macOS Support & Security Updates

How Long Does macOS Support Last?

We often get asked how long an Apple Mac will receive support - and the good news is, a long time!

Most Macs receive at least 7 years of major operating system updates. Even after that, Apple continues providing security updates to keep your device protected.


With the release of macOS Sequoia, Apple dropped security support for Monterey, meaning some older Macs are no longer receiving updates. Here’s how long these models were supported to give you an idea of longevity:

  • iMac 2015 – 9 years

  • MacBook Air 2015 & 2017 – 9 & 7 years

  • MacBook Pro 2015 & 2016 – 9 & 8 years

  • Mac mini 2014 – 10 years

  • Mac Pro 2013 – 11 years

  • MacBook 2016 – 8 years

We expect at least 8 years of support for most models, and with the transition to Apple Silicon (all models from 2020 onwards), support windows are likely to extend even further!


What Happens After macOS Updates Stop?


Once security updates end, you can still use your Mac, especially for general tasks like web browsing, emails, streaming, and homework. Microsoft Office 365, for example, still runs on macOS Catalina (released in 2019). If you purchased a MacBook Air 2012 for example so far you've had 13 years of application support!


If you’re dealing with sensitive data, we recommend upgrading to a newer model to stay fully protected.


How to Keep Your Mac in Great Shape


A well-maintained Mac can last well beyond software support! Here’s how to keep yours running smoothly:


Screen Care


✅ Use a microfiber cloth and avoid harsh chemicals like ammonia or alcohol when you clean.

✅ Always remove dust or crumbs before closing the screen.

✅ Use a microfiber protector when closing your MacBook to prevent wear.


Chassis & Keyboard Care


✅ Avoid stickers and hard-shell cases—they can discolor the metal.

✅ Store in a soft case or sleeve for protection.

✅ Clean your keyboard with a microfiber cloth and apply cleaner to the cloth, not directly on the device.


Port & Ventilation Maintenance


✅ Use canned air or a cotton swab to clean ports

✅ Avoid dusty environments and smoking near your Mac - clogged fans lead to overheating


Battery Care


At MacFinder, we replace any battery with a service light in the first year for free.


To extend battery life:

✅ Don’t keep your Mac plugged in 24/7

✅ Avoid excessive heat exposure

✅ Follow Apple’s battery optimisation tips
