Cyberdevs Posted June 27, 2020 Share Posted June 27, 2020 I got to admit Big Sur's is performing surprisingly well even on a conventional HDD with APFS format. Spoiler 4 Link to comment Share on other sites More sharing options...

I agree with you. I was using Catalina with NVME and now Big Sur with a conventional SSD and I feel an absurd difference (for the better). If the Beta is like that, imagine the final version.

Yeah exactly, I installed Catalina on many iMac with HDD and the performance wasn't bearable AT ALL, but Big Sur is definitely the winner! Link to comment Share on other sites More sharing options...

I updated my guide to install Big Sur by creating your own installation using a virtual machine as installer. (With pictures) So you don't have to use ready-made DMG/DD. If you already have your Catalina working perfectly with OpenCore, it will theoretically work... I'm stuck here after install.

Thanks to all devs and peeps for all your contributions, patience and dedication.

OrpheusInHell Posted June 27, 2020 Share Posted June 27, 2020 I followed all the steps and it ends up with a kernel panic. I'm not as good as you guys, so I guess I'll wait for a stable bootloader/installer. I'll keep watching this topic though. Link to comment Share on other sites More sharing options...

Also, I see that you're using a TP Archer, I ordered a T6E and TX50E AX3000, do you know if they are supported?

TP T6E must be supported but not sure about TX50E, my TP- T9E works perfectly fine and I have AirDrop working amazingly fast, continuity and hand-off must work but haven't tested them yet.

Oh okay, thanks for the clarity. I never use PCI-e wifi cards before is I have no knowledge about them. All I know is that the TX50E has higher speeds and has Bluetooth built in.

You're welcome, I haven't tested the TX50E but if it works on Catalina it should work with Big Sur as well, the card seems interesting with a built-in bluetooth 5.0. Let me know how it goes when you got your hands on it. Link to comment Share on other sites More sharing options...

Maybe run a tree to show your folder structure? Make sure you entered the folder with Big Sur's UUID. Edited June 27, 2020 by Zhen-zen Link to comment Share on other sites More sharing options...
