Preventative ...

You do not run your car until it breaks down you get it serviced regularly to avoid being stranded at the most inopportune moment. Regular checks prevent the same happening to your Mac. There are many small processes you can undertake on a daily, weekly or monthly basis to help keep your Mac up, and your support bill down. Ask us next time we are with you. Alternatively we can do these chores for you on a regular basis as part of a support package. Or just when you have the time.
