My Macbook Pro is having a problem with the mouse pad. Long term I'll probably will have to open it up & clean it up.
Not really an urgent problem since I am currently using a wireless logitech M510 mouse as a work around. You can get one from Amazon.
I seldom use the mouse in Macbook's....whether macbook, pro or..... each unit I buy usually come bundled with free wireless mouse, I have a collection of unopened wireless computer mice, plus a few free Magic mouse in their box unopened...I only have one Magic Mouse opened to test some Mac games...other than that, I use the track pad. That's the reason why I switched over to MAC...no need to remember to bring along my, trackball mouse, later my wireless mouse whenever I have to bring my notebook computer out.
Be careful about the track pad area...area better get it checked ASAP....let me relate my experience, I have a Macbook pro, bought new, this unit is a few generation back from current,it became a battered 'old horse'....insides all working fine, cover has plenty of dents ( was use travelling extensively, not by me though), the headphone port spoiled, I replaced it for $80....the battery charging unit conked out & later a new macbook was bought to replace the 'old horse' for it was an emergency & urgent work needed to be completed quickly. ( not me though)
After a new unit was purchased, he Macbook pro was left in storage for some time ( almost 2 years), I took it out sent in for checking & servicing & it was found to be working fine, a little slow...but still good; was meaning to give this to some deserving children in some less well off country...left it aside for another year, forgot all about it...then recent months toolkit out for a look, found out the track pad area buckled upwards & cracked open. I brought to the repair shop, they told me, its a common problem, the battery inside expanded....the cost of replacing the battery etc...might as well buy a new one...anyway, I sold the unit for $60.
My point is....do send the unit for a check...don't one day.."surprise!"..
