Can we please get a Microcenter in every state!
... and then ideally around the world.

I was also going to approach Best Buy about them price matching Micro Center which I know they would. However, Best Buy doesn't even offer the 128GB Unified RAM model. The highest RAM model that they currently offer is the 48GB for whatever reason which I find quite odd. 🤔 - Nonetheless, still worth the potential $1,500 savings.

If I have any luck with either one of those locations, I'll be sure to post the details. And if anyone else has a process that has worked to acquire this exact model for $3,500 then please share as I checked just about every Micro Center location for this model and they're all Out of Stock and won't offer any sort of rainchecks or price honoring even if this model were to rejoin their inventory. Thanks...

There are other cases, especially in IT, where I may prefer to have more than 1TB of internal storage.

I've had a 512gb laptop for work for longer than I can remember and have never come close to maxing it out, especially these days when network or cloud storage are readily available.
I have a 1tb laptop for personal and it stores and manages 30k photos. For me, I don't have the right tool for the job anymore (when my desktop became obsolete) but I really need to offload those. The rest of my sensitive or larger files are on a NAS.

Nature of the Vulnerability
The GoFetch vulnerability is a type of cache side-channel attack that exploits the data memory-dependent prefetcher (DMP) in Apple's M-series chips. The DMP is designed to predict memory addresses that running code will likely access soon, thereby optimizing performance by preloading data into the CPU cache. However, this feature inadvertently allows attackers to extract cryptographic keys by manipulating the prefetcher to treat certain data values as memory addresses, which can then be observed through cache side channels[1][2][3].
Impact and Exploit Conditions
The vulnerability allows attackers to extract secret keys from cryptographic operations by running a malicious process on the same CPU cluster as the targeted cryptographic process. This can be done without requiring root access, as the exploit only needs the typical user privileges that most third-party applications have[1][2][3]. The vulnerability affects a wide range of cryptographic implementations, including those using OpenSSL and post-quantum cryptography protocols[1].
Mitigation and Challenges
While the vulnerability cannot be patched directly due to its hardware nature, some mitigation strategies have been proposed. These include using third-party cryptographic software with added defenses, such as cryptographic blinding, or running cryptographic operations on chip cores that do not have DMP functionality. However, these measures can significantly impact performance, particularly for earlier M-series chips like the M1 and M2[2][3][6].
Apple has not yet released an official fix, and the only complete solution would involve redesigning the chip architecture, which would apply to future chip generations rather than existing ones[6][7]. Meanwhile, users are advised to maintain strong security practices, such as using strong passwords and being cautious about installing unknown software, to mitigate the risk of local exploitation[5][7].

In addition, I ordered one from their Overland Park, KS location that will be cancelled at the end of today and should be put back in inventory tomorrow. I also ordered one from their St. Louis Park, MN location that will be cancelled at the end of tomorrow and should be put back in inventory my Monday the 9th. Good luck to anyone still hunting for one.
