Hi Matt. How often do you update? I always get nervous with new updates. I did the recent monetary one and my next update will probably be in a year lol.
After running the patched updater does the software updater then keep you up to date? or do you need to run through this every time? IE if you get to 11.5 can you go to 11.6 via software update or do you need to over write your system each patch?
Because, there are many people who can't afford a MacBook upgrade, or just wants to keep their old ones. You also can't install new applications or application updates provided by apple unless if you're in BigSur.
Hello there: I have managed to run Big Sur on my 2008 MacBook using OpenCore Legacy Patcher instead; as mine is identical to yours (mid-2008 MacBook A1278 with the upgraded Core 2 Duo P8600) sans the different keyboard layout, it should work for yours as well.
Downloadlng failed when i click the download what should i do ?? it saying The macOS download failed. The reason for this is unknown since the download should not have cut out, unless something outside of the patcher was messing with it. Please go back and try again. This is not a patcher bug.
Im having a problem in the middle of downloading process, it says (Im using mid 2012 catalina) “Error 1x28 message: % total %received %Xford average speed time time time current Dload Upload Total Spent 0 0 0 0 0 0 0” What would be the problem?
Based on bensova.gitbook.io yours should be supported, but you may need a few more patches (WiFi patch to restore WiFi function is cited). Because yours is pretty much the oldest supported Mac, I would make a backup of all data and an external boot source before attempting. May need to update to an older OS first if you are not using APFS format already. Depends on what operating system you have already. I have a 2009 Macbook 6,1 (could probably do the update, maybe boot given enough time) and am not going further than High Sierra on it, unless I switch from my antiquated HDD to SSD, then only to Catalina. I could purchase a reasonably new refurb that would run Big Sur for a couple hundred bucks, and could update that more easily. (wouldn't be able to show off my techno-prowess, but would be more prepared for inevitable future updates.) Had to ask myself what Big Sur has that my Macbook 6.1 needs to do and that I can't do without... Anyone else have input/opinion?

You have to do a fresh format. Earlier versions of mac os used a different file structure. Big Sur and catalina both use the one mentioned in the video. If your mac is unsupported for catalina then its likely you don't have the correct readable file sructure. Wipe the disk do a fresh install and you should be good.
