It sounds like you may still have some supporting files from ibackup on your system. Please download and run Etrecheck  It is a diagnostic tool that's very useful to us in finding problems. Also it will give us further specs on your Mac. After it runs post the log file here. It will contain no personal information.

To post the log file click on share report and use the Page icon in your reply window. See video:

Install an OS preferably High Sierra onto an SSD external disk.

Get macOS High Sierra.

Then boot from it and test with just the default install. (That will tell if it's your internal HDD or possibly another piece of hardware at fault) If that works well then install only the third party applications you need. For then on you can work off that external drive. And when you do replace the Mac, you have a fast external hard drive for your new one.

I did try clicking on Clean Up but I'm not sure what I'm suppose to see happen. Should I run the test again and see if the orphaned items are still there?

Sure, you can Etrecheck as many times as you like.

maybe I should install ibackup and follow the official uninstall instructions as Eric suggested (if I ever had it installed I would have used AppDelete to remove it but perhaps something got left behind.)

Can't hurt.

FWIW I'm running on a 2010 iMac myself. It's the 27". Only difference is the 7200 rpm drive vs. the 4500 yours has. It still runs as fast as the day I got it, still on the original 7200 rpm spinner. If the hard drive goes I plan to replace it with an external SSD and run from that. I'm hoping to get another couple of years out of it, vintage or not.

If you want to try macjack's suggestion, I have purchased RAM several times, a MacBook Pro battery, and 2 hard drives from Other World Computing and have always been very satisfied with the product and service.

23 minutes is a horribly long runtime for Etrecheck and you certainly have a lot of junk on there. I'd suspect a failing hard drive although Etrecheck isn't reporting that.

If it was my Mac I'd do a clean install to an external hard drive and test. It that runs as expected they you can begin adding back just the applications you need. When it's all set up clone it back to your internal. Or you can purchase and external SSD for the purpose, which would give you a dramatic increase in speed and just continue to run from the external drive.

If you want to clean up yours for openers you can click on Clean Up from within Etrecheck to remove the orphaned items under the Clean Up heading.

I do see a couple of different backups references but I don't if they belong to ibackup or not.
