Hi. I hope someone can help. My iMac freezes constantly, and will only ever get through one or two operations before it...

Hi Solved. At last. With thanks to Dan - for taking so much of your time to advise me. The one constant in everything I’d been doing was trying to reinstall from the original Mac OS X 10.06 Snow Leopard DVD. It was what came with the iMac originally, so would be the best option … you’d think. What is it they say? If you keep doing the same thing you keep getting the same results! So change of tack; I created a boot USB for Mac OS 10.12 Sierra using TransMac on my PC and have installed that instead. (Links for doing that below. Ta DA! Absolutely painless install process, and the system is running perfectly. I’m on it now. Officially my mid-2010 A1311 Intel i3 3.03 GHz iMac with 4GB RAM doesn’t support Sierra, but everything seems fine. If it continues to be stable I’ll upgrade the RAM to 8GB to bring it closer in line with what’s required for Sierra.

Hi Anika Those screws need special screwdrivers; a set (works for Apple’s and PCs) costs only a few dollars. Many dollar shops have them. Your MacBook is damaged from someone over-tightening the screws, and using the wrong screws it seems. Is this how you put it in your bag? Regards, Adrian.

Hi. Do you mean that water is constantly dribbling into the bowl? This is very likely a worn seal. I've fixed this by replacing the rubber seal that sits at the bottom of the cistern. You'll need to lift the flush mechanism out, to get to the seal. Normally there are clips that hold the flush assembly and the cistern together. Get the assembly out, turn it upside down and you'll see the seal. There are different sizes, so take it to your local hardware shop to get a matching replacement. Very easy job to do. Regards, Adrian.
