hi everyone Aaron here for ZolloTech and Apple surprisingly released iOS 12.4.2
this is available for iPhone 5s, 6, or 6 plus and supporting
iPads as well I'll list them over here but this particular update is more of a
security update and maybe a small performance fix so let's go ahead and
take a look at it now depending on which version you're actually updating from
the size of the update can vary greatly you'll see on the iPhone 6 that I have
here it's 2.3 6 gigabytes so it can vary greatly depending on which version
you're updating from on the iPad air first generation that I have here you'll
see it's three hundred and 1.6 megabytes and this update says it includes
improvements provides important security updates and is recommended for all users
now before we talk about what's actually new in it let's take a look at the build
number you'll see the build number is 16 g11 4 and the interesting thing about
this particular build is there is no IPSW or update file for devices that
support iOS 13 so if you have an iPhone 7 8 10 any of those you cannot get
twelve point four point two it's just not available so what they've done is
gone back and patched a security vulnerability that's in the 5s the 6 the
6 plus supported iPads but also they've pushed the same security update to Mac
OS and watch OS so watch OS gets updated to five point three point two if you
have an older watch on Apple watch series 1 and Apple watch series 2 until
they get watch OS 6 which comes a little bit later for some reason and then also
Mac OS 10 point 14 was released to include the same security update so I
don't think this is specific to jailbreakers and so what it says is a
remote attacker may be able to cause unexpected application termination or
arbitrary code execution and so that hopefully fixes whatever that
vulnerability was found in where people can remotely access your device and run
code and maybe take control of it now that may or may not refer to a jailbreak
but I don't think it's specific to that just because of those Mac OS and watch
OS updates now as far as performance and changes like that I really would not
expect much of a change in fact I don't think
you're going to see very much and also if you're part of that jailbreak
community I wouldn't update anyway in fact my iPhone 6 is actually on iOS 10
so you'll see it looks very different I like to keep older devices on the older
updates but I have tried this on the iPad air which this is running that
version and it seems to work fine it does feel a little bit faster not very
much but a little bit now other than the security update that I've already
mentioned there isn't any physical changes that I could find I could find
no one talking about anything they've found and you'll see it does seem to
actually work a little bit better than it did before the Settings menu does
have a little bit of stutter from time to time but it's much more usable than
it was prior to this update so they may have tweaked something in the background
if I go into Safari for example you'll see there it's a little bit jittery here
but much better than it was before with the iPad air so whatever it is I would
say it's a little bit of a performance boost but I wouldn't say it's a
phenomenal update and to expect a bunch of changes this is more of a security
patch and that's it that's it for iOS 12 point four point two and I'm glad to see
apples actually continuing to update security and maybe fix some bugs that
are in the background although they're not really talking about that but that's
really it let me know your thoughts about it in the comments below if you'd
