Maybe i misread the incremental update. It took me now to straight to 12.7.2. EOF! Thanks for that heads-up regarding the per-requisites for next OSX upgrades. I guess i will stay with Monterey for some good time before leaping again. Do you mean the App Store? I logged in, but the About Info...

@Feartech Sorry for the delayed reply. With small kids one has little time for DIY stuff :P. Today i took the shot to run the install OSX Monterey from application folder(maybe i should have pulled the latest install version, now i am at 12.5.1). Took 30minutes with multiple reboots (every time...

@Feartech : Thanks for your feedback. Now I updated my active KEXTs and OC from v0.7.8 to v0.9.5 using the OCAuxillaryTool. Earlier when my screen saver came up it worked fine. After the KEXT update. I noticed only black screen and no reponse so i had to hard reboot. For the timebeing i...

Dear Community, I am planning to take a shot at updating my current Catalina (10.15.7) hopefully to Ventura (or even Monterey?). I am on my HD530 after removing my GTX960. On OpenCore V0.7.8. Is this possible with my current setup? Should I first upgrade OpenCore to current V0.9.5 and all...

Thanks a lot @Feartech. I am still to test all facets but so far things are look good with Catalina. Since I am not fully in apple Ecosystem I haven't dwelled into iMessage, facetime & iCloud . But atleast AppStore seems to be working which is REALLY good. The audio over HDMI (surprisigly...

Was only a 'sudo' issue

Wow! Just that 3 aforementioned BIOS changes and adjusting config as mentioned remove Graphics framebuffer and putting Lilu as first dict entry(mentioned any where in documentation or why?) did the Job to start installation as expected!! I wonder if this would have also worked without erasing...

My Current BIOS version is: V3805 Date: 16 May 2018. Mabe therefore some settings are not available/cant find/hidden under other names. Disable: Fast Boot -> Disabled Secure Boot -> Disabled Serial/COM Port-> Option not available/ Can't find Parallel Port -> Option not available/ Can't find...

@Feartech I got mad after loosing so many days, I just erased and formated my whole OSX SSD to APFS to start a fresh catalina OC install. Since you meantioned keep only SSDT aml mentioned in guide. I deleted all my SSDTTime generated ones and just downloaded SSDT-EC-USBX-DESKTOP.aml and...

I have 3 options offered in that black screen shell OC picker when I boot from USB installer. EFI/Windows/Install OS Catalina. This Clover Style boot menu comes only when I choose EFI option at the OC picker. When I select this option at OC picker after 1 reboot during Catalina Installation I...

Can it be that my Clover EFI setup is no where near ready for either Open Core or anything higher than Sierra? Maybe I need to get that fixed before attempting anything OC or update OSX?? What changes might be required in CLOVER? Should I populate the CLOVER/drivers* /kext/other & APCI...

setup an opencore usb installer correctly: hopefully done correct this time boot from that: Done install macOS : Started Installation screen/progress bar. After 4 to 5 minutes it rebooted. keep booting from your opencore usb installer until you get to the desktop: Just a question here. yes I did...

My edited EFI below. Yes I did respect your SMBIOS suggestion but since you said this data is not required at the time of installationa and one can do it postinstall I left it the section so. Meanwhile your reply cam, I had already updated it with new values generated using iMac17,1. With all...

No wonder Dortania OC guide starts with those Wise words "[CRUCIAL] Time and patience." Hope I made a better OC Catalina USB installer(latest OC, SSDTTime-> so i have separate SSDT_EC & SSDT_USBX) for my setup now. I can start install catalina every single time but problem starts after first...

Using Munkis Script I downloaded both Catalina 10.15.7 and Big sur 11.6.2. 1. I hoped starting fresh using the latest OC version and creating an installer with standard settings would be enough to get the install done rather than copying someones setup not knowing what all the fuzz is about. I...

Any particular version of Catalina? I generated my Serials using genSMBIOS with imac18,3. The EFI folders from some Z170i users use imac17,1 So if use their EFI setup should I change the 17,1 to 18,3? does SystemProductName variable matter ? also ROM?

Okay I will try to make a fresh OC USB installer either using Catalina or Big Sur. Do you know if at the installation screen should I use the Diskutlity to format my SSD to APFS explicitly or can continue I installtation like did last time without loosing Data?

Now Since I can access Terminal. Is it good idea to delete all EFI CLOVER data and just copy the OC installer EFI folder to OSX SSD EFI and reboot ? Will that work? On reboot should I choose OC USB Installer again?

@Feartech Thanks again for the Link. I am wondering how I can get all this system Information, create any necessary files or copy something to somewhere without being able to boot to my OSX Desktop or a shell? The only think working now is my old Sierra Unibeast Installer. Here I can get to the...

Strange that Unibeast Catalina Installer ist also getting stuck at 1683. So it seems nothing to do with the USB installer content. I am not sure what this else could be. Most of the thread related to 1683 Issues talks about the EC. Especially EC_USBX. Not sure if I need to generate one...
