I worked so many overtime hours for just one purpose.*to buy a new Mac. This is going to be a work machine. 1. Air or Pro ? 2. Used or refurb ? 3. Or just search for the best new deal? 4. My budget is $1000 5. As a Chef I have to use EXcel 6. Also my company uses software that only works on internet explorer so I will have to use Bootcamp or a VM machine. 7. Overtime hours on a 55 year old are very hard all help will be greatly appreciated,please and thank you.
