iBrave provides complete repair and upgrade services for iMac models from 2012 at our Lisbon and Cascais locations. We diagnose slow performance, startup failures, overheating, unstable graphics, power faults and storage errors. Depending on the configuration, we can replace an HDD with an SSD, increase storage capacity and upgrade RAM where physical access and model design allow it. Power supplies can be repaired at component level or replaced. We also service logic boards, cooling systems and graphics faults, including graphics-chip replacement when diagnostics confirm that it is appropriate. Display replacement is available when a compatible panel can be sourced. For damaged or non-starting systems, we provide microsoldering and attempt data recovery from the installed drive. Every repaired iMac is tested for startup, temperatures, storage health, display output and port operation.
