Thanks again - Allan Jones for your comments. I'm a little confused by the Huawei phone comment as Ive never had a Huawei phone....? Can I delete this software somehow?

Also regarding the external drive, I use a TimeMachine backup to external hard drive, so I guess that means I can get rid of the Seagate Software?

My photo stream from my iPhone does upload automatically to my iPhotos... but I would be surprised if that's using all the GB (some days the computer runs up over 10GB of usage when Im just emails and browsing!)

Thank you again - so helpful and kind of you to give your time and advise me.

Thank you so much for your response... but what are 'swaps'? Apologies for my tech- ignorance!

Everyone - thank you! What a great amount of response, never expected such detail and much appreciated - I will go into the list and see what works.....
