My i9 MacBook Pro A1990 runs incredibly slow — is this throttling or a hardware fault?
The i9 A1990 is known to throttle below base clock speeds under sustained load. In Bali's heat, this is worse than in cooler climates. First, reset the SMC (hold left Shift+Control+Option+Power for 10 seconds). If throttling persists abnormally, we diagnose whether it's a thermal paste issue, fan failure, or a deeper fault — all fixable.
The T2 chip on my A1990 seems to be failing — what are the symptoms?
T2 failure symptoms include: the machine won't boot (stuck at Apple logo), Touch Bar doesn't appear, incorrect battery reading, kernel panics with T2-related errors, or bridgeOS crashes. First step is a T2 DFU restore via Apple Configurator 2 — this resolves firmware corruption. Hardware T2 failure requires board-level repair.
Can you recover data from a MacBook Pro A1990 with a dead logic board?
It depends on whether the T2 chip is functional. The T2 holds the encryption keys for the SSD — if the T2 is dead, data recovery is effectively impossible. If the board failure is power-related but the T2 has residual function, we attempt chip-off techniques. This is why we always emphasize: back up before coming to Bali.
How does the butterfly keyboard on the A1990 compare to the A1707 — is it more reliable?
Slightly. The A1990 uses third-generation butterfly keys with a silicone membrane barrier over each key, which Apple added specifically to reduce debris ingress. It helped in dusty office environments, but Bali's fine beach sand still finds its way through. We still replace A1990 butterfly keyboards regularly — they're not reliable enough for Bali's environment.
Is it worth repairing a MacBook Pro A1990 in Bali or should I upgrade to Apple Silicon?
For most repairs (battery, keyboard, screen, Touch Bar), it's worth it — the A1990 is still a powerful machine for demanding workloads. GPU or T2 chip repairs are higher risk and higher cost — we'll give you an honest breakdown of recovery probability and cost versus upgrade value before starting. No surprises.
