Install Big Sur On Unsupported Mac

[Earleen Muffley]

Duringinstall of the currently latest version of Intel XTU (7.9.0.24) I receive a platform unsupported error, while my CPU is shown as supported on the download page.

The error: error 0x80070643 attempted to install on an unsupported platform

The utility starts, but shows the following message on the screen:

Also attached: intel SSU detailed view (SSU.txt)

This issue also came up with the previous (7.8) release. 7.7 was the last one that worked. How can I get this working?

Hi Steven,

I was, however it wasn't entirely the answer I hoped for. I do have a follow up question:

As I had uninstalled the last working version for my CPU, I am now without intel XTU... Only the most recent version is available on the download page.

Would you perhaps have a link to the 7.7 version so that I can install and use that one 'till it's time to replace my laptop? ^^

Unfortunately, we do not have the 7.7 version available anymore. You may still get it from third-party websites, but please be aware that we do not recommend downloads from an unofficial website, we only provide this information for your convenience.

I have an older PC with a CPU that's not officially supported by Windows 11 according to Microsoft's hardware requirements. Despite this, I've heard that there are ways to bypass these restrictions and install Windows 11 anyway. Can someone explain how it might be possible to install Windows 11 on an unsupported CPU? Are there specific tools or methods that need to be used to accomplish this, and what are the potential risks or limitations involved in doing so? Additionally, if successful, what should I be aware of in terms of updates and security for running Windows 11 on unsupported hardware?

Lastly, check the Windows 11 bypass option under the USB name. And start extracting and copying Windows 11 ISO to USB. At the time, the registry entry for checking Windows 11 system requirements will be ignored. So you can install Windows 11 on unsupported hardware.

@J_Sky_Eaton This issue might be related to the old update engine we changed since the 21.8 version. This means that if you have a version older than this and you want to install something much newer you should remove Studio using Add/Remove Programs and install it from scratch using the actual MSI.

I have a router / modem combo unit from my ISP (My Republic Australia) which I would like to install OpenWrt on. I don't have much networking experience and the device I would like to install to is not in the supported list. Is it possible and how would I go about installing OpenWrt?

If it isn't listed in the table of hardware, it isn't supported. Routers are embedded devices, usually with quite come quirks and peculiarities, and little standard adherence (so those exist in the first place), so each device needs its very own bespoke firmware image - there usually are no generic images.

That doesn't mean it's impossible to add support for it, but in your case (with a Broadcom platform) you have to consider that neither modem functionality, FXS/ phone features or DECT hardware are supportable at all (no drivers) and the wireless situation very likely isn't much better (unless you're very, very lucky and your device is using a brcmfmac supported wireless chipset, you may get b43 support capping out at 54 MBit/s at best - if at all). If you accept these inherent limitations (basically a wired ethernet-only device) and want to add support for your device, you'll need to familiarize yourself with the way OpenWrt works and check support additions for similar devices, so you can adapt OpenWrt to the needs of your device. Depending on your experience with linux and embedded system programming (and obviously how many hurdles the vendor has thrown into your direction), you're looking at somewhere between a long rainy weekend and multiple weeks/ months to first investigate what the OEM firmware has done, before then replicating that using OpenWrt's source infrastructure. Doing this effort usually feels more rewarding for SOCs/ devices that have better opensource support and whose hardware can be fully (or at least largely) supported.

I was planning to flash my device so I could run it in bridge mode as it currently doesn't have that capability. However from what I'm understanding even if I do flash the router it wouldn't be able to do much more than switching? As I primarily wanted to use it as a standalone modem this won't work for me.

There is no point of flashing your ISP device grenadier than it won't work as a modem, and you would need to buy another one. Moreover, ISP-provided devices are often of low specs, so you would lose the modem functionality to get a low specs router that will not give you a good OpenWrt experience.

If your device doesn't support bridge mode then you either keep it as it's and connect your new OpenWrt to it (that will probably involve double NATing), or find a modem-router that supports bridge mode and works with your ISP. Thise should be available as second hand (or new) for cheap as ISP provide them and then people end up having extra modem when they change ISP.

Adding new device support This article assumes your device is based on a platform already supported by OpenWrt. If you need to add a new platform, see ->add.new.platform If you already solved the puzzle and are looking for device support...

Adding a new device A good all-round advice would be to start by looking at recent commits about adding a new device, to see what files where changed and how. Many files try to be as self-explanatory as possible, most of the times just opening them...

Past releases may have different support schedules (for example, normal releases (before 13.04) used to be supported for 18 months, while LTS releases (before 12.04) used to be supported for 3 years on the desktop and 5 years on the server).

EOL: Once the support period for a particular release is over; they are called End Of Life (EOL) and all the updates and package repositories for that Release are transferred to a different server which results in 404 errors while running sudo apt-get update. You can confirm if your release has become EOL by going to this page. If your Ubuntu release is mentioned under "End Of Life (EOL)" Table, then the release is no longer supported and you should try to upgrade to a newer supported release. However, if you wish to continue using this unsupported release, you would have to make necessary modifications in /etc/apt/sources.list to point to the old-releases server of Ubuntu.

There you go. No 404 Errors this time. You can now install all the available packages for your Ubuntu Release. You can also run sudo apt-get dist-upgrade to install any Security/Bug-fix updates which have not yet been installed but you won't get any further Security/Bug-fix updates from Ubuntu.

I tested this method from a live session of Ubuntu 9.04 (Jaunty Jackalope) and as you can see from these pictures it worked. If you are on an installed session of Ubuntu, you will be asked sometimes for root or admin password. Just insert your personal user password when you are asked.

I got here since I could not upgrade a system from 15.10 (EOL) to 16.04. But none of the answers worked for me, even after doing everything that was suggested here I kept getting from sudo do-release-upgrade the annoying response:

And I had no success in running update-manager; it kept throwing exceptions which I could not resolve. I suspect something is corrupted in my 15.10 installation, but the bottom line is that the built-in upgrades just fail.

Now open the system's Software Sources dialog, and manually select old-releases.ubuntu.com as though it were your regional mirror. You should find it listed under the fake location you chose in the previous step.

Here you can try a release upgrade if your current release is not too old (sudo do-release-upgrade). If it fails, you may find some clues in /var/log/dist-upgrade/main.log which could help to find a fix.

There is an edge case - apt-get claims 16.04 LTS does not exist - where the old package (Vivid, in my case) was not in on the "old-releases" server. But apt-get could only find kernel and Google updates.

Carefully go through all the sources and discover one of them was old and wrong and had failed to be properly updated (or something). Or, as I did, search replace from old-releases.ubuntu.com to gb.archive.ubuntu.com. It then upgraded, without a problem, to the next release while I caught up on some reading.

The takeaway here is that while the majority of answers here may apply in some cases it would pay to be sure that your /etc/apt/sources.list is correct before you nuke it for the "old-releases" archive.

You can figure out which of the archive or your mirror has the version you need by simply pointing a browser tab at the archive and question and looking for your version name in the folder list. Whichever one has your version, is the source you need to use.

If you have EOL release and if you do not afraid of reinstalling your system from scratch or just without formatting this older system, than you could try it. It tried only of curiocity and for testing purposes. Not real hardware, but VM have been used for this. DO NOT USE IT ON PROD. But strangely if you have EOL on prod.

Reason:

If you have a "bare" system, then the "upgrade" options will work perfectly.

But most often you have added many optional changes and tweaks; these are prone to get in the way of the upgrade (software, scripting) - i.e. create problems for a smooth transition.
