Erased Yosemite Unibeast boot stick

[jdowd7]

Accidentally formatted my Unibeast USB Boot stick from 2016- now I can’t boot into OSX. The bootable OS is Yosemite.

I redownloaded Unibeast and tried to create a new boot usb- but I don’t have the yosemite image so no luck there.

Any ideas?

Thanks for the link! I was using apple dev downloads: https://developer.apple.com/download/ and no luck.

Apologies, updated my specs in my profile- been a bit since I've been on the forum!

Yeah no luck with this either- keep getting:


"This version of OS X 10.10 cannot be installed on this computer."

"This version of OS X 10.10 cannot be installed on this computer."

Things to check:

1) No existing installation already there. Internet disconnected.

2) You have set the system date back to at least July 2017 - depending on the point-version of Yosemite you have.

3) Unlock and disable the automatic date setting in System Preferences. Sometimes the system will still update from the BIOS so you might need to change the date there too. There is a Terminal hack to prevent this happening if it is a problem.

4) If none of the above helps you will have to give us more to go on ...

Thanks for the quick replies on this.

Attempted all the above- even with the term hack in recovery mode on both an intel macbook pro and an M1 machine.

Just keeps saying: "This version of OS X 10.10 cannot be installed on this computer."

Running an 2019 i7 with Monterey 12.3.1
Also have the 2021 M1 with Monterey

Lemme know what other info would be helpful- thanks!
