Can't install MacOs Tahoe on Mac Studio M3 Ultra

I just tested it by downloading the tahoe beta9 installer (~16.84G) and installing it on a 15.7 system, and the result was the same as if I had installed the official version directly, and after a few minutes of waiting, the beta9 installation failed and it returned to 15.7

Just for context, I need Tahoe to test specific software as part of my beta testing process. I’m well aware of the pros and cons of new updates, but testing in Tahoe is essential for me. I was hoping a proper update would be available by now, or at least a workaround.

Well, I know I reported every error to Apple as well as during live chat with them. Kind of a presumptuous take IMO and a bit of an overreaction to the post. People are entitled to feel this way since we are, in fact, talking about a specific. computer that starts at $4K.

It is ok to feel frustrated, but so many people are only discussing issues like this on the forum without actually alerting Apple to the problem through the proper channels which ends up with users frustrated and Apple unaware of a problem or the extent of a problem. Online posts are not sufficient for Apple to troubleshoot a problem since those posts rarely contain any or enough significant details. If people want Apple to fix something, then they need to report the issue directly to Apple.....the Apple forums are not the proper method for reporting issues to Apple. Unfortunately many people do not realize this.....hence my post.

And good for you for contacting Apple about the issue. I don't think enough people do that.

In the last two weeks of had 15.6/15.7 freeze after login twice to the point that my user cannot login and the only way to recover is through a fresh install.

Normally I would not update this early but it’s that or this machine is getting thrown out the window. I was very happy to be able to do a DFU update as the next step would have been sending the machine back to Apple if I experienced the login issue again.

I have given Apple every detail possible on this along with how I resolved it.

I also did call Apple and ask for a solution...Their reply: – keep trying...eventually it will be resolved. This is unacceptable for a US$ 10 thousand dollar machine . This is the beginning of the end for Apple. They are lagging behind in AI field (also they announced improvements for AirPods 2 Pro and newer (firmware 8A253, model A3048) and live translation is a flop. It simply does not work. It remembers me Apple Maps flop decade ago.

I would highly recommend resolving the issues while running Sequoia because Tahoe will just introduce even more possible issues with your third party software.

Please start a new thread for assistance for your Sequoia issues. Include an EtreCheck report in your post to help the forum contributors analyze your system.

Thanks HWTech but I have already tried that and that resulted in a system that didn't start.

Without an option to reinstall I ran DFU restore once more. This time I noticed that migration stops after transferring 1 400 000 files out of 1 750 000 files. And then I am back to a basic Apple Tahoe system without any of my files. I give up and will visit an Apple Store and hope they can help.

Try a different backup and compare your results....(?)

More than one device, more than one backup methodology. 

Yes, I have tries that several times. It looks like it is working but stops before all files are transferred and I end up with a basic system without any of my files! I have no idea why migration doesn't work for me. Will go to an Apple Store tomorrow and hope they can help.

Migration may work for you as it has worked for others.

Going back to Sequoia sounds like a great idea. I asked Apple support about that but they did not recommend it and didn't want to help. They said downgrading is against their policy. But since my Mac isn't usable I might as well downgrade. I think I'll postpone my visit to the Apple Store and try some more…

Thanks! Will keep you posted!

If want to use Time Machine or Migration Assistant for DFU recovery, you must remember to delete Orbstack from the system before backup, because Orbstack will generate a sparse file of 8Tb, and it is this sparse file that will make the backup process stuck!

The same thing happened to me the first day. I was told by several Apple agents that there was no known issue. I was guided through doing a safe install, which failed. I was guided through creating a new administrative account, and installing that way, which also failed. Is there any estimated time for when this issue will be solved?

Well, I escalated my situation, and the advice from a higher level Apple agent is to wait until the engineers solve the problem. He said that working on it very hard. We did discuss the possibility of having one Apple Computer somewhat force my M3 ultra to accept OS 26, Tahoe.

Apple would certainly benefit from reading these forums, rather than providing them just for users' opinions which don't lead to anything more often than not.
