Until recently, I had a Dell E-5550 that broke (the motherboard was broken) and now I would buy another Dell, so I'm interested in which one you think is good to be able to install Venura or Monterey on it. I am interested in the following models: - 2018 year (7390 or 7490 model) - 2019 year (7300 or 7400 model) - 2020 year (7310 or 7410 model) - 2021 year (7320 or 7420 model) I'm interested in your opinion and for a choice, which one should I buy and which one would be best compatible with the installation of the OSX system? Or you have another suggestion for buying? thx..

I rebooted the NVRAM and now everything is fine as far as Big Sur, I don't get any errors and all kext upgraded and open core is upgraded to 0.7.0 version... thx @Bronxteck And thx Hervé for your answer I will now stay on that version 0.7.0 and will not upgrade it anymore. The only problem I have now is dualboot with windows, when I turn on the laptop when I choose to want windows, my computer simply restarts (see attached video). I tried enabling SyncRuntimePermissions under Booter / Quirks but it's the same. I also noticed that every time I turn on the laptop the opencore makes some log in the EFI folder. Attached is also config.plist and opencore log. I would be grateful if someone would help me and solve the remaining problems with log and dualboot.. config.plist.zip opencore-2021-06-27-070916.txt.zip video.zip

I find post from Sergeant where is he installed BigSur on his E5550 so I take his EFI folder and it is good and everything is working. So i update kext and OpenCore but I have just one problem. When it boot you can see on picture that OpenCore is installed with last versions, but when I open OpenCore Configurator it says that I have old version of OpenCore. So how can I fix it.

HY, I have dualboot Catalina and Win10 on my E5550 with Clover bootloader. Now I want to upgrade my Catalina with BigSur, and I want to create EFI boot usb with OC Gen-X. My E555O is with: i5-5300U @2.3 GHz CPU intel HD 5500 graphics 12GB DDR3 (1600 Mhz) RAM 256GB SSD DW1560 wireless So I will be grateful if someone tells me what to choose from OC Gen-X to create EFI and if I install it will it remain dualboot with windows? Or can someone send me EFI folder.. thx..

So I must chose: Install for UEFI booting only Install Clover in the ESP UEFI Drivers\Recommended Drivers ApfsDriverLoader AptioMemoryFix AudioDxe DataHubDxe FSInject HFSPlus SMCHelper (leave off if you have VirtualSMC.kext in bootpack) Additional drivers PartitionDxe Themes (Optional) nothing else from: Recommended driver (AudioDxe, FSInject, SMCHelper, XhciDxe) FileValut 2 BIOS Drivers 64 bit (AppleImageCodec, AppleKeyAggregator, AppleUITheme, FirmwareVolume) Human Interface Devices (AptioInputFix, Ps2MouseDxe, UsbKbDxe, UsbMosueDxe) File System drivers (ApfsDriverLoader, Fat, VBoxExt2, VBoxExt4, VBoxHfs, VBoxIso9600) FileValut 2 UEFI Drivers (AppleImageCodec, AppleKeyAggregator, AppleKeyFeeder, AppleUITheme, FirmwareVolume, HashServiceFix) Like on picture, is it ok?

Hy Can someone tell me what options I must choose when I install clover 2.5k-5103 or mark them on attached picture for my Dell E5550 and Catalina 10.15.3? thx..
