@streakmachine I was having trouble getting Leopard onto a eMac that had been given to me. There was something out of whack with the DVD drive. So I used Remote Disc and installed it from the fast DVD drive on the G5 PowerMac.
Downloads folder reduced from 1.09 GB to 37.2 MB by way of file transfers to correct locations, external drives & savage culling. Also sorted 12 years of web receipts.
I've let the Downloads folder on the MBA build up to over 1 GB, time for a cull.
@matigo I'm not so sure of that…… It's possible that it did end & was immediately replaced by an almost-exact copy. The only difference is objects are a few inches further away than is expected.
@sumudu I knew something was happening, fireworks & dogs barking. Cats just can't be bothered with fireworks, or at least my can't be. She sat on the end of my bed, swivelled an ear towards the sound then went back to her ablutions.
When the Men's Shed group bought the iMac in Oct 2015, it cam with the standard wireless Bluetooth keyboard. I replaced it with one of my two aluminium keyboards & supplied a cheap USB DL DVD burner to make up the price/value difference between the keyboards.
Over the Xmas/New Year break I have the iMac at home for security & updates. I intend reclaiming the aluminium keyboard & replacing it with a white plastic 
keyboard instead. Several users in the Shed say they prefer long-travel keystrokes.
TIL I can edit the white balance of pics taken on my Ricoh R10 digital camera while they're still on the camera/SD card.
