How should I update my Mac which is Yosemite?

How do I update my Mac?

Info:

OS X Yosemite

Version: 10.10.5

MacBook Pro ( Late 2008):

I've tried various methods like these but it didn't work:

By the way, I need answers quickly as this mac will soon not support every app I have on here.


Thank You!

A MacBook Pro from 2008 can only upgrade as far as Mac OS X El Capitan 10.11.6.


Open your Safari browser and click on the link below,

https://support.apple.com/en-us/HT211683

Go to Use Safari to download….. and click on OS X El Capitan 10.11

this downloads InstallMacOSX.dmg to your Downloads folder.


The next section can only be done on a mac that is capable of running El Capitan.

This includes macs that have the potential to run El Capitan but have been upgraded to a newer OS.

A mac that came preinstalled with an OS later than El Capitan will refuse to do the next bit.


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 InstallMacOSX.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.
