Late 2013 27” iMac: how long will it be supported?
Posted by: Ammo
Date: November 24, 2020 05:26PM
I realize it won’t be able to run Big Sur, but does anyone have a guess about how long will I be able to get Catalina updates? I’m especially concerned about security updates.

I’ve been advised how to upgrade the processor and memory for a reasonable amount of money, but wonder if that’s worth it or if I should consider switching to an M1 Mini to use with my current monitor.

When has it ever been possible to upgrade the processor on an iMac?

I think the last Macs with upgrade-able CPUs were the G4 towers...I believe.

2013 Mac Pros (Trash Cans) have upgradeable CPUs. I just upgraded two of them to 8-core (from 4 and 6 cores) during the pandemic.

I agree. For example, Apple just released a security update to High Sierra a couple weeks ago. High Sierra was first released in 2017.

Some of the iMacs have upgradeable CPUs, if you're willing to disassemble the entire thing...

Ah, let's use 10.12 Sierra as an example.

Released: 9/20/16
Last Update: 9/26/19
End of Life (no more updates): 11/30/19.

Catalina was released 10/7/19, so we could assume it'll be updated until at least October 2022. High Sierra is rumored to EOL in January, which would be a little over 3 years of support.

My mistake - ugrading memory and booting off external drive is alleged to speed up operations considerably.

I think Catalina may have a little extra life in it, but I would not count on more than 3 years.

That iMac will be enhanced by an SSD external boot drive.

Apple releases content and security updates for the current year's Mac OS. They release security updates for the previous 2 versions of the Mac OS.

So assuming an Autumn release for the next 2 OSes, which has been the pattern for a decade now, OS 10.15 Catalina will receive 2 more years of Security Updates.

A number of the iMacs have socketed CPU chips, for example my 2009 iMac has one. Getting in is involved, just as any work is inside an iMac. Have not checked on the 2013 model as to whether it has a socketed CPU.

If you want a new machine, go ahead. Your current machine likely works as well as it ever had. It has years left. You'll know when its time.

I did that to an old (86yo)/friend/client's full spec i7 CTO '13 iMac awhile back, and he hasn't stopped singing the iMac/SSD's praises ever since. I splurged and got a new set of Velcro rolls to secure the SSD to the back of the iMac.... only to find the old rolls about three weeks later, so now we're rollin' in Velcro. For an oldster, he beats on that iMac with the reckless abandon of four millennials, so the setup has earned its stripes. If you haven't SSD'ed yours yet, it's a trip worth taking, and enjoying.

Macs with Intel processors should be supported for 4 years after the last one is removed from the Apple store.

The best part of owning a Mac is how long/far Apple's support goes both in terms of new OS options and, even after that's done.... important updates for OS versions prior.

We have media & entertainment customers that won't or can't go past 10.12.x yet.... buying new Mac Pro 2013s for their work flow teams. When a work flow works, it's a slow process to move forward and good reason needed as why break what's already working great?
