OS X Mavericks brings numerous improvements and additions and the expectation is that a launch is imminent. Details of the software have already been revealed so of most interest will be the price. Apple's update to Mountain Lion, the current desktop OS, cost US$19.99 so users are expecting a comparable price.
Apple unveiled the Mac Pro computer under glass at its WWDC developer event earlier this year, but it's still not on sale. On Tuesday, Apple could provide a launch date and price for the computer, which represents a radical redesign from previous models. The computer is circular with a hole running vertically through the middle to allow for better airflow.
Of most interest to professionals is the price. Power users are already asked to pay at least $2,499 for a Mac Pro so many are hoping the base-level model doesn't end up costing even more.
And new MacBook Pros?
Intel's latest laptop processor, called Haswell, was added to the MacBook Air lineup earlier this year but has yet to appear on the meatier MacBook Pro computers. Haswell is now appearing in many competing laptops and an update of the Pro line to include the chip seems like a natural step.
There's a chance the Pro computers could be revised with the higher resolution "Retina" screen become standard across the product range. Reducing prices for laptop screens would make that easier for Apple to accomplish with little or no price hike.
One More Thing
Could Apple surprise with the unveiling of either of its most talked about phantom products: a new Apple TV set-top box or an iWatch wearable computer and phone?
There are few people expecting either of these to be launched Tuesday. It might be partly because such products could command their own announcement events and because there have been few advance leaks about the anticipated products.
