Hi,
I have iMac late 2012 (CPU i5 2,7 GHz, RAM 8GB, HDD 1TB 5400) and OS X El Capitan. For all the time I did not do a clean install of system.
In last months I have problem with smoothness of system. System very offten (every 1-10 minutes) loading. In "loading mode" are:
- mouse cursor is rolling
- music from iTunes stop play for a while
- video in VLC stop play for a while
- I can do nothing at this time
Please, where could be a problem? I think that one of these things:
- SW problem in OS X - solution maybe will be clean install of OS X
- HW problem - HDD or RAM
Is it some way to find it (some good diagnostic tools or etc.)?
Thank you.
iMac (21.5-inch, Late 2012), OS X El Capitan (10.11.6)
