I can't update my macbook air of 2015 from OS X Yosemite 10.10.5 to OS Big Sur

I have a MacBook Air from early 2015 with the OS X Yosemite 10.10.5 update and I am trying to update it. The app store doesn't show any updates and neither the system preferences.

Did anyone have the same problem and managed to solve it?


MacBook Air 13″, macOS 10.15

Back up your data, check your applications for compatibility, and click on El Capitan, High Sierra, Mojave, Catalina, Big Sur, or Monterey. They're full-version upgrades and won't appear in the Updates list.

The App Store Updates page only informs you of updates available for the OS you are running.


Installing a newer OS is called an upgrade.


A MacBook Air fro 2015 can upgrade to all available OS's.

As your mac can upgrade to the newer OS's like macOS Mojave 10.14, macOS Catalina 10.15, 

macOs Big Sur 11.6 or the latest macOS Monterey 12.0 I would recommend you upgrade to 

macOS High Sierra 10.13 first.


For High Sierra, Mojave, Catalina or Big Sur,


Open Safari and click on this link, 

How to get older versions of macOS

Go to Check Compatibility to see if your mac qualifies for the OS upgrade you want.

Then go to the Use Safari to download macOS section and click on the OS you want to install.


Before upgrading make a full back up of your Mac.


Check that third party apps you use have updates available for the new OS.

https://roaringapps.com

Check that your printers/ scanners etc have updated drivers and software available for the new OS.


Connect your mac to your router via cable rather than rely on WiFi.

Do not use your mac while it is downloading

and do not use any other devices that share the same internet connection.


If the App Store says ‘Open’ then it is detecting a previous download of the install app

go to the Applications folder locate Install macOS ******.app.

Move it to the Trash, empty the Trash.

Restart, click on the link again, the App Store should say ‘Get' or 'Download'.


If you want to or are able to upgrade to Monterey open Safari and click on the link below,

How to upgrade to macOS Monterey – Apple Support (UK)


If you are considering upgrading to Catalina, Big Sur or Monterey be warned they do not support 32bit apps.

Your Mac is probably running 32bit apps and these will need to be updated to 64bit apps,

some updates may be free, some may be paid. Use this free app to discover which apps you have

are 32bit, https://www.stclairsoft.com/Go64/ then contact the developers of the software to see

if they are offering 64bit updates.
