2010 imac running el capital?

[macca1980]

I saw a 2010 imac i3 for sale running el capitan... This is a selling point in the ad.

Does the latest osx not make it more laggy and slow on older machines?

Spare your money to replace the hard drive with SSD. The rest should be fine. Otherwise, you should go up to Mountain Lion (or Mavericks if you can tolerate more for slowness). I used ML for my 2010 iMac.

I have it running on a 2010 I7 IMac here. Runs fine from what I've seen.

I'm running Yosemite on a 2010 3.06 C2D iMac it still runs great with Win 7 on Parallels. It did bog down a little before I put 8 gig of memory in but now no problem.

I've been running El Capitan through all the betas, on an Early 2008 iMac. It runs as well as or better than Yosemite, Mavericks, or Mountain Lion did (for me) - I can't remember much farther back than that. It's taken some work, because older machines can take some work.

If the seller has done the right thing (erase HDD and reinstall a clean version of OS X) the machine can be performing very, very well. You'll be starting from a clean User account, as well. That means your system won't be laboring under layer upon layer of "history" - all the stuff that builds up as you use the system and upgrade software. Rolling back to an older version of OS X is not likely to improve the performance under these conditions.

I have the same iMac - 2010 i3 iMac. I have upgraded to 8GB, and most importantly installed a Samsung 850 EVO SSD. I run El Capitan. It runs great and does everything I could ask of it. OS X is not like Windows and in my experience the latest OS can run well even on older machines.

I have a very old iMac (Mid 2007) with a 2.4GHz Core 2 Duo running 10.11.4.
Definitely not the fastest box in the shed, but not lagging issues.
And Yes, I do know it's way past time to replace it, but the SSD drive breathed a wee bit more life out of it.

Sure very easy, go to OWC site and watch their video.
