On Monday, Apple released GM (Golden Master) of OS X Mountaion Lion to developers, that is to say it will soon reach Mac customers (for $19.99 Mac upgrade). The on-sale date for Mountain Lion GM is probably between two and three weeks away.
So far, the only official word from Apple is that Mountain Lion will hit the Mac App Store this month. According to the company’s past practice (like last year’s surprise announcement at an earnings call that Lion would launch the next day), and with that quarterly call slated for July 24 this year.
We’re hearing from people who have installed the Golden Master that GM is smoother. Specifically, Dictation’s overall performance is stated to also be improved.
The GM build is almost the same build that is released to the general public, which means Mountain Lion is now considered “ready to ship” by Apple. After it goes on sale to the public, customers running Snow Leopard or Lion can upgrade to the new edition, which will be priced at $19.99, a 33% discount when compared to 2011′s Lion.
