For a couple of months now my 24" iMac screen keep misting up behind the glass around 30 mins after booting - anyone know a resolution for this?
It is common to get condensation between the display and front glass panel, if it is humidity and cool in your office or home.
A few things that you might try, are
1. Reduce the level humidity with a dehumidifier.
2. Leave the iMac on longer until the condensation dissipates.
3. Remove the front panel yourself and clean between the display and glass.
Will Apple replace the screen even though i've had it around 4/5 years now?
No, but if you contact your local Apple Store or AASP you can schedule an appointment to have it dried and cleaned.
