any one can help to fix it ? i tried to upload the software in many ways go to apple Store or allow auto updating ..none is working..
MacBook Air 13″, macOS 10.15
How is the Empty Space Available situation on the Internal Drive. Pay Special Attention on requirements. Also, any third party AntiVirus, Optimizers, Cleaners etc installed. None of them are needed on macOS and will make modifications to the system causing all sorts of undesirable results up to corruption of the OS.
Yes try again for the Apple Store but first check if your drive is using FileVault. If so, temporary Turn it Off. It can be Enables after a successful Big Sur UpGrade.
My personal experience on Retina MBA 2018 with T2 chip. Made a Bootable Installer of Big Sur. Got in to Recovery Mode and enabled booting from External Drive ( T2 Chip by default does not allow). Booted from Installer. Immediately, received Notice from Apple Servers " that an Update was Required to continue to use this disk." Allow it to do, computer rebooted to USB Installer and all when fine. The Point being, after Big Sur was installed, discovered the Notice about continue to use this disc was Actually BOOT ROM Upgrade required to install and use Big Sur.
Would suggest contacting Apple Support directly ( Phone or Live Chat ) and / or via Feedback.. Their System Status is showing all systems are working.
Reading many others have similar issues on relatively newer Apple Laptops of various Models and years. Have read where MacBookPro 2013 and 2014 are being denied the UpGrade to Big Sur or if installed has borked their computers. Very limited issues of similar type for MBAs though except where Empty Space Requirements are not met.
tried one more time now get the error message as below
i will try again downloading from apple store ..but i did it before and the security setting was still allowing from apple store download. what is the gatekeeper policy ? from the web i just got messages of people having the same problem that i have
disabled FileVault ..
tried Terminal and got no update available ..then downloaded it again and got the error message below
did not try the bootable installer option i may not be good to make this work ..i disabled the automatic update but as soon as the download is completed apparently start the auto installation and stops by errors..
many thanks
One more thing, Open Terminal and type in " softwareupdate -l " without the quotation marks. It should list all available updates including the Big Sur UpGrade. If it does not, it maybe an issue with Apple Servers.
I am having the same issue as described above. I did have anti virus on it for a brief time (I did not realize I did not need it). I did not install it back on for quite some time but do you think I could have corrupted my hard drive? How do you go about fixing this issue? I should mention I reset and erased all memory on my laptop because I am giving it to someone else. When I try to reinstall macOS I get error messages saying there was no software found to install it.
Usually, I do not response to a New Topic in the same thread but see you have attempted n Erase and Install. By what method? Was it via Recovery Mode? Have you attempted using Internal recovery Mode ( Command + Option and r ) immediately at Boot up.
I wish to thank everyone, finally using the internal recovery mode, i was able to download and install iOS Big Sur on my Mac Book
great help!
P. Phillips thanks that screen shot from my mac..should be okay ..but still have problem
I’m so sorry! Yes it was via recovery mode. I used the command + option and R. I get the message OS X could not be installed. No packages were eligible for install.
The method you describe is Internal Recovery and will Require a reliable, stable and fast Internet Connection for it to work.
i have a Mac book air 13 -inch early 2015 running MAC OS Catalina 10.15.7 i keep receiving the update request to Mac OS Big Sur and have downloaded the update at least 10 times but always receive an error that installation cannot be completed
