Symptoms
- Screen doesn't stay open at the angle you set it to
- Screen wobbles noticeably when typing or moving the laptop
- Hinge feels loose, gritty, or makes noise when opening/closing
- Display flickers or has connection issues that change with lid angle
Likely causes
- CommonNormal wear on the hinge mechanism after years of opening and closingHinges are mechanical parts that loosen gradually with repeated use.
- PossibleA hinge that was already weaker from a manufacturing tolerance or minor prior damageSome units may wear faster than others.
- PossibleScreen flickering or display issues developing from a stressed display cable due to hinge loosenessA loose hinge can eventually strain the cable that runs through it.
- PossiblePhysical damage from being opened forcefully or from one sideUneven stress on the hinge accelerates wear.
- Less commonA design-specific issue known on certain MacBook model yearsA few generations had more hinge-related complaints than others.
What to do
- Avoid opening the laptop from one corner; use both hands or open it from the center front edge to distribute pressure evenly.
- Note whether display flickering or connection issues happen specifically as you adjust the screen angle, which suggests the display cable is being affected.
- Avoid forcing the screen past its normal range of motion.
- If the wobble is mild and purely cosmetic/annoying without display issues, it may be safe to keep using while planning a repair.
- If flickering or display glitches occur with lid movement, stop adjusting the angle repeatedly and get it looked at soon to avoid further cable damage.
- Back up your data as a general precaution before any hardware repair.
- Research repair costs for a hinge or full top case replacement for your specific model, since this varies by MacBook generation.
- Schedule a repair sooner rather than later if you notice display issues developing, since a damaged display cable is a more involved and costly repair than the hinge alone.

When to call a pro
This is a mechanical repair best done by an Apple-authorized shop or experienced Mac repair technician, since it often involves replacing the hinge or full top case assembly.
Safety
Use caution
Avoid continuing to flex or force a wobbly hinge, since this can worsen damage to the internal display cable that runs through it.
