Hi everyone Aaron here for Zollotech and today apple released a mac os big sur
11.2.1 to the public this is available to all mac os 11 big sur supported devices and will work on
your imac imac pro mac pro macbook macbook pro anything that's supported this will install on
as well as the mac mini now you can see this came in at 2.43 gigabytes this is on an m1 macbook pro
so let's go ahead and take a look at the build number we'll click the apple go to about this mac
and under about this mac let's close the window behind it under about this mac you can see the
version is 11.2.1 click on it you'll get the build number of 20d74 so that's how you know you've been
updated and this particular update was released to address a couple problems the first one is fairly
major this is specific to 2016 and 2017 macbook pro models so whether that be the 13-inch or the
15-inch and you have a macbook pro and it wasn't charging it should now charge properly so if the
macbook pro wasn't charging at all it should now charge or charge fully if you were having issues
with that so you'll have all of the same things and then if you have an m1 macbook of course
this isn't a new feature but you'll have battery health as well and so this update was released
mainly to fix that but there's also additional fixes in this that are very important and that
is specifically for security so if we go to the security website that shows us what has
been updated you can see three different major security updates the first one being an intel
graphics driver if you're on an intel device so maybe an older macbook pro prior to the m1s or
any of the others and you'll see it said in in the impact was an application may be able to execute
arbitrary code with kernel privileges and then they fixed it and it says an out of bound right
was addressed with improved input validation you can see this with the cve numbers the next one is
again an intel graphics driver issue and the major one that you should install this update for is
due to this one where it says impact a local attacker may be able to elevate their privileges
this issue was addressed by updating to sudo version 1.9.5 p2 sudo or super user do could
give you full access to your computer if they know the password but this was giving access
somehow without them knowing the password and so you can see it's available for these
versions and so hopefully you'll have updates for previous versions as well mojave catalina as well
and those are the major updates in this particular update so if you're wondering if you should
install it i would say absolutely just for those security issues alone those are pretty major so i
would definitely install it now finally i wanted to share the geekbench scores and some people had
been asking for that and this is my m1 macbook i ran this without screen recording that way
you would get the better scores and right after installing it you can see single core was 1733
multi-core was 7574 and so these are the current scores for this particular update
and you can see the build 11.2.1 now other than this many people have been asking me when will
we see mac os 11.3 and given that it's currently in beta i would say hopefully within a few weeks
but maybe not until march at this point also apple has been releasing ios updates and many have been
asking about those as well i would expect a small update as soon as tomorrow based on them releasing
this update today we could see ios 14.4.1 released or something along those lines so of course i'll
keep you updated and if you'd like to get the latest updates just follow along on the channel
