My 3 month old iMac Pro died on March 21st...After weeks in the store for repairs I was told a week ago that Apple decided to replace the machine. One month later, I just got the call today that a replacement machine was at the store for pickup. Am I wrong to expect that Apple should be able to repair or replace a defective machine in less time than a month?...Being without this machine, for this long, has been a huge damage to my business.
You are absolutely correct and I have experienced the same problem. Six weeks after I purchased it, my 10-core Vega 64 2TB iMac Pro starting having thermally-related graphical corruption problems. Apple support said take it to the Genius Bar. They worked on it for three weeks, ordering various replacement parts and finally decided it must be replaced. The estimated replacement time was one month. The total time from malfunction to replacement will be about two months.
Apple's current policy is they don't stock any Configure To Order (CTO) machines, so they cannot quickly replace a CTO machine. In theory they could have loaned me a base iMac Pro or I could have purchased it then returned it within 30 days. However the base machine isn't that much faster on my H264 workflow than the top iMac 27 which I already have.
Imagine a customer who has a brand new $13k 18-core iMac Pro or who next year purchases a $25k top-spec modular Mac Pro, it fails within days, then Apple spends weeks troubleshooting it and an additional month getting a replacement -- a total outage time of two months.
For that class of machine, offering a base model replacement does little good. Apple's current support posture is simply not designed to deal with higher-end professional customers with needs like this. Neither Apple's Business Team or Joint Venture program are equipped to handle this.
There are several issues here:
(1) They seemed unfamiliar with service procedures on the iMac Pro and I was told they had never worked on one before.
(2) Ordering parts for the iMac Pro was delayed. In particular the specialized VHB adhesive tape required for re-assembly was backordered. This is obviously available from some sources else manufacture of the iMP would be impossible. IMO for a Pro machine -- whether that's the iMP or the upcoming modular Mac Pro (which may cost over $20k), all parts ordering should be next-day.
(3) Apple supposedly has no extra CTO iMP machines available anywhere in their manufacturing or distribution system. Other large retailers such as B&H and Adorama have many CTO iMac Pros in stock for immediate delivery but they do not accept returns on Apple products. If other retailers can carry an inventory of professional CTO machines it seems Apple could do this in limited numbers for specialized or urgent support cases.
Apple is investing a lot in the upcoming 2019 Mac Pro, such as having Pro Workflow teams provide feedback during design to ensure it meets the needs of professional customers. The value of this investment will be diluted if commensurate after-sales support is not available. It's a problem for the iMac Pro now and will be an even bigger problem next year for the new Mac Pro.
