Hi everyone Aaron here for Zollotech and today apple released mac os big sur 11.2.2 to the
public this is available to all mac os big sur supported devices so that if you already have
big sur on your device you should see this update now now this comes out at the same time around the
world for everyone so you should see the update if you're not seeing it you can go to system
preferences then under system preferences go to software update and under software update wait
for it to check if it's not checking go ahead and click advanced and then click ok it will generally
check again it did take me a few tries for it to come up let's go ahead and close this take a look
at the build number and then talk about what's new so we'll go to the apple click on about this mac
and here you can see version 11.2.2 if we click on the version number it gives us the
build number that that's how you know you're on the latest version so you'll see it's 20d80
and this particular update does include a very important fix for a few different macs as well
as some security updates that we'll talk about in just a moment and so the first thing is let's
go ahead and close this for macbook pro 2019 or later including the intel and the m1 macbook pro
as well as the 2020 or later macbook air which means the intel macbook air and m1 macbook air
it prevents them from incurring damage when they are connected to certain third-party non-compliant
powered usbc hubs and docks so if you're using an external dock and they haven't complied to
apple standard which i have here this is their mfi program at mfi.apple.com this this ensures
that these accessories work properly with your apple device it gives all the information they
need how they can be certified and if they're not complying with these they could cause damage to
your device and apple has updated your mac to make sure that doesn't happen so maybe it looks for
voltages and then cuts the power to make sure it doesn't damage your mac so it's something that i
definitely think you should install as far as that goes especially if you have one of those macbooks
now if we go to security updates you can see that apple does not list any specifically for
today's date you can see it says this update has no published cve entries that doesn't mean that it
doesn't have any entries whatsoever so with every update they felt it was big enough to release
for that main fix but also for the security updates whether they're published or not so
i would definitely install this if you were thinking whether or not you should especially
if you have one of those macs because that will keep your mac from being damaged should you have a
third-party accessory that you bought maybe from amazon or somewhere else that doesn't turn out
to be compliant so for that reason as well as the security updates i highly recommend installing it
now as far as overall performance and everything i did run geekbench before i installed this just
to see if there was any differences so i took a screenshot here we'll go into the screenshot i
took two separate ones one was of single core and multi-core so you can see the multi-core was 7631
single core 1045. these actually are decent for an imac pro and then i also ran the opencl score
with 54153 so that's what i scored with the update before i installed this update as you can see here
it was on 11.2 prior to this now as you can see i've run the geekbench scores again just to give
us a baseline if performance would be about the same which i usually expect it to be you'll see
that this is a newer version of geekbench compared to the older one but imac pro has been around for
a few years so it shouldn't make any difference but either way you'll see mac os 11.2 on the left
11.2.2 on the right and the single core score and multi-core score is a little bit higher let's take
a look at the opencl score and that was actually a little bit lower so what this is basically showing
us is that the performance overall is very close but i wouldn't say that this is a reason
to upgrade or not upgrade you shouldn't see any performance differences but a lot of people have
asked me to do tests like this before and after updates so i just thought i'd share that with you
now as far as when we expect mac os 11.3 beta 3 well i was expecting it today to be honest
or sometime around today we could currently be on a two-week cycle or we could see it tomorrow
although friday is a very odd release day for that so we could see it sometime next
week along with ios 14.5 beta 3 tv os 14.5 beta 3 and watch os 7.4 beta 3. so if you're watching
for betas of course i'll update on those as well but those are available to developers and public
beta testers only and not the public so hopefully that helped you decide whether or not to install
this i definitely would if you're already on mac os big sur since it's got those security updates
regardless of them not telling us exactly what they are as well as the main fix for those
macbooks that's very important for those macbooks i'll link the security updates as well as the mfi
update page to let you know what their standard is in the description as well if you'd like to
get your hands on this wallpaper of course i'll link it in the description like i normally do
