Hi John, I've put your post back 'onlist' as your reply was to me 'offlist'. What to suggest you do now that you have erased the iMac... So this is not the iMac you mentioned in your first post to the list "27"iMac/2012/10.9.2/3.2GHz/8GB RAM"
If the iMac is an Early 2011 Mac or earlier that originally came with 10.4,10.5 or 10.6, or upgraded to 10.6 via the 10.6.3 Retail disk. This will NOT work if the iMac is a 2012 that came with a newer operating system 10.7/10.8 or 10.9 I will also send you "Offlist" the instructions below including an image file (as WAMUG does not allow attachments) showing you the entire internal boot drive mentioned below. But please post back to the list with your results. Write down the User Name and password etc you used to setup this iMac. Erasing the boot drive: With all other drives disconnected your ready to erase 10.7/10.8 completely off your boot drive, and you do need to erase the ENTIRE drive. 1. Hold c (or option key) boot off the 10.6 installer disk and under the Utilities menu is Disk Utility. 2. Select the entire internal boot drive on the far left, it will have the drive makers name and size. Note: Do not select the indented names, those are just partitions on the drive, you need to erase the entire drive to catch hidden 10.7/10.8/10.9 partitions and rebuild the partition map back to 10.6 version. 3. Click Erase > Security option > Zero All Data (will map off any failing sectors) go watch a movie, it takes a bit and improves your hard drives reliability and read speeds. (SSD no need zero, just erase). 4. Check under Partition: Options that you have a GUID and Format: OS X Extended Journaled, if not change it to those and apply. 5. Quit Disk Utility. You will be back into the 10.6 installer. You have erased the internal drive via the 10.6 disk and need to install fresh. Quit Disk Utility and install 10.6. from the installer disk. 6. Reboot, setup and use the same user name as on the 10.7/10.8/10.9 boot drive. You wrote that down I hope, right? 7. Use Software Update to get up to 10.6.8 fully. Better still Go here and download the Combo Update: Snow Leopard 10.6.8: <http://support.apple.com/kb/DL1399> 8. Repair Permissions This is very important to do or you'll have problems later. Install all programs from fresh sources and compatible with 10.6.8 Cheers, Ronni On 28 Jul 2014, at 4:18 pm, Jon Davison <jondcamera...@me.com> wrote: > Sorry for the confusion Ronnie.
