Apple Event: May 7th at 7 am PT
Tried updating the software and it’s stuck on less than a minut even if left overnight.
If I reboot it just restarts the update and gets stuck again. Doesn’t reboot in safe mode. Over 80gb free disk space before update begun. All external hard drives unplugged.
Well, I guess this may be helpful ?
Tips How to Upgrade to Big Sur
There are several points to consider before attempting the upgrade to Big Sur. The most important is Due Diligence on the part of the User and is a Prerequisite for a smooth upgrade.
The below points should all be consider Before attempting the upgrade.
Point # 1 - Are there pre-existing Unresolved Software Issues. They should be resolved prior to upgrading - they may carryover to Big Sur making the system unstable / unusable.
Point # 2 - Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation. The The Built in Security is all that is required.
Point # 2 A - Commercial VPNs should only be used if Mandated by Corporate Head Office for working remotely. Otherwise - ones Privacy and Security touted by the VPN is suspect.
Point # 3 - How to get old versions of macOS ie: Empty Space Requirements specific to the Big Sur. Apple states 35.6 GB Empty Space but suggest 50 GB
Point # 4 - Does the intended computer qualify for the upgrade.
Point # 5 - Are the installed Applications / Extensions compatible with Big Sur. Check with the Developer for compatible Apps / extension or do they offer updates. Same goes for Third Party Drivers for Printer, Scanners etc.
Point # 6 - If upgrading from Mojave and earlier versions of macOS - Remember that Big Sur does not support anything 32 bit. These include Applications, Extensions and Drivers for any devices. There is no workaround.
Point # 6A - To check for 32 bit Applications - a good application to use is Go64 - safe to use.
Point # 7 - Do I have a Rescue Plan In-Place. This comprises having 3 Backups using 2 methods and 1 Off Site incase of Theft, Loss or Natural Disasters. A Time Machine Backup is very useful and can be used to Revert to Previous Working macOS. For additional purposes - two Tested Bootable Clones each to separate external drives. This is insurance incase the upgrades goes sideways. At least one Tested Clone and / or Time Machine Backup should be Off - Site
Point # 8 - To upgrade to Big Sur will requires a quick, stable and reliable Internet Connection - preferred method is via Ethernet Connection.
If not available and using Wifi - move computer as close to the Access Point / Router and disconnect all other devices connected to Wifi. Want the maximum bandwidth for the computer being upgraded to Big Sur.
There are factors:
1 - Like poor Wifi connection
2 - Slow wifi connection
3 - Too many other people downloading at the same time and Apple Severs are overloaded
4 - Software on the computer interfering with the download process including AntiVirus Software
Notation: Disabling the AV Software may or may not solve the issue. Removal of the AV Software may increase the chances of the download to perform as expected.
5 - Running behind a VPN which may increase Packet losses or corruption of the download
6 - If via wifi too many Other devices using the wifi at the same time reducing the Bandwidth to your computer.
7 - Best Results are via Ethernet Cable to Router

UpDate or UpGrade ?
These is a very big difference and we need to know which is was.
An update would be from within the current version of macOS Installed on this computer.
An upGrade would be moving from Exiting version of macOS to a Newer Version of macOS.

Upgrade I guess, was running Sierra, tried to install Big Sur
jumping past that many macOSes sometimes causes issues. IMHO, at the very least, you should have upgraded to high sierra before attempting to get to big sur. and if time permits, i would recommend upgrading one at a time from high sierra to mojave, then catalina, and only then upgrade to big sur. it will obviously take a lot of time but at least you will get all of the security components of each of those macOSes.
Question ,did you go to HIGH sierra first? The High Sierra update contains vital firmware upgrades vital to later macOS versions. These problems that are occuring I heard a lot about from people who want to go from Sierra to Catalina or Big Sur when skipping High Sierra.
If your device is compatible with High Sierra, can you boot from a High Sierra bootable usb? And then install High Sierra and after dat preform the Big Sur upgrade?
Upgrade I guess, was running Sierra, tried to install Big Sur
OS update stuck on Less than a minute remaining
