Yes. While Apple Authorized Service Providers often only offer full board replacements, our senior technicians specialize in component-level logic board repair for the latest M2, M3, and M4 models. We can diagnose and replace failed power-rail capacitors or shorted chips, preserving your original board at a fraction of the cost of a replacement.
Even with Apple's integrated T2 and Apple Silicon (M-series) encryption, data recovery is often possible. By restoring power to the logic board or utilizing specialized NAND bypass protocols, JTG Systems successfully recovers data from "dead" Macs that other shops consider lost.

Most repairs completed within 24-48 hours with same-day service available for many common issues.
Using your laptop on beds, pillows, or blankets blocks cooling vents and can cause severe overheating. This is a serious fire hazard and can permanently damage your device. Always use on hard, flat surfaces.
If your MacBook appears swollen or bulging, stop using it immediately. A swollen battery is highly unstable and poses a significant fire and explosion risk. Bring it to us for safe handling and replacement.
Always shut down or put your Mac to sleep before placing it in a bag or backpack. An active Mac in an enclosed space can rapidly overheat, causing battery damage, potential fire hazards, and permanent hardware failure.
