According to AppleTrack.org, there is a shortage of many different Mac models. Some shipping dates are slipping into December. It the case for the 21.5” iMac and iMac Pro. Troubling.
When Apple announced they were transitioning their Macs to use the new Apple Silicon, they also said they would keep updating current Intel-based models for a while. I don’t know this will translate in reality. If the iMac Pro is being updated this month, it could be for an updated configuration with an Intel CPU, not an Apple Silicon. The case of the 21.5” iMac is more interesting, tough. The 27” iMac was updated recently but not the 21.5. I’m not sure it is the first prime candidate for the Apple Silicon. I’m thinking more about the MacBook or the MacBook Pro which would highly benefit from the Apple Silicon.
It’s interesting to note that the Mac Pro is still in stock. This could signal that it won’t get updated this fall. The Mac Pro wasn’t updated since its release in 2019. As I’m looking to get one for my SDDCbox project, I’d would love to see a refreshed configuration in time for me to consider and pickup.
