Can't update beyond Yosemite 10.10.05

Hello,


I have a MacBook Air (13-inch, Early 2015), and need to update my software to at least El Capitan for an editing app I need. I have enough storage on my computer, and there's seemingly nothing 'wrong' going on. I go through the whole process until my computer restarts. When my computer restarts, it's still on Yosemite. There's no apparent reason this should be happening. I've re-downloaded El Capitan and gone through the whole installation process ten times, but once my computer starts back up it's still on Yosemite. Does anybody know what I can do??

MacBook Air 13″, macOS 10.15

If you do have an operating system on your mac and it is functioning then you can download

El Capitan using this method.


How to upgrade to OS X El Capitan – Apple Support


Go to Section 4 and click on Download OS X El Capitan.


This downloads InstallMacOSX.dmg to your Downloads folder.


When downloaded open to InstallMacOSX.pkg, double-click on

that and an installation window will open, this does not install El Capitan

but converts the .pkg to the Install OS X El Capitan.app which you will find in 

your Applications folder, it should be 6.2GBs in size. 

If the installation window asks which disk you want to install to, you must pick 

the disk that you are booted to at the time. Not any internal or external disk that 

you want to eventually install El Capitan on, that is for later.


To start the installation of El Capitan double click on the Install OS X El Capitan.app.


The copy of the install app self deletes after installing El Capitan, so make sure you keep a copy of the InstallMacOSX.dmg

if you need it in future, or you could just make a copy of the Install OS X El Capitan.app prior to installing and moving it to

an external drive for safe keeping. It is also possible to create a bootable USB installer disk, using the Install OS X El Capitan.app

in the Applications folder, and the createinstallmedia command in the Terminal app.

The model and year of your Mac will determine which macOS you can upgrade to,

please use Safari to access the following links do not use Firefox

How to upgrade to macOS High Sierra - Apple Support


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 are considering upgrading to Catalina be warned that it does 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 app to discover which apps you have

are 32bit, https://www.stclairsoft.com/Go64/. Once the list has been created you can then

contact the developers of the apps to see if they provide 64bit updates.
