Apple stopped making the 4K Display in 2016, so why do you expect them to have a display still in store in 2019?
I have plenty of need for Apple to repair/replace parts of my 08 Mac Pro and not once did the issue of not having a valid purchase date arise.
From what you are saying, you purchased a 6,1, it developed a fault within a few weeks. Apple replaced this machine. The fault as continued on the replacement 6,1 and has been repaired fixed by Apple?
If the issue has been such a pain, why are you waiting 5 years on to go after them down the Consumer Law route, you should have been doing this 2 years ago the moment AppleCare would have expired. If you have all the paperwork relating to the replacement and repairs to the machine you shoould win the case in court easily.
Apple will see this as nothing more than an attempted to get them to give you a 7,1 for free.
No, as I didn't want to go entirely into the whole backstory.
On delivery of the Mac Pro 6,1 I had a fault (not related to the fault I have had since 2016). Baring in mind this is a system I use for work as a freelance designer. I took the Mac into store and they outright replaced the unit. They had no ability to repair in store.
No issues with the new Mac. At this stage I was using an Apple Cinema Display 30Inch. Through an adapter. IE not using the thunderbolt/display port sockets. Now. baring in mind one of the huge marketing devices with this system was that it could utilise 6 4k displays. ONLY in 2016 when i came to upgrade my display was I made aware of an issue with the display port/thunderbolt. And SINCE then I have been back and forth with Apple. Apart from 8 or so months in-between when I had a family tragedy, and my whole life was paused. Plus the fact that I've had to continue using this system to earn a living.
One of my last visits just this year in February time, I was told they would do an out of warranty repair. BARING in mind they didn't have ANY 4k display in stores to verify the issue. Now, your comment about them selling one is irrelevant. If they are selling a product with external display given they never made one or supplied it with one, they should absolutely have the ability to get one, or have a suitable 4k display to test in store. Anyway, that's not the point.
They were going to repair my system, firstly without seeing the issue I was reporting. BUT more importantly going to carry out a repair, not knowing if it would fix the issue. Baring in mind it's already had two new graphics cards and a new CPU riser and a new PSU. I was told they would be able to do the repair under consumer law. At this stage I didn't care how, but it has a fault so respectfully fix it. When they attempted to put it through on their internal system and only at this point (having sent apple customer service duplicated copies of the invoice both to store and to customer service, it flagged saying "No valid purchase date" because this system was a brand new unit from Apple.
I had 3 years extended warranty, and as soon as I discovered this issue reported it within this warranty. Now I must have been in apple no less that 12 times with this issue. The latest of which required me to take my 32inch display in. Verified there was a problem. Was asked to Pay to repair it. AGAIN no idea if the repair would do anything so apple were willing to take money from me. This is an issue I've reported and have a dialogue about and a case as long as your arm.
My post was to warn anyone who Is purchasing a new Mac Pro, that if apple do replace a unit outright, it may very well affect CONSUMER LAW as that is what I've been pawned off with. I've been told lies outright by the store. Left my display and Mac and told on my return they had fixed it, it was a scaled resolution issue. Outright lie. Got back and it was just the same. All of these visits have come off of technical support calls. So it's been troubleshot by countless supports. It's now with engineering in America, and some customer service here.
I spent 7k on the system. At the time the most expensive system they sold. It's just not good enough.
Also your comment about this being for a free Mac - yeah, I mean there being a clear history since 2016 of issues with it, is me definitely seeing into the future and wanting the new one. What I want is a solution. either a repair which fixes my issue, or a replacement. Even this year when I started back into dealing with it was before any kind of mention before the new Mac was even announced.
If you bought a brand new car, with a sunroof, but told that the sunroof doesn't work, would you be ok with that. And if it went In to be repaired always for the same issue and it never got fixed, what would you do?
