hey,
@lkar , I’ve been reading a lot of your posts recently, and I think that you are confusing the way a supported Mac by apple goes through OS updates progressively and receives firmware updates vs. having [up-to-date firmware] on machines using OCLP. You are not the first person who has been confused by this.
Let‘s take two case studies.
#1
If I buy a 2012 mbp that was never updated in the last 10 years and this machine uses macOS 10.7 LION, for me to take this Mac all the way up to Catalina (which is the last Apple supported OS for this machine), I have to make pit stops at perhaps El Capitan, maybe also high sierra too, before I can ”make the jump” to the final Apple supported OS—Catalina—for this machine.
That‘s how OS updates work when dealing with a machine that is using supported OSes from Apple.
It is different with OCLP.
With OCLP, as long as the above mentioned machine has the final updates from Catalina (because that was the last macos that Apple supported for this machine), I don’t need to worry about firmware anymore. From there with this machine, I can use OCLP with Monterey or big sur or Ventura freely (as long as OCLP supports it), and I don’t need to think about firmware updates—That ended with catalina for the machine in case study #1. I also don’t need to think about “making the jump” from OCLP Big Sur to OCLP Ventura, the same way we thought about “ making the jump” from Lion to El Capitan to Catalina for Apple supported OSes.
#2
Now let’s consider a machine that Apple still supports for Big Sur but not Monterey or Ventura.
Now this machine is still getting firmware updates via big sur security updates. However, this same machine will not and cannot get firmware updates from apple via Monterey or Ventura, because it is not supported by apple for Monterey or Ventura.
so the question you ask yourself when using OCLP is “what was the last apple supported OS that my machine can run?” If it was Catalina or high sierra, as long as I ran all the Catalina or high sierra updates on my machine, my firmware is forever up to date, because apple is no longer pushing security updates for those OSes anymore.
However, if my machine is still supported by apple for big sur BUT NOT Ventura or Monterey, and I want to run Ventura on my machine via OCLP, then i need to keep a Big Sur partition on the internal ssd or have external ssd with big sur on it. Then I can boot into macOS Big Sur from time to time to get the latest big sur security updates, and hence update my firmware. So for a machine that can run Big Sur natively (apple supports it) but the user also wants to run Ventura on this machine via OCLP, this user should consider “dual booting”: One OS on your ssd is big sur and apple supported, the other OS —on a separate partition or volume on your ssd — boots Ventura or Monterey via OCLP. If you don’t have experience with dual booting or know what that means, maybe someone here can help you with how to do that.
This is a longer way of explaining exactly
