Post Re: iMac os X utilities ?

OS X El Capitan is the last OS your iMac will support. If it doesn't already, add 8GB of ram and maybe a SSD. I'll go a long way in just normal day to day usage. My recommendation, obviously you don't have to.

Since your on a Windows machine. Use Etcher to flash the InstallMacOSX.dmg image to a USB stick. Ignore the missing partition table popup and hit continue.

After Etcher does it's thing, just pop the USB stick into the iMac and turn it on. Since there is no OS, it should just boot the USB stick.

If not, turn off iMac and hold Option (Alt) ⌥ key immediately after turning on the iMac.

As to how you format your drive, in Disk Utility select your internal drive (left hand side) and choose erase. Once the popup appears, select Mac OS Extended (Journaled) for the format option. The name option is up to you, leave Scheme as is. Click Erase and wait till finished.



Exit Disk Utility and once back on OS X Utilities menu, just select Install OS X and your on your way to a clean install of El Capitan.
