These updates make changes to the core operating system, including first-party apps like Safari and Mail, and they may include firmware updates for hardware and peripherals. These patches are referred to simply as updates and recorded in the version number, with 13.3 being the third major update to macOS 13. In between major updates, supplemental patches are deployed to fix bugs, patch security holes, and sometimes add new features and support for new products. How to Install macOS UpdatesĪpple releases a new major version of macOS each year, usually around October. You can automate much of this process so that your Mac updates everything automatically without bothering you, too. Apple and app developers patch security holes when they're found-and they add helpful new features to macOS and your applications, too.īeyond the usual security patches and app updates, Apple offers shiny new versions of macOS to Mac users every year-for free. Do not change this entry.Keeping your Mac up-to-date may seem like a chore, but it's an essential part of protecting yourself online. # localhost is used to configure the loopback interface If you totally mess up your hosts file, here’s what the default hosts file should look like: # I didn’t even have to restart for it to start working, but you may want to just to be sure. Mac OS will ask if you want to replace the hosts file – simply select yes. The hosts file itself is not editable where it is, but you can drag out a copy, edit that, save it, then drag that file into the directory. You will need to use Go To to get there, as the /private directory is hidden, or you will need to enable the viewing of hidden files (Command + shift + period). You can find your hosts file under /private/etc/hosts. Since this is an OS file, it affects every user on the system. Simply commenting out this line (or deleting it) freed up the whole process, and everything went smoothly. At some point, one of the OS X installations had placed in the hosts file a line for gs., and that was gumming up the works. Back in 2010 we didn’t have T2 security chips. Remember how I said I had upgraded from a 2010 Mac to this one? Well, the migration was the problem. This is exactly how I found the MacRumors post that had my solution. One of the key errors I found in the installer log was “The signed AP ticket could not be found”, and I need to state that error here, because if you’re Googling for “ The signed AP ticket could not be found”, you’ll find this post that may help you. The senior advisor and I took a break to try to let a different installer method run for Big Sur 11.6, but it didn’t work. Sure enough, failure after failure, with a tech and then a senior advisor on the line, no one knew what to do here. When the Mac OS Big Sur 11.6 update rolled out I was wary of trying it, knowing I’d probably be packing up my machine and taking it down to Apple again. They assured me it was not likely to happen again but sure enough… it did. They tried it multiple times as well, and ended up completely flashing the drive and using a configuration tool, which then, and only then, did the update take. The only way I got from 11.1 to 11.3 was taking it down to Apple. I tried everything to clear this error: restarting, shutting down, a file system check (both through single user boot and Disk Utility), a fresh and new admin user account, resetting the PRAM, resetting the SMC, safe mode/safe boot, recovery mode, internet recovery mode, using terminal to run softwareupdate, connecting via ethernet, using someone else’s wifi, downloading the package in multiple ways… None of it worked. It would download the whole thing without an issue, and then when it went into preparing the installation, it would hang, then error out with “Download failed… check your internet connection”. The issue was, no matter what I did, I could not get the update to go through. It came pre-loaded with Big Sur 11.1, and barely a month later, an update came out for Big Sur 11.3. The Problem: Can’t update Mac OS Big Surīack in April, I upgraded from a 2010 iMac to a refurbished 2019 Mac Mini. If you just need the solution and don’t want to hear how or why, you can skip to the solution here. I want to post about this particular issue that may have you tearing out your hair, as I was tearing out mine working on it. I don’t post a lot about computer issues and their solutions (after all, this is not a tech blog), but when I do, it’s because the solution is not readily available on a quick search.
