macOS (OS X) Installation on Mac

When the system is weighed down by years of apps, or will not start at all, a proper clean macOS install brings back the speed your Mac had on day one.

Installing macOS on a Mac

When a reinstall makes sense

  • The Mac stalls on the Apple logo or shows a folder with a question mark
  • Apps quit unexpectedly and macOS updates keep failing
  • The computer has become very slow for no obvious reason
  • You replaced the drive or want to sell or hand down the Mac

What we do

First we back up your documents, photos and settings. Then we format the drive and install the newest macOS your model supports, or a specific version if your work software needs it.

Afterwards we restore your files, set up Wi‑Fi, printer and iCloud, and test that everything works. If the real cause is a failing drive we will tell you and suggest an SSD replacement.

Just want a newer version without wiping anything? See macOS upgrade.

Frequently asked questions

Which macOS version can my Mac run?

It depends on the model year. Tell us your model or bring the Mac in and we will recommend the best compatible version.

How long does it take?

Usually the same or next working day, depending on how much data needs to be moved.
