        There’s another Intel chip flaw:

        https://appleinsider.com/articles/20/03/06/new-intel-chip-flaw-threatens-encryption-but-macs-are-safe

        However, most modern Macs with a T1 or T2 chip are safe from the threat. Even older Macs without T1 or T2 chips would be difficult to implement the attack.

        Yet another reason though while Apple is likely wishing to pivot away from third-party chips to designing its own CPUs in a Mac.

        Nathan: This paragraph in the article you have pasted the link to worries me a little:

        Of course, older Macs without a T-series chipor the present iMac lineup minus the iMac Pro —may be vulnerable to the exploit, which could affect FileVault encryption.” (Emphasis mine.)

        This seems to be saying that old Macs and also iPhones, iWatches (?), etc. except the iMac Pro (a from regular to top-of-the-line desktop computer that all it has in common with the other “i” is the ‘i’) are at risk of having the contents of their HD or SSD, or whatever those “i” things have for mass storage devices) taken over by evil hands with all manner of bad things ensuing.

        And those “old Macs” how old are they? I have a mid-2015 laptop MacBook Pro, and I am not sure whether it is above or below the line separating old Macs from the rest.

        Edited after looking around and finding out: No, I am out of luck. The T1 chip was included in the Mac hardware starting in 2016 and the T2 in 2018:

        This would only affect Macs. iPhones, Apple Watches, iPads, Apple TVs, etc., all use Apple’s own CPU’s. This is an Intel-only vulnerability.

        This could affect Macs without a T1 and T2 chip, but even then, it would be difficult to implement it.
