Will there be a patcher available when big sur is released? on dosdude1's website?
Patience my friend :p. I'm just as anxious as you are to get Big Sur on unsupported Macs, but keep in mind the community is doing this entirely for free and bugging them for a patcher won't make it go any faster.

I'm sure they'll get a patcher out as fast as possible once one is stable enough to release.

And also, you all for keeping our older Macs alive! I've loved watching this thread (even if I didn't understand half of it :p).
 
Simply don't use it, write your own patcher and don't bore us offending the genial developers here, kindly giving support to us.
Forgive me, I didn’t mean to offend anyone let alone developers. That was not my intention. Everyone does an amazing job as getting the latest OS working for all of us. I simply thought there was an easy usb installer created. Like I said I’m no wizard when it come to terminal. Last time I installed big sur and using terminal commands Screwed up my mac and I had to resort back to Mojave.

@dosdude1 has been fairly quiet about his own work, and honestly, with how much incredible work he's done over the past few years, it's fine if he can't do it and would prefer to focus on other things. I wouldn't hold my breath for a patcher as comprehensive as his. The micro patcher works well enough from what others say.
 
If this is your working machine, do not make Big Sur your main boot.

No, that's a spare one I'm selling, my main it's a MBP9,2 and I was thinking about that, if I should left a partition or any spare drive with Catalina in case of panic or any problem.

It's not safe to use this in a main working machine?

I noticed in the Big Sur RC 2 Candidate released today, in the Overview window, the word "Beta" is no longer used.

Same config here. I dropped the Catalina partition a while back. (used Disk Utility and created a DMG) Make sure you got a bootable USB stick (I used Micropatcher 0.5.0) and keep TimeMachine backups uptodate. I haven't seen any issues. Never lost any data since beta day one. Apart from enabling Wifi after updating which must be done using a full installer. But thats about it.
 
You know what I really don't understand...I ran the InstallAssistant.pkg, it takes just seconds to create the MacOS Big Sur installer in the Application Folder while the InstallAssistant.pkg is not even on the same disk...Magic???

Initially I thought it was just a mount point or an alias, instead even removing the InstallAssistant.pkg the few seconds extracted content it's still on Applications folder, very fast apple decompression algorithm.

There's some other magic going on here, I have to recall my earlier message here, I normally copy the InstallAssistant.pkg to my external disk, next I delete the original from my OS SSD, next I open the InstallAssistant.pkg from the external disk, this time I forgot though, it was still on the SSD.
Pretty sure most of the App files are already standard on the disk somewhere deep inside the System, next the installer moves the SharedSupport.dmg in place, actually it just sets a Tag in the Dir, that's it.
It's impossible to unpack 12 GB in seconds and copy it to the SSD, my SSD is a Samsung 640 Pro SATA one, write speed around 540 MB/s...so...impossible.

Edit: I just saw 2 extra disks in /System/Volumes/, when I deleted those I got about 12 GB back on my SSD, me says it's moved from that position to the SSD, it is actually already on the SSD, just in another place, The 2 disks where both called "Sharedsupport" with Update Folder and some other files in it.

Guys, if you're currently on RC 1, do yourselves a favor and don't upgrade to RC 2. It's really not worth it.
