I gave a 13-year-old iMac new life with two simple upgrades, but was it worth it?
Nostalgia for technology is all the rage right now. Whether it’s film cameras making a comeback, CDs making a comeback, or flip phones dominating the headlines, old technology has somehow become popular again.
I’m also not immune to the nostalgia bug, but instead of buying something new, I decided to set myself the task of giving a new life to a 2013 Apple iMac.
This particular 27-inch model had been collecting dust, but with its generous screen and functional hardware, throwing it away seemed like a terrible waste. Especially when a new 24-inch M4-powered iMac would cost me over AU$2,000. With a little research and DIY know-how, you could get the older 27-inch model working again for less than AU$500.

My ambitions were relatively modest: I wanted something capable of web browsing, some light creative work, and other basic daily tasks. I didn’t expect it to compete with my M2 MacBook Air.
After some research, I settled on two relatively simple upgrades: more RAM and a new 1TB solid-state drive (SSD). And for a total outlay of around AU$310, I was hoping I could give this old Mac a fighting chance.
Two upgrades, one old iMac
The first thing I needed to address was storage. My iMac originally came with a mechanical hard drive, which is not a recipe for fast performance in 2026.
Swapping out an old hard drive for an SSD is often one of the most effective ways to breathe new life into an old computer. With no moving parts and significantly faster data access, an SSD can improve everything from boot times to opening apps.
My original plan was to replace the internal drive entirely, but that presented a bit of a problem. Unlike some previous iMac models, my late 2013 version has a screen attached to the chassis with adhesive. Getting inside requires cutting that adhesive, carefully lifting the screen, and disconnecting the cables before even thinking about accessing the unit.
I’d never attempted anything remotely like this before, and the thought of potentially damaging a perfectly good 27-inch screen wasn’t particularly appealing. Fortunately, there was an alternative: an external SSD.
Instead of dismantling the computer, you could connect a 1TB TeamGroup T-Force Vulcan Z SSD via USB, install a later macOS on it, and use it as a boot drive. It’s a considerably less intimidating approach, even if the iMac’s older USB 3.0 port meant you wouldn’t get the full performance potential of a modern SSD.
The second upgrade, the RAM, was comparatively easier as Apple made upgrading the RAM on this generation of iMac remarkably easy. A small access panel on the back of the computer provides access to four memory slots, meaning you don’t need to disassemble anything to install additional modules.
My iMac originally had 8GB of RAM, and adding two 8GB Timetec DDR3 drives brought the total to a fairly generous 24GB. I don’t claim to be a computer hardware expert, but even I knew it would provide much more breathing room for multitasking than the original setup.
I admit, I wouldn’t have known where to start without a little help from ChatGPT. He walked me through choosing compatible components and, more importantly, the process of installing macOS Sonoma on a computer that doesn’t officially support it.
Instead of spending hours browsing forums, I could explain exactly what I was seeing on the screen and get advice on what to try next. It wasn’t entirely easy, but having something to fall back on every time I hit a roadblock made the whole process a lot less daunting. Although, as my colleague discovered when he asked ChatGPT and Gemini to help him build a gaming PC, AI assistance doesn’t always guarantee a stress-free experience.
How much did everything cost?
I’m well aware of the current RAM crisis affecting the tech industry, so my immediate thought was that purchasing additional memory could make this project more expensive.
Fortunately, it turns out that no one running an AI data center is particularly interested in 13-year-old DDR3.
A quick search on Amazon revealed a pair of compatible 8GB RAM modules for around AU$70, while a 1TB SSD was just under AU$230. Those are the components taken care of for AU$300. Add in a Ugreen external SSD enclosure (I paid AU$17) and, taking into account some Amazon promotions at the time of ordering, my total spend was about AU$310.
That’s considerably less than buying a new iMac, of course, but it’s still a reasonable amount of money to invest in a computer that’s more than a decade old. And while I was quietly optimistic, I was also aware that adding RAM and an SSD to an old Intel processor wouldn’t magically turn it into a modern Mac.
There was only one way to know if you had made a wise investment.
So how does it work?
With the updates completed and macOS Sonoma installed, I finally had a functional iMac on my desk. But getting an old computer to boot is one thing. Making it truly useful in 2026 is another.
My first test was to see how long it took to start. From pressing the power button to reaching the desktop, I recorded a time of 1 minute and 52 seconds.
I admit, I expected better. I’m used to the near-instant responsiveness of my MacBook Air M2, so waiting almost two minutes for a computer to boot up seems like a small eternity.
Of course, there are some mitigating factors. This is still a 2013 machine powered by a 3.2GHz quad-core Intel Core i5 processor and boots macOS from an external SSD via USB 3.0 rather than a faster internal connection.
It’s also worth noting that I didn’t record performance benchmarks before upgrading the hardware, so I can’t offer definitive figures showing how fast the machine has become.
Fortunately, things improved once I started using it. Basic web browsing turned out perfectly fine, pages loaded correctly, and the overall experience remained usable, albeit with occasional lags. I was particularly interested to see how Canva would handle, as I occasionally use the browser-based design platform for light creative work.
And, to my surprise, it worked. I opened Canva in the middle of the 27-inch screen, with the TechRadar YouTube channel running in another browser window next to it. I was able to work on a simple design while keeping the website open, although there was some noticeable slowness.
It’s certainly not an experience I’d prefer over a modern Mac, but it shows that this old machine still has something to offer.
The screen is another highlight. With its 2560 x 1440 resolution, the 27-inch panel still offers plenty of screen real estate, and being able to arrange multiple windows side by side is something I particularly appreciate.
Sure, it doesn’t have the sharpness or brightness of Apple’s newer displays, but that doesn’t automatically make it unpleasant to use.
And there’s something quite satisfying about seeing an old computer performing tasks that, not long ago, you weren’t entirely convinced it was capable of.
There are still big commitments
Of course, the amount of new storage and additional memory you can get is limited. The processor and graphics hardware are still over a decade old, and while upgrading them isn’t entirely impossible, doing so would require a much more involved teardown process. Given the relatively modest tasks I had in mind, it was a level of effort and expense I was not prepared to take on.
Then there is the question of software compatibility. My late 2013 iMac officially supports macOS Catalina at most, but I managed to run macOS Sonoma using an unofficial installation method.
While this gives me access to a much newer operating system, it’s not an officially supported setup and that brings potential complications around security updates, drivers, and long-term reliability.
Was it worth the money?
So would I recommend spending a few hundred dollars to upgrade a 13-year-old iMac?
Well, that depends. If you’re hoping to turn an old Intel Mac into something that feels as fast and responsive as a modern Apple silicon machine, you’ll probably be disappointed, unless you’re working with a relatively newer model than my machine.
My nearly two-minute boot time alone is evidence that upgrading storage and RAM hasn’t miraculously solved all the performance issues. And while web browsing and Canva are perfectly usable, there are enough occasional lags to remind me that this is not a computer I’d want to rely on for demanding work.
But that was never really the point of the exercise. I already have a MacBook Air M2 that I turn to for my daily computing needs. What I wanted was to see if I could rescue an old iMac and give it a second life, rather than letting it become part of our growing e-waste problem.
And on that front, I would consider the experiment a success. I now have a functional 27-inch desktop computer that can browse the web, perform simple creative tasks, and provide a decent amount of screen real estate, all without having to buy a whole new computer.
Honestly, if you have an old computer collecting dust, it might be worth investigating whether it still has some life left in it. But don’t expect it to be as fast as you remember.
