Apple has been with the same Mac Pro for a long time and currently we have little or no indication of possible change except for this little "snitch" that may be the archiving of some pages on the Apple website that refer to the features, specifications and functions of the Mac Pro.
It should be noted that we have not had Not a single change to this Mac Pro since its launch in 2013, so it is to be hoped that soon you can see some movement by Apple for this business sector that is so neglected today in favor of the public sector.
If we look at the past we can see how the rumors about possible renovations or changes resonated in the network during the launch of the OS X El Capitan operating system about ten months ago, but all this has come to nothing and not many users think that Apple is missing an important part of the professional market that seeks powerful computers. Be that as it may, the Mac Pro is at the limit of its life and it needs a change.
On the Apple support website you can see different pages in which the phrase appears "The article is archived and the information is not up to date" and this can be an indicator of change. The change can be for better or for worse since there are no details or rumors firm enough to think that they will change the design of this Mac Pro, but if they can update the ports and other components this year ...
All this while what is expected for sure is a change in the MacBook Pro for this same month of October that is when Apple usually updates their Macs. We will have to be patient and see if Apple really will put aside the professional sector by abandoning (more if possible) or on the contrary it will surprise us with the launch of new Macs next month.
In your experience, if this year they do updates to the Mac Pro, what month would it be for? Otherwise we would have to wait for next year?
