Just an off-topic and probably hardware Mac question…
My admittedly old (2006) 24" iMac is starting to show ‘ghosts in the machine’…or ghosts in the display, particularly. It’s like colour noise, but in lines or blocks. Sometimes resizing the working window makes it go away, but then it will return. This morning half the icons in the dock were broken like this, but when mouse-overed came into focus.
Any thoughts on whether this is hard drive, the display or video memory problem? (TechTool says video memory is ok, as is main memory)
Thx

Well I took the plunge…and have a ‘new’ Mac (secondhand, of course!)
It’s a 24" iMac running Yosemite at the moment, with a 1TB hard drive.
Now I selected a model that would still be capable of running Snow Leopard - as this is vital due to software use and need for Rosetta.
I’ve partitioned the disk on the new iMac and want to ‘clone’ my current hard drive to it. Connected up the Macs with an ethernet cable, they can see each other. Opened Carbon Copy Cloner on the old Mac and tried to select a target - my new ‘snowleopard’ partition shows, but has a small red ‘no entry’ symbol and I’m told that I don’t have permissions to access that folder.
Anyone know how I can make it permissioned so I can use it as the target destination for CCC?
I’m trying achieve a second bootable system on the new iMac, so Yosemite is in one partition and Snowleopard in the other - hopefully selectable at startup.
Any advice welcome, thanks

Try connecting the two machines with a FireWire cable. The one that you want to install on – start it up with the Command + T keys held down to initiate Target Disk Mode. That turns the Mac into a very expensive external drive. Now start the other Mac normally, and the first Mac’s hard drive will mount to the desktop as a disk. You can now clone away, without regard for permissions. Bonus – it’s much faster than Ethernet.

Thanks Walter, nice idea. I had thought of that, but unfortunately the Firewire cable I have is the old style connector, whereas the new Mac has the new style (Firewire 800…?) so my cable won’t work (i.e. it fits the old Mac but not the new one!)
In the meantime I have made a ‘bootable’ clone of my hard drive onto an USB external drive. I’ve hitched that up to the new mac and booted from the external drive ok, so the boot copy works.
So now…how to get the boot copy from the external drive onto the iMac itself…?

thanks, David - yes, I did try that, but it said the Macs or operating systems were incompatible, or something like that. I read on an Apple Support site thread that migration assistant doesn’t always copy over EVERYTHING and you may not end up with a bootable disk.

Although, (up until now, possibly), why try and replace something that isn’t broken?
