Bought a
2015 5K iMac brand new at the start of 2017.
Used for a year with 10.12 Sierra absolutely no image retention, even when leaving the screen on all day long and nothing moving.
Just updated to 10.13.3 High Sierra. Holy crap.
Can't leave anything on screen for more than 5 minutes without image retention. Removed all desktop icons to stop them burning in. This is absolutely ridiculous.
As someone who's had to return 3 x 2017 macbook pros within a year due to the dust under the keyboard issue, I am gobsmacked at how much of an effect Tim Cook closing down Apple's quality & testing team has had across iOS & macOS.
Sick of updates breaking my Apple products, then Apple playing dumb and wanting me to pay for their idiocracy to replace with something they're going to break again.
This latest issue is just an absolute joke considering these are image editing machines predominantly.
I made a post here on Apple Support Forums about the situation but have had to be very careful with the wording. Moderators keep removing the post, stating things like "
what is image burn/retention? removed as it is speculation"!!
