Do any of the following questions apply to your computer? Any one of them can cause slowdowns andor dodgy computing:

1) Are you running any anti-virus/internet security applications?

2) Are you running any "cleaning/tune-up/optimizations" applications?

3) Any peer-to-peer or torrent downloading software?

4) Any third-party disk backup software that came bundled with an external hard drive?

5) Any online backup scheme other than iCloud (Carbonite; GoogleDrive; MS One Drive)?

6) Did your financial institution ask you to install Trusteer EndPoint Protection (also known as Trusteer Rapport)?

The startup drive is failing, or there is some other internal hardware fault.

Back up all data on the drive immediately if you don't already have a current backup. There are ways to back up a computer that isn't fully functional—ask if you need guidance.

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

Keeping your confidential data secure during hardware repair

Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

*An SSD doesn't need to be zeroed.

Thank you very much!! All my data is backed up so no worries there.

I will run the repair and see if that helps. 🙂

Thank you very much!

Your hard drive is failing, and will need to be replaced. Contact Apple for assistance with that if you're not sure how to replace a hard drive yourself.

Since the drive is failing, and could take your data with it at any time, make sure that you back up your data immediately!
