In 2012, Apple redesigned the iMac with a slimmer form factor. The new iMacs from 2012 onwards have thinners sides which measures only at a few millimetres. While the design is stunning, users have been posting in forums about the iMac 27″ tilting issue and hinge issue. The iMac tilts forward involuntarily after a few months to 24 months of usage. The screen can no longer be adjusted to its normal position.
Given Apple’s supposed track record for durability, the cause for this issue is surprising. Guess what? This tilting issue occurs because Apple used weak plastic L-shaped spacer to secure the spring mechanism!
Some owners of 27″ iMacs who are affected and have dissembled their iMacs to attempt DIY solutions were appalled that Apple used plastic L-shaped spacer to secure the spring mechanism as the entire hinge, the nuts and the spring were made of strong metal. Apple even used an excessive amount of 9 screws on the bottom and 6 screws on side of the hinge to secure it to the iMac to prevent the hinge from dislodging, but used plastic to hold the spring!
The plastic that Apple used does not even appear to be strong ABS plastic. Some users the iMac 27″ tilting issue and hinge issue is a conspiracy by Apple to earn more money for repairs. This issue seems to plague only the 27″ iMac models. The possible reason is because the iMac 27″ hinge needs to bear more weight than the 21.5″ iMac, so the 21.5″ iMac appears unaffected.
