How to know it's this
These are the symptoms that point at iMac software / macOS repair. Match them against your iMac, then book a free diagnosis — we confirm the actual fault before quoting.
Stuck on the Apple logo or progress bar
A corrupted system or a failing drive. Often fixed with a data-preserving reinstall.
Folder with a question mark at boot
macOS can't find a startup disk — a software fault or a dying drive; we diagnose which.
Kernel panics / random restarts
Software conflicts, a bad update, or sometimes underlying hardware — we rule each out in order.
Extremely slow, freezing, or won't update
A corrupted system or a struggling drive; a clean macOS install usually restores speed.
Why iTweak for iMac
Most repair shops won't touch an iMac. Apple's quote is usually a logic-board swap costing more than the iMac is worth.
iMac is an all-in-one — display, logic board, SSD, RAM, PSU, and chassis are bonded together in a way that intimidates most repair shops. Apple Authorised Service Providers will quote a full logic-board swap for any board-level issue (cost: ₹40,000+). iTweak does component-level work: replace the failed GPU chip (not the whole board), upgrade the SSD without breaking the display bond, replace the fan + thermal paste without damaging the 5K display ribbon. We've been doing iMacs since 2010. 1-year warranty on most repairs.
- Component-level board repair — not assembly swap
- Vintage iMac (2011–2014) GPU failure — our specialism
- 5K / 4.5K display work, bonded panels preserved
- 1-year warranty on most repairs
What iTweak fits — across every iMac repair
iMac repair is the clearest example of where independent specialists beat AASPs on price and engineering. The AASP quotes a "logic-board replacement" because Apple's parts catalogue lists the whole board; we do the actual repair.

How an iMac repair works at iTweak
iMac repairs are bench-only — they need proper display-separation tooling and ESD-protected work. Free FedEx pickup pan-India in iMac-grade packaging, or walk into our Marathahalli or Andheri centres.
1Tell us the issue
Book online, call, or WhatsApp. Describe what's wrong (no display / GPU artifacts / SSD swap / slow / fan loud). Tell us the model — About This Mac → System Report → Model Identifier confirms it (e.g., 'iMac17,1').
2Free FedEx pickup or walk-in
Free insured pickup pan-India in iMac-grade packaging (custom-fit foam, ~30kg shipping weight). Or walk into Marathahalli (Bangalore) or Andheri (Mumbai). Typical round-trip: 6–8 working days from anywhere in India (iMacs are slower than smaller devices to ship).
3Diagnose and quote
Apple Diagnostics + bench-level testing (multimeter, microscope, thermal scan). We confirm the actual fault — GPU vs board vs SSD vs PSU — before quoting. Written quote, itemised, approve or decline.
4Component-level repair
Display panel safely separated using suction + heated mat (no heat gun). Component-level board work — chip replacement, capacitor reflow, BGA rework where needed. SSD swap where requested. Reassembled with Apple-spec adhesive.
5Test, calibrate, return
Apple Diagnostics post-repair, thermal calibration, display calibration. 1-year warranty paperwork. Return courier or walk-out.
If it’s not the battery, you don’t pay for the swap
Our 80-point Phonecheck diagnostic runs before any disassembly. If the issue turns out to be elsewhere — charging IC, board fault, software — we tell you, refund the booking, and quote the actual fix. No upsells.
- Pre-repair diagnostic on every booking
- Written quote before any work begins
- 100% refund if mis-diagnosed
- No part used without your sign-off
What our customers say

“Classic 2014 iMac GPU failure — black screen with checkerboard pattern. Apple said it was uneconomical to repair. iTweak replaced the GPU chip directly (not the whole board), saved ₹40,000. Six months on, no issues.”
Manish T.iMac 27 (2014) · Bangalore“Wanted to upgrade my Fusion drive to a pure SSD. Apple said it wasn't possible. iTweak did the upgrade without breaking the display bond. Boot time went from 60s to 8s.”
Anitha R.iMac 21.5 (2017) · Mumbai“Fan was running constantly. iTweak replaced the fan and re-pasted the CPU + GPU thermally. iMac is silent again. Sent via courier, took a week door-to-door.”
Sandeep G.iMac 27 (2019) · Chennai“Won't power on after a thunderstorm. iTweak diagnosed it as PSU + a single logic-board chip — fixed both, didn't replace the whole board. Significantly cheaper than the Apple quote.”

FAQ
Process, warranty, data, models — the imac software & macos repair questions our iMac techs hear.
We try the data-preserving route first — a reinstall over the top that keeps your files. We only erase as a last resort, and we always back up or recover your data first where the drive is healthy enough.
Usually not. Even when macOS won't start, the files are typically intact on the drive. We can recover them before reinstalling, or off a failing drive where needed.
That's exactly what the diagnostic determines — many 'software' symptoms are a failing SSD/hard drive. We confirm before quoting, so you fix the real cause.
