How can I upgrade an old iMac running Catalina 10.15.7?

What to do with an old 2013 iMac?

Its a nice old thing but slow and can't be updated so do I chuck it out?

I'm running Catalina 10.15.7

I can't afford to buy a new one yet though

Startup Drive


If your Mac has a mechanical hard disk, one thing you could do to speed up startup and application launches would be to get an external USB 3.* SSD, clone your current system to it, and make it your startup disk.


Because your Mac has old-style Thunderbolt 1 ports that use Mini DisplayPort connectors and that run at "only" 10 Gbps, it would not be practical to connect a modern Thunderbolt 3 or Thunderbolt 4 SSD. But even a good USB 3 SSD would run rings around a mechanical hard drive,



RAM


If you have at least 8 GB of RAM now, a lack of RAM probably is not the cause of your slowness problem. Still, your Mac has user-expandable RAM and can take up to 32 GB. There are some cases (e.g., heavy Photoshop workloads, running virtual machines) where having more than 8 GB could make a significant difference.



Software


Microsoft and Adobe have a policy of supporting only the most recent three versions of macOS. Catalina is not one. Catalina is good enough to run the current versions of

  • Firefox
  • LibreOffice
  • The GNU Image Manipulation Program (GIMP)
  • The commercial Affinity V2 programs (Photo, Designer, Publisher)

FWIW, I have been using Mac minis since 2006 and have never regretted it.


Since your budget is in consideration, you can get them at a much discounted price by going to either:


I would suggest not going with anything older than the Late 2014 model, with the Late 2018 model a better choice as it supports the latest macOS version (Sequoia).

Thanks for that.

I did think of getting a Mini M2 and use the 27” iMac as screen only, which would speed things up a bit.

Don’t know much about the Minis it just seems like a very good idea having a small box like that as apposed to the old PC boxes I used to have.

Like everything in life it’s all based on finances and now I’m retired I’m not as rich as I used to be!

The 24” iMac aren’t that much smaller than the 27” so maybe get one of those. Decisions decisions !!
