to continue with the guide and create correct config plist and the correct kexts. It takes time to tweak it but the kgp EFI is a very, very good starter.

Note you will always need the TCAdjust kext or your system won’t boot.

Well, really I did do some overclocking, but then just went back to default settings. The added speed just wasn't that big of a deal, at least for me. I just prefer stability over any of the improvements. Others may feel differently, and that's great. I like it the way it is.

By the way, a Sapphire Nitro RX580 8GB can be had used on e-Bay for as little as $125.00. How do I know this? Because I just bought one....going to use it for as an external GPU and maybe for some other things.....really, it's a pretty good card.....

I totally agree with you about overclocking. I've never liked the idea of possibly burning up a perfectly good CPU.

Do you think a used card from eBay is safe to buy? How do you like the VII?

Modern CPUs can’t “burn”. There’s a lot of safety features built in. Matter of fact all these Intel CPUs have so much headroom it’s great but you will need good cooling or else you will run them very hot loud and throttle or shutdown.

A minor speed bump is good unless you have a exotic cooling solution.

Used cards are good just avoid mining cards if you can.

Radeon VII is a great GPU. It’s what’s Vega 64 should have been.
