Hi there,

is there a (e. g. SHA256) checksum available for the image?

Feels always better to konw for sure that you've downloaded the "real thing".

Thanx a lot!!!

guru mediation on virtualbox and vmware unlocker only has 10.6 server

If you're having slow download times, download the torrent file instead, i'm getting 1.6 MB/s with it (your download speed might vary by where you are in the world and the time of day) otherwise, this is a great ISO!

This .iso worked - my 9,1 is now up and running. Thankyou iApple. It’s a long post - but is a result of days of research and trial and error - wasted three days on a .dmg that sucked all my bandwidth and did…..nothing.

I’ve made the steps as detailed as possible.

For the purposes of this, if you see disk5 - then you will insert your own disk number based on your configuration.

1. Download the ISO image (takes a long time, once finished I also did another copy in the downloads folder just in case)
2. USB stick minimum 8GB into USB port
3. Finder -> Applications -> Utilities -> Disk Utility 
My USB name is 8.05GB Vendor Co 
Underneath is ‘No Name’ 

Important step - initialising to GUID Partition 
Click on 8.05GB Vendor Co (or whatever name yours is) 
 Select Erase
 Name (your choice) 
 GUID Partition, MAC Extended (Journaled)

4. finder -> Applications -> Utilities -> Terminal
these commands are in Terminal (the $ is the cursor which is the default in Terminal)

$ diskutil list
(lists drives - the USB of 8.05GB is /dev/disk5 with sub partitions of disk5s1 etc

$ umount /dev/dev5
(this completely unmounts the disk - takes a minute or so you'll get a message saying all partitions unmounted - DO NOT eject in Finder)

$ cd ~/downloads
(this changes your directory to the downloads directory where you have your .ISO file)
File name is Snow Leopard Install.ISO

Read the notes below the sudo command below - important

$ sudo dd if=/"Snow Leopard Install.iso" of=/dev/rdisk5 bs=1m

the 'r' in front of your disk name (mine is disk5) will speed up the transfer process,
 as will putting the block size as 1m at the end -
it took 895 seconds to transfer 77 GB using this method!

To see the progress you can to see how much has been transferred.

If you want to see if the process is still working use to see the processes running - use Profile at the top to change how Terminal looks - info to see running processes down the bottom right (this process will be seen as -sudo at the very bottom)
Now you have transferred the image we eject the disk

$ diskutil eject /dev/disk5

$ exit (shut down terminal by ‘x’ if you wish)

Big question is - is the USB bootable - all I did was remove it and then plug it back in - the contents auto appears on the iMac with the install DVD app - that’s how you know it’s bootable!

On the Mac 9,1 - USB into drive, power up machine whilst holding down the Option key - here is where you should now see either the Macintosh HD OR if the above worked - the MAC Install DVD - which is what the iMac now calls it - select this and follow the prompts to install 10.6

The USB contents displays once done so did the ‘optional installs’. 

Then apple logo, software update, it checked and said downloads available and downloaded 4 items. The 9,1 is now 10.6.8 and ready for El Capitan. Did a net search, found links on the https://support.apple.com/en-au/HT211683 site showing both hardware and software upgrades. Did the El Capitan as this upgrades from Snow Leopard (skipping Yosemite). Another site - here - checks your serial number https://everymac.com/ultimate-mac-lookup/

If you want your serial number, go to the About this Mac page on the 9,1 then ‘more info’ then the serial number is the second entry from the bottom on the hardware list.

Still question JB Hi Fi selling us the 9,1 with Leopard OSX in June 2009 (Snow Leopard released June 2009). Sadly no notifications from any source that you then had to purchase the Snow Leopard upgrade. The fact it stopped browsing websites was the trigger. Just a few tweaks to ensure it doesn’t keep doing it. This is a great YouTube vid if you do https://www.youtube.com/watch?v=fzZ7LHznWV4 - in my case - the ipv6 setting did the trick!

Thankyou to iApple for uploading this. Thankyou for helping me resurrect the old iMac. Was searching for ways to destroy the hard drive - instead - found ways to give it a new lease in life!
