The software on many 2018-2021 GM models equipped with an Infotainment 3.Double click to open it, then launch the Terminal application. After that, press the Enter key again and the trash files will be deleted from your Mac.About time for another blogpost I reckon! And well aware of that fact that I may be opening Pandora’s box here, not to mention a can of worms, let’s have a look at what our options are in view of keeping our Macs up to date.The GM twins, Sierra along with Silverado can jointly enter in the new section. When you enter the password, you won't see any change in the Terminal screen. Then press the Enter key and provide the admin password. Select all the files that you want to delete and drag them to the terminal window. Step 2: This will open the Trash folder.
Enter In Terminal For Software Update Strategies AsBut if it turns up a Could not load Software Update Preference Pane error, then you need to find another way to install those critical. Just click Apple menu > About This Mac > Software Update. If your macOS has pending updates to be installed, the easiest way to install them is via the Software Update window. The only intent is to help fellow Mac Admins to understand the current challenges.You can use an external drive or secondary volume as a startup disk from which to install the Mac operating system.These advanced steps are primarily forSolution 1. No judgements calls are made in this post. When prompted, enter the admin password to complete the change.Disclaimer: My intent with this blogpost is to discuss the available options for macOS Big Sur update strategies as things are at the moment in view of some changes native to Big Sur and Apple Silicon Macs.Use the ‘Files and Processes’ payload in a Jamf Pro policy Use the ‘Software Update’ payload in a Jamf Pro policy Deploy a configuration profile to enforce automatic updates Do nothing and educate your end users to keep their devices updated, maybe remind them from time to time with a notification via a Jamf Pro smartgroup and policy. If you are not able to remember the username or password, or if your computer.Let’s first start with listing what is available as tools and functionality to achieve our goal:This however, brings up the discussion on passing admin (or any for that matter) credentials in clear text in a command or script. I’ll leave this path at providing you the link where this approach is explained in detail: Note: One thing I do want to highlight is the fact that for Apple Silicon devices, this will only work if you provide a username and password of a SecureToken-enabled admin account in the command. For instance by caching the installer and provide a one click button in Self Service to speed things up. Unless you are only having tech wizards as end users, who can manage an erase/install/re-enroll on their own, but even then, you may want to keep things easy. Unfortunately, like I mentioned above, things got a bit complicated, and with some unexpected behaviour and bugs, I mean features, we are actually a bit limited in view of what actually works.That said I’d like to start with the following Jamf tech write up on the topic: I’m sure my colleague-tech writers are gonna forgive me for using the below flowchart, so let’s have a closer look at it:I did not include the ‘erase’ scenario in my list here above, but yeah, if your goal is to wipe and re-install macOS, using the –eraseinstall flag on the startosinstall binary would be my preferred way of doing things. Use any other 3rd party tool and or script, like nudge (see below)As you can see, quite some options, but are they all even efficient? Well, in a perfect world we would be able to pick a flavour which suites our deployment strategy, and go for it. This was fixed in Jamf Pro 10.23, but Apple Silicon / M1 Macs made this issue resurface. Why? Well, first of all, because they are available and are not limiting us to use the pure built in functionality of Jamf Pro, but also because what happened over the recent macOS and Jamf Pro versions.In view of keeping this post within acceptable length, I’m not going to elaborate each issue or roadblock we saw, but instead summarise it as follows.First of all, starting with Macs equipped with a T2 chip, we saw that using a Jamf Pro policy with that ‘Software Update’ payload resulted in failing updates if the update required a shutdown instead of a reboot. The command you'd use if you want to go that route would be like: echo 'mYsup3rS3cur3P4sSw0rdW1ch1w1LLn3v3RpUt1N4Scr1Pt' | '/Applications/Install macOS Big Sur.app/Contents/Resources/startosinstall' -eraseinstall -agreetolicense -forcequitapps -newvolumename 'Macintosh HD' -user adminuser -stdinpassMoving to the left side of the chart, where we retain computer data, ignoring using recovery mode, we have:Those are basically the main 3 options we can use, but as you saw at the beginning of this post, I added a few more. ![]() What does that really do?This together with educating and reminding end users (with Jamf Pro Policies, additional Notifications, etc…) could be a strategy if you don’t require much enforcing of updates at a specific time.But if you do need to really force updates without user interaction or passing of credentials in scripts and you do have Apple Silicon / M1 Macs in the mix… there is, as things are at this moment, only one option left: MDM / Remote Commands !The reason why, is because Apple Silicon Macs can now use the ‘Bootstrap Token’ ( if escrowed into MDM), to install updates triggered by MDM commands without user interaction. “Enforce” automatic updates via a Configuration Profile…. Do nothing and educate your end users to keep their devices update, maybe remind them from time to time with a notification via a Jamf Pro smartgroup and policy.The first option is self-explanatory I guess, so let’s quickly have a look at option 2. In macOS Big Sur pre macOS 11.2, there was an issue with the AvailableOSUpdatescommand. Even if I’m presenting MDM / Remote commands to tackle both Intel as Apple Silicon Mac updates, we are not quite there yet, because ( as things are at the moment of writing this), there are still a few roadblocks / issues.First of all we have macOS Big Sur before 11.2. The exception is however that if the ‘Bootstrap token’ is escrowed into the MDM server, MDM commands to update M1 Macs do not require this user interaction!And this is the only way, at the moment of writing this blogpost, to automate MacOS Big Sur updates on M1 Macs without passing or prompting user credentials.NO! Wait! I did mention that writing this blog post was like opening a Pandora’s box style can of worms right? Yes, indeed. Easiest nes emulator for macAvailableOSUpdates – Instruct the Mac to report the available updates back to the MDM server ScheduleOSUpdateScan – Instruct the Mac to scan for available updates. When you instruct a Mac to check for updates via MDM there are actually multiple MDM commands involved. “Download and Install Updates” command would send the Default action, which would download and trigger the installation of an update.This all worked well before macOS Big Sur. “Download Only” command would send the NotifyOnly action, which would download the update and notify a user of the update’s availability. This depending the option selected on the initial MDM action: I cant sync gmail to outlook for macWhenever this command is issued to macOS Big Sur pre-11.2, it would actually result in a situation where the available update disappears from System Preferences and the install via MDM fails.
