Apple has updated the iMac Pro webpage, indicating that the machine will be for sale on Thursday, December 14.
Some hands-on coverage is surfacing this morning, including this video by MKBHD. In it, he mentions the 18-core option won’t ship until early 2018. There’s also a previously-unannounced 14-core model.
I’m extremely interested in this machine. I’m going to let the dust settle a little bit, but at this point, am really considering picking one up early next year.
