All right, but I should be able to drive the monitor with the the Radeon VII DP to LG USB-C should work, right? - Any thoughts how I could achieve that? I may change to iMacPro1,1 Pro Apps (No iGPU) since I use this system for video editing with Adobe apps and Da Vinci Resolve. Like in Pics...

In that case I used the tunderbolt 3 connectors of the z390 designare to the USB-C on the LG monitor. I knew the monitor is not Thunderbolt so that shouldn't work but I was curious to see. I also tried in both directions: USB-C from the z390 designare to DP on the Monitor - It does freeze. DP...

Hey @CaseySJ Yes, The monitor works with hdmi to hdmi and DP to DP from my Radeon VII (with both Mojave and Catalina). I also tried usb-c to usb-c, it does freeze. (Both Mojave and Catalina) Then I bought a Usb-c to DP, same story, it freezes. (Both Mojave and Catalina) Also, I don't have the...

Yes, that strange name partition is still there in the Bios, but since you said it shouldn't make any problem I'm fine with that.

@CaseySJ Now that this part is sorted let talk about the elephant in the room, I'm sorry if I'm bothering you. Please bear with me! I did the update to Catalina mainly because I got a new LG USB-C display (only USB-C, no Thunderbolt) monitor that does't work on the Mojave system. It make...

Good, thanks! I did clean CMOS and set up the BIOS again.

VRAM Resent and cold boot didn't work. I think is also missing the OC folder you mentioned.

Ok, that's good to know. So now everything is much clear to me. Many thanks for your help!

@CaseySJ Also, There is a strange name in the Bios Boot for the Catalina Mojave SSD: - Clover Start boot.efi at CATALINA (P5: Samsung SSD 850 EVO 250GB) Is that normal?

I'm sorry I think I didn't select properly verbose mode during that test. Anyway good news (I hope)! Now everything works as it supposed to work. -Both Mojave and Catalina boot properly. -Mojave boots with and without Catalina SSD attached, during the clover boot Mojave shows 10.14.6 version...

After all the steps above and cleaned the NVRAM the version now shows 10.14.6 It does not boot anyway. It appears again the "No entry" symbol.

Just few more info: @CaseySJ - I tried to remove the Mojave SSD and boot only with the Catalina SSD on the system. It does boot correctly. - I tried to activate verbose mode on the Mojave boot, again only the "No entry" symbol appeared. However I did notice something that make me think I...

Hi @CaseySJ Thanks for your answer I'll try to be as clear as possible: Some questions/comments/statements Catalina was a fresh installation. Yes It was a fresh installation Catalina SSD has its own EFI partition with its own EFI folder. Yes, I at first I used the Catalina fresh...

Thanks for your answer Jiffyslot, However I don't think the problem is the EFI folder. The bios is pointing to the right disk: When I want to boot on the new Catalina installation I select the Catalina SSD after pressing F12 on Bios boot. The same when I want to boot to my previous Mojave, I...

Hi everyone. I had a Mojave Clover installation that worked very well for the past 6 months, so I though it was the time to update to Catalina. I have Mojave on a Sabrent 1TB NVMe and yesterday I made a fresh Catalina Installation to a spare 250gb Samsung 850 Evo. Let call them SSD Mojave and...
