[Solved] I'm getting "macOS could not be installed on your computer" error when trying to install HS

[Crispis03]

I'm trying to install SO High Sierra but i'm getting the following error: "macOS could not be installed on your computer".

I followed the steps, I tried with just one RAM strike (1x8gb), the USB in the backpanel 2.0m, and I also changed the Product Name in the clover in SMBIOS to MacBookPro14,2, either way I'm getting the same error :S

Theoretically the computer is compatible, I bought the components following your guide:

• Intel Core i5-7600 3.5GHz BOX
• Gigabyte GA-Z270P-D3
• EVGA GeForce GTX 1050 FTW Gaming 2GB GDDR5
• Corsair Vengeance LPX DDR4 2133 PC4-17000 16GB 2x8GB CL13
• Samsung 850 Evo SSD Series 250GB SATA3

Bios:

• XHCI enable
• Legacy usb support enable
• Vt-d disable
• Internal graphics auto
• Other os
• Storage boot option control legacy (Tambien he probado en uefi)
• Serial port disable
• Sata controler enable
• Sata mode ahci
• Agressive lmp support enable

Please, can someone help me with this?? Many thanks in advance, and happy new year!!

Why ?
You have a Desktop not a Laptop - Try iMac14,2.

Hi P1LGRIM, thank you for your answer... The first time i tried with iMac14,2 but it didn't work, so I changed to MacBookPro14,2 just to see if that was the problem, but neither of them worked...

Looking at your log image it seems to me that there may be a problem with the firmware (which Apple updates before the upgrade).
The firmware information is stored in the config.plist and Clover is supposed to report correct values if the config information is too old. There may be some confusion induced by your use of MacBookPro14,2 information combined with iMac14,2 information.

Anyway, check that your Clover is up to date and it would not hurt to regenerate SMBIOS information in your config.plist with the latest Clover Configurator.

Thank you so much for your help P1LGRIM!!

I finally did it!! After trying with the default SMBIOS and the latest version of Clover with no results, I created again the booteable usb with the Unibeast and this time it let me install the SO without problems!

Unfortunately, now I do have an issue with the audio (mobo Gigabyte GA-Z270P-D3/Realtek ALC887). I selected the drivers ALC887/888b in Multibeast (10.2.0) and I'm getting this message in the audio "no output devices found". I also tried with ALC887/888b Legacy and VoodooHDA with same results. Do you have a clue of what can be happening?

Also the VGA detected NVIDIA Web Drivers without problems but the port speed is 4x, and I'm not sure if this is fine or it should be 16x?

Thank you so so much for all your help!

Best,

For assistance with Audio you should post in the Audio forum.
Read the 'sticky' guides first and be sure to comply with the Problem Reporting instructions or you will not get any help.

Likewise for graphics there is a Graphics forum.

Perfect!! No worries, I'll try first with the guides...

Thank you so much!
