Yosemite Public Beta Bootable USB installers

I'm trying this right now - why is there a long wait? Does the OS have to compile it or something :S

It just takes a long time to copy the GB's to a flash drive. If you have a USB 3 drive, it'll probably go much quicker.

Ahhh. So the terminal command does all of this automatically?

Yep it sure does.

Since I couldn't find my USB flash drive, I put the bootable USB installer on a SanDisk 16GB SD card that was inserted into a Transcend USB 3.0 card reader. It installed and will boot from the SD card but performance is very slow.

Rebooted back to Mavericks and removed the card from the reader and inserted into the SD card slot on the MacBook Air. And it will boot from that as well. Performance still slow.

My guess is I will need to partition the main drive on the Air and clone the install to the partition and run from there. Otherwise it won't be enjoyable. One side effect of running from an alternate location is that any licensed software wants to have license entered as it does not recognize the machine.

I've tried it twice and it didn't work...

I added a password to my account and now it works! Just a heads up incase anyone has similar problems.

I was able to successfully create the bootable USB, but can anyone help me with installing it in VMware Fusion 6.0.4?

I'm running Mavericks 10.9.4 but want to run this Yosemite beta in Fusion. Any help would be appreciated.

I tried the method described in the VMware blog post below, but it doesn't seem to work bc it gives me "Operating System Not Found" error.

Thanks in advance!

Not mavericks

Would this allow one to install to an external USB even if the primary system is NOT mavericks? I'd like to run this, but the system I have on me is ML?

I have the better installer from the app store though.

TIA

My install is slow using an SD card so I have partitioned an external USB 3.0 drive that should be much faster.

Would I be better off installing the OS to the partition, or using CCC to clone the SD card to the partition?

Installation stuck in "About a second remaining"

Hey guys,

I did your command to put yosemite beta into a usb with 8gb.

The thing is that my installer is in the message "About a second remaining" like a 30 minutes or more.

I checked the log and it's says: " Verifying InstallMacOSX.pkg/InstallESD.dmg".

Someone knows what should i do ?

btw, i did a full format of my HD

Update: After 1 hour, he finally restarted.

 

[S.B.G]

That "About a second" thing remaining happened to me too. I just let it sit a while, not quite an hour though, and it completed.

Am I right in assuming that if I want to install this one a bootable USB drive, that USB 2.0 is going to be way too slow and would need a USB 3.0 Drive?

No, not really. I used a USB 2 flash drive (in a USB 3 port) and it took maybe 20 minutes to copy the files over. But if you have a USB 3 flash drive and a USB 3 port, it'll go way faster.

I think Koodauw probably meant he wants to install the whole system onto the usb. That's a completely different thing, and then a fast usb 3 would be better.

This thread is really only for making a bootable usb installer, not to run the whole system on a usb. For usb installers, a usb 2 is fine.

To run the system I think a partition on your main drive would be better than running it on a usb stick.

Ahh yes, I think you're right and I misunderstood what he wrote. In that case, yeah, a USB 2 drive would be too slow for most people to want to run it from.

Just did this

I just did this with a USB 3.0 drive I had. 40mb write, about 90mb read.

I downloaded the OS X 10.10 installer to my local machine (which is still running ML mind you) and ran the local installer, pointed to the USB drive, let it reboot and install.

Worked like a charm. I wish the USB 3.0 was one of the faster 200MB versions, but it seems to work fine as is, and keeps everything very discreet.

took about 20 minutes all in.

Thanks everyone. I do want it to boot from the USB drive. I tried it with a USB 2.0 drive last night and it took hours and often froze. Never got it to boot. I'll look at USB 3.0 drive today. I saw Best buy had them on sale.

Hangs on Boot Screen

It should. That's what I did. I used a USB drive to put the installer on, then installed it on an external USB 3 SSD and it's working just fine.

. I'm using a 32gb 2.0 thumb drive, with a 6gb partition (for Yosemite Install Bootable) and 26gb partition to install it on. First of all the install took FOREVER. Then when finally done it restarts gets half way through boot screen and hangs.. I have restarted it a couple of times, and I have rebooted back to option screen and selected the "Yosemite Install" as I read in another forum, NO DICE so far!! Any thought or ideas?

Are you using the same thumb drive for the OS and the installer all on one?

Using a USB 2 drive, regardless, will be painfully slow, and may be the root cause of it locking up. If you can find a USB 3 drive or SSD to use as the boot device, that will make a dramatic improvement - providing your machine has USB 3 ports.

Here is how to make a bootable usb of the yosemite public beta 1 installer. It is much easier than for yosemite DP1 and similar to how you do it for mavericks (but obviously the installer name has changed).

Format an 8 GB USB drive which should be called Untitled and formatted as Mac OS Extended (Journaled). The installer should be called Install OS X Yosemite Beta.app and should be in your Applications folder.

Run this in terminal and wait about 20 minutes:

sudo /Applications/Install\ OS\ X\ Yosemite\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite\ Beta.app --nointeraction

You can boot up from it by selecting it from the startup manager you get when starting your computer and holding down the option key.

Thanks! Your a lifesaver.

 

[TyWahn]

Does the installer have to have the .app extension even tho it already does it's just hidden?

 

[tywebb13]

Yeah. The app extension is hidden. It will appear in your Applications folder as Install OS X Yosemite Beta after it has downloaded.

 

[TyWahn]

Right but do I need to ADD it even tho it's hidden. Sorry if i wasn't clear.

 

[tywebb13]

No. Don't add anything to the name. It's already there, just hidden.

 

[TyWahn]

Thank you, Ty for your fast responses. Very appreciated.
