Hello,
I have a problem, can’t boot my MB 5,1. 2x X5690.
1.) I backuped AirPortBrcm4331.kext /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/
I put it on my Desktop and Flashdrive.
2.) I downloaded Mojave Installation, created Mojave USB with
sudo /Applications/Install\ macOS\Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
3.) I took out SATA Mojave SSD from bay 1 and second SSD from bay 2 (I have Windows 7 installed in Bay 2), no other drives -> Mac booted from USB.
4.) I booted from Mojave USB. (from step 2)
> Disabled SIP with csrutil disable in terminal.
> nvram boot-args="-no_compat_check" to change boot-args. (Nothing happed as answer.)
> Enabled SIP csrutil enable
5.) Put my SATA Mojave SSD to SATA-USB adapter. Boot it from my Macbook Pro 2012.
6.) Downloaded and updated from Mojave to Catalina on My MBP to SATA SSD. No clean instal.
7.) Put SATA SSD back to my MP 5,1. Can't boot. Black screen. I have Vega 64 instaled and RX 580 instaled. Each one to one display. Ill try with GT120.
I booted from Mojave Install USB, with no SATA drives in Mac (step 4) - I thought it works the same as recovery. Or not?
Should I have booted to recovery on my old Mojave SATA SSD and use
nvram boot-args="-no_compat_check"?
Should I boot to USB Mojave Install with Catalina SATA SSD in and use
nvram boot-args="-no_compat_check"? I don't know if I till can with RX 580 without boots screen and GT120 (I think it will not boot to Mojave USB). I can easy boot from Mojave USB only without SATA drives.
I appreciate any suggestions.
edit: still no luck. I’ve been trying to fix it whole day.
- Reinstalled clean Catalina to the SATA SSD connect via USB-SATA adapter from my MBP2012. Put back to Mac Pro. No boot. Just chime. Black screen. Mac turns off immediately if I press of power button again.
- Boot from USB Mojave Install disk, did
nvram boot-args="-no_compat_check" with SIP disabled. Put Clean Catalina SATA SSD back in. Same. No boot.
- Added Mac-F221BEC8 to SupportedBoardIds and added MacPro5,1 to SupportedModelProperties in
System/Library/CoreServices/PlatformSupport.plist and in
Volume/Preboot/xxxx-xxxxx-xxxx-xxxx/System/Library/CoreServices/PlatformSupport.plist
a.) I tried to boot it. Mojave update to Catalina SATA SSD connected to MBP via SATA-USB adapter.
b.) Second try. I did with clean Catalina SATA SSD created with SATA-USB adapter connected to MBP.
Still same result. Chime. Black screen with my RX580.
I can boot DosDude Catalina USB. I can boot Mojave USB. I can restore Time Machine back up and boot from SATA SSD back to Mojave. Same SSD. Same SATA port in bay1. Same RX580.
I must be missing something trivial. Thanks for advice.
