Researchers have found an un-patchable vulnerability in the latest Apple Silicon M-series chips, including M1, M2, and M3. M-series chips are used in the latest Mac and MacBook devices.
‘GoFetch’ Vulnerability
Researchers are calling it ‘GoFetch‘, as it allows hackers to gain backdoor access to secret encryption keys on Macs and MacBooks.
The vulnerability lies with the components called ‘prefetchers’. The main job of Prefetchers is to retrieve data before it is requested, which results in increasing processing speed.
But, these prefetchers also create a door for malicious attacks. The researchers have called this vulnerability ‘GoFetch’. Researchers have described it as a microarchitectural side-channel attack used in extracting secret keys from the cryptographic implementations via memory-dependent prefetchers (DMPs).
The researchers informed Apple on December 5, 2023, but Apple didn’t give enough attention. After no positive replies from Apple, the researchers have made this information public.
Side-Channel Attack
A side-channel attack is a cyber attack that utilizes extra information that is left vulnerable due to the design of an algorithm or computer protocol. In this scenario, the DMPs that are installed in Apple Silicon chips can give access to sensitive information to hackers.
Solution?
This vulnerability cannot be patched with software because the real issue is with the microarchitectural design of these chips. Any changes to the design will degrade the performance of these chips.
If Apple tries to fix it in the M4 chipset, it will surely see poor performance, meaning, an M4 chip will run like an M2 chip with a fix.
If you’re in the market for a sleek and lightweight laptop, chances are you’ve considered the Apple MacBook Air.
But with the recent release of the M2 and M3 versions, you might be wondering which one is the better choice for you. Fear not, dear reader! In this article, we’ll break down the key differences between the two models and help you make an informed decision.

Winner: M3 wins again, thanks to its ProMotion technology for a better visual experience.
Battery Life
M2:
The M2 offers impressive battery life, lasting up to 15 hours on a single charge.
Whether you’re attending classes or binge-watching your favorite shows, the M2 won’t let you down.
M3:
The M3 pushes the boundaries further, providing up to 18 hours of battery life.
It’s like having a portable power station in your backpack.
Winner: M3 takes the crown with its extended battery life.
Price and Value
M2:
The M2 is the budget-friendly option, starting at $999.
For students and casual users, it’s a fantastic value for money.
M3:
The M3 commands a slightly higher price, beginning at $1,199.
If you’re a professional who demands top-notch performance, the extra investment is worth it.
Winner: M2 wins in the affordability department.
Verdict
In the battle of Apple MacBook Air M2 vs. M3, there’s no clear winner—it all depends on your needs. If you prioritize affordability and everyday tasks, go for the M2. But if you’re a power user who craves performance and doesn’t mind spending a little extra, the M3 is the way to go. Whichever you choose, you’ll be getting a beautifully crafted laptop that seamlessly integrates into the Apple ecosystem.
