Updating MacOS on MacBook Pro (13", mid 2012), 2.5 GHz Intel Core i5, 4 GB 1600 MHz DDR3

I am still running OS X El Capitan 10.11.6 on my mid-2012, 13" MacBook Pro with 2.5GHz Intel Core i5 processor, with 4 GB of RAM. Which MacOS update is best for this model? I am assuming that the latest OS will not be ideal on this model; which OS is the latest I can/should install while still retaining optimal performance? Thanks.

MacBook Pro, OS X 10.11

Installing a newer OS is called an upgrade.


A 2012 MBP can upgrade to macOS Catalina although only having 4GBs of RAM may not

be sufficient for optimal performance.

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

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


For High Sierra, Mojave or Catalina,


Open Safari and click on this link, 

How to get old versions of macOS – Apple Support

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

Then 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.

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 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/ then contact the developers of the software to see

if they are offering 64bit updates.

The Age of this computer will Govern what newer version of macOS it will Qualify to install. Use About this Mac from the Apple Icon on Desktop - the required Information will be there.


With the above information in-hand - follow this How to get old versions of macOS and verify what version this computer Qualifies to install. Make sure to use Only Safari to commence the download as Others may not work


Make a Time Machine Backup Before attempting. Notation - Mojave is the Last version to support 32 bit applications / extensions and Drivers. Catalina Only support 64 bit and there is no workaround.


4 GB RAM will be a push for Catalina as it is more demanding one resources and RAM


Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation
