Hope this is the right place to ask this.

I am running the latest Sierra version on a miniMac with 8 g of memory.
For some reason I cannot figure out, for the last week or so the computer is really slow opening apps. For instance, Safari is taking 1 minute +/- to open.

Anyone has an idea on this?

Thanks.

The first thing that comes to mind is that the Hard drive is starting to fail. And if that's it, you will need a backup to get it restored, so I hope you are making backups regularly.

In addition to what Jake mentioned. Check to see how full the hard drive is. A near full HD will slow things down.

Thanks for taking the time to respond to my problem. I am not real sure how you do what you suggest. I have my computer backed up to an external drive using Time Machine. I am guessing I just have to google "restore hard drive" to see what to do.

Thanks again.

Thanks for the reply. I will see how to check my HD. Maybe Utilities?

I meant that if (when) that drive fails you will need to get a new one, and then to restore from the backup. Restoring a failing drive won't help the failing drive at all. Failures are usually hardware and permanent.

Disk Utility can check the drive and do some repair, but it won't always uncover pending failures. Some functions are performed by the drive hardware itself, like retries of read/write operations. All DU checks for is ultimate success, not the number of tries it took, so if a drive is marginal and each read/write has to be repeated multiple times before succeeding, the DU check will come back as successful, which is true because it did succeed, but in fact the drive is failing because it took so many retries. If the drive is S.M.A.R.T. enabled, a SMART checker may be able to give you some idea of performance.
