iMac 2013 update OS

Hello - my iMac is from 2013 and had yosemite 10.10.5 on it. It's causing a lot problems where I can't access different browsers, I can't download because it is not compatible etc. Does anyone know how I can upgrade to a later version or which version is compatible? Thank you!

A 2013 iMac can upgrade to the newer OS's like macOS Mojave 10.14 or macOS Catalina 10.15, 

I would recommend you upgrade to macOS High Sierra 10.13 first.


For High Sierra, Mojave,Catalina,


Open Safari and click on this link, 

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

Go to the Download OS 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.

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 tit 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 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.
