iMac 2017 running slow

NEVER EVER install the following types of third party apps unless you want a slow, unstable, and troublesome Mac:

·      Antivirus Apps

·      Cleaning Apps

·      Security Apps

·      VPN Apps

·      Maintenance Apps

These types of apps do absolutely nothing that Mac OS cannot already do. All Mac OS needs in order to remain secure, stable and fast is simply to keep it up-to-date and to restart the computer about 1x per week.

A great tool for looking is EtreCheckPro.

That is fine, however you may have a problem you are not aware of. I would strongly recommend the following:

You’ll experience some slow downs with older machines, but there are options to speed things up. Certain software like CleanMyMacX are great for what you need, although they cost a little bit of money. If you back up all the files you need and wipe your Mac, a fresh install of MacOS goes a long way. This does take time, however.

Many thanks. I think I'll keep it simple and push on. It's a great machine just getting a bit slow that's all.

You're welcome. Let us know if you need help with anything in the EtreCheckPro report.

Regardless of what you think about CleanMyMacX...

It is always best to look for the reason, instead downloading and using any kind of third-party clean app.

Thanks for chiming in rk87... 👍

Of course!
